note-taking software doesn't need to be bloated or slow! (yes this is actual 1x speed 🔥)

The best API is no API. Instead of MCPs and CLIs, Markdown Mirror will let agents edit state directly through files while the app translates those changes into multiplayer operations behind the scenes. Files as the API.

What if agents could just write to local files and changes show up in a real-time multiplayer web app?

1987 workstation aesthetic was peak productivity energy :) Vibe Shift works great with the Terminal panel too

notes as a virtual file system, with in-app terminal (desktop web). agents can use the same vfs bash so the whole workspace becomes programmable.

Love the Omarchy aesthetic. Fits Thymer's vibe so well, added a little extra when running it on Omarchy: auto theme matching. Bring back fun as a feature!

Turns out the "IDE but for notes and tasks" is also becoming my... IDE! More and more I just make notes and boards with specs of what needs to be built, connect a bunch of code agents to thymer all working in parallel, have them pick up open tasks, build it and update progress back in the notes.

Local AI agents really feel like a turning point. That's awesome but tbh I'm just as excited about the terminal/CLI aesthetic comeback they're causing 🤩

For the Thymer alpha testers: the MCP announced last week is now available, see thymer.com/mcp for more. It's a small companion app that talks to your Thymer (web) app and provides AI agent access (MCP), as well as a command-line interface for terminal access.
