Otter.ai vs Circleback

Otter.ai

Web, macOS, Windows, iOS, and Android

Broad app coverage makes Otter easy to use in virtual or room conversations. The desktop app now supports configurable automatic recording for detected calls. Feature parity and allowances differ between in-app and imported usage.

Circleback

Web, macOS, Windows, iOS, Android, and Apple Watch

macOS and Windows apps capture online meetings without a bot, including system audio and video, with recording from the detected-meeting prompt. The iOS and Android apps record in-person conversations and include Assistant. Apple Watch records from your wrist without the iPhone nearby. Every app sends recordings into the same Circleback meeting system.

Otter.ai

Strong mobile live transcription

iOS and Android support in-person recording with live text. Otter separates voices after processing and can learn previously tagged speakers, but new or uncertain voices remain Speaker 1 or Unknown until tagged. Live platform-name labels are a separate Notetaker behavior, strongest on Zoom.

Circleback

Phone, desktop, or Watch—with speaker labels

Record in-person conversations from iOS, Android, macOS, Windows, or Apple Watch. For quick capture, tap your phone’s Lock Screen widget or Apple Watch complication, or press and hold your configured iPhone Action button. No separate recorder is needed. Recordings get the same speaker labels, notes, assigned action items, search, sharing, and automations as online meetings. Phone calls use an existing call recording imported into Circleback.

Otter.ai

Audio playback broadly; video replay on Enterprise

Audio is synchronized to text on ordinary plans. Video replay requires Enterprise and currently applies to supported Zoom and Google Meet recordings rather than every capture path.

Circleback

Optional recordings with playback, downloads, and clips

Every capture route can keep the source recording with the meeting. Play it beside the transcript, download it, link to a moment, or make a clip. If you only want notes and the speaker-labeled transcript, turn recording storage off.

Otter.ai

Live transcript, search, and automatically assigned action items

Otter automatically detects and assigns action items, links generated work back to transcript evidence, and gives each user a cross-meeting list with edit, reassign, and completion controls. That list only shows work assigned to the signed-in person, rather than a workspace-wide manager view. Allowances and advanced custom workflows vary by plan.

Circleback

Detailed standalone notes, assigned action items, and cited search

Circleback’s notes are designed to give someone who missed the meeting its context, decisions, and next steps. It automatically creates action items and assigns them when the conversation makes the owner clear. One workspace-wide list lets teams filter and complete tasks across meetings. Custom insights extract the fields a team needs, while Assistant searches meetings and connected email with citations.

Otter.ai

Cross-meeting search and chat

Otter can answer across conversations, but does not emphasize full relationship pages combining meetings, email, calendar, people, companies, and future events.

Circleback

Meeting and email history for each person and company

Person and company pages combine rolling summaries, relationship timelines, emails, meetings, attendees, and upcoming events. Search and Assistant work across that context, so a conversation stays useful to the next person and the next team.

Otter.ai

User auto-share and Enterprise workspace defaults

Individuals can auto-share by calendar audience and use channels. Enterprise admins can choose the options members see and set a default, but ordinary audience defaults are not fully locked; admins can only force privacy by leaving “Don’t share” as the sole option. External auto-share channels are also Enterprise-only.

Circleback

Conditional automatic sharing with workspace safeguards

Automations can share matching meetings with specific people, teams, or the whole workspace based on titles, participants, invitee emails or domains, tags, and combined conditions. Admins can set or enforce default sharing access while members retain explicit controls for private or sensitive conversations.

Otter.ai

Meeting agents and custom workflows, with plan differences

Otter automatically detects and assigns action items, tracks each person’s work across meetings, can create Jira issues with assignees and due dates, and uses custom workflows, Zapier, and AI Chat actions for role-specific output and downstream work. The personal action view does not give a manager one board for every assignee, and connector or workflow eligibility varies by plan.

Circleback

Conditional sharing, CRM updates, and task creation

Run actions when meetings match conditions, extract the fields each team cares about, share notes, and route the result into the system where work happens. Sales can update the CRM; product and research can collect themes; engineering can open assigned issues in Linear or another tracker; recruiting and customer teams can route structured follow-up. Automations also post to Slack, call webhooks, and re-run against older meetings.

Meeting platforms, CRM, Zapier, Slack, Jira, work-app connectors, and Enterprise exports

Paid plans connect Salesforce, HubSpot, and Zapier. AI Chat’s Advanced mode can read and act in Gmail, Google Drive, Notion, and Jira, with Salesforce context available separately. Slack can post summaries and action notifications, while Enterprise supports account-manager-enabled SharePoint and automatic Drive exports. Availability and setup vary substantially by plan.

Search other apps, then do the work there

Circleback Assistant can look up context and take actions in tools such as Linear, Notion, Asana, HubSpot, PostHog, Attio, Ashby, Intercom, and Plain. Automations can create Linear issues from assigned meeting action items, write action items to monday.com, and send outcomes to Slack, Salesforce, Zoho, and more. Connect additional tools through Zapier, Make, webhooks, or custom MCP servers.

MCP broadly; API and webhooks on Enterprise

MCP is listed even on Basic and can access meetings captured by or shared with the authenticated user. It currently has no public API-key setup for arbitrary AI applications. The public API and webhooks require Enterprise and account-manager enablement.

Circleback

The same complete meeting data for people and AI agents

Circleback is built for people and AI agents. The complete meeting record a person can access—its full speaker-labeled transcript, recording, notes, action items, metadata, attendees, and related people and companies—is also available programmatically through the public API, MCP, and CLI. The API also supports action-item updates. MCP and CLI add search and retrieval across meetings, transcripts, action items, calendars, email, people, companies, and tags, and can update meetings and tags, share meetings, and create, update, or delete action items. Connect ChatGPT or Claude, build internal tools, or receive meeting data by webhook.

Business administration; advanced security on Enterprise

Business adds centralized features and bulk export. Enterprise adds SSO, SCIM, API access, video replay, granular retention, no-training by default, and HIPAA options. Several advanced controls—including retention and automatic Drive export—require account-manager setup.

Security, privacy, and workspace controls

Customer data is encrypted at rest and in transit and never used to train models. Circleback is SOC 2 Type II, certified under the EU-U.S. Data Privacy Framework, supports GDPR obligations, and is HIPAA-compliant with BAAs available. The security portal includes compliance materials and an external infrastructure pentest report. Available controls include single sign-on (SAML or OIDC) and SCIM provisioning, configurable data retention and recording storage, enforced workspace and sharing settings, teams and roles, domain and API key access controls, centralized billing, usage reporting, and free viewer seats.

Six transcription languages, two still in beta

Otter transcribes English, Spanish, French, German, Japanese, and spoken Mandarin with Simplified Chinese output. German and Chinese are beta. It normally handles one language per conversation; French can auto-switch with English, and other mixed-language pairs are not supported.

100+ transcription languages

Users can choose from more than 100 meeting languages and separately control the output language used for generated notes.
