TextTrellis AI sends selected text, pasted text, or readable page content to the visible ChatGPT composer using the ChatGPT account already signed in to Firefox.
Use the toolbar or context menu to:
Summarize selected text or an entire page
Explain difficult content
Translate text
Correct grammar and spelling
Rewrite text
Draft a reply
Extract key points
Submit a custom instruction
Prompts can be sent automatically or opened in ChatGPT for review and editing first. The extension does not require an API key, access ChatGPT cookies, or call private or undocumented APIs.
TextTrellis AI is an independent extension and is not affiliated with or endorsed by OpenAI. Because it interacts with the visible ChatGPT website, changes to that website may occasionally affect automatic prompt insertion.
