Tool-calling agent that can read, click, scroll, and navigate live pages on your behalf — with an animated cursor + tab-lock banner so you always see what it's doing Long-term memory SQLite + FTS5 across episodic and semantic stores — Dao remembers what you've worked on, not just what's in the current tab Proactive suggestions triggered by navigation — Dao notices when a page matches a scenario you've taught it, then offers to act Skill system — extend the agent with reusable skills; manage them from chrome://dao-agent/skills Ask AI from the command bar Cmd+L — turn any thought into an agent task without leaving the keyboard Page → Markdown capture and share-card generation baked into the chat surface Learn more at dao.msgbyte.com/agent https://dao.msgbyte.com/agent .
