AI Notetakers: Otter, Fireflies, Granola, Fathom, Read AI, Gumdrop
Six AI notetakers are quietly rewiring the meeting: Otter and Fireflies chase scale, Granola bets on augmenting your own notes without a bot in the room, Fathom wins on a generous free tier, Read AI reads the room's mood, and Gumdrop (from Kayak co-founder Paul English) prepares you before you ever say hello. Together they map an entire category racing from novelty to default.
Tana
Tana is an AI-native workspace that turns messy notes, meetings and voice memos into structured, queryable knowledge. Its signature feature, Supertags, lets any bullet point become a database record with defined fields, so notes double as a living knowledge graph that AI agents can read, summarize and act on. Founded in 2021 by ex-Googlers and productivity builders and based in Palo Alto with an engineering hub in Oslo, Tana raised a $14M Series A in February 2025 (led by Tola Capital), reaching $25M total funding after emerging from a stealth beta with a 160,000+ person waitlist.
