While Recall.ai and Attendee both offer a meeting bot API, they have some important differences. Recall.ai offers a smoother developer experience, over 99.9% reliability, and wider coverage of edge cases. We’ve extensively tested Attendee’s features and performance – we’ll dive into what makes Recall.ai stand out.
Recall.ai offers a broad suite of products beyond just a Meeting Bot API, including a Desktop Recording SDK, and an upcoming Mobile Recording SDK. This allows users to record chats that happen on video conferencing platforms, in person, and on the phone, with or without a bot. Attendee, in contrast, is focused specifically on the meeting bot API use case and does not support botless recording methods.
When we tested Attendee, we ran into edge cases that their platform did not account for. For example, we found that Attendee bots would not join if the host was in another meeting. This is a fundamental limitation of their API, and they don’t offer a workaround for this situation. In contrast, Recall.ai allows bots to join and remain in a call even if the host is not present or in another meeting.
When recording videos, Recall.ai captures the raw media streams directly, while Attendee screen-records the video conferencing platform’s UI. This means that Attendee recordings show everything the bot "sees" on screen, including toolbars, participant tiles with names, pop-up notifications, and any modals. Meanwhile, Recall.ai captures clean, high-quality videos with no modals, notifications, or other distracting content.
Suitable for companies in highly regulated industries, Recall.ai is HIPAA, SOC 2, ISO 27001, GDPR and CCPA compliant. Because Attendee’s cloud API solution has no security information or credentials available, it’s a riskier choice for businesses working with customer data, particularly in industries like financial services, legal tech, or healthcare.
Attendee does not have SLAs and offers no other reliability guarantees for its bots. Meanwhile, Recall.ai has a 99.9 uptime SLA, meaning that bots successfully join and record meetings at least 99.9% of the time. This allows startups and enterprises to confidently build and scale products with Recall.ai’s meeting bot API.
Though Attendee claim they support perfect diarization, their API only supports this on Zoom through Zoom RTMS. Recall.ai offers perfect diarization in meetings on Zoom, Microsoft Teams, and Google Meet, accurately assigning speaker names to transcripts even when multiple people talk at once.
Attendee only supports real-time video through Zoom RTMS, and cannot deliver real-time video for platforms other than Zoom. Furthermore, if the meeting host has RTMS disabled, no data will be captured at all – an important consideration if users join meetings outside of their organization. Recall.ai supports real-time video for Zoom, Microsoft Teams, Google Meet, Slack Huddles, and GoTo Meeting, without requiring meeting hosts to enable any additional permissions.
Recall.ai’s unified API works across all major video conferencing platforms, supporting Zoom, Microsoft Teams, Google Meet, Slack Huddles, Webex, GoTo Meeting, and more. Meanwhile, Attendee only supports Zoom, Microsoft Teams, and Google Meet, giving users less flexibility in which meetings they can record.
Unlike Recall.ai, Attendee is open source and supports self-hosting. Though some companies prefer self-hosting because it allows them to keep all of their data in house, using a self-hosted solution requires 45-48% more time to operate. This ends up being a drain on engineering resources, with developers needing to fix bugs themselves and constantly monitor the solution.
Attendee does also offer a cloud-hosted plan, which is much faster to set up than their self-hosted version. However, Attendee’s cloud-hosted solution has less flexibility regarding data storage. Recall.ai lets you choose between storing data in US, EU, or APAC regions and allows you to set custom data retention windows (including zero-day retention). In contrast, even when users request data to be deleted, Attendee will retain meeting transcripts and participant data on their US servers for a minimum of 30 days.
Recall.ai and Attendee have the same pricing structure, each charging $0.50 per recording hour on a Pay As You Go plan and offering volume discounts for higher-usage customers. Although Recall.ai and Attendee cost the same amount, Recall.ai offers more reliability and security while supporting more video conferencing platforms, making it a better choice for startups and enterprises alike.
