01 Ultra smooth

1337 @ 120Hz.

GPUI draws leet on your GPU. Search, tabs, panes, and debugger playback keep pace with every frame your display shows.

120Hz

Your display, measured live. Each cell is one frame.

02 Visual debugger

Deterministic.
Frame by frame.

Every test case is recorded once, then replayed like a video. Same input, same frames. Scrub, step, and watch your data structures move.

Every case

All samples and your custom cases are recorded, including Codeforces and CodeChef stdin.

Explain

Ask the agent to mark the step where a failing case first goes wrong.

03 AI, locally

Your agents.
Your problem.

leet runs the coding agents you already have, with the statement, your code, and tests attached. Ask for a nudge, or let Quick Solve take a first pass.

Idiomatic Rust,

No Electron, no web view. A GPUI desktop app and a UI-free practice core, both forbidding unsafe code.
