Checkout and shipping address autofill

Fill the address half of a guest checkout in one click. The card fields are never touched — there's no card field in the extension to save one into.

Guest checkout is the version of this that hurts. You don't want an account at a store you'll buy from once, so you type the same address block you typed last week: name, street, apartment, city, state, ZIP, country, email, phone. Then the site rejects the phone format and you do part of it again.

What gets filled

• Contact email and phone
• First and last name, or a single full-name field
• Street address and the apartment or suite line
• City
• State or province, including dropdowns that list CA when your profile says California
• ZIP or postal code
• Country dropdowns, matched to whatever wording the menu uses
• Company name, on forms that ask for it

The dropdown problem

Address forms are where simple autofill tends to fall over, and it's almost always the menus. A country dropdown might list United States, USA, or US. A state menu might use two-letter codes. A phone field might want the country code split into its own box.

Because the actual options inside each menu are part of what the matcher sees, it picks the option the site offers rather than the exact string you typed into your profile. Same for a single "Full name" field when your profile stores first and last separately, and for split address lines.

One profile per address

Profiles are independent, and you switch the active one from the toolbar popup. The usual split:

• Home — your default, for personal orders
• Work — office address, company name, work email
• Anywhere else you ship — a family address, a second home

Switch profile, then fill. Nothing carries over from the last one.

Watch the checkboxes

Checkouts are full of pre-checked and unchecked boxes: create an account, save this card, email me offers, subscribe to the newsletter. Checkboxes are fillable fields, so it's worth adding a line to your profile instructions like "never opt in to marketing or newsletter checkboxes". The extension shows you what it filled and leaves an undo button, so a wrong tick is easy to catch before you pay.

Versus Chrome's built-in address autofill

Chrome's autofill is good at what it covers: a clearly labeled shipping form with standard autocomplete attributes, filled from an address you saved in your browser. If that's the whole of your problem, it's already handled.

Where it gives up is a form that doesn't follow the conventions — unlabeled inputs, a state menu of codes, a name split in an unusual way, a question about delivery instructions. This extension reads the whole form's structure instead of matching one field at a time, so it can work those out. The two don't conflict; the extension only fills when you ask it to.

What stays manual

• Card number, expiry and CVV
• Delivery speed, gift options and promo codes
• Anything inside a payment provider's embedded card frame
• Placing the order

Questions

• Will it fill my credit card number?

  No. Card number, expiry and CVV are never filled, and there's no card field in the extension to save one into. It handles the address and contact half of a checkout; payment is yours.

• How is this different from Chrome's address autofill?

  Chrome matches one field at a time against a fixed set of address types, and does that well on a conventional form. This extension reads the structure of the whole form, so it can pick the right option in a menu of state codes, handle unlabeled inputs, and answer fields Chrome has no category for.

• Can I keep more than one address?

  Yes. Keep a profile per address and switch the active one from the toolbar popup before you fill.

• Will it tick the marketing opt-in box?

  Checkboxes can be filled, so tell it not to: add "never opt in to marketing or newsletter checkboxes" to your profile's instructions. Everything it filled stays visible on the page, and undo puts it back.

• Is my address stored on your servers?

  Your profile is stored in your browser's extension storage on your own device. When you trigger a fill, the form's fields and the profile values go to our backend and our AI provider to work out the fill, and are not used for anything else. The privacy policy has the specifics.

• Job application autofill

  The other place the same fields come back forever: applying for jobs.

• How it works

  Save a profile, approve the prompt, fill the form. Plus what the extension never touches.
