Private AI Studio

This free, privacy-first toolkit runs directly in your browser and handles everyday media and document tasks without uploading anything. Core capabilities: • Audio to text with timestamped transcripts • Video captioning with editable SRT and VTT export • Translation for paragraphs and subtitle files • PDF summarization in seconds • Image descriptions and alt text generation • No account, sign-up, or installation required. The model is downloaded once and stored in your browser, then reused in future sessions. Because processing happens on your own processor, audio, video, PDFs, and images never leave your phone or computer. There is no server copy to leak or retain, and once a model is saved, the work itself needs no internet connection. Creators, journalists, students, and accessibility-focused teams will find it useful for quick turnarounds. Load finished captions into YouTube, Premiere, or CapCut, or prepare alt text for websites. It is ideal for sensitive interviews, confidential documents, and anyone who wants offline-capable tools without subscription costs.
