Autofill AI Ninja — Context Aware AI Form Filler

AI form filler Chrome extension to autofill forms with test data. React, Vue, multi-step. Free Gemini or Groq key.

AI Form Filler is a Chrome extension that autofills web forms with realistic AI-generated test data. Use this AI form filler to fill forms automatically on signup, checkout, and onboarding pages — including React forms, Vue forms, Angular forms, and multi-step form wizards that normal autofill and dummy-data tools get wrong. If you need a Chrome form filler for QA, a test data generator for frontend work, or a way to autofill multi-step React forms without clicking every field, this extension is built for that. You bring your own API key. You do not need a paid OpenAI or Anthropic account. Google AI Studio (Gemini) and Groq Cloud both give a free API key with enough quota to autofill forms while you test. No credit card. Recommended setup for fewer errors: • Chrome extension provider: Google AI Studio • Model: Gemini 3.1 Flash • Alternative: Groq Cloud with Llama 3.3 70B Versatile AI FORM FILLER FEATURES • Autofill text fields, dropdowns, radio buttons, checkboxes, ARIA comboboxes, and contenteditable • Fill multi-step forms automatically (clicks Next / Continue, does not click Pay or Place order) • Keep names, email, and phone consistent across wizard steps • Repair values using the page’s own validation messages • Custom instructions: phone format, Japanese names, a specific city or address • Hybrid fill (heuristics + AI) or heuristics-only with no API key WHY THIS CHROME FORM FILLER WORKS ON REACT AND VUE Most form filler extensions set the field value in a way React, Vue, Svelte, and Angular ignore, so the input snaps back empty. AI Form Filler uses native setters and real keyboard-style events so the framework keeps the test data. Multi-step wizards that reuse the same input nodes still get a fresh fill on every step.

The website you fill never sees it. Form contents go only to the AI provider you chose (Gemini, Groq, OpenAI, and others). Skip password and payment fields if you want. WHO SHOULD USE THIS AI FORM FILLER Frontend developers, QA testers, and product teams who need to fill web forms with dummy data again and again while testing React apps, Vue apps, and multi-step checkout or onboarding flows.
