## Circleback

Circleback is built around the idea that a meeting should keep producing value after it ends. It joins or records your calls — via a bot or a bot-free desktop app for macOS and Windows — transcribes each speaker by name, and automatically generates organized notes, decisions, and assigned action items. Everything it captures becomes searchable, so you can ask questions and get answers drawn from every conversation your team has had.

The product goes beyond note-taking with a layer of automations and integrations. After a meeting it can update HubSpot or Salesforce records, create Linear issues, update Notion pages and Asana tasks, log activity in Attio, or send notes to Slack. A universal task list aggregates action items from all meetings, and an API, webhooks, MCP endpoint, and CLI let developers feed meeting context into AI agents and custom workflows.

Circleback is backed by Y Combinator and used by teams at a wide range of companies. It supports in-person recording, importing past audio or video, and capturing what is shared on screen so slides and dashboards appear in your notes. It offers a free tier plus paid plans, with pricing listed on its site.

**Pricing & Plans:** Free to start, with paid plans for higher usage and advanced features. A free trial and tier are available; see circleback.ai/pricing for current plan details.

**Strengths:** Highly accurate notes and action items praised by users across sales and product roles; Very broad integration coverage, from CRMs to issue trackers and Slack; Bot-free desktop app option plus in-person recording support; Supports 100+ languages with named speaker identification

**Limitations:** Advanced automation and higher usage require paid plans; The breadth of integrations can take time to configure well; Very long meetings and heavy usage consume plan minutes quickly

## Sonnet AI

Sonnet AI is built around a simple premise: the value of a meeting should outlast the call. It runs as a Windows desktop app that listens to your device audio, so instead of a bot joining the room, Sonnet stays invisible to other participants. That design choice is why it works on Zoom, Google Meet, Microsoft Teams, Slack, Discord and other platforms without needing a native integration for each one.

The assistant covers the full arc of a conversation. Before the call you get AI-generated profiles of the participants so you know who you are meeting. During the call Sonnet transcribes in real time while you focus on the discussion. Afterwards it produces customisable notes, extracts action items with assignees and deadlines, updates CRM entries, and files everything in a searchable archive.

Sonnet also leans into workflow flexibility. A template gallery covers domain-specific formats for sales, legal, medical and recruiting conversations, and notes can be shaped with tables, concept maps and tailored structures. Meeting reminders help you arrive prepared, and a companion mobile app is listed as in development. The free tier includes five notes per month with no credit card, and the company reports all systems operational.

**Pricing & Plans:** Freemium. The free tier includes 5 notes per month with no credit card required. Paid plans are billed monthly or annually, with the annual option offering a discount; enterprise and higher-volume arrangements are handled via contact. Exact tier prices are shown on the Sonnet pricing page.

- **No meeting bot required:** Sonnet records and transcribes without joining the call as a bot, so no unattributed participant shows up in the meeting.
- **Custom notes and template gallery:** Format notes with tables, concept maps and purpose-built layouts, or choose from dozens of domain templates for sales, legal, medical and recruiting conversations.
- **Automatic action items:** Tasks are pulled out of the transcript with owners and due dates, so follow-ups do not depend on someone rereading the recording.
- **Relationship tracking and auto-updating CRM:** Sonnet builds context-rich profiles of everyone you meet and can push notes into your CRM automatically.
- **Works across every major platform:** Because it captures device audio, Sonnet works with Zoom, Google Meet, Teams, Slack, Discord and other platforms without per-app integrations.

**Strengths:** No attendee bot, so meetings stay anonymous on the participant list; Works with Zoom, Meet, Teams, Slack and Discord without per-platform integrations; Notes are searchable, making old conversations reusable reference material; Domain templates plus automatic action items and CRM updates cut manual follow-up
