RevailLab: AI Detector

Spot AI-generated music & text in seconds. Scan audio, paste, photograph

Detect AI-generated music and AI-generated text in seconds. RevailLab is the multi-modal AI detector that catches synthetic audio, ChatGPT-style writing, and OCR'd handwriting — all on your phone, free.

🎵 SCAN MUSIC FOR AI
Hold your phone up to any track playing nearby and tap the mic. RevailLab records 10 seconds, sends it to our hardened detection backend, and returns a verdict in seconds: AI-generated or human-made, with a confidence percentage backed by three independent models.

Or paste an Apple Music link directly. The app fetches the official iTunes preview, runs the same ensemble pipeline, and shows you the breakdown across each model.

📝 SCAN TEXT FOR AI
Paste any passage of writing into the editor and tap Analyze Text. Within seconds you get a verdict from a 2025 transformer-based AI text detector — RAID-benchmark leader, MIT-licensed.

Or photograph printed pages, screenshots, or handwritten notes — RevailLab uses on-device OCR (Apple Vision on iPhone, Google ML Kit on Android) to extract the text, then routes it through the same classifier. Toggle handwriting mode for cursive support.

🔒 PRIVACY-FIRST OCR
Your photos NEVER leave your device. Only the recognised text — and only after you review and edit it — is sent to the backend for analysis. No cloud OCR, no image upload, no hidden tracking.

⚙️ HOW IT WORKS
1. Audio: 10s mic recording or Apple Music URL → ensemble inference → verdict
2. Text: paste, type, or photograph → optional review/edit → verdict
3. Every scan saved locally; tap any history entry to see the full breakdown
4. Daily quota resets every 24h; no credit card, no hidden upsells

📊 BACKED BY SCIENCE
We don't roll our own models. RevailLab uses peer-reviewed, benchmark-leading detectors with transparent licensing:
- Wav2Vec2 deepfake detector (MelodyMachine/Deepfake-audio-detection-V2)
- Music-native AI detector (lofcz/ai-music-detector, MIT, Suno/Udio specialised)
- Spectral fingerprinting against AI-generated frequency artefacts
- DeBERTa-v3-large text detector (desklib/ai-text-detector-v1.01, MIT, RAID benchmark leader)

Every verdict shows the model version that produced it and a per-model breakdown — so you can see why the app reached its decision, not just what it decided.

🔐 PRIVACY COMMITMENT
- Photos and recordings stay on your device
- No advertising IDs collected without consent
- No location tracking
- No background analytics
- Full privacy policy reachable from the app and the store listing
