README excerpt
Read full README on GitHub →Your ideas, freshly brewed. Cozy Studio is a free image studio that runs on your own machine. Make images with the subscription you already have (ChatGPT, Grok or Antigravity), pick a style, and keep every result in a folder you can open. No API key is needed for the ChatGPT connection.

What you get
- Styles you can see before you use them. Style packs hold presets for film stocks, painters, anime studios, pixel art, print processes and more, each with sample cards. Essentials, a curated pack of about 100 styles, installs on first start. Mix up to five styles in one image.
- Your ChatGPT plan, no API key. Sign in from Studio Settings and generate with GPT Image models over ChatGPT's own HTTP path. You do not need
OPENAI_API_KEY, and ordinary jobs do not startcodex app-server. - Files you can find. Images go to a
Cozy Studiofolder in your Pictures folder, all in one place, named{timestampUtc}_{generation}_{style}_{prompt}, for example2026-10-03_183042Z_000127_kodak-portra-400_retired-lighthouse-keeper-selling-handmade-kites.png. Sorting by name follows the generation date, time and sequence. - Private by default. The database, thumbnails, logs and sign-in tokens stay in a private app-data folder on your machine. Nothing goes to a hosted library.
- Workflows beyond a prompt box. Remaster, Character Lab, Camera View, Cinematic Storyboard, Timeline Frame, Animation Sequence with GIF export, Sprite Sheet and Sprite Atlas.
- Other providers when you want them. Codex app-server, Grok Imagine, Google Nano Banana and Antigravity sit behind the same backend.
