AI form filler for Chrome: how to auto fill long forms and multi-page portals
Chrome already fills in your name, address and saved cards. That covers a lot of everyday forms. It does not help much with long application portals, supplier registrations, government forms or anything that spreads across several pages and asks questions in its own words. An AI form filler extension reads each field the way a person would, matches it to the information you gave it, and fills the whole page. This guide explains when each option makes sense and how to use an AI form filler safely.
Chrome autofill vs. an AI form filler
Chrome autofill is free, fast and built in. It recognizes standard fields such as name, email, phone, address and payment card, and fills them from what you saved. If a form only asks for those, autofill is the right tool and you do not need anything else.
Autofill stops where fields stop being standard: dropdowns with custom options, “describe your business in 200 characters,” dates in unusual formats, checkboxes, or a second and third page after you click Next. Template-based form filler extensions help with repeated forms you set up in advance. An AI form filler like Tabrein is different: you describe the task, and it reads the page, chooses options, types answers and moves through the pages.
How to fill a form with Tabrein
Tabrein is a Chrome extension with a side panel. It works in the Chrome where you are already signed in, in a tab it opens itself or one you share with it.
- Install Tabrein from tabrein.com and open the side panel.
- Sign in to the portal yourself if it needs a login. Tabrein does not type into password fields by default.
- Paste or type the information it should use, or attach up to 4 images, such as a screenshot of a document.
- Ask it to fill the form and stop before submitting.
- Check the filled pages, then allow the submission or fix what is wrong.
Ask Tabrein“Open the supplier registration page in this tab and fill it in with the company details below. Choose “Wholesale” as the business type. Go through all the pages but stop before the final Submit button and show me a summary.”
Why it asks before submitting
Submitting a form is hard to undo. Tabrein asks before submitting a form unless your message asked for exactly that. On top of that, Tabrein Guard holds anything the page would send after the assistant fills or clicks, such as a form submission or a data request, until you allow it. Questions appear as cards in the side panel.
You can stop a task at any time, and you can block whole sites you never want it to touch.
Limits to know about
Tabrein cannot upload files from your computer, so file attachment fields stay with you. It cannot solve CAPTCHAs. It does not type card numbers or one-time codes unless you gave them in the chat for that task. It works at a person’s pace, one task at a time, so it is meant for forms you need to fill, not for submitting hundreds of entries.
Each step uses credits: about 5 in Fast mode and about 15 in Smart mode. A long multi-page portal takes more steps than a single page. New accounts get 200 free credits.
