A demonstration and development target for the Lix version control system.
Flashtype is a WYSIWYG markdown editor built on the Lix SDK. It serves as both a showcase for Lix's capabilities and a real-world application that drives the SDK's development—proving that embeddable version control enables powerful features like AI-assisted editing, change proposals, and full document history, all running entirely in the browser.
Flashtype demonstrates key Lix capabilities:
| Lix Feature | How Flashtype Uses It |
|---|---|
| History | Every edit is tracked. See exactly what changed, when, and by whom. |
| Versions (Branches) | AI generates content in isolated versions, letting you review before merging. |
| Diffs | Claude Code-style accept/reject UI shows granular changes inline. |
| Change Proposals | AI proposes edits, humans stay in control of what ships. |
| Single SQLite File | Your documents persist in browser storage as a portable .lix file. |
Visit flashtype.ai to try it in your browser—no installation required.
