Duke plays while you sleep: Duolingo, Factorio, Game Dev Tycoon and FEZ on autopilot. Formerly Surf.
Taken from the repository README

Read the full README ↗Duke plays while you sleep: Duolingo (languages, math, chess), Factorio, Game Dev Tycoon, FEZ, Papers, Please and Oxygen Not Included, around the clock. The games and their status are in games/README.md. Named for Duke Kahanamoku. Formerly Surf, and Cruise before that.

It reads each question's answer out of the page's own React state and clicks it. Math has no answer on the page, so Duke solves those itself. Nothing is guessed. A shape it has never seen gets logged and skipped.
Automating Duolingo is against their terms and can get an account banned. This is a personal study, not a product.

Progress lands in state.json, events in log.jsonl. Port 8737 serves the live state to the status apps and switches course on POST /switch?track=<x>.
The menu bar app lives at ~/Applications/Duke.app, and a LaunchAgent keeps it running. The app starts the runner, and starts it again whenever port 8737 stops answering. Build steps are in CLAUDE.md.
More in docs/ARCHITECTURE.md and the whitepaper. The brand kit is brand/BRAND.md.
