Chat History and Threads

Chat used to be a different conversation on every page. Open a PDF and you got the PDF's chat; open Home and you got another one; your draft stayed behind on whichever page you typed it.

Now there is one chat that follows you. The thread you are in, its history, and whatever you had half-typed all carry across Home, the Chat page, a project, and any piece of content you open. Everything you talked about before is in History.

One Thread, Every Page

Start a conversation anywhere and keep going anywhere:

• Ask something on Home, open a PDF, and the same thread is in front of you — with the PDF now in context.
• A half-written message comes with you. Navigate away mid-sentence and the draft is still there.
• Each message remembers what you had open when you sent it, so "summarise this" means the thing you were looking at at the time, not whatever you opened twenty minutes later.
• Long threads load older messages as you scroll up, so a months-old conversation opens on your most recent messages rather than making you wait for all of it.

Your older per-item chats did not go anywhere. Every conversation you ever had with a specific file, deck, or recording is in History alongside the rest.

Starting a fresh thread

Press New Chat whenever you want a clean slate — a new topic, a different source set, or just a conversation you can find again by subject. There is no limit on how many you keep.

A thread is the right unit for one piece of work: "Q3 board pack", "CPA — audit section", "onboarding deck for the new hires". Several short, well-named threads are much easier to come back to than one enormous one.

Opening History

On desktop, in full-screen chat, press the clock button in the header. Your past conversations open as a panel on the right, beside the conversation you are reading — not over it.

The panel holds:

• Search — type to filter every conversation by title.
• Pinned — the threads you pinned, at the top.
• Recent chats — everything else, most recently used first, loading more as you scroll.

A few things it does that are easy to miss:

• It stays open while you move between chats, so you can read through several in a row.
• It marks the conversation you currently have open, so you never lose your place in the list.
• It remembers whether you left it open or closed and comes back that way next time.

Elsewhere — the sidebar, Home, and the chat panel beside your content — your pinned and recent chats appear as rows you can open directly.

Pinning the Chats You Return To

Pinning is how you keep the two or three threads you are actually living in from sinking under everything else.

Press Pin chat and that thread leads the list everywhere you reopen chat: Home, the sidebar, the Chat page, and the chat panel next to your content. With nothing pinned, those same places show your most recent chats instead.

Pin state belongs to your account, so a thread you pin on a laptop is pinned on your phone.

The Row Menu

Every conversation — in History, in the sidebar, on Home, and on the cards on the Chat page — has a ⋯ menu. On desktop, sidebar chat rows show ⋯ when you hover them. Right-clicking a row opens the same menu.

From it you can:

• Pin chat / Unpin chat
• Rename chat — give it a title you will recognise in a month
• Delete chat

Deleting a Chat

Delete chat removes the conversation from your chat history, the sidebar, Home, and search straight away.

Two things to know before you press it:

• Undo is right there. The confirmation has an Undo, and taking it brings the conversation back as it was.
• A shared link stops working. If you had shared that conversation, its public address stops opening. See Sharing and Collaboration.

Deleting a chat does not delete the sources it used or anything it created. A podcast, deck, or document made in that conversation stays in your library. To remove those too, delete them from your library — where they go to Deleted and can be restored. See Deleting and Restoring Content.

Finding an Old Conversation

Three routes, fastest first:

1. Cmd+K (Ctrl+K on Windows) — search chats alongside every PDF, deck, page, recording, and report you have. See Command Palette.
2. History search — if you are already in chat and remember roughly what the thread was called.
3. The Chat page — pinned threads first, then recent cards.

Each entry shows which AI model answered most recently in that conversation, next to that provider's icon, so a thread you ran on a particular model is easy to spot.

Tips

• Rename a thread the moment it has a subject. "Untitled Conversation" ×12 is the one way to make History useless.
• One thread per piece of work. Context is what makes chat good; a thread that has drifted across four unrelated topics gives worse answers than a fresh one.
• Pin, don't hoard. Pin what you are working on this week and unpin it when you are done.
• Delete rather than let it pile up — but remember a shared link dies with the chat.
