Otter.ai has become the standard for in-meeting transcription. Fireflies, Grain, and several other tools follow the same model: record + transcribe, store in cloud, searchable across all your meetings.
For simple voice memos — not meeting transcription, but quick notes to yourself — this is more infrastructure than you need.
Here is the distinction and when each approach makes sense.
Meeting transcription tools (Otter, Fireflies, Grain)
What they do:
- Record audio + generate automatic transcription
- Sync across devices
- Full search across all recordings
- Meeting summaries and action item extraction
Who they are for:
- Teams running standup meetings, 1:1s, client calls
- People who need searchable transcripts
- Workflows where others need access to notes
What they cost:
- Otter.ai: free tier limited to 300 min/month, paid plans from $10/month
- Fireflies: free tier limited, paid from $10/month
Privacy model:
- Your audio and transcripts are stored on their servers
- Enterprise plans add data processing agreements
Voice Notes and Audio Recorder (Firefox extension)
What it does:
- One-click microphone recording inside Firefox
- Saves audio file locally as MP3
- Download to your computer
Who it is for:
- Quick verbal notes during research or reading
- Audio reminders before a meeting starts
- Personal memos that do not need transcription or cloud sync
What it costs:
- Free
Privacy model:
- Audio is captured by Firefox's Web Audio API locally
- Nothing is uploaded to any server
- The file is on your device only
When to use each
Use Otter/Fireflies when:
- You need meeting transcription
- You need search across recordings
- Others need access to the audio
Use Voice Notes for Firefox when:
- You want a quick audio note while already in the browser
- The note is personal and does not need cloud storage
- You want to avoid putting your audio on a third-party server
- You do not need transcription
For quick in-browser voice memos, an extension that runs locally is the right tool. Meeting transcription is a different problem.
