ChatGPT Plugin Extensions

Plugin makers can now put their apps into ChatGPT's sidebar, side panels, composer, and file viewers, for developers building ChatGPT plugins.

Nine extension types include sidebar apps, panels that open beside the conversation, file viewers and editors, composer mentions, rich forms, and two-way context sync with the model
File viewers let a plugin open, read, and save file types it supports inside ChatGPT
Canva, Figma, and Adobe already have extensions built
A new Plugin Creator in the plugin directory helps prepare submissions, and after approval OpenAI re-checks the plugin's server daily so updates ship without resubmitting
Composer mentions work only in the desktop app, and web extensions for Free and Go users are still coming
