This is a big update to how you organize and work with Tresor.

Previously, uploaded files were ephemeral — available only during a single request. Now, 

 across your conversation. Upload a contract at the start of a chat, and reference it ten messages later.

Your files remain encrypted and private. Only you can access them.

Projects now go beyond grouping conversations. You can:

Think of a project as a private, focused workspace — shaped around a client, a case, a deal, or a research topic.

Ever hit the point where a conversation gets too long and the AI starts losing context? The new 

 feature solves this. Tresor intelligently compresses earlier parts of the conversation so you can keep going — without losing the thread.

This is especially useful for deep research sessions, ongoing advisory work, or any conversation that naturally runs long.

Both models run inside secure, sealed environments — same privacy guarantees as every other model on Tresor.

 Persistent files are encrypted end-to-end. Project instructions and attachments are visible only to project members. Tresor cannot access any of it.

This release makes Tresor a more powerful workspace for ongoing, complex work. Set up a project, attach your files, and let the AI work within your context.
