Conversational personal finance assistant powered by Generative UI (A2UI). LLM intent parsing is paired with a 100% deterministic, testable TypeScript engine for invoices, installments, balances and projections.

Provide financial analysis through natural language without delegating monetary calculations to the model. AI only interprets requests and selects tools; amounts, installments, statements and projections remain reproducible, validated and auditable.

→ Portuguese conversational flow for recording transactions, reviewing statements, analyzing spending and simulating scenarios.

→ Closed, validated A2UI catalog that renders financial cards, tables and charts from tool results.

→ Deterministic financial engine using integer cents with coverage for installments, statement cycles, projections and comparisons.

→ Supabase persistence with authentication, RLS-protected Postgres, auditable history, and confirmable, reversible changes.

→ POC 1.0 validated with unit tests, deterministic agent evals, E2E tests and continuous integration.
