It automatically records, transcribes, summarizes, and analyzes business meetings for both individuals and enterprise teams, aiming to turn a one-hour meeting into organized notes with a single click and no complex setup.

After a meeting it produces transcripts, paragraph summaries, key discussion points, and action items with timestamped source quotes, and it can automatically detect the meeting language to handle multilingual conversations. An AI chat feature lets users ask follow-up questions about a meeting beyond the generated insights. The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification.

Siro is an AI coaching and conversation intelligence platform designed specifically for in-person and field sales teams, a segment that traditional call-recording tools built for video meetings do not cover. Reps record their face-to-face customer conversations using Siro's mobile app, and the platform automatically transcribes and analyzes those recordings to surface coaching opportunities, objections, and selling behaviors. A real-time capability called Halftime delivers coaching cues mid-conversation. Siro includes Ask Siro, which lets sales leaders query recorded field conversations in natural language to find patterns in objections, competitive mentions, and rep performance, with answers linked back to specific recordings so managers can review and coach efficiently across many consultations. A self-coaching feature surfaces how stronger reps handled similar situations, giving reps an example to learn from. The platform also drafts follow-ups, flags key deal moments, and syncs data to CRM systems. Siro serves industries with heavy field and in-home selling, such as home improvement, home services, automotive retail, telecom, multifamily housing, and medical aesthetics. Pricing varies by plan. Check the official website for current pricing.
