Search
Find conversations from the sidebar and understand how search activity and memory-assisted context appear in replies.
Find a conversation
Search chats is at the top of the Chat sidebar. Desktop also exposes it from Edit and with Ctrl/Cmd+K. Mobile opens a Search chats dialog from the drawer; its field is labeled Search chats and messages. Results update while the query is typed, and selecting a result opens the conversation.
On the web and desktop, the sidebar search matches unarchived chat titles and shows the most recent matches. It is useful for a known project or conversation name, but it does not search every line of an archived transcript. Archived conversations remain available from Settings > Archives. Mobile can also match the title and the message preview or loaded task data available to that device, so its result set can be broader without being a guarantee of full transcript indexing.
Each result keeps the conversation title visible and may show its project and pin state. No matching result shows a short Try another title or phrase prompt. Opening a result restores the normal Chat view, where the full transcript and its message actions remain available.
Search activity in a reply
The assistant can use web search when the selected model and conversation allow it. During the turn, the transcript shows a Searching activity row. The completed answer can include source pills that open the supporting pages, keeping search activity and citations next to the answer that used them.
Search with memory
Chat History Memory is a separate setting in Memory. When enabled, finished text turns can be indexed for relevant context in a future reply. It does not add a full-transcript search box to the sidebar, and turning it off does not remove chats. Wipe in Settings > Memory removes those indexed chunks while keeping the conversations themselves.
For a stable grouping, place conversations in a project and search its name. For durable facts, review Memory rather than relying on a title or preview match.
