Sessions & Conversation History

A session is one conversation thread. The session dropdown in the chat header
lists them; you can rename, pin, and drag them into the order you want, and that order
follows your account across devices.

The database is the real record. The chat you see is just a viewer onto stored
messages, which is why a session looks identical on a fresh device or after a refresh.
Long sessions open on their most recent messages and page older history in as you
scroll up.

Pruning context — deleting a turn. Every message bubble has a small trash button
(two-click confirm). Deleting removes the entire turn it belongs to — your message
plus every agent step, tool call, and memory write that came from it. Because the
agent rebuilds its view of the conversation from stored turns on every reply, deleting
a turn also removes it from the agent's working memory of the chat — a handy way
to drop expensive or unwanted context the agent keeps re-reading.
