People collaborate live.
Build pages, dashboards, galleries, databases, and tasks in Thymer's fast structured editor. Real-time, multiplayer, as an app or in the browser.
Markdown Mirror Coming soon
Real-time collaboration and local Markdown access. Both.
Write and plan in Thymer's multiplayer workspace while Markdown Mirror keeps a local mirror of plain .md files in two-way sync. Your existing agents, tools, and scripts can read and write files, working on the same live workspace.

The shift
More AI tools means more notes.
Meetings become transcripts. Chats become summaries. Agents produce plans, decisions, drafts, and follow-ups. We're generating more docs than ever, and it's splitting our knowledge into two silos: human-friendly or agent/tool-friendly.
Thymer is both.
Live local file sync
A live reflection of the workspace as plain Markdown, kept in two-way sync. Edit on disk or in Thymer and changes flow both ways. Portable, no lock-in.
A single source of truth.
Agents and tools pull plans, notes, and docs straight from the workspace and feed their work right back into it. People and AI collaborate in one place, never on stale copies.
The upside of local tools
Keep Thymer as your source of truth while using the tools that work best on plain files.
- Run terminal tools like ripgrep, qmd, or a quick script
- Hand work to tools like Claude Code or any local AI
- Open by design: bring any tool or agent, not a closed in-app AI
- Import, back up, and export from a plain folder
- Automate using your existing toolchains
The best API is no API.
Agents can change state by editing the files directly, and Thymer turns those edits into real-time, multiplayer operations. Sure there's an MCP if you want it, but with raw file access there's nothing to wire up: no custom SDK, no extra context overhead.
Files as the API.
More than Markdown.
While tools and agents work directly with the files, your team gets a new editor designed from the ground up for snappy, visual, real-time writing and planning. Docs, tasks, databases, and version history, in the browser or the app. The Markdown is for your tools, not your team.
Local & private
Local and private, by design.
The mirror lives in a folder on your own machine, so your tools and agents run against it locally, even offline. Everything stays in sync automatically through Thymer's end-to-end encryption, so only you and the people you invite can ever read it.
