DoomTax
Focus app where you stake on your intention,AI judges the outcome and slips fund a your charity.
About
DoomTax is a personal focus app that turns intention into accountability. You start a session by stating exactly what you plan to do and choosing a small HBAR stake on Hedera testnet. At the end, you submit evidence of your work, and a private AI coach running on 0G evaluates whether you kept the intention you set at the start. If you kept it, your stake is returned; if you slipped, the forfeit is routed to a charity recipient. The app is built as a World Mini App with a Next.js frontend, server-side Hedera settlement, privacy-aware HCS logging, and a user-first design where ambiguity, failed inference, or contested outcomes resolve in the user’s favor.

Say it out loud: *we do not need to surveil you, because we are not trying to catch you.* We are a webview with no OS access, so OS-level monitoring is not on the table at all.
