Attendee vs Recall.ai: Meeting Bots Compared

What are meeting recording bots?

A meeting recording bot is a software participant that joins a video call, captures audio and video, and produces a transcript after the meeting ends. According to Otter.ai's 2023 meeting report, professionals attend 25.6 meetings per week on average. Manual note-taking captures roughly 40% of what's said. Automated bots capture 95%+ of spoken content and deliver a searchable transcript within minutes of the meeting ending.

Three tools come up most often for developers: Recall.ai (hosted API, build your own product on top), Attendee (open-source, self-hostable meeting-bot API), and Nylas Notetaker (CLI and API for recording any meeting with one command). Each takes a different approach to the same problem.

How does Recall.ai work?

Recall.ai is a meeting bot infrastructure API designed for companies building meeting-intelligence products. It provides raw recording, transcription, and real-time streaming APIs. Recall.ai supports Zoom, Google Meet, Microsoft Teams, Webex, and GoToMeeting — 5 platforms covering over 95% of enterprise video calls. Pricing is usage-based per bot-minute according to their published pricing page.

The target audience is B2B SaaS companies that need to embed meeting recording into their own product. Recall.ai handles the bot infrastructure (joining, recording, transcribing) so product teams don't build it from scratch. Over 100 companies use it according to their homepage. The trade-off: you need engineering resources to integrate their REST API, handle webhooks, and build your UI on top.

How does Attendee work?

Attendee is an open-source API for building meeting bots — a developer tool, not an end-user notetaker app. According to its documentation, you self-host it (Django, Postgres, Redis) or run the hosted enterprise edition, then call a REST API to send bots into Zoom, Google Meet, and Microsoft Teams — the same three platforms that cover most enterprise video calls.

Attendee describes itself as "the open source API for building meeting bots" and ships its full source at github.com/attendee-labs/attendee. Because the stack is self-hostable, teams that must keep meeting recordings and transcripts on their own infrastructure can run the entire pipeline themselves. The trade-off mirrors any self-hosted service: you operate, scale, and patch the bot infrastructure instead of consuming it as a managed API.

How does Nylas Notetaker work?

Nylas Notetaker sends a bot to any Zoom, Google Meet, or Microsoft Teams meeting using a single CLI command. The bot records audio and video, generates a transcript, and returns the media as downloadable URLs in JSON format. Setup takes under 2 minutes — install the CLI, configure your API key, and run nylas notetaker create. No SDK integration, no webhook infrastructure, no separate dashboard.

The nylas notetaker create command accepts a meeting URL and an optional join time. The CLI handles authentication, bot lifecycle, and media retrieval through the same tool you already use for email and calendar. Transcripts come back as structured JSON that you can pipe into any downstream tool — grep, jq, a database, or an LLM for summarization.

# Record a Zoom call — bot joins immediately
nylas notetaker create --meeting-link "https://zoom.us/j/123456789"

# Schedule a bot for tomorrow's standup
nylas notetaker create \
  --meeting-link "https://meet.google.com/abc-defg-hij" \
  --join-time "tomorrow 9am" \
  --bot-name "Standup Recorder"

# Get the transcript and recording URL
nylas notetaker media ntk_abc123def456 --json

How do Attendee, Recall.ai, and Nylas compare?

All three tools are developer-facing, but they differ in how you run them. Recall.ai is a hosted, closed-source API. Attendee is an open-source API you self-host. Nylas Notetaker is a managed API plus a CLI that bundles meeting recording with email and calendar in one tool. The comparison table below covers the 8 dimensions that matter most when choosing between them.

When should you use each tool?

Choose Recall.ai when you're building a meeting-intelligence product for end users and need infrastructure-level control over bot behavior, real-time audio streaming, and custom transcription models. The integration takes days to weeks but gives you full programmatic control over the recording lifecycle.

Choose Attendee when you want an open-source meeting-bot API you can self-host — for example, when compliance or data-residency rules require meeting recordings to stay on your own infrastructure. You trade the convenience of a managed service for full control over the bot stack, and you take on running Postgres, Redis, and the bot workers yourself.

Choose Nylas Notetaker when you need meeting recordings as part of a larger automation workflow — piping transcripts to an LLM, sending summaries via email, archiving meeting data alongside calendar and contact records. The CLI gives you JSON output in the same tool you already use for nylas email send and nylas calendar events-list. A 45-minute meeting produces a transcript in under 3 minutes after the call ends.

# Record a meeting and download the transcript
NOTETAKER_ID=$(nylas notetaker create \
  --meeting-link "https://zoom.us/j/123456789" \
  --json | jq -r '.id')

# Later: fetch transcript URL and download it
TRANSCRIPT_URL=$(nylas notetaker media "$NOTETAKER_ID" --json | jq -r '.transcript.url')
curl -sL "$TRANSCRIPT_URL" > transcript.txt

How do you combine meeting data with email?

Meeting recordings become more valuable when paired with the email thread that scheduled them. The Nylas CLI connects both data sources through a single authentication. After a meeting ends, you can send the transcript summary to all attendees, attach it to the calendar event as a note, or store it alongside the email thread for context. This workflow takes 4 commands and no external integrations.

Recall.ai and Attendee focus on the meeting-bot layer and don't bundle email or calendar. With either one you'd build a separate email integration (SendGrid, SES, or Graph API) and wire it to the transcript output yourself. The Nylas CLI handles meetings, email, and calendar as a single tool — the meeting notes automation guide walks through the full workflow step by step.

# Download transcript and email it to attendees
TRANSCRIPT_URL=$(nylas notetaker media "$NOTETAKER_ID" --json | jq -r '.transcript.url')
TRANSCRIPT=$(curl -sL "$TRANSCRIPT_URL")

nylas email send \
  --to "team@company.com" \
  --subject "Meeting Notes: Sprint Planning" \
  --body "$TRANSCRIPT"
