A project is a folder with standing instructions. Create one for a piece of work you keep coming back to, give it instructions once, and every chat inside it starts from them. Projects belong to a signed-in account.
Projects — No projects yet. Create one for a piece of work you keep coming back to.

Projects, before you have created one.

What a project holds

Create a project

1

Sign in

Guests cannot create a project; the chat would have nowhere to live once the tab closes.
2

Open Projects and choose New project

Give it a Name. Instructions are optional and can be changed at any time.
3

Write instructions worth reading before every chat

Who the audience is, house style, units, what to avoid. For example: We sell to mid-market SaaS teams. Prices are in euros. Prefer British spelling.
4

Start chatting inside it

Open the project and start a new chat there, or move an existing thread in with Move to project from the thread header.
New project dialog with Name and optional Instructions fields

New project: a name, and optional instructions that are read before every chat in the project.

Move a chat into a project

Open the thread and choose Move to project in the header. The popover lists your projects — and Remove from project if the thread already belongs to one. A thread belongs to at most one project.
The Move to project popover listing projects and a Remove from project action

Move to project from the thread header.

Files in a project

Add documents to a project so every chat in it can use them. Files come from your Library — attach from the composer or upload from the project — and a chat receives them as attachments, never as a URL you typed. Generated pictures land in Library too. See Library.

Tips

  • Keep instructions short and factual. They are read on every turn, so they cost context on every turn.
  • One project per ongoing piece of work beats one project per topic. The point is continuity.
  • Pin the two or three projects you use daily; the rest stay one click away under Projects.
  • Plans started from a project’s chats stay linked to those chats. See Plans.
Cortex Chat is per account. Another account cannot see your projects, and there is no teammate invite on a thread. Plus and Pro plans list Projects and saved work among their features — check Plans for what your plan includes.
