Handoff is a local-first Windows app that lets small businesses use AI on their private files without giving that data away. Send the question, never the data.

You drop in files, like a customer spreadsheet, and ask a normal business question. A local Llama 3.1 8B model analyses it on the PC, so the file never leaves the machine. Llama Guard 3 and my privacy checks screen every output, and Prompt Guard 2 blocks hidden instructions planted in files. When a question needs more power, Handoff can hand off to Muse Spark through the Meta Model API, but the cloud only ever receives masked, redacted text. Cloud access is off by default, admin-gated and has a kill switch.

I didn't pick Meta purely because it's a Meta Hackathon. I started with several models and routing approaches, then ran a pre-registered, local head-to-head of the Meta stack against the Google stack on synthetic data. Meta blocked 18 of 18 attacks in the sealed overnight run, and Google blocked none. So I built on Meta only.
