What Fireflies.ai does
- A bot (Fred) that joins meetings on the major platforms to record and transcribe.

- Integrations that send notes and action items to CRMs, project tools and Slack.
- Search and a chat assistant over the meeting archive.
What Mainroom does
Mainroom builds AI agents that join Google Meet, Microsoft Teams and Zoom as participants from a calendar invite. In the call an agent speaks when addressed, puts slides and tables on the shared screen, teaches on a whiteboard, runs live browser demos the room can steer, looks things up in your tools, opens anonymous intake for the room, logs decisions and commitments as they are confirmed, and coaches the person who invited it privately. After the call it emails a recap and queues proposed actions for approval.

Which to choose
Fireflies.ai is strong at getting a record out of every meeting and into the tools you already use. Mainroom is for teams that want an agent in the room: it answers, presents, and gathers input during the call, and its writes to your systems wait for a human. If your problem is "nobody reads the notes", an agent that asks for owners and dates while the meeting is still on is the more direct fix.

Frequently asked questions
Can I use Fireflies.ai and Mainroom together?
Yes. A Mainroom agent is one more participant in the meeting and does not need to be the recorder of record. Teams that like their current notetaker keep it.
Does Mainroom produce a transcript and summary too?
Yes. Every call ends with a recap email matched to the agent's role and a ledger of decisions, commitments, open questions and risks that carries to the next meeting with the same people.
Does anything get written to my CRM without approval?
No. Writes to systems of record arrive as proposed actions that the agent's owner approves or discards.
