About VaultCloud AI
Free tools for everyday file jobs, built so your files never have to leave your device.
Last updated 8 November 2026
Why this exists
Most online converters ask you to upload your photo, PDF or spreadsheet to their server. That's a real risk for ID cards, bank statements, contracts and family photos. VaultCloud AI does the opposite: the page sends the tool to you, and your browser does the work.
How it works
Each tool runs on WebAssembly and, where available, your graphics card through WebGPU. AI models are downloaded once from Hugging Face and cached by your browser. Your files are read into the tab's memory, processed, and the result is saved straight to your device. The privacy policy lists exactly what is downloaded and from where.
Keeping it safe
The tools are for everyday, lawful use. Before first use, everyone agrees to the terms of use. Images are checked on the device for explicit or violent content, and text the tools produce is checked for threats and hateful language. Some features are deliberately left out because they are mostly used to cause harm, such as face swapping, voice cloning, watermark removal and editing the text of documents.
