# Set Session Title

> Store a conversation's title on the session, so every screen shows it.

Until now the chat generated a title and kept it in the browser's local
storage. Another browser, or a cleared cache, and the conversation was
back to being named by its id -- which is exactly what the evaluation
screen ran into.

Written into ADK's own `state` column with the jsonb merge operator,
which is the very semantics ADK uses itself
(`storage_session.state | state_delta`). The key therefore survives every
later turn, and no ADK write is lost either.

`list_sessions` already returns the state, so nothing has to change on
the read side.
