AI Test Data Filler

AI Test Data Filler fills the form on your current tab with realistic, fictional test data in one click. Built for testers and developers who are tired of typing "test test test": Random names, surnames, emails, addresses, dates and texts, different on every click. Data that stays consistent: a selected country drives the address, postal code and phone number; ages match dates of birth. Respects field types, length limits, number ranges, patterns and drop-down options. Picks drop-downs and radio buttons at random, and waits for dependent lists (such as regions) to load. Large-data test: fields that state a length limit (maxlength, a counter like 0/500, "max 500 characters") get long, readable text of exactly that length, ending in END so you can see if the form cuts it off. Never submits a form. Skips password, file and payment card fields. Bring your own AI: you enter your own Claude (Anthropic) or ChatGPT (OpenAI) API key. The extension only talks to the provider you select, using your key. You pay that provider directly, typically a fraction of a cent per fill. Privacy: your key stays in your browser. Only a description of the form's fields (labels, names, types, placeholders, options) and the choices already selected on the page are sent, and only to the provider you chose. Nothing you typed, no page text, no passwords. No analytics, no tracking. Works on http and https pages. Custom widgets that are not standard inputs (some date pickers and searchable dropdowns) are not filled.
