Fill Any Form.In One Click.Powered by AI.
Stop wasting time typing the same data over and over. FillFast detects every input on any page, fills it with realistic data in under a second, and remembers what you typed for next time. Free forever.
Filling forms is stealing your time
The minutes add up. The frustration compounds. The work isn't the form — it's everything before and after.
Live demos feel slow
You're typing in front of a client. They're watching. Every second counts. You're on field 3 of 12.
QA testing is repetitive hell
50 form submissions a day. Same fields. Same data. Same wasted minutes that add up to hours.
Onboarding the same flow again
New team member? New client? Same forms. Same explanation. Same wasted effort.
Three clicks. Zero setup.
No onboarding form. No mapping screens. No tutorials. Install, open a form, click Fill.
Add to Chrome
One click from the Chrome Web Store. No login, no signup, no setup form — the side panel opens to an empty dashboard ready to use.
Open Any Form
A small “Fill this form” badge appears in the corner of any page that has inputs. The side panel shows AI ready · live progress.
Click Fill
One click — or Alt+Shift+F. The AI walks every tab, generates context-appropriate values, and saves a template per domain for next time.
Built for the way real forms actually work
Six things we shipped to handle the messy reality of multi-tab, dynamic, JS-heavy forms — together, free.
Context-Aware AI
FillFast reads the page title, headings and submit button text to figure out if it's a login, registration, job application, loan form or bug report — then generates values that fit.
Multi-Tab Forms
Forms split across tabs or steps? FillFast walks every section automatically and fills them all in one click.
Per-Domain Templates
Every successful fill is saved as a template named after the site. Next visit, the same data is ready — edit anytime in Manage Templates.
Your Data Never Leaves
Templates stored locally in your browser. Only anonymous field labels go to AI — never your actual values.
Floating Fill Badge
A small badge appears in the bottom-right of any page with a form, so you never have to hunt for the extension icon. Click to fill, or dismiss for the session.
Realistic Local Data
Indian names, valid PAN, Aadhaar, IFSC, GST and PIN codes — coherent across fields. Or skip the template entirely and let pure-faker fill a different persona every click.
FillFast vs the rest
Honest, side-by-side. Checked every form-fill extension on the Chrome Store in May 2026.
