The Best Open-Source Granola Alternative in 2026

Granola popularised the idea of an AI notepad that quietly listens to your meeting and turns your sparse notes into a polished summary. It's well-designed — but it's closed source, macOS-first, and it processes your meeting audio in its cloud. For a lot of people and most companies, that last point is a dealbreaker.

What an open-source Granola alternative should do

• •Transcribe meetings accurately, including the other participants — not just you
• •Keep audio on your device so sensitive conversations never hit a third-party server
• •Work on any OS, not just macOS
• •Be free for individuals, with a clear, non-predatory upgrade path for teams
• •Be genuinely open source so you can audit or self-host it

How ParleyNotes compares

ParleyNotes runs OpenAI's Whisper model directly in your browser using WebGPU or WebAssembly. The audio is captured from your meeting tab and microphone and transcribed locally — nothing is uploaded. It's MIT-licensed, so you can read the code, fork it, or run it inside your own network. And because the compute happens on your machine, it's free for individuals with no minute caps.

When Granola still makes sense

If you live entirely in macOS, want a native menu-bar app, and you're comfortable with cloud processing, Granola is polished and worth the subscription. If you care about privacy, cross-platform support, or open source — or you just don't want to pay per seat — ParleyNotes is the better fit.
