NaLU
Extracts real values (names, dates, CPF) from chatbot replies instead of raw text
NaLU is an API and MCP server that parses what a user actually said in a chatbot reply — pulling out a name, email, yes/no answer, or Brazilian CPF/CNPJ with checksum validation — instead of saving the raw sentence. It ships 13 validators, including one that reads conversational context to tell a counter-offer ("can we do 48?") from a dollar amount. Pricing is metered per validation, around $0.0012 each, with 3,000 free credits per month and a stated 30-second integration.
What holds up
- +3,000 free credits per month before any cost kicks in
- +CPF/CNPJ validation uses the actual mod-11 checksum, not just a format check
- +Costs about $0.0012 per validation — sub-cent even at volume
Mind the limits
- −Built around Brazilian formats (CPF, CNPJ, ANATEL phone codes) — less relevant outside Brazil
- −Per-validation pricing means costs scale with every message you check, not a flat fee
