The responses here so far have been amazing; working hard on your suggestions. I wanted to also share that Dlog received its first sales and founding supporters from Show HN in the last 24 hours; I can't thank you enough for the encouragement and motivation.

I'm a bit intimidated by the long list of things this app is trying to do.

Is it a project management tool? If so, how do I share everything with my team? Project management tools are defined by their collaboration and workflow features.

Is it a journaling tool? If so I absolutely don't want my team in the tool, and so can't use it for project management. How does it encourage me to do better journaling and build the habit?

Is it a wellbeing tool? How well does that work if I don't put my project management in there? If I can't use it for half the stuff it's intended that I will, then it might be of limited use.

Is it a coaching tool? Why would I want to use an AI coach over a mentor or human coach?

Is the AI required? I have no idea how many tokens I'd need to use something like this? Do I need a million a day or a million a year? (When coding I tend to use ~10-50m input tokens per session, will this cost $500 per day to use?) If the AI features are optional, what is the product without it?

Overall my feedback is that there's a lot here, and I think the product needs a much clearer story. The copy on the site is long and rambling and needs a lot of tightening up. Personality is good, but in moderation.

Thanks so much for the feedback! Below are my responses.

- Is it a project management tool? If so, how do I share everything with my team? Project management tools are defined by their collaboration and workflow features.

Dlog is not meant to be shared with a team; I will look at enterprise versions later on; but for now, a Blog is public, a Dlog is private. So, the project management definition here has been relaxed to mean a journal with a reminder list(or lists) organised by goals; the timeline view allows you to track these.

- Is it a journaling tool? If so I absolutely don't want my team in the tool, and so can't use it for project management. How does it encourage me to do better journaling and build the habit?

It absolutely is a journaling tool, and so your team can never view these; I am working on a feature for you to tag whether a journal is for work; this will impact the coach responses; and could be used later on for the enterprise version (targeting this for next year at some point). In terms of encouraging you to do better journaling, when you start a New Dlog there at the top left is a toggle called “Journal Coach”, there you can get prompts on the 4-rings (i.e. the Dlog Model at the heart of the app that trains your Dlog Coach is based around the 4 main constructs, Personality, Character, Resources and Well-Being); or ask it for feedback on whatever you are journaling about.

- Is it a wellbeing tool? How well does that work if I don't put my project management in there? If I can't use it for half the stuff it's intended that I will, then it might be of limited use.

Dlog is based on the 4 constructs of Personality, Character, Resources and Well-Being. The Coach will give advice from day 1 after you have taken the baseline survey. It doesn’t matter if you do not use the project tool and just use it for journaling. Projects work in tandem with goals as well. I am keen to hear what features you’d like in the project management side or any other area you would like to see improvements in. I do recommend that you watch the youtube video (if you haven’t already) I made for Show HN in the original post. That should (I hope) explain how this works, but it is unvarnished and 15 minutes long, so I need to get a clearer explainer about the main story here.

- Is it a coaching tool? Why would I want to use an AI coach over a mentor or human coach?

The AI coach is deeply informed by the in-built SEM model; the model I developed during my PhD; based on sentiment analysis scoring of your journals (including projects, but again, it’s not required). There are many buttons available in the coach, check out the video for an example of the output, for example, it can say how to “Strengthen Relationships” (that’s the example given in the video), by looking at which important people in your life over time have impacted your well-being positively or negatively over time, and provide a quantitative and qualitative analysis of this; giving advice in terms of how to improve these relationships and protect your mood and affect. Any responses you ask it the Coach will always try to improve your resources and well-being, focusing on the 4 rings and the Dlog model.

- Is the AI required? I have no idea how many tokens I'd need to use something like this? Do I need a million a day or a million a year? (When coding I tend to use ~10-50m input tokens per session, will this cost $500 per day to use?)

Unless you’ve written over 10 million words its highly unlikely that you’ll use a million tokens in one day. 1 million tokens costs 5.99. But if you dm me your email address that you’ve used to sign up with Dlog I’ll give you 1 million and a free perpetual license so you can use Dlog for free forever (excluding the tokens). I’m doing this for all Show HN readers who write me directly.

- If the AI features are optional, what is the product without it? Without the AI, Dlog is still a useful journaling and projects too. You can actually use another website I made called dlog.site that has no AI features, meant for PC users to use; I'm not really promoting that at the moment as I'm trying to get feedback on the primary Mac OS.

- Overall my feedback is that there's a lot here, and I think the product needs a much clearer story. The copy on the site is long and rambling and needs a lot of tightening up. Personality is good, but in moderation.

Agreed. Working on it!

