Show HN: Ichinichi – One note per day, E2E encrypted, local-first

Nice idea for a diary app. "Can't edit yesterday" is off-putting for me. Such a constraint should not be something a software imposes on you, should be a person's mental policy, if they so wish. I want to have full control over my data, without arbitrary restrictions. Another thing is easy deployment. Would love to give it a shot, but I need something like that to be available on both mobile and desktop, that would mean server deployment with all the headache of managing a server and backups...

I am using daily notes currently with Obsidian + Calendar plugin. Also E2EE, available on all devices, no problems syncing, plain-old files so I am not afraid of vendor-lock and can backup any way I want.

Love it! The name, the design, the concept, the open source codebase, everything! It’s less like a note taking app and more like a diary writing app. I think that’s very neat and has its own niche.

Love the local-first, browser-based nature of it. If you ever consider making a native app for it, consider looking at antinote (https://antinote.io/). Been using it for over a year. It’s the only notes app that I haven’t uninstalled or forgotten about. I think the simplicity of it is what draws me to it. I feel it aligns with your philosophy for this app!

Thanks for sharing Ichinichi with the world!

MacOS only, I gather? That's too bad. My next machine will be Linux, and I rather like the concept of the application.

It installs easily under Linux.

Thanks so much!

Antinote looks awesome! Love how minimalist it is and how they demo all the features on the landing page. I’m going to look into making ichinichi into a desktop app.

If you like the open-source codebase, then why are you peddling your closed-source paid platform?

You're allowed to like both. Antinote is very unique, and devs should be allowed to charge for their work if it's a quality app with a really polished UX.

Also, its not theirs.

Nice, and I like the idea that the past is fixed, but ... is there a way to define the point of rollover to the next day? My "days" sometimes end at 0:50 for example and not at 23:59. So I might summarize the day a bit after midnight.

Good idea, I can do that!

If you want to avoid too much choice, but still want the "the past is immutable" feel, you can prevent editing after noon next day or similar.

Days "roll-over" when you sleep, so it should be safe to rollover notes which haven't been edited for 6 hours. That way there is no fixed rollover time.

But then if you edit a note in the morning to add something, by night it'll be locked.

Having the default "midnight" be something like 3AM would get you 90% there without any UI changes

Many lootbox phone games do rollovers at 4AM local. Your sleep cycle would be seriously broken if you're awake 4:00 +/- 0:30

I just use a .org file, with git to retain old versions if I edit something that might be of later relevance.

For this purpose I wrote an app called Five Years Back: I can write one entry daily, but I can see what I wrote on this day for the past 5 years. My writing streak is… 1399 days as of today. Only me is using the app.

Good job and good luck!

Wow, that’s commitment right here. I only started journaling (dogfooding ichinichi) from 1st January this year. It’s nice to see an unbroken streak. Gonna check out Five Years Later!

That divider with a time stamp on the right is very cute!

I am looking for, in a sense, the opposite of this app. I need an AI-powered IDE-like editor for markdown files. I keep a ton of research notes in markdown and when it comes to writing reports for admins and such, I need something to help me make sense of them, integrate them, reformat, do a "semantic refactoring" across files, diffs. etc. I saw people use Obsidian with some plugins, but I think I need Cursor for markdown. Any suggestions?

I'm building this exact thing. Heavily inspired by obsidian (and the obsidian workflow where you launch claude code in your vault), but with a leaner UX, and a web-first app. Not launched yet, but I'll let you know when I do.
