OpenAI is shutting down Prism, the free LaTeX workspace it launched for scientists in January. A notice now sits at the top of the original announcement: “Prism will shut down on January 1, 2027.” Users began posting the shutdown email on X on October 30, 2026, and a community forum thread flagged it the same afternoon.
The part that matters most is in the migration guide: “After shutdown, all Prism-related data will be deleted.” Researchers with papers in progress have 63 days from the email to export them, and some of what a shared project holds will not leave with the files.
OpenAI will shut down Prism, its free LaTeX workspace for scientists, on January 1, 2027.
After shutdown, all Prism-related data will be deleted and cannot be recovered, per OpenAI’s migration guide.
Users can export every project as a zip from Settings, Data Controls, and single projects from the title menu.
Project history, inline comments, collaborator permissions and the live Zotero connection do not move with the export.
OpenAI points users to Codex for the LaTeX source, though it does not reproduce Prism’s shared real-time editor.
§ 01What OpenAI announced
Prism launched on January 27, 2026 as “a free, AI-native workspace for scientists to write and collaborate on research”, available to anyone with a personal ChatGPT account. It will have run for 339 days when it closes. The notice asks users to “Export your Prism projects before the shutdown date to keep a copy of your files.”
OpenAI’s guide points users to Codex as the place to keep working on the LaTeX source. It is plain about the gap: Codex “does not reproduce Prism’s shared real-time editor”, and most multi-file projects will need a local TeX toolchain. OpenAI has not published a reason for the shutdown.
§ 02What survives the export, and what does not
The guide gives one path out: Settings, then Data Controls, then Export all projects (zip), then Download zip. Single projects export from the project title menu. The zip holds the project files; the guide lists what stays behind.
| Part of a Prism project | After export |
|---|---|
| LaTeX source and project files | Kept, in the zip |
| PDFs of finished papers | Download them yourself |
| Project history | Lost |
| Inline comments | Lost |
| Collaborator permissions | Lost |
| Live Zotero connection | Lost |
| Prism chats | Some exports include JSON files for reference only |
For a group paper, the comments and history are often where the decisions live. Anyone who needs them should copy the threads into the document, or a shared doc, before January 1.
§ 03What to do before January 1
- Export every project now. The zip is the only copy that survives; OpenAI says deleted data “cannot be recovered.”
- Download PDFs of anything finished. The guide suggests it, and a PDF needs no toolchain to open.
- Move comment threads by hand. Nothing carries them over, so paste the ones that matter into the source or a notes file.
- Check that the source builds outside Prism. Install a local TeX toolchain, or use another LaTeX editor, before the deadline rather than after.
§ 04What is confirmed, and what is not
| Claim | Status |
|---|---|
| Prism shuts down January 1, 2027 | Confirmed: OpenAI’s announcement page |
| All Prism data is deleted after shutdown | Confirmed: the migration guide |
| History, comments and permissions do not export | Confirmed: the migration guide |
| Codex replaces the shared editor | No: the guide says it does not |
| A reason for the shutdown | Not given by OpenAI |
§ 05Where CellCog stands
Our conflict, declared: CellCog sells AI employees, and does not run on Prism. The shutdown is a reminder of a rule we build around: the files an AI employee makes on CellCog live in its own workspace and your Drive, where you can download them at any time.
Q1What was Prism?
A free, AI-native workspace for scientists to write and collaborate on research in LaTeX, launched by OpenAI on January 27, 2026.
Q2How do I export my Prism projects?
Open Settings, then Data Controls, then Export all projects (zip), then Download zip. Single projects export from the project title menu.
Q3Can deleted Prism data be recovered?
No. OpenAI’s migration guide says that once the data is deleted, it cannot be recovered.
Q4Is Codex a full replacement for Prism?
Not fully. Codex can work on the exported LaTeX files, but OpenAI says it does not reproduce Prism’s shared real-time editor.
Q5Why is OpenAI shutting Prism down?
OpenAI has not published a reason. The notice gives only the date and asks users to export their projects.
