Case study · 2026
Vela
An AI that actually knows your money — taxes, investments and finances, answered with Banco Central data.
The context
Generic AI gives generic money advice. Vela grounds every answer in real Brazilian rates — Selic, CDI, IPCA — and your own numbers.
The challenge: make a finance chatbot feel trustworthy and calm — dark, precise, data-first, never hypey. A serif display for warmth, a mono for the numbers, a single green for confidence.
