NudgeAI is a voice-first personal workflow agent that decides when you need a nudge, so you get fewer and better interruptions. Reminder apps either stay silent or nag, and most AI planners let a language model decide whether to interrupt you, which makes them unpredictable and impossible to audit.

NudgeAI splits the work. A deterministic rules engine decides whether to nudge. It checks quiet hours, cooldowns, snooze history, habit stacking and streak protection, and it sends a morning digest. Every suppressed nudge logs the rule that stopped it, so "why didn't it nudge me?" always has an answer. The model only writes the sentence you read, in your name and chosen tone.

The agent also acts on your behalf, with your consent. Say "push my 10am deep work to 11" and it plans the change with tool calls and returns a proposal. Nothing is written until you confirm. It never guesses a day or time, and every suggested task can be edited first. You can speak to it, or photograph a whiteboard, schedule or email and get proposed tasks and habits back.

Every agent turn stores a trace: the route chosen, each tool step, proposals, tokens, cost and latency. The app can read it back. The backend (FastAPI, PostgreSQL with pgvector, Redis) and the Expo mobile app are wired end to end, with 430 backend tests and 317 mobile tests. It is built for productivity and work routines, and gives no medical or wellness advice.
