Stealth Speak
Voice messaging is intimate in ways text isn't — and that intimacy creates a real barrier when anonymity matters. Stealth Speak is a privacy-first voice messaging platform that lets users record and send voice messages without revealing their identity, location, or device metadata. Google AI processes each message to enhance audio clarity — removing noise, normalising volume, and preserving intelligibility — so the message sounds crystal clear even when the sender is protected behind a layer of anonymity.
The Challenge
Standard voice messaging apps either sacrifice privacy (your identity and metadata are always visible) or clarity (anonymised audio often sounds degraded). There's no good option for sending a clear, human-sounding voice message when you want to remain anonymous — whether for candid feedback, sensitive personal messages, or playful anonymous interactions.
The Solution
Stealth Speak separates identity from voice. Each message is tied to a shareable anonymous link — no account, no identifiable metadata stored. The audio is processed through a Google AI enhancement pipeline before delivery: background noise is suppressed, volume is normalised, and speech clarity is improved. The result is a voice message that sounds good and leaves no traceable identity footprint.
Key Features
Zero-Identity Anonymous Messaging
No account required for senders. Recipients generate a shareable private link; senders record and submit a message without any login, no IP logging, and no stored sender metadata.
Google AI Audio Enhancement Pipeline
Every voice message passes through Google AI's speech processing: noise reduction, volume normalisation, and clarity enhancement — so messages sound professional-grade regardless of the recording environment.
Private Shareable Link System
Recipients control their anonymous inbox via a unique, unguessable link. They can share the link publicly or privately, and receive messages from anyone without exposing personal information.
Responsive, Zero-Friction UI
Record directly in the browser with a single click — no app download, no microphone permission prompts beyond the first. ShadCN UI components keep the experience clean and fast across all devices.