Again, many thanks for the very useful feedback.

Dr J.

I suggest you practice writing more concisely.

The comment you replied to said that “…there's a lot here, and I think the product needs a much clearer story. The copy on the site is long and rambling and needs a lot of tightening up.”

In response, you wrote more text than I am willing to read — even though I was interested in your answer.

Fair point—my last reply was too long. Here’s the concise version: • What it is: Personal journaling + goals; not a team PM tool (no sharing yet). • Habit & wellbeing: Baseline + weekly model → small, specific nudges. Projects are optional. • Coach: Optional AI that summarizes your patterns; complements (doesn’t replace) a human mentor. • Privacy & cost: Journals stay on-device; by default no raw text leaves the Mac. AI is per-prompt/opt-in; typical use is modest. (HN readers can DM/email for a perpetual license + tokens to test.) • Action: I’m tightening the site copy and adding a clear “why” explainer.

Thanks for the nudge.

Hi I'm nobody and the stories on here constantly remind me of this old parable. There once was a man who was afraid of his own shadow and who hated his own footprints. Somehow he got it into his head that if he could just run fast enough he could outrun them, so he ran and he ran, but no matter how fast he ran his shadow stayed by his side, and the faster he ran the more footprints he made. Somehow the man got it into his head that he just wasn't running fast enough, so he ran and he ran and he didn't stop or rest and he died. Not knowing that standing still is how to stop making footprints, and that resting under a tree is how to stop making shadows, is just so tragic.

The only thing I hate more than the idea of a life coach is an AI Life Coach.

It takes all kinds to make the world go round, of course, but the entire vibe of this part of contemporary culture grosses me out and depresses me.

I love the vision. From what I can tell, you're building something that I think should exist and we have the technology for now. I think we need a place to put our 3, 5, 10 year goals, and some kind of process to keep us on track for that. And it's so personal, of course the LLM aspect needs to be local-only.

One concern I have is that I think I will need more than an empty "add Journal entry" nudge or prompt. I think I would want what a real coach would do/say. Something like, "How's the meditation/exercise/calling friends/making stuff going?"

Thanks for the positive feedback! The LLM aspect is using enterprise API from openAI, their policy is to not train on user data; I've used it extensively for the last year with my own personal diary Dlog data; pretty dry stuff to be sure. However, I will be working on allowing the user to use their own on device models; at the moment running local models is too memory intensive for most users so I need to do this once the models are more compact. Apple have recently allowed developers to integrate AI through their foundation model LLM but the token window is too short, 8K only if I recall correctly; and the responses just aren't that useful. The technology will improve and trust in openAI's systems should increase; we're early days here, but for now the main mechanisms for LLM we are has to be the enterprise openAI; there's nothing better IMO. Another thing I am working on in the short term is mechanisms to anonymise content and approve the prompt before it is sent; as well as a simple toggle that when switched on removes that journal from being included in Coach analysis. Thanks again. If you DM or email me and let me know the email you used to sign up with Dlog then I'll send you a free perpetual license so DLog is free to use forever, excluding the AI tokens; and I'll give you 1 million free tokens. Have a wonderful day. Dr J.

Questions while watching the video.

Calendar is central, but I use a Google calendar which is important to me. Connect it?

Seems like a "dlog" is a calendar entry. So is my "journal" broken up into separate pages, not a sequential document or blog?

2:30 ff, strongly suggest that for your next video you pre-script it to avoid fumbling and mumbling.

5:10 side note, interesting that your personality(?) model was from 2018, well before LLMs.

7:50 for an app to produce such output (impact of a friend on mood) you surely must do a copious amount of extremely frank journaling. When, and in what format? As scattered calendar entries? I'm confused how I fuel the app.

10:40 relating diary entries (reported activities and attitudes) to one's stated goals -- this is what I would expect an AI to do, and tell me about them rather than the reverse.

I'm sorry, I just don't see how I could use or adapt to something like this when I have a well-established diary/blog and calendar, it would mean changing many daily habits and adding what looks like a lot of detail work.

Thanks so much for your detailed feedback and for watching my rather unvarnished intro video with too many ums and ahs!

- Calendar is central, but I use a Google calendar which is important to me. Connect it? Dlog will use the default apple calendar which, if is your Google calendar, will display automatically. - Seems like a "dlog" is a calendar entry. So is my "journal" broken up into separate pages, not a sequential document or blog?

Not quite, a calendar event has a title and notes. The title of the dlog will be whatever you call it, the default is (if your name is anon) Anon’s Dlog. The notes of the event are where the journal entry is stored; along with Dlog tags such as goals, journal type, and sentiment scoring. - 2:30 ff, strongly suggest that for your next video you pre-script it to avoid fumbling and mumbling.

