Comparison
Otter is a polished, team-oriented meeting assistant — but your audio is transcribed in its cloud and tied to an account. echo99 keeps recording, transcription, and speaker labels entirely on the Mac in front of you, for free.
Otter.ai is a cloud meeting assistant: it transcribes conversations in real time, writes AI summaries and action items, and builds a searchable, shareable archive across your team. Historically its OtterPilot bot joins your Zoom, Google Meet, and Teams calls; a 2025 desktop app added bot-free local recording as well. It runs on the web, macOS, Windows, iOS, and Android. If you want a cross-platform, team-wide knowledge base with AI chat over your meetings, Otter is one of the most established options — the trade-off is that your audio is processed in its cloud.
| echo99 | Otter.ai | |
|---|---|---|
| How it records | Captures your mic and your Mac's audio output locally — no bot in the call | OtterPilot bot joins Zoom / Meet / Teams by default; a newer desktop app can also record bot-free |
| Transcription | On-device; audio never leaves your Mac; works with Wi-Fi off | Cloud transcription in real time — audio is uploaded to Otter's servers; no offline mode |
| AI notes | On-device notes from the transcript (in development) | A core strength: live summaries, action items, and Otter AI Chat across your meetings — processed in the cloud |
| Raw audio | Keeps mic.wav + system.wav as separate tracks you own | Audio lives in Otter's cloud; MP3 export on paid plans, transcript-only on the free plan |
| Speaker labels | Me + Them-1, Them-2, … plus on-device speaker identification you can name | Cloud diarization with trained speaker identification; untagged voices show as Speaker 1, 2, … |
| Account | None | Account required |
| Price | Free | Free plan about 300 min/month; Pro from $8.33/user/month, Business from $19.99/user/month (billed annually) |
| Platform | macOS 14.4+ | Web, macOS, Windows, iOS, Android, Chrome |
| Sharing & integrations | Plain local files — share them however you already share files | Slack, Salesforce, HubSpot, Notion, calendar auto-join, and shared team workspaces |

You need a cross-platform, team-wide system rather than a solo Mac tool: teammates on Windows or mobile, a bot that auto-joins meetings you can’t attend, live captions during the call, or AI chat, CRM, and Slack integrations over a shared, searchable archive. Otter’s cloud is the point for a distributed team.
Your calls must not be uploaded to anyone’s cloud; you want the actual recordings — clean, separate WAV tracks — not just notes about them; you want speaker-labeled transcripts that work offline and put names to the people you talk to regularly; or you simply don’t want another account and subscription. echo99 is free and on-device, full stop.
