How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Speechmatics when embedding automated transcription into meeting or media platforms matters most. Try them side by side on real calls before deciding — needs vary by team.
Open-source, self-hostable meeting bot API that sends bots into Zoom, Google Meet, and Microsoft Teams to capture recordings and transcripts.
Speech-to-text and voice AI provider offering real-time transcription and live captioning APIs.
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.

Speechmatics is a speech-to-text and voice AI company that provides transcription and captioning technology through APIs, supporting both recorded and real-time audio across many languages.

The platform powers live captioning for events, sports, news, and broadcasts, and its transcription technology can be embedded into other products, including meeting platforms that need automated note-taking and captions. Because Speechmatics is delivered primarily as a developer-facing engine, it serves teams building their own applications as well as media and enterprise customers who need accurate speech recognition at scale. It supports features such as multi-speaker handling and broad language coverage, and the company emphasizes security and compliance certifications. Speechmatics is aimed at developers, product teams, media organizations, and enterprises that need to add accurate transcription, subtitles, or live captions to their own workflows and applications rather than use a packaged consumer note-taker.
