Echo Chamber: AI Transcription
Voice Recorder & Transcriber
Free · In‑App Purchases
Echo Chamber is the on-device voice transcription app for meetings, lectures, and dictation. Record audio, get a live transcript as you speak, and polish it with AI — all without sending your voice to the cloud.
Built for students and professionals who need accurate transcription, fast.
THE WAY TRANSCRIPTION SHOULD WORK

phone
• Live transcript appears as you speak
• Tap to bookmark a moment without stopping
• Auto-detects pauses, speakers, and topic shifts
BUILT FOR REAL CONVERSATIONS

• Bookmarks survive pauses, backgrounding, and crashes
ORGANIZE, POLISH, EXPORT

• AI-polished readable transcript alongside the raw verbatim
• Search every word across every recording, instantly
• Export to TXT, Markdown, PDF, or DOCX

PRIVACY, BY DEFAULT
Echo Chamber processes everything locally using Apple's on-device speech APIs and our own packaged AI models. No servers, no analytics that watch your content, no third party SDKs that profile you. Audio is encrypted at rest with AES-256-GCM.
REQUIREMENTS
iPhone running iOS 18 or later. Larger language models work best on iPhone 15 Pro or newer.
Subscriptions auto-renew until cancelled in Settings → Apple ID → Subscriptions.
Privacy Policy:

Echo Chamber is now on the Mac. Record meetings from your desktop, and your subscription covers both — buy once, use everywhere.
Also fixed: scrubbing through a recording no longer jumps back to the start when you pause.
Recording, transcription, and search stay free and unlimited, and every recording is still processed on your own device.
