What our research says

Fireflies.ai

Unlimited transcription on the free tier is the hook and it is genuinely unlimited — the meter sits on storage and AI credits, which is where any team of real size ends up on a paid seat.

Pros

  • Transcription minutes are unlimited on every tier, including Free
  • API access is not paywalled — it starts on the free plan
  • Pro at $10/seat undercuts most rival meeting assistants
  • Storage becomes unlimited from the $19 Business tier

Cons

  • Monthly billing is about 1.8x the annual rate on Pro and 1.5x on Business
  • AI credits, not transcription, are the real ration — 20 a month on both Free and Pro
  • Free storage is 400 minutes for the entire team, not per person
  • Enterprise is annual-only at $39/seat

Sembly AI

Worth the premium when you need meetings turned into structured commitments — tasks, risks, decisions — rather than a searchable transcript. If a transcript plus a summary paragraph is all you want, this is priced well above what you need.

Pros

  • Extracts risks, decisions and tasks as separate items rather than one summary blob
  • Multi-meeting chat, AI-generated documents and insights from the Pro tier upward
  • Captures Zoom, Teams, Meet and Webex rather than a single platform
  • MCP access on Pro and MAX lets external agent clients reach the meeting data

Cons

  • No standing free tier — every plan's free option is a time-limited trial
  • Single-user Basic at $17/month sits above several competitors' entry price
  • The differentiating features all start at Pro, so Basic is a weak comparison point
  • No public developer API; the /api path resolves to a sales demo form

Which one fits

Choose Fireflies.ai if you need

  • PMOs and consultancies tracking commitments across dozens of calls

  • Regulated environments needing HIPAA handling, custom SSO and audit logs
