TesseractTesseract for ChatGPT: your ChatGPT plan, in an app that finishes the job.
Two ways to use them together. In the free Tesseract app, sign in with ChatGPT and the agent runs on your plan, with no charge added on top. In ChatGPT itself, add Tesseract as a connector and ask in your chat for clips, effects and pictures.
Sign in with ChatGPT. Tesseract does the rest.
Tesseract runs Codex, OpenAI’s agent, on your computer and puts the tools around it: a plan you approve, the editors, a terminal and a real browser. Ask in plain words and get back finished presentations, websites, documents and video.
- Download Tesseract. Free for Mac, Windows and Linux; it installs and updates itself.
- Pick OpenAI Codex. On the first-run screen or in Settings. Tesseract installs it for you, or uses the copy already on your computer.
- Sign in. Sign in with ChatGPT, or use an OpenAI API key.
Add Tesseract to ChatGPT. Ask in your chat.
Ask for a clip, a camera move, a long video or one of 250+ effects right in the chat you already use. Tesseract has it made and hands you the finished file.
- In ChatGPT, open Settings → Apps & Connectors → Advanced settings and turn on Developer mode.
- Back in Apps & Connectors, press Create. Name it Tesseract, paste the address, choose OAuth and tick that you trust the app.
- Press Create. Sign in to Tesseract, check that the page names ChatGPT, and press Approve.
- In a chat, pick Tesseract from the tools (+ → More), then ask.
Developer mode is on ChatGPT’s paid plans, and a workspace admin may have to allow custom connectors first. Menu names move between ChatGPT versions. What you ask for is charged to your Tesseract plan, as in the app: your free media is used first, then your allowance or your balance.
