We believe your tools should amplify your thinking, not fragment it.
For you
Own your data
Everything lives as files on your disk. Delete the app, keep your work.
Use any model
OpenAI, Anthropic, local LLMs. Your choice, your API key.
Preserve authenticity
No middleman. Direct connection to your tools and models.
For developers
Free and open source
Audit the code. Fork it. Make it yours.
Blazing fast
Built with Rust, Svelte 5, and obsessive performance optimization.
Built on tomorrow's stack
CRDTs, local-first architecture, and the bleeding edge of web tech.
Built different from the ground up
One architecture, endless possibilities
One folder. All your data.
Everything lives in a single directory on your machine. Plain text files and SQLite databases you actually own.
Local-first by default
Your transcripts, notes, and ideas never leave your machine unless you want them to. No cloud lock-in.
Works with tools you already use
Because everything is plain text and SQLite, your entire workspace is compatible with the tools you already love.
Infinite workflows, zero lock-in
Your workspace plays nicely with the tools you already love. Edit in VS Code, search with grep, version control with Git.
Obsidian
Edit your notes in your favorite knowledge management tool
grep & ripgrep
Search your entire workspace with blazing fast Unix tools
Git
Version control your ideas, notes, and transcriptions
VS Code

Your favorite tool
Plain text and SQLite mean your tools work too. No proprietary formats.
Frequently asked questions
How is this different from Obsidian?
Obsidian is a Markdown editor with sync. Epicenter is a local-first storage substrate: multiple apps share the same CRDT-backed data folder. Your notes, transcripts, and chat histories all live together and sync conflict-free.
Is my data encrypted?
Epicenter Cloud doesn't encrypt your workspace data. The sync server is a trusted relay that reads plaintext, which is what makes server-side search and AI work. If you want a server that can't read your data, self-host it: then the only machine holding it is yours. You can also run entirely offline.
Can I self-host?
Yes. The sync server is open source and runs on Cloudflare Workers or any WebSocket-compatible host. You can also run entirely offline; sync is optional.
What happens if I stop using Epicenter?
Your data is plain text and SQLite files on your disk. Open them with any text editor, query them with any SQLite tool. No export needed; the files are the product.
Software for people who think
We're building an alternative to apps that fragment your thinking across a dozen cloud services. Epicenter is for people who read deeply, write to think, and build to understand.
Every tool is open source. Your data stays in plain files you control. Choose your own models, host your own services, or run everything locally.
