The open-source alternatives to Fireflies.ai are Meetily, OpenWhispr, Buzz and Vibe. Meetily is the closest in shape: it records a live call from your microphone and system audio, transcribes on your machine with Whisper or Parakeet, and writes a summary with a language model you pick, with a local one recommended. OpenWhispr adds call detection and live speaker labels. Buzz and Vibe cover recordings and files with subtitle and document export. All four are MIT. A team switches when call audio cannot leave the building, or when a per-seat notetaker bill stops making sense.
Fireflies.ai, in the vendor's own words: a service to "transcribe, summarize, search, and analyze all your team conversations", by its own description. fireflies.ai.

Licence, release and star figures read from GitHub on September 16, 2026. Openness labels: The code, and the weights where the project is a model, carry a licence on the OSI approved list. The code is public, and the licence limits what you may do with it. Read the LICENSE file before commercial use. The model weights can be downloaded and run. The training data or code is closed, or the weights carry a restriction the code does not.
A meeting assistant under MIT that records your microphone and system audio together, transcribes live on your machine with Whisper or Parakeet, and summarises with a language model you choose.
Desktop app · macOS (Apple Silicon), Windows x64, Linux (build from source) · Runs on your own machines · Hosted version available from the maintainers
A desktop app under MIT that transcribes and translates audio and video files, YouTube links and a live microphone offline with Whisper, with speaker identification and SRT, VTT and TXT export.

Meetily (MIT) is the closest match for live meetings: it captures mic and system audio together, transcribes locally with Whisper or Parakeet, and summarises with Ollama or a hosted model you choose. OpenWhispr (MIT) auto-detects Zoom, Teams and FaceTime calls and labels speakers on device. Buzz and Vibe (MIT) handle recordings and files.
Not among these four. Each records from the machine you are on. OpenWhispr detects when a Zoom, Teams or FaceTime call starts and can read your Google, Microsoft or Apple calendar, which is the nearest thing to automatic capture on this page.
Yes with Meetily, whose README says no data leaves your computer when you use a local model such as Ollama for the summary. Buzz and Vibe transcribe offline; Vibe's summary uses either the Claude API or a local Ollama model. OpenWhispr runs fully local if you choose local models.
Vibe exports SRT, VTT, TXT, HTML, PDF, JSON and DOCX. Buzz exports TXT, SRT and VTT. Meetily's PDF, DOCX and Markdown exports are listed under its PRO edition. OpenWhispr's README does not list export formats.
OpenWhispr has team spaces and web sharing for signed-in users through its hosted service. Meetily's team features are in its paid PRO edition. Buzz and Vibe are single-user desktop apps.
Running one of these inside your own environment, with your own data and your own security rules, is the kind of work Reveneau does. Read how a forward deployed engagement works.
