Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Slipbox when privacy-conscious professionals who cannot use cloud meeting bots 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.

Slipbox is a privacy-first AI meeting companion built for individual professionals and teams who want to capture meetings without sending a bot into the call. Instead of joining a conference as a visible participant, Slipbox runs on your own machine and captures the device's system audio alongside your microphone, then transcribes the conversation on-device in real time. As the meeting progresses it can surface real-time insights and cues, and once the conversation ends it generates AI summaries using customizable templates, tagged notes, and searchable meeting records. Because the core transcription happens locally, audio does not need to leave the device, and the product uses a hybrid model in which optional cloud features can be turned on when needed; users can also bring their own LLM API key or point Slipbox at local models such as Ollama to keep data within their firewall. It works across common communication apps including Zoom, Microsoft Teams, Google Meet, Slack, FaceTime, WhatsApp, Signal, Telegram, Discord, and Webex, and integrates with note tools like Obsidian. Slipbox is available for macOS, Windows, and iPhone, and is suited to consultants, researchers, and privacy-conscious knowledge workers who want a personal meeting record without a meeting bot. Pricing varies by plan. Check the official website for current pricing.
