Smart Field Detection

Four-signal classification — autocomplete attributes, regex heuristics, type attributes, and label text — with a two-pass scan that prioritizes high-confidence matches.

⚡

Framework-Aware Filling

Uses native property setters to bypass React, Vue, and Angular interceptors. Dispatches events in the correct order so framework state stays in sync.

🛒

Cart Extraction

Extracts shopping cart data from JSON-LD, Microdata, Open Graph, and DOM heuristics. Returns structured product info, totals, and currency.

📱

Cross-Platform

One core engine, four platform adapters. Works in any WebView — React Native, Android WebView, WKWebView, or a plain iframe.

🎯

Billing Context Awareness

Automatically distinguishes shipping and billing address fields by walking the DOM tree and inspecting parent containers.

🔒

Privacy-Conscious

Sensitive fields like passwords and SSNs are excluded from value capture. No data leaves the device — everything runs locally inside the WebView.
