About VoxCaption Studio

VoxCaption Studio is an independent software studio that builds privacy-first AI apps which run on your own device. We make desktop and mobile tools for video creators, developers and everyday users — designed so your files and data never leave your computer or phone.

What we build

We focus on practical AI tools that solve one real problem each, work offline wherever possible, and respect your privacy by processing data locally instead of uploading it to a server. Our current apps:

• VoxCaption Studio — all-in-one AI video translation, dubbing, captions, transcription and conversion for Windows.
• Phondex — on-device file search with offline OCR for Android: find text inside photos, PDFs and documents.
• PHONEINT — a fast contacts, number and call-log search app for Android.
• AI Project Guardian — encrypted automatic code snapshots that let developers undo bad AI edits in one click.

Why we built it

Most modern "AI" tools send your private files to the cloud. We believe powerful AI features and real privacy are not mutually exclusive. Every app we ship is built around a simple rule: your data stays on your device. Internet is used only when a feature genuinely requires it — and never to harvest your content.

Our principles

• Privacy by default — local processing, encrypted storage, no hidden tracking.
• One honest price — simple licensing, generous free trials, no stacking subscriptions.
• Built to last — native apps you actually own and can run offline.
