AI Autofill Tester

a extension for developers, testers, and quality assurance teams. It recognizes fields in web forms, generates safe test data locally, and saves reviewed configurations as reusable scenarios. This reduces repetitive data entry and speeds up functional, regression, and acceptance testing for forms. The extension does not submit forms or click page buttons. Users can review and edit every value before filling and choose exactly which fields to include. ## Key Features - Smart scanning: Recognizes `input`, `textarea`, `select`, checkbox, radio, `contenteditable`, and open Shadow DOM fields. - Semantic field recognition: Uses name, label, ARIA, placeholder, autocomplete, nearby text, and HTML constraints to identify names, email addresses, phone numbers, addresses, dates, passwords, and other data types. - Local AI first: Prefers the built-in Prompt API. If it is unavailable, users can approve a local WebLLM model download. When AI cannot be used, the extension falls back to local field rules. - Editable preview: Review, edit, enable, or exclude each field in an on-page overlay. Both fixed values and local random generators are supported. - Length controls: Set minimum and maximum lengths for supported generated values while respecting the field's own HTML constraints. - Fast filling: Fill empty fields on the current page directly while preserving existing values by default, or use the preview to choose whether existing values may be overwritten. - Scenario management: Save multiple named scenarios by domain, subdomain, and page path, then sync them across signed-in devices with Sync. - Reliable reuse: Saved scenarios rematch fields using stable attributes and semantic fingerprints. Ambiguous matches are never filled automatically. - Text import and export: Copy scenarios in a readable text format and import scenario text written with either English or Chinese headers. - Safe undo: Undo the most recent fill. If a user or the page changed a field afterward, the extension preserves that later change.
