Overwhelmed? Us too.
Limestone is a free, local-first note-taking and productivity app (i.e. notes, tasks, projects) from Voithos Labs, built for people who just want their tools to get out of the way.
- Free to use, source on GitHub
- No accounts
- Local-first, works offline by default
We have tons of experience making accessible tools, for everyone. All our attention goes into the details.
Early access: expect bugs and major changes between versions.

Polished Surfaces
We love the idea of markdown, but in practice markdown editors feel clunky next to Word or
Docs. We in-housed our editor, Aragonite, to give a polished surface to your files.
Automatic edit history, speedy full-text search, pretty interface.
Project Oriented
As you've probably learned in your short and painful human life, keeping organized is better than needing to get organized, and complicated organization systems never last. We keep it dead-simple, documents (md, PDFs, images, recordings, etc.), projects, and tags.
It's hard to explain it all in writing, just take a look.
