How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and OpenOats when privately transcribing meetings on a mac without sending audio to the cloud matters most. Try them side by side on real calls before deciding — needs vary by team.

Open-source macOS meeting note-taker that transcribes calls locally and surfaces relevant talking points from your own notes in real time.
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.

OpenOats is an open-source macOS meeting note-taker, created by Yazin Akkawi (the project was previously named OpenGranola before being renamed), that sits alongside your calls and both transcribes the conversation and helps you contribute to it. It captures both sides of a meeting and transcribes audio locally on Apple Silicon so audio never leaves the device, while in real time it searches your own markdown or plain-text knowledge base to surface relevant talking points and things worth saying during the discussion. The application window is hidden from screen sharing by default, which lets it stay private during video calls, and transcripts and session logs are auto-saved locally. OpenOats supports both fully local operation through Ollama and cloud providers such as OpenRouter and Voyage AI, so users can choose between complete offline privacy and hosted models. It is written primarily in Swift, distributed under the MIT license, and actively maintained with very frequent releases. The project documents itself at openoats.com and targets users who want a privacy-respecting, self-hostable alternative to cloud meeting copilots, combining live transcription with a retrieval layer over personal notes rather than only producing an after-the-fact summary. Pricing varies by plan. Check the official website for current pricing.
