Fillr

About

Every developer, QA engineer, or marketer does this dozens of times a day: open a form, click the first field, type John, tab, type Doe, tab, type [email protected], tab... for every single form, every single test run, every single demo prep, every single job application.

It's the most repetitive task on the web. And the data is always garbage, which means your app always looks broken in demos and screenshots.

Fillr fixes this with one shortcut.

Hit Alt+Shift+F on any form and every field fills instantly with coherent, AI-generated data. Real names. Real addresses. Emails that match the name. Phone numbers in the correct format for the correct country. Passwords that actually pass validation.

━━━━━━━━━━━━━━━━━━━━━━
WHAT MAKES FILLR DIFFERENT
━━━━━━━━━━━━━━━━━━━━━━

Every other form filler generates random garbage: "[email protected]", "123 Fake St". Fillr uses AI to generate data that makes sense together. The name, email, company, and address all match. Every time.

━━━━━━━━━━━━━━━━━━━━━━
KEYBOARD SHORTCUTS
━━━━━━━━━━━━━━━━━━━━━━

Alt+Shift+F — AI fill all fields
Alt+Shift+R — instant random fill (local, no AI, no limit)
Alt+Shift+T — open the quick template picker
Alt+Shift+C — clear all filled fields

All shortcuts fully customisable in Chrome settings.

━━━━━━━━━━━━━━━━━━━━━━
QUICK TEMPLATE PICKER
━━━━━━━━━━━━━━━━━━━━━━

Press Alt+Shift+T on any page and a keyboard-navigable picker slides in. Arrow keys to browse, 1–9 to jump directly to a template, Enter to fill. Your most-used templates are one keypress away — no mouse, no panel, no friction.

━━━━━━━━━━━━━━━━━━━━━━
PERSONAS
━━━━━━━━━━━━━━━━━━━━━━

Create a "French B2B Manager" persona once. Now every AI fill gives you a consistent French identity: French name, French company, Paris address, .fr email domain. Create as many personas as you need — "US Student", "UK Enterprise Buyer", "German Freelancer" — and switch between them in one click.

━━━━━━━━━━━━━━━━━━━━━━
TEMPLATES & PROJECTS
━━━━━━━━━━━━━━━━━━━━━━

Fill a form once, save it as a template. Every run after that is instant and deterministic — no AI call, no variation, no weekly limit. Just the exact same data, every time.

Organise templates into projects by domain (e.g. "app.acme.com", "linkedin.com"). When you're on a matching site, its templates appear automatically in the panel and the quick picker.

━━━━━━━━━━━━━━━━━━━━━━
WHO IT'S FOR
━━━━━━━━━━━━━━━━━━━━━━

→ QA engineers running the same form flows 50 times a day
→ Developers who hate breaking their flow to type fake data
→ Marketing and sales teams who need clean, realistic data for demos and screenshots — not "John Doe at [email protected]"
→ Anyone applying to jobs who fills the same work history, address, and contact details on every job board, every day
→ Anyone who interacts with the same web forms repeatedly and wants their time back
