Pick Fireflies.ai if

You’re building around sales, customer success, and product teams who want every meeting transcribed and summarised.. Fireflies joins meetings as a bot and produces searchable transcripts, summaries, and topic tags. CRM integrations to Salesforce, HubSpot, and Notion are the real differentiators against Otter.
