Littlebird

Littlebird is an AI personal assistant that connects across the apps where work already lives — Gmail, Slack, calendar, Notion — and builds standing context from them. Its central claim is the removal of setup: because it already has the thread, the meeting, and the people, you skip pasting backstory into a chat window before you can ask anything useful. It handles meeting notes and pre-meeting prep, runs scheduled routines like a morning briefing or a weekly project update, and surfaces through an overlay called Hummingbird that appears wherever you are working, including on mobile.

The part that matters for a marketing leader is the memory of people and commitments, not the generation. A general assistant can draft; this one is aiming at the layer above that — who is waiting on you, what you promised in the last sync, which decision is still unresolved. For a CMO running several workstreams across agencies, product, and a team, the expensive failure is rarely writing quality. It is the dropped thread and the commitment nobody logged. An assistant with continuous context across mail, chat, and calendar is pointed directly at that.

The trade is access. To be useful it needs broad, persistent read access to your mail, calendar, and messages, which is a real security conversation rather than a checkbox — Littlebird's answer is SOC 2, encryption, granular control over what it retains, and a stated commitment not to train models on your data. Verify that against your own policy before connecting an executive inbox. It is also personal-productivity software rather than a team system, so judge it on hours returned to one person and on whether the context it holds is accurate enough to trust unread.
