At its core, SatLegacy is a one-tap planner that combines AI-assisted prompts, secure storage, and printable outputs. It's free for basic use, with premium upgrades for advanced multi-sig setups and ongoing audits. Users start by inputting wallet details (optionally, to build trust), and the app generates a customized "Sat Will" that's encrypted and shareable only with trusted heirs via time-locked reveals or QR codes.
