How it works
Credits are spent only when the AI builds or changes something.
Building a site and changing it is where the AI's effort goes, so that is what credits pay for. Ask for a lot one month and very little the next. You buy what you use.
Start on the free plan
Your site is published on its own address. Your first site comes with 150 credits to build it, with no card required.
Buy credits for the work
Spend credits when you ask the AI for something. What an edit costs depends on the edit, because rewording a heading and rebuilding a page are not the same job. Every one is itemised so you can see where they went.
Go Pro when it suits you
Pro adds a monthly allowance of credits, forms and a domain of your own. Choose how many credits it comes with, and change it whenever you like.
Top-ups
A top-up is a one-time credit purchase.
A top-up is one payment for as many credits as you choose, on any site. The credits sit there until you spend them.
Any amount
Buy a few credits for one change or a lot for a rebuild.
Never expires
Purchased credits stay with the site until you use them.
Free to publish
Credits pay for the AI. Keeping the site online on the free plan costs none.
How far a top-up goes is down to you: a site you rebuild every week spends more than one you leave alone, and the balance and what went where are both on the dashboard. If you find yourself topping up most months, Pro brings a monthly allowance and adds more for the site.
Who it suits
Where top-ups fit well.
A site with a busy season
A wedding photographer before spring, a ski shop before winter: ask for a burst of changes when it matters, and buy credits for exactly that.
A site that rarely changes
A menu, an address, some photographs, a phone number. Publish it on the free plan and buy a few credits on the occasions you want something new.
A site that is growing
When it needs a form, a domain of its own or more room, move it to Pro and choose the monthly AI allowance that fits.
A site you built for someone else
Build it and hand it over. The owner needs no subscription to have it published, and if they want the AI to change something later, they buy a few credits then.
Questions about free
What does free actually include?
A published site on its own address at mightybuilder.site, with HTTPS. Your first site also comes with 150 credits to build it, once per person. The full Free and Pro comparison is on the pricing page.
Do credits expire?
No. Purchased credits remain available at the same value until you use them.
What happens when the credits run out?
The AI stops editing, and that is all. The site stays exactly as you left it, because credits pay for the AI and not for hosting. Buying more starts the editing again whenever you like.
When is Pro the better choice?
When you want forms, a domain of your own and a monthly AI allowance. Credits arrive every month without you thinking about it, so it is also the better fit for a site you work on regularly.
Can I switch between them?
Yes, either way, from Billing. Credits you bought stay with the site as you move between Free and Pro.
What address does my site get?
Every site, free or Pro, gets its own address at mightybuilder.site with HTTPS, renewed automatically. With Pro you can also connect a domain of your own at no extra charge. You buy the name from a registrar and pay them for it.
