Attachments
The library of every file you have shared into a chat — finding one again, reusing it, and seeing which conversations depend on it.
Every file you attach to a message is kept in Library → Attachments. The point is reuse: a screenshot you shared three conversations ago is findable without remembering which conversation it was.
An attachment is not Knowledge. An attachment is a file that was part of a conversation. Knowledge is a folder the assistant searches across conversations. If you want a document consulted repeatedly, it belongs in a collection.
Finding one
- Search matches file names.
- Images and Documents filter by type.
- Starred only narrows to what you have marked.
- Sort by orders by Updated At, Created At, or name in either direction.
- List view and Grid view switch layout. Grid previews images, which is faster for finding a picture; list shows more per screen, which is faster for finding a filename.
Star anything you reach for repeatedly — starring is the only ordering that survives a library too big to scan.
Using one again
Use Attachment adds the file to the chat you currently have open, without re-uploading it or hunting down the original.
Seeing what depends on a file
View Sources lists the threads that reference this attachment, so you can tell whether a file is still load-bearing before you remove it. A file used in no conversation says so plainly.
This matters because attachments outlive the conversations that introduced them, and a file that looks stray in the library may still be the thing a thread's answers were based on.
Removing them
Delete removes an attachment permanently, and select several to remove them together. References are checked first, so deletion is a decision you make knowing what still points at the file.
Deleting an attachment cannot be undone, and it does not remove the file from the conversations that already used it — those messages keep what was said about it, without the file behind it.
