Online forms are everywhere: job applications, school enrolment, HR paperwork, government services, event sign-ups, customer surveys, supplier onboarding. Most of them ask for the same details you have typed a hundred times before. If you fill more than a few forms a week, automating part of the work is one of the easiest productivity wins available.
There is no single "right" tool. The best method depends on how many forms you fill, how complicated they are, how sensitive the data is, and whether you can write code. This guide compares the six common approaches, from the one already built into your browser to fully scripted automation.
The six ways to fill a web form
- Typing by hand. Slow, but you control every character. Still the right choice for one-off forms, legal declarations, and anything you need to think about carefully.
- Browser autofill (Chrome, Edge, Brave, Safari, Firefox). Free and built in. It fills names, email addresses, phone numbers, postal addresses, and payment cards, but only when the website labels its fields with standard autocomplete names.
- Password managers. Excellent for logins, and many can store an identity card with your name and address. They rarely help with custom questions, dropdowns, or long multi-section forms.
- Text expanders and clipboard managers. You type a short abbreviation and it expands into a saved paragraph. Great for repeated free-text answers like a professional summary, but you still click into every field yourself.
- Form-filler extensions. These read the label and context of each field and fill the whole page from saved profiles: text, dropdowns, radio buttons, checkboxes, dates, and file uploads. Some add optional AI for questions they have never seen.
- Scripts and RPA (Selenium, Playwright, Puppeteer, or robotic process automation platforms). Fully automatic and able to run unattended, but they need programming skills or paid licences, and they break whenever the page layout changes. Best for repetitive internal business processes on systems you own.
Comparing the methods at a glance
- Effort to set up: browser autofill and text expanders take minutes; a form filler takes 10 to 20 minutes to build a profile; scripts take hours to days.
- Coverage: browser autofill covers contact and address fields; form fillers cover most of a typical form; scripts can cover everything on one specific site.
- Maintenance: browser autofill and form fillers adapt to new sites automatically; scripts need updating when a site changes.
- Privacy: tools that keep your data encrypted on your device and send nothing by default are the safest; cloud-based tools and AI services see whatever you send them.
- Cost: browser autofill is free, most form fillers have a free plan, RPA platforms are usually priced for businesses.
What to automate, and what to keep manual
Automation is best at information that is the same every time. Keep a human in the loop for anything that needs judgement or carries legal weight.
- Automate: names, contact details, addresses, links, work and education history, standard yes/no answers, and document uploads like a resume or certificate.
- Assist, then edit: open questions such as "Why do you want this role?" An AI draft is a starting point, not a finished answer.
- Keep manual: signatures, declarations, national ID and bank numbers on sensitive forms, and any answer that changes often.
- Never automate: CAPTCHAs and other bot checks. They exist to stop automated submissions, and respecting them keeps you within a site's rules.
Setting up a form filler in practice
- Install the extension in your browser and pin it to the toolbar.
- Create a profile for each context, for example one for job applications and one for school forms. Many tools, Aullevo included, let you build a profile from your resume with any AI chatbot.
- Open a form and preview which fields the tool detected before filling.
- Fill the page with one click or shortcut, then read every answer.
- Correct anything wrong, update your profile so it is right next time, and submit.
Aullevo is one example of this approach. It is a free extension for Chrome, Edge, and Brave that matches fields with an offline keyword engine, so standard fields are filled with no internet request and no AI key. Optional AI Smart Fill uses the provider you choose with your own key, a Multi-link queue fills a list of pages in one go, and Auto-Pagination handles multi-page forms.
Tip: Start small. Automate the one form you fill most often, measure how long it takes before and after, and expand from there.
Use automation responsibly
Filling your own, truthful information faster is what these tools are for. Do not use automation to submit forms in bulk on behalf of other people, to spam contact forms, or to get around a site's limits. Read the terms of any service you automate, and stay present for the final review and submit.
