Filli AI

Filli AI is a browser extension engineered for software developers, QA engineers, and testers who need to populate web forms with realistic test data or boundary stress cases without manual field mapping.

Unlike traditional form fillers that insert purely random alphanumeric strings that often break strict validation (such as regex phone patterns, corporate email domains, and E.164 formats), Filli AI analyzes surrounding DOM context, labels, placeholders, and validation constraints to generate contextually valid mock data.

Key Features: • Context-Aware Autofill: Dynamically detects field intent (names, corporate emails, phone standards, URLs, and JSON) to pass frontend validation rules. • 2-Pass Reactive Engine: Handles dependent and conditional fields (e.g. state or postal code fields appearing dynamically after selecting a country) by re-scanning the DOM after initial event dispatches. • QA & Boundary Mode: Injects boundary limits, max-length overflow strings, unicode fuzzing, and basic OWASP/XSS injection vectors to test sanitization. • Persona Vault: Switch between general consumer profiles, B2B corporate personas, or custom prompt instructions. • Privacy First: DOM parsing runs client-side. No filled values or sensitive session credentials are stored or tracked. Supports Bring Your Own Key (BYOK) for direct API usage.