Yes, agreed, I made that very quickly yesterday. I’ll re-record it today. I still want to keep it quite unvarnished though as the HN mods told me that this is what Show HN community prefers

- 5:10 side note, interesting that your personality(?) model was from 2018, well before LLMs.

Yes, I never dreamed this would be possible until the introduction of ChatGPT. - 7:50 for an app to produce such output (impact of a friend on mood) you surely must do a copious amount of extremely frank journaling. When, and in what format? As scattered calendar entries? I'm confused how I fuel the app.

Yes, you’d just journal normally, as you have various important experiences you can journal about this in free form, stream of consciousness etc.; or use the guided four rings prompts in the Journal Coach at the top left of the Dlog entry area. It doesn’t have to be copious, or systematic, because the model is time series, it doesn’t require fixed repeated entries. If you use Dlog for a few days or weeks I’d be very interested to see if you found the responses useful. And again, if you send me a DM I’ll provide a free perpetual license so Dlog is always free for you to use.

- 10:40 relating diary entries (reported activities and attitudes) to one's stated goals -- this is what I would expect an AI to do, and tell me about them rather than the reverse.

The feature at 10:40 relates to just summarizing the entries that have been added to that goal; it is not related to the AI coach (which does what you’ve stated that you expect i.e. relates diary entries to activities and attitudes to ones goals) - I'm sorry, I just don't see how I could use or adapt to something like this when I have a well-established diary/blog and calendar, it would mean changing many daily habits and adding what looks like a lot of detail work.

Apologies, I do think the technical intro video is giving a lot of behind the scenes background information which may be overwhelming if you’re simply looking to journal and improve well-being.

I would gently recommend that you try it out for a few days and see that it’s fairly intuitive to use and well worth the process once you start seeing the insights from the coach (which get better over time).

Warm regards, Dr J.

This looks really cool! I would love to take you up on your offer to show hn viewers! Dm you my Dlog signup email?

Awesome. Yes, please do; or email me at johan@dlog.pro

I like the concept, but I bailed at "GPT 5". The only thing that has given me peace of mind and the ability to journal honestly and successfully is Obsidian, because it lets me own my data (as text files).

Thanks for the feedback. I love Obsidian. All your data is stored on device i.e., in calendar entries (a Dlog is saved in your default calendar, that's why you don't need to sign in to use Dlog; the title and text of a calendar event are repurposed in Dlog to be a journal; much like the reminders have been repurposed to comprise projects) and on the in app on device Rag database, it is not stored in the cloud etc., so you do own all the data; and it is not shared to the Dlog server which is only used to track token usage. GPT 5 is necessary for the moment; Dlog uses the enterprise API, so it doesn't train on your data. However, I know this is a major concern for many, so, in the short term I will be adding an anonymiser; and the ability to approve and edit prompts sent. If you do decide to sign up to use Dlog send me a DM with the email used to register and I'll send you a free perpetual license so Dlog will always be free (excluding tokens for AI use) and 1 million free tokens. Thanks again!

Please, both hackernews readers and the author take a closer look to see the cracks on the site. I'm fine with using AI generation, but it needs human review especially for legally binding stuff like the privacy policy.

1. Look at the concepts pie on the home page. The text in the pie is unreadable. Its overlapping and overflowing, white text clipping onto a white background with terms like "topic tagging" that are not an actual example. Its like no human looked at the image before putting it on the website. Maybe just a slip up, we all make mistakes, let's keep looking.

2. I didn't understand the data storage/privacy from the video, so let's look at the privacy policy. At one point the policy says "Do we receive any information from third parties?

No, we do not receive any information from third parties."

Right before later saying:

"journal entries or project-related text that you select are sent to the ChatGPT-5 thinking nano API operated by OpenAI."

Open AI *is a third party*! The answer is "Yes we send data to Open AI under these conditions". That's bad.

3. Lets look deeper. The privacy policy says they store 3 things with the first bullet point (in full) being "A unique user ID number that cannot be used to identify you." You're telling me a literal Identification (ID) Number can't identify me? Why does it exist? That is borderline nonsensical.

4. The video has similar vague stuff saying the data is processed locally after saying its going to chatGPT 5.

I'm giving harsh feedback because I want a project like this to exist, be done right, and succeed. I understand "ship fast and iterate". You're going too fast and you're not shipping an MVP, there is lots of feature creep.

