AI notetaker that records, transcribes and summarizes meetings — bot-free
Capture meetings with a visible notetaker or completely bot-free, so you can record your way and keep participants comfortable.
Get accurate transcripts, concise summaries and extracted to-dos delivered right after each call.
Search and ask questions across your entire meeting history to surface decisions, commitments and patterns.
Notes, insights and follow-ups flow automatically into Slack, Salesforce, HubSpot, Notion, Asana and other tools.

Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
