Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and timeOS when cross-tool follow-ups matters most. Try them side by side on real calls before deciding — needs vary by team.

AI that auto-joins calls and delivers notes plus daily briefings
Attendee is an open-source REST API, developed by Attendee Labs, that abstracts the engineering work of building meeting bots into a single developer-friendly interface. Instead of maintaining separate bot stacks for each video platform, developers send one API request and Attendee dispatches a bot that joins a Zoom, Google Meet, or Microsoft Teams call, then returns recordings, transcripts, and real-time media streams. It is built on widely used, battle-tested technologies such as Django, PostgreSQL, and Redis, and is designed to run from a single Docker image so teams can self-host it on their own infrastructure for data residency, compliance, and cost control. The project documents real-time transcription, webhooks, calendar integration, scheduled meetings, and websocket audio input/output. Because it is open source and self-hosted, organizations in regulated industries can keep meeting audio and transcripts inside their own environment rather than routing them through a third-party vendor. The repository is actively maintained with frequent releases, and the project markets itself as a lower-cost alternative to closed-source meeting-bot platforms for developers who want to embed meeting capture and transcription into their own applications. Pricing varies by plan. Check the official website for current pricing.

timeOS is an AI meeting assistant that automatically captures, transcribes, and summarizes meetings across major conferencing platforms, then routes the resulting notes and action items into the tools teams already use. It positions itself as an AI layer over your workday: beyond producing summaries, it aims to handle follow-through by syncing notes to documents, task managers, and other apps so nothing falls through the cracks after a call. It supports multiple languages and can generate concise recaps that are easy to share with attendees and stakeholders. Because it focuses on automating the post-meeting workflow, timeOS appeals to busy professionals and teams who want notes to flow automatically into their systems rather than copying them by hand. It is typically used for recurring meetings, cross-tool follow-ups, and keeping a searchable record of decisions, with an emphasis on reducing the manual admin that surrounds meetings. Platforms: Zoom / Google Meet / Microsoft Teams. Integrations: Zoom, Google Meet, Microsoft Teams, Notion, Slack. Pricing varies by plan. Check the official website for current pricing.
