Duke
Duolingo
Every course, chess and math, around the clock. The streak never breaks.
An autopilot for games
Plays while you sleep.
Games and software on autopilot: Duolingo, Factorio, Game Dev Tycoon, FEZ, Papers, Please, Oxygen Not Included, Pokemon Sapphire and Pikmin 2.
Every game it plays
Each game gets its own bridge: a mod, the save file, the game's own code read before any move. It plays for real. No cheats, no finished saves.
Factorio
Beaten. A rocket launched from a base it built itself, through the game's own API.
Game Dev Tycoon
Running a studio in its own save slot, through a bridge mod.
FEZ
Beaten: all 32 cubes and the Star Gate ending.
Papers, Please
Days 1 to 9 approved, reading every document on the desk.
Oxygen Not Included
Colony 7, every rule read from the game's own code.
Pokemon Sapphire
Playing now as Stitch with Treecko. Live progress below.
Mirage
Our own desert platformer inside Joshua Tree, played from its state lines.
Pikmin 2
Playing now in Dolphin, reading RAM against the decomp. Live progress below.
Duolingo
It reads the answer key
Duolingo draws every exercise from a React component, and that component still holds the answer. Duke walks the component tree from the visible widget up to the challenge, reads the right answer and clicks it. A shape it has never seen gets logged and skipped, never guessed.
Driver
A real browser
One Node runner drives Chromium, signed in as you. Drags and chess moves use a real mouse, because Duolingo ignores synthetic ones.
Chess
Puzzles hand over the moves
A puzzle carries its solution. Bot matches are played by Stockfish, with a bundled engine as the fallback.
Math
Solvers for every unit
Expressions go through math.js. A short list of stubborn levels is still open.
Languages
Every course, unattended
Choice, word bank, typed, cloze, pairs, translate and stories. It walks the whole tree on its own.
Streak guard
The streak survives
If it is evening and no XP has landed, it finishes a language lesson, even through a pause.
Pace
The fastest track wins
It measures XP per hour for every course and moves to the best earner when one finishes or stalls.
Native everywhere
A small app polls the runner over the LAN or the tunnel. Chess is a real animated board. Language and math show the actual prompt and answer. Pause it or switch tracks from the menu, no terminal needed. Reads are open. Pausing and switching need a token.
macOSSwiftUI. Live board, Track menu, pause. The menu bar shows live XP without opening a window.
iOSThe same screen over the LAN or the tunnel, with a home screen widget for XP and streak.
watchOSA glance: XP, track, paused or stuck.
AndroidCompose Multiplatform. Sideloadable APK from CI.
Windows, LinuxCompose Desktop, packaged as an .msi and a .deb.
Terminalduke-tui prints the current state and exits. Check from anywhere over SSH.
A study, not a product
It started as a way to keep a streak alive in a busy week and turned into a study of how much of a gamified app is the client grading itself. Automated play is against Duolingo's terms, and the XP still ranks you against real people. Read it, don't run it.
