Can I open-source Cotypist?
KINDA · partial or early alternativesKinda. Stirling PDF and Flameshot cover the core of Cotypist, but they're early or partial — expect gaps like Coverage: your build will work in native text fields and fail or misbehave in Electron apps, browsers, and terminals and Latency polish: suggestions that arrive after you already typed the words are worse than nothing.
Because a text predictor that works in nine apps and glitches in the tenth is a text predictor you turn off. The value here is invisible reliability across an entire OS, which means quietly handling every app that draws its own caret, every accessibility API quirk, and every macOS release that changes the rules. That is maintenance work, not a build, and it is worth a small license fee to hand off.