Even when everything looks good, people should be hella skeptical about an app that wants to (potentially) harvest extremely personal daily journal logs. When every page smells like "I generated this and didn't fully check it" it makes me imagine how many hidden problems there are in the codebase.

- The kinda-rough AI video tells everyone "I don't have time to record a 5 min video of my own project". If you want me to believe you care, at least hire a narrator on fiver for $20 if you don't like speaking and/or showing your face. Why should I trust what you say you'll do with my most personal data when you don't even show yourself/show a human?

- There's only three important things: pricing, privacy, and the data analysis / coach. Leading with price is good/solved. What's missing is clarity about privacy. The hackernews post is much more clear, the website is not. I don't need more words, I need to know when the data is and is not shared and I need to be convinced you're responsible. Right now stuff like "Dlog’s private AI model" makes it confusing what's local and what's shipped to OpenAI.

- Even when explained clearly, privacy is going to be a problem. Let me use me use my own model/token/url. It's easy to point to a local URL that responds with data in the exact same format as GPT 5. That kind of feature is 10x more important than changing the color of the background.

- I'm not getting a coaching app because it has a good theme engine. Finish talking about coaching/analysis before going into themes and calndars etc. I don't even care how data is entered into the app, until after I know the useful things its doing. Give a real example of insight that changed your daily choices.

- I think you can do it, and I'm glad to see someone trying to meet this usecase.

Appreciate the detailed look. A few clarifications and immediate fixes: • Concepts pie: noted. It’s a minor visualizer and not a current priority; there are dozens of other charts in the Dlog Lab tab. I’ll queue a fix, but I’m focusing elsewhere first. • Privacy policy: you’re right—OpenAI is a third-party processor. I’m correcting the policy to say exactly when data is sent, what is sent, and under what controls (Enterprise API with no training/retention). I’ll also add a simple data-flow diagram. • Local vs cloud: journals live on-device; the SEM runs locally. Scoring only happens when you explicitly choose to score—there’s no background upload. I’m adding a per-journal “Include in Coach analyses” toggle, and a simple “Remove names” anonymizer (ships in the next few days) so names are stripped before any scoring call. • BYO endpoint: not on the near-term roadmap. I’m prioritizing clear privacy controls and product focus over supporting custom model URLs right now. • Copy/video: I’ll tighten the site copy to lead with privacy and analysis, and make the local vs cloud boundary crisp.

Thanks for pushing on clarity—fixes are in motion.

I don't do subscription based apps as a matter of principle if it has no business being a subscription based app

Fair enough. But, you may not have noticed this edit that was added to the original post which explains I am giving a perpetual license and 1 million tokens to all Show HN readers; i.e,. so no subscription.

For general users it's free for 14 days with 10K free tokens; then its 1.99 per month at the moment. However, for HN readers that DM me or email me (johan@dlog.pro) with the email they register with, I'll give a free perpetual license so there's no monthly fee; and add 1 million tokens.

Hey kstrauser, thanks for the first comment!

Can you let me know what would reduce the warning bells regarding the itsatrap.gif? Like, what gave you that impression? Really need to get this right.

For general users it's free for 14 days with 10K free tokens; then its 1.99 per month at the moment.

However, if you or HN readers that DM me or email me with the email they register with, I'll give a free perpetual license so there's no monthly fee; and add 1 million tokens.

Thanks again for the feedback, I'm glad you liked the privacy policy! :))

Oh! That's pretty reasonable. It's just that I've seen so many slick looking tools that go for waaaaaaayyyyy more than I'd ever personally consider paying for them, like "use AI to sort your CD collection for only $29.95 per month! For only a cup of coffee a day, you could have perfect sorting!"

Do you support Bring Your Own Key (BYOK)? If I'm the first to ask, I'm 100% certain I won't be the last. That a standard question we get from our own customers.

OMG that's ridiculous. I will definitely look closely at integrating BYOK. Do you have an app that uses BYOK?

That might've been an exaggerated example, but only a little! I've seen lots of tools add AI as a feature and immediately jack their prices.

Sure, lots of apps do that. For example, Zed (https://zed.dev/docs/ai/llm-providers) has a subscription plan but alternatively will let you plug in your own key and then provide the same features free of charge.

Awesome, I'll check that out! Thanks!!

Also, I added the pricing to the home page; hopefully this reduces those warning bells! Thanks so much, I hadn't considered that that would be a barrier.

Should include systems requirements on the download - I got a grumpy MacOS message about needing to do an OS update to run it. It's not a big deal but little frictional hiccups like that results in invisible abandonment.

Will do. If you do update your OS and try out Dlog do send me a dm and I'll give you a perpetual license and 1 million tokens to test out Dlog.
