The project
FinWise doesn't just track expenses. Its “Real Number” computes what's left after fixed costs, savings goals and current spending — and Sofía, its AI advisor, answers “can I afford this?” with the real impact on your wallet. Logging an expense takes seconds: voice, receipt photo or text.
What it does
- Real Number: what you can actually spend, always visible.
- Sofía (AI): a Claude-powered financial advisor, streamed.
- Multi-input capture: voice (Whisper), receipt OCR (AI vision), share extension or manual.
- Native iOS: iPhone widgets, Apple Watch app + widget, 7 currencies.
