New Chrome extension · EN / ES

Any form, filled in one click.

Intellisense Forms detects every field on the page —native, ARIA, shadow DOM, iframes, custom selects— and fills it with realistic data in English or Spanish. For QA, development and demos that don't look like test data.

Features

Works with any form.

No matter how it's built: plain old HTML, a React app full of custom components or a form hidden inside an iframe.

01

Detects every field.
Even the tricky ones.

Reads labels, name, autocomplete and placeholders to work out what each field is. And reaches where others can't.

English or Spanish.
For real.

Names, phone numbers, addresses and dates in each language's format. And, if you like, each field in its own.

Data that passes validation.

IBANs with correct check digits, Spanish DNI and NIE with their check letter. Or write your own regex.

Types like a person.

Uses the native setter and fires the events frameworks listen to. Your state notices.

No servers. No accounts.
No surprises.

Data is made up in your browser, AI included, and templates are stored on your machine. It only asks for the permissions it really needs.

How it works

Three steps. Zero “asdf”.

01

Open the panel

Click the icon on any page. Intellisense analyses every form and shows you each field with its type.

02

Tweak if you want

The automatic guess is usually right. If not, change the source, language or casing of any field. You see the example instantly.

03

Fill and save

One click on Fill all. Save it as a template and next time you fill it without opening the panel.

Live demo

Don't take our word. Try it.

This form is real, and so is the panel: it's the same extension you install, loaded on this page.

You can drag and resize the panel. Its interface is in Spanish for now, but the data comes out in English. Try switching it to Spanish or picking another source for a field.

FAQ

What you're probably wondering.

Does it send my data, or the page's, anywhere?

No. Data is generated in your browser and templates are kept in the extension's local storage. There are no accounts and no servers. It's all in the privacy policy.

Does it work with React, Vue or Angular forms?

Yes. It writes through the field's native setter and fires the input and change events, so your app's state updates as if a person had typed it.

What about custom dropdowns or split date fields?

Those too. It opens role="combobox" elements to read their options and pick one, and types into date fields split into day, month and year.

Can I use my own values?

Of course: your own list (random or in order), fixed text, a regex pattern or leaving the field empty. And choose UPPERCASE, lowercase or Title Case.

Are the IBANs and IDs it generates valid?

They pass format validation: IBANs carry their check digits and Spanish DNI and NIE numbers their check letter. They're made up and belong to no one.
