Intelligent Form Filler

About

Intelligent Form Filler scans any web form and fills every field with realistic, coherent data — either powered by AI or generated instantly offline.

HOW IT WORKS

The extension reads every field on the page — labels, placeholders, input types, select options, validation rules — and uses that context to produce data that makes sense together. A generated person's name matches their email, their city matches their state and zip code, and document numbers pass real validation.

TWO FILL MODES

⚡ AI Mode
Sends field metadata to an AI model that understands what each field is asking for. It generates contextually appropriate values: realistic descriptions for text areas, coherent addresses, proper phone formats, and plausible answers for domain-specific questions. Choose between three providers:
- Anthropic (Claude Sonnet 4)
- OpenAI (GPT-4o-mini)
- Google (Gemini 2.0 Flash)

🎲 Faker Mode
Instant offline fill — no API key, no network requests, no cost. Uses built-in data pools with proper Brazilian locale support. Generates valid CPF and CNPJ numbers with correct check digits that pass form validation. Also handles names, emails, phones with real area codes, addresses, dates, passwords, and more.

VALID DOCUMENT NUMBERS

Both modes generate CPF and CNPJ numbers with mathematically correct check digits. The Faker engine computes verification digits using the official algorithms, so generated documents pass any client-side validation. Area codes (DDDs) are real and match the generated city.

SUPPORTED FIELDS

- Text inputs (name, email, phone, address, documents)
- Date, number, range, URL, and password fields
- Textareas with contextual placeholder text
- Select dropdowns and radio button groups
- Checkboxes
- Contenteditable elements

FRAMEWORK COMPATIBLE

Works with React, Angular, Vue.js, and vanilla JavaScript forms. Uses native value setters and dispatches input, change, and blur events so controlled components pick up the changes.

LOCALE SUPPORT

Choose from Portuguese (Brazil), English (US/UK), Spanish, French, German, or Japanese. The AI adapts names, phone formats, addresses, and cultural conventions to the selected locale.

PRIVACY & SECURITY

- Your API key is stored locally on your device — never sent to third parties
- In AI mode, only field metadata is sent to the provider you choose (no page content, no personal data)
- In Faker mode, everything runs locally — zero network requests
- All generated data is fictional
- No analytics, no tracking, no telemetry
