### Why Sonar?
Most AI voice tools charge per character and store your data on their servers. Sonar is different. It runs 100% on your local hardware.
100% Private: Your voice clones and documents never leave your Mac.
No Subscriptions: No monthly credits, no character limits, no hidden fees.
Offline First: Generate high-fidelity speech in a plane, a bunker, or anywhere without Wi-Fi.
Silicon Optimized: Deeply integrated with Apple Silicon for lightning-fast, zero-latency generation.
### Core Features
Pro Voice Cloning: Create a digital twin of any voice in seconds. Perfect for consistent narration and personalized content creation.
The Ultimate Reader: Transform PDFs and EPUBs into immersive audiobooks. Sonar uses advanced neural models to provide natural, human-like expression.
Studio-Grade Export: Export your narrations as lossless WAV files. Ready to drop into Final Cut Pro, Premiere, or your favorite podcast editor.
Native Performance: Built for macOS. Minimal RAM footprint and maximum efficiency.
### Who is Sonar For?
Content Creators: Generate high-quality voiceovers for YouTube, TikTok, and social media without a mic.
Authors & Students: Listen to your manuscripts or research papers with voices that don't sound like robots.
Developers & Techies: A pro-tool that respects your hardware and your data.
