STOP GUESSING THE SHAPE OF A REQUEST.

Pick a model. OpenGen UI reads its capabilities live, keeps unsupported fields out, and shows the exact JSON before anything leaves your Mac.

LIVE / 01

THE CATALOG MOVES. THE UI MOVES WITH IT.

Image and video models arrive from OpenRouter at runtime.

FIT / 02

ONLY THE CONTROLS THAT BELONG.

References, frames, ratios, seed, and provider options appear only when supported.

SEE / 03

THE REQUEST, BEFORE THE REQUEST.

Inspect sanitized JSON without leaking large base64 bodies or your key.

02 / 04

THREE CUTS. ONE GENERATION.

  1. 1

    CHOOSE

    Select an image or video model from the live catalog.

  2. 2

    COMPOSE

    Write the prompt and use only the controls that fit.

  3. 3

    GENERATE

    Inspect the payload, send it, and keep long-running video jobs alive.

03 / 04

YOUR KEY STAYS ON YOUR MACHINE.

Your OpenRouter API key is stored in a permission-restricted local file. Requests pass through the native Rust process, and the key is kept out of previews and logs.

IN-APP UPDATES FROM 0.2.0

UPDATE IN APP. KEEP YOUR KEY.

Install 0.2.0 once, then OpenGen UI checks for signed updates whenever it starts.

  1. 01On 0.1.x? Install the latest DMG manually once.
  2. 02New releases appear automatically when the app starts.
  3. 03Choose Update and restart. The package is downloaded and cryptographically verified.
  4. 04The app replaces itself and returns to your workspace.

Your API key stays in ~/.open-gen-ui, outside the app bundle, so updating does not remove it.
