What is Circleback?
Circleback captures, transcribes, and summarizes meetings across online platforms and in-person discussions, automatically assigning action items and exposing conversation context via integrations, webhooks, CLI, and MCP.
Circleback is an AI meeting assistant designed to capture, organize, and automate information from conversations. It handles online meetings via a joining bot or a bot-free desktop app, and in-person meetings through mobile and Apple Watch apps. During meetings, it produces speaker-labeled transcripts with technical-term and accent recognition in over 100 languages, followed by organized notes and automatically identified action items. Beyond basic summaries, the platform functions as a conversation knowledge base. Users can search and ask questions across all previous meetings, connected Gmail or Outlook accounts, and calendar events. Circleback connects with core productivity tools like Notion, Slack, Linear, Asana, HubSpot, Salesforce, and Attio, enabling users to automatically populate CRM records, create issue tracker tickets, and sync tasks. Circleback provides deep developer and AI assistant extensibility. It includes a REST API, webhooks, a command-line interface (CLI), and a Model Context Protocol (MCP) server. The MCP server allows external AI tools—such as Claude, ChatGPT, Cursor, Claude Code, and Raycast—to query meeting notes, search transcripts by keyword or attendee, retrieve action items, and look up company and attendee profiles without manual data copying.
Unlike many meeting notetakers that restrict data to a web portal, Circleback offers extensive developer and agent interfaces—including a native Model Context Protocol (MCP) server, REST API, and CLI—allowing LLMs like Claude, ChatGPT, and Cursor to search transcripts and meeting context directly.
