How It Works

From your spreadsheet to a finished form
in four steps

AutoFill Portal reads the form in front of you, matches every field to your data, and fills it in — no copy-pasting, no hunting for the right cell. Permits, vendor portals, registrations, PDFs: same flow every time.

1

Install the Chrome extension

Install AutoFill Portal from the Chrome Web Store and create a free account. Your key is stored in the extension — no manual entry after signup. The extension stays idle until you open its popup, and only reads form fields on the pages you choose to fill.

What you need

2

Upload your data once

Click the extension icon and upload your spreadsheet. Each row is one record — address, type, scope, value, contact, and anything else your forms ask for. Column names are flexible; AutoFill Portal recognises hundreds of variations automatically. Fill in your profile once (license, insurance, phone, email, address) and it's reused on every form, forever.

3

Open any form or portal

Navigate to any online portal, application, or web form — government permit sites, vendor portals, registration pages. AutoFill Portal detects every field automatically in the background: inputs, dropdowns, text areas, even rich-text editors. The popup shows how many fields were found and which data matched.

Green = exact match Yellow = fuzzy match Blue = from your profile Orange = AI-suggested
4

Click Auto-Fill and review

Click Auto-Fill All and every matched field fills instantly. Color-coded highlights show the confidence of each fill so you can spot anything to adjust before submitting. Use the Review tab to step through every field or pick a different column — your corrections are saved and applied automatically next time. For PDFs, the PDF Filler matches every field and you download the completed file, all in your browser.

Common questions

What forms and portals does it work on?
Any web-based form with standard inputs — flat HTML forms, Accela Citizen Access, EnerGov, OpenGov, vendor portals, and thousands of custom sites. It detects fields automatically, so there's no per-site setup. Hosted document viewers like DocuSign or SharePoint show a clear message instead of attempting to fill.
What goes in the spreadsheet?
Each row is one record — the details your forms ask for. You don't need our exact column names; AutoFill Portal recognises your existing ones through fuzzy matching. Download the sample CSV to see supported columns with examples.
Is my data secure?
We never sell or share your data, and your project spreadsheet isn't retained in our database. For exactly what's stored and what's sent for form detection, see our privacy policy.
Does it work on PDF forms?
Yes. The PDF Filler accepts any PDF. Claude AI reads the form and identifies every field, matches your data using the same pipeline, and you download the completed PDF — nothing is uploaded to a server.
What if a field doesn't match?
Unmatched fields appear in the Review view with the closest column candidates. Pick the right one and your correction is saved, then applied automatically on every future visit to that form.
