Aruanã checks the text you are about to send — in email, messengers and
AI assistants — and warns you before something goes wrong:- Detects personal data (Brazilian CPF/CNPJ, card numbers, phone, email,
PIX keys) and lets you redact it or block the message. - Validates Brazilian boletos and PIX QR codes, flagging invalid barcodes,
unknown banks, and inconsistent amounts or due dates. - Spots phishing patterns: links whose visible text does not match their
real destination, senders using free email to impersonate banks or
government agencies, and suspicious domains. - Works on WhatsApp Web, Telegram Web, Gmail, Outlook, Google Docs,
ChatGPT, Claude, Gemini, Copilot, Poe and Perplexity.
All analysis runs on your own computer. The AI models ship inside the
extension and no text is ever sent to a server.
