OpenAI is retiring Prism and will delete its data, pointing users to Codex
Prism, the shared editor for LaTeX projects, is being retired, and the guide says all Prism data will be deleted after shutdown and cannot be recovered. Its migration guide tells users to export all projects as a zip from Settings, then Data Controls, and open the folder in Codex. Codex does not reproduce Prism's shared real-time editor, and project history, inline comments, collaborator permissions and the live Zotero connection don't move with the files.
