What is Zeraku? Free AI Tools That Run in Your Browser
Zeraku is a collection of AI-powered tools you can use right now — no installation, no account required. Audio transcription, image compression, meeting minutes generation, and more, all completely free. Every tool runs entirely in your browser, so your files never leave your device.
Why People Choose Zeraku
Most online tools upload your files to external servers for processing. Meeting recordings, personal photos, business data — sending sensitive files to the cloud can feel uncomfortable.
Zeraku uses WebAssembly and browser APIs to process everything on your device. No data leaves your machine, and you still get cloud-quality results.
