How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Kai for Chrome when generating quick meeting summaries and action items without any setup matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

Kai is a Chrome extension that transcribes and summarizes meetings entirely within the browser, running the full pipeline on the user's own device. Built by Morgen, the team behind the Morgen calendar app, it captures audio from any meeting or audio tab in Chrome, including Google Meet, the Zoom web client, and Microsoft Teams, without sending a bot into the call and without requiring an account or sign-up. Recording is triggered with a keyboard shortcut from the meeting tab. Audio capture happens in an offscreen document inside the extension and is transcribed locally using a Whisper speech-to-text model running via WebGPU or WebAssembly, so the audio never leaves the machine. At the end of a call, a local language model produces a clean summary with decisions, topics, and action items, including who is responsible. A side-panel interface lets users follow the transcript live during the meeting, and notes can optionally be emailed to a team in one click, at which point only the final text is shared. This makes Kai well suited to individuals who want fast, private, browser-based meeting notes without installing a desktop app or adding a visible bot, with an initial focus on English-language meetings. Pricing varies by plan. Check the official website for current pricing.
