The AI browser that fills forms for you

Form filling on the live page, not a copy

LLM Browser is a full desktop browser with a docked AI assistant in the same window. When you ask it to complete a form, it works on the real, signed-in page in front of you. It locates the fields, types the values, makes the dropdown and checkbox selections, and submits, with every step visible in the bridge panel. There is no separate tool and no hidden tab you cannot follow.

From one field to a whole flow

Because the assistant can navigate, click, scroll, read the page, and switch tabs, it handles forms of any length:

• Single fields and quick searches typed into a box and submitted.
• Long sign-up and registration flows spread across several screens.
• Repetitive data entry where the same details go in over and over.
• Multi-step tasks that gather details across pages before filling a final form.

You ask in plain words, like “fill in this application with my usual details” or “complete the contact form and submit it,” and the assistant does the clicking and typing while reporting back as it goes.

You stay in the loop

Form filling is exactly the kind of task where you want oversight. Because the assistant lives in the same window as the page, you see each field it touches and each value it enters in the docked panel. You can step in, correct it, or stop it at any point before anything is submitted, so automation never means losing control.

Keep form data private

Forms often carry personal details, so where the AI runs matters. You can power the assistant with a local model through the Local Server (Ollama or LM Studio) or built-in Local AI GGUF connection, so the model runs on your own machine and your form data does not have to leave your computer. See the AI browser with a local LLM for the full private setup.

How to get it filling forms

Setup is quick. Install LLM Browser like any desktop browser, then open Settings → LLM Connection, choose how to power the assistant, and press Test for a green Connected banner. Browse to the page that has the form, then type your request into the bridge panel along the bottom, for example “fill out this newsletter sign-up with my email and submit it.” The assistant reads the form, enters the values, makes the selections, and submits, narrating each step as it goes so you can follow along.

Forms it is good at

The same navigate, read, click, and type abilities let it handle a wide range of everyday forms:

• Contact and enquiry forms on company sites.
• Sign-up and registration flows with several screens.
• Job application forms that ask for the same details repeatedly.
• Search and filter forms on job boards, listings, and catalogues.
• Survey and feedback forms with mixed text, dropdown, and checkbox fields.

For anything you would rather not retype by hand, the assistant turns a chore into a single plain-language request.

Tune it for accuracy

Each connection has its own reasoning level, system prompt, and step limit. For careful form work you can raise the reasoning level so the assistant reads labels closely, and use the system prompt to tell it which details to use and when to pause for your confirmation before submitting.

Where to go next

Form filling is one job of the wider browser with a built-in AI assistant. If you want to script repetitive form runs without sitting and watching, you can also control the browser with an LLM over its API.
