Cancer research toolkit
Describe a cancer treatment plan and get a second opinion with citations, drawn from six public medical databases by an AI model that runs on your own computer. Nothing leaves the machine. A research tool, not medical advice.
Tamper-evident downloads
Checks a download while it streams in and stops at the first tampered byte, so a tampered file never fully lands on your disk. A signature in a public log (Sigstore) shows who published it.
