Otter.ai holds a narrow edge over Fireflies for transcribing meetings and sharing summaries directly to team channels. Fireflies remains closely matched for teams seeking transcription and automated summaries across chat platforms.
If you mean Slack + Zoom, there are a few strong matches:
Fireflies.ai — likely the closest match. Fireflies joins Zoom meetings, transcribes and summarizes them, then can automatically post meeting notes, action items, and highlights into a chosen Slack channel.
Otter.ai — its Notetaker joins Zoom, records/transcribes meetings and generates summaries; Otter also has a Slack integration that can post meeting summaries to channels.
Zoom itself — Zoom's Slack integration/MCP can retrieve Zoom transcripts and AI summaries inside Slack, though it's more of a Zoom-to-Slack integration than an independent meeting bot.
Best fit: Fireflies.ai if the requirement is specifically “a bot attends the video meeting, transcribes/summarizes it, and automatically posts the recap into our team chat.”
Dedicated Third-Party AI Bots (Work across Zoom, Google Meet, and Teams):
Fireflies.ai : A widely used meeting bot that auto-joins calls, transcribes the conversation, and pushes structured notes and summaries directly to connected collaboration apps and CRMs.
Fellow.app : Functions as an AI meeting assistant that records or imports calls from major video platforms, builds collaborative agendas, and syncs summaries and action items into Slack or task management tools.
Zoom AI Companion : If your video tool is Zoom, the AI Companion can summarize meetings and integrate directly with platforms like Slack to deliver summaries and answer follow-up questions.
To help narrow down the best fit, which specific video conferencing tool (Zoom, Teams, Google Meet) and team chat app (Slack, Teams, Discord) are you using?
You’re looking for an AI meeting assistant that can join video calls, transcribe the conversation, generate a summary with action items, and automatically post the notes into your team messaging app (such as Slack or Microsoft Teams).
The key distinction is finding a tool that automates the entire workflow, rather than one that only records or summarizes meetings.
