Chat
An AI conversation attached to an element of your Stream, not a separate app.
Chat is a detail view, not a mode: you open it from an element (or from the input field), talk to the AI about that content, and the conversation is saved back into the Stream as its own element.
Starting a chat
- Type a question in the input field and press ⌘ ⏎.
- Or select an element and choose Ask AI (⇧ ⌘ I) – the element becomes the context.
- Multi-select works too: Ask AI about several elements at once.
In the conversation
- Responses stream in; the chat scrolls like a normal messenger.
- Attachments (⇧ ⌘ A): attach images, PDFs, text, or source files from a file picker, or just drag a file onto the chat, or paste an image directly from the clipboard. Images are understood by vision-capable models; text is extracted from attached files where possible.
- Token usage: when the provider reports it, a small badge shows prompt/completion/total tokens for the conversation.
- Similar items: an accordion at the bottom of the chat surfaces other saved elements that are semantically close to the conversation – see Semantic search.
- The provider and model come from Settings → AI – chat has no per-conversation model switcher. Chats get short titles automatically, editable with ⇧ ⌘ E.
- History persists – a chat is an element in the Stream, filter with the Chats chip, favorite it, export it, delete it (⌘ ⌫).
Message actions
Hover a message to reveal its actions:
- Copy: copy that message’s text, on any message.
- Regenerate: re-run the AI’s last reply from scratch (only shown on the last assistant message).
- Retry: shown instead of Regenerate when the last reply was cancelled or failed mid-stream; picks the request back up.
- Delete: remove a single message from the conversation.
- Stop: while a response is streaming, stop it early (also bound to Esc).
Attachment chips can be removed individually before sending, and opened afterwards (images in Preview, other files in their default app).
