Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Polar Notes when converting youtube videos, slides, and pdfs into a study pack matters most. Run both through a week of actual calls to see which suits your workflow.

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.

Polar Notes (PolarNotes AI) is an AI note-taking tool built for students and teachers that converts lectures and course materials into organized study resources. Users can record or upload a lecture, paste a YouTube link, or import slides and PDFs, and the app automatically transcribes audio when needed and analyzes the content to produce summarized notes, key concepts, section headings, and short overviews. From the same source material it can generate a study pack that includes study guides, flashcards, and assessment questions, and results can be exported to Google Docs or PDF with study sets organized in one place. Polar Notes emphasizes privacy and offline access on iOS, keeping notes stored locally on the device unless the user chooses to back them up or share them, which lets students review notes without an internet connection. It also supports multilingual transcription, making it usable for international students and teachers recording in different languages. The tool is delivered as an iOS app with an accompanying web experience and free online tools, and is aimed at learners who want lecture and document content distilled into exam-ready study material rather than verbatim meeting records. Pricing varies by plan. Check the official website for current pricing.
