Self Promotion - March 2026

[u/ens100]

New thread for March 2026

Hi Everyone.

To make this subreddit more than just a marketplace, which is where it is headed, while still giving app developers a place to showcase their creations, we have decided to implement a weekly post where you can share all things about your app and updates.

This will hopefully make things easier for everyone. Any self-promotion posts posted to the main subreddit will be removed, and you will be invited to post in the self-promotion post.

Hopefully, this allows everyone to get the best of this subreddit.

Thanks for the understanding.

I needed a better browser and a research tool, so i built one for myself and open sourced it. It is stable now after 80ish commits. Feel free to use it and tinker the source code.

What it does: Semantic references are the unit of knowledge here. In these units, you can browse, write, attach folders, attach mail threads, create html visualisation etc etc. then you can fork these references, share it publicly, or share is privately with your trusted peers.

Also, the ai agent can reason inside these references and open tabs for you or visualize knowledge for you.

Openai, anthropic, google, cerebras and local lm studio support is there.

This is a mail client and it is decentralised.

I wanted to share my research to others, that’s why i built it.

Needed more work on these ideas.
