SmartFill – AI Form Filler & Test Data Generator

SmartFill: one-click form filler. Autofill any form with realistic test data for 20 industries, or with AI (OpenAI, Claude, Gemini).

SmartFill fills web forms for you in one click. It is made for developers, testers and anyone who is tired of typing the same details again and again. HOW IT WORKS Open a page with a form, click the SmartFill icon and press Fill form. Text boxes, dropdowns, radio buttons, checkboxes and dates are all filled. Press Generate again for new values, or Undo to put the page back the way it was. REALISTIC TEST DATA, NO SETUP SmartFill makes up one believable, clearly fake person for each fill, so the name, email, phone and address all match. It reads the label you see on the page, so an amount field gets an amount and a date field gets a date in the same format the page uses. Business and ID numbers follow real formats for India, the US and the UK. This works offline and needs no account. INDUSTRY PROFILES Choose from 20 industry profiles, such as healthcare, banking, logistics and e-commerce, or leave it on Auto and SmartFill picks one from the page. OPTIONAL AI FILL Connect the AI service you already use with your own API key, and SmartFill asks it for values that suit the form. You can describe the person you want, by typing or by voice. If the AI skips a field, test data fills the gap. YOUR LOGIN DETAILS Set one password for every sign-up form, use your own email address with a new alias each time, or use a free temporary inbox and open it straight from the popup to read the verification email. HANDY EXTRAS - Alt+Shift+F fills the page without opening the popup - Keep my values only fills empty fields - Safe Filling Mode leaves passwords, ID numbers and consent boxes alone PRIVATE BY DESIGN There is no SmartFill server and no tracking. Settings and keys stay in your browser. Test data never leaves your computer. AI and voice requests go only to the service you choose, and only when you ask.
