About the founder
Hi — I’m Mathias. I built RewriteBar because I wanted an AI writing assistant that lives in the macOS menu bar and fits into real workflows (email, docs, tickets, and everything in-between).
- Pragmatic focus: speed, reliability, and actions that feel like native macOS tools.
- Built in public-ish: ship improvements fast, listen to feedback, iterate.
- Made for people who write all day: founders, PMs, support, and developers.
