The problem

Tired of retyping the same information?

Every job application, every signup, every registration — you fill web forms with the same name, email, phone, and address. Over and over.

Time wasted

Minutes per form, hours per week. Time you could spend on work that matters.

Typos & mistakes

Copy-pasting from notes leads to errors. One wrong digit can cost you an interview.

Mental fatigue

By the 10th application, you're exhausted. Repetitive data entry drains focus.

How it works

Set up once. Never retype again.

Three steps to stop filling the same fields by hand, on every website, every time.

1

Create your profiles

Set up a profile for each context — Work, Personal, Job Applications, School. Choose an icon and colour, then add fields manually or save them from a form later.

2

Save your fields

Add fields manually in settings, or fill out any form as you normally would and press "Save" or Ctrl+Shift+S. TETRAform captures field names, types, and values into your selected profile — whether that's the global default or a domain-specific one. Sensitive fields like passwords, credit cards, and CAPTCHAs are automatically blocked.

Mac: Cmd+Shift+S to save

3

Auto-detect & fill anywhere

Visit any website with a similar form. TETRAform's smart field detection automatically matches your saved data to the right inputs — even when field names differ between sites. Your fields transfer seamlessly across platforms. Click "Fill" in the Assistant Bar, open the extension popup, or press Ctrl+Shift+F.

Mac: Cmd+Shift+F to fill

FAQ

Frequently asked questions

Is TETRAform really free?
Yes — free to install and use. The free plan includes up to 3 profiles, 15 form fills per day, and all core features. A Pro plan with unlimited fills and profiles is coming soon. No credit card, no sign-up required.
Is my data safe?
Completely. All profile data is stored in your browser's local storage — it never touches a server. No cloud sync, no account, no data collection. TETRAform also automatically detects and blocks sensitive fields — passwords, credit card numbers, CVVs, CAPTCHAs, and OTP codes are never saved, even if you click Save. You can export or delete everything at any time.
Does it work on all websites?
TETRAform works on the vast majority of web forms — job boards like LinkedIn and Indeed, scholarship portals, CRMs, contact forms, and more. You can also ignore specific websites where you don't want the assistant to appear.
How do profiles work?
Each profile stores a different set of information — e.g. "Job Applications", "School", "Personal". You can add fields manually, or fill out any form once and press Save to capture all the fields into your profile automatically. Next time you visit a similar form, just click Fill. You can also link a profile to a website so it activates automatically when you visit.
Do I need to create an account?
No. Install TETRAform, create a profile, and save your data from any form you fill — or add it manually. No email, no password, no sign-up. Your data lives in your browser — nowhere else.
Can I transfer my data to a new computer?
Yes. Use the Backup & Restore feature to export your profiles to a file. Install TETRAform on your new machine and import — all your profiles are back instantly.

One click instead of 20 fields typed by hand.

Job seekers, students, freelancers, sales reps, and anyone tired of retyping — TETRAform fills your forms so you don't have to.
