It's an AI-native email client. Launching soon!

My goal is to help people get done with email faster, so that they can get back to doing other stuff. A lot of the features are designed around this goal: unified inbox, AI summarization, AI email drafting, etc.

Some of these are table stakes but I think there's also an opportunity to significantly revamp how email is done in the AI age. Imagine having your own personal assistant that goes through your email and surfaces the highest priority things that you need to know automatically.

How are you measuring "lightweight" here, what do you mean by it?

(Not doubting your claim this just seems one of those words that means many different things depending on the context.)

Primarily bundle size. Pglite is a 3 MB binary, SQLite is <1 MB.

I was evaluating local storage solutions a while back and I tried setting up PGlite, but unfortunately I couldn't get it to work in Next.js with Turbopack in a web worker.

I've been using SQLite locally instead with wa-sqlite and it's been working great for my use case so far. It's also more lightweight.

I'm working on https://www.fluxmail.ai, a modern, AI-powered email client.

I think there's a lot of potential for AI to improve the way we organize and manage our inboxes, while still letting us keep control over it.

What I've learned is that there are a lot of little features that make up a good email client that you may not even think about when using one, like threading, quote blocks, even what email address(es) to autofill when you reply to an email. For an app you use potentially for hours a day, the polish and "last 20%" makes a huge difference - and takes a while to build!

If you have any feedback, especially on what features are most important to you in an email app, I'd love to hear it :)

I'm working on 2 projects right now:

1. Fluxmail - https://fluxmail.ai

Fluxmail is an AI-powered email app that helps you get done with email faster. There are a couple of core tenets/features that it has, including:

- local-first - we don't store your emails and we make interactions as fast as possible

- unified inbox - so you can view emails from all your email addresses in one place

- AI-native - helping you draft emails, search for emails, and read through your emails faster

I'd love to hear if these features resonate with you, or if there are other features that you feel are missing from your current email app.

2. ExploreJobs.ai - https://explorejobs.ai

This is a job board for AI jobs and companies. The job market in AI is pretty hot right now, and there are a lot of cool AI companies out there. I'm hoping to connect job seekers with fast-growing AI companies.

https://notabase.io - a note-taking app for networked thinking.

It supports page stacking, linked references, block references, a graph view, and all that good stuff. Think of it as similar to Roam Research / Obsidian.

It's also open source so you can self-host it. Here's the code: https://github.com/churichard/notabase

I'm hoping to add support for shareable links soon. Open to other ideas or feedback!

RichardChu commented on Switching Rich Text Editors, Part 1: Picking Tiptap   ashbyhq.com/blog/company/... · Posted by u/dbbk

When evaluating rich text editors for the note-taking app I started about a year ago (https://notabase.io), I ended up going with Slate because of its flexible schema and customizable plugin architecture.

I sort of regret that choice now. I ran into a lot of bugs when integrating it which I had to manually work around; issues go months without being addressed; and there still isn't good cross-platform support, especially for Android. With a more active contributor base, Slate could be a fantastic library, but I get the feeling that it's in maintenance mode now, with not many major changes in the past year and a v1.0 still far in the future.

Tiptap looks like it might be a good choice now, but I find it off-putting that I can't insert links in the demo editor on Tiptap's website (https://tiptap.dev), especially for my use case (a note-taking app whose core concept revolves around links).

RichardChu commented on Ask HN: What is your “I don't care if this succeeds” project?    · Posted by u/JNRowe

I'm working on an open source note-taking app called Notabase [1].

It's built primarily for my use - I just never liked most existing note-taking apps and wanted to make one that's easy to use and fit the way that I think. I made it open source [2] so other people can build on top of my ideas, and released a hosted version so that other people can use it if they like it.

It would be nice if other people found it helpful, but regardless it's something that I intrinsically enjoy working on.

"Note: by default, Notabase has a cap on the number of notes you can create. You can circumvent this by inserting an active subscription for your user id in the subscriptions table."

Not really "self-hosted", then.

RichardChu · 4 years ago
Maybe it's unclear, but you just need to insert a row in the subscriptions table with the value "ACTIVE". You don't actually need to have a real subscription on the hosted version of Notabase.

Besides, if you know how to code, it's simple to change the max number of notes to something like Number.POSITIVE_INFINITY anyway - but adding a row in the database is likely easier so that's what I recommend.

It may be a bit of a hassle, but I do this because the codebase for the hosted version and the self-hosted version is the same, which makes it easier for me to maintain. In the future, I may make a separate self-hosted version so that this step can be skipped.
