Echo99 发布 macOS 通话记录应用：本地录音、转写与摘要
Echo99 – Record calls. Keep them private
Echo99 发布 macOS 菜单栏应用，可在本机录制、转写并总结 Zoom、Teams、Meet 等通话，无需会议机器人、上传录音或注册账号。麦克风与系统音频分别存为 WAV 文件，支持 25 种语言、跨通话说话人识别、全文回放定位与 Markdown 导出，摘要由本地语言模型生成。
Record, transcribe, and summarize your calls.
Entirely on your Mac - a menu-bar app for Zoom, Teams, Meet, or any call. No meeting bot. No recording uploads. No account required.

Capture with confidence
Record your microphone and the other side as separate WAV files. If your headphones, AirPods, or audio device changes mid-call, echo99 keeps one continuous recording.
Mic + System
Remember people
Name a voice once and echo99 recognizes that person in later calls - so recurring conversations begin with names, not Speaker 1. Voice matching stays on your Mac.
How speaker identification works →
Cross-call identity
Verify every word
Follow the transcript during full-call playback, jump back to the original moment, and export speaker-labelled Markdown when you need it.
How local transcription works →
Audio + transcript
Automatic recording
Enable Auto-record calls once. echo99 starts when another app uses your microphone and stops when the call ends.

One-time toggle
No meeting bot
Nothing joins your call, appears in the participant list, or asks for an invite. Capture stays on the Mac in front of you.
Bot-free capture
Import existing recordings
Drop in an audio or video file and turn it into an on-device transcript with speaker labels, playback, and Markdown export.
Audio + video
Summarize your calls
Turn a transcript into key points, decisions, and action items with a language model running on your Mac. Summarize on demand or automatically after transcription.
On-device AI
Live transcript
Follow what's being said in a floating window while your call records. This optional, on-device preview is separate from the full transcript created after the call.
How live transcription works →
Experimental
From live call to private memory
Capture the conversation, preserve its context,
and return to the exact moment later.
1
Start once - or automatically
Record from the menu bar when you choose, or enable Auto-record calls and let echo99 detect future calls for you.
2
Keep both sides clear
Your microphone and system output are captured separately, which keeps the audio cleaner and makes it easier to tell who is speaking.
3
Return to the original moment
Read the on-device transcript, see familiar speaker names, and use full-call playback to verify what was actually said.
A memory you can inspect
The source audio, context, and transcript stay together as local files.

Built for calls you need to keep
A dependable personal record without turning your calls into somebody else’s data.
Apple silicon & Intel Privacy focused
Private by architecture
Recording, transcription, and speaker matching happen locally. No account, cloud, or meeting bot is required.
People stay recognizable
Voiceprints you control turn anonymous speaker numbers into familiar names across calls.
Evidence stays attached
The transcript remains grounded in the original audio, ready for playback whenever wording matters.
Resilient by design
Switching headphones or AirPods mid-call does not have to break the recording into lost fragments.
Built around people, not meetings
Remember recurring voices across interviews, client calls, research, and everyday conversations.
Portable local records
Keep ordinary WAV, JSON, and Markdown files instead of locking your call history inside a service.
Record your next call on your Mac
No signup and no subscription. echo99 has limited telemetry: the update check at launch sends an anonymous install id and nothing else. Transcription works the same with Wi-Fi off, in 25 languages.
