Using an AI website builder from an existing website starts with choosing what to keep. Your old site can supply useful facts and ideas. It can also contain old hours, unclear text and services you no longer offer.
Treat the first result as a draft to review. A page that looks ready may still have wrong details or a form that needs setup. A clear fact sheet makes that review much easier.
The short answer
- Check what the tool can read before giving it your old website address.
- Approve the facts and image rights, then review each customer task on its own.
- Plan page redirects, customer records and connected tools as separate work.
How this guide was made
This guide draws on Google, MDN and W3C guidance about AI content, planning and basic access checks. The transfer table and window cleaning example are planning tools, not results from a live import test. A reference URL does not prove that a builder can move your data or connected services.
Sources checked .
Check what the builder can use
An AI website builder from a URL may read the public text, page layout or images. Ask which of these it uses. Also ask what happens if a page cannot be read. A preview alone will not tell you what was missed.
Content and style
Choose whether the old site is a source of facts, a visual reference or both. You may want to keep the service details but change the look. Say that in the brief. Remove old offers from the approved facts before you begin.
A design reference from another business can show the type of layout you like. It does not give you permission to copy its words or images.
Forms and connected tools
Make a list of bookings, payments, member accounts and other tools you use. Ask the builder to explain how each will work on the new site. A button that looks the same may lead to a different system.
If the tool cannot show how a required task will work, resolve that gap before paying for the move. Customer records and passwords should not be pasted into an AI prompt.
What can move from an existing website
Use this inventory to agree the scope with your builder. These are questions to check, not a list of features every AI tool offers.
| Item | Evidence needed | Decision before launch |
|---|---|---|
| Service copy | Current facts approved by the owner | Reuse, correct or remove |
| Images | Original file and permission to use it | Keep a suitable image or replace it |
| Page addresses | List of old URLs and proposed destinations | Keep the URL or map its move |
| Contact forms | Field list, saved test request and receiving inbox | Set up and test the full path |
| Customer data and logins | Separate transfer plan with access controls | Confirm who moves and checks them |
| Booking or other tools | Supported connection and a completed test task | Keep, replace or leave out with approval |
Build a short fact sheet
Start with the business name, services, area, opening hours and contact details. Add the one action you want a visitor to take. Give each fact an owner and an approval date.
Gather the logo and images you may use. MDN explains that planning includes the purpose, content and design, and that images and fonts can have use restrictions. Save the permission record with the asset.
Mark an unknown price or service limit as an open question. Ask the owner to answer it before launch. Do not let the draft fill the gap with a guess.

Turn old content into approved content
Here is a fictional window cleaning business. The example shows how to review facts before building. It does not describe a real customer or a measured result.
Notice that the approved column does not try to preserve every old sentence. It keeps useful information, corrects facts and gives the draft a clear job.
| Old content | Approved direction | Draft check |
|---|---|---|
| Quality solutions for everyone | Explain home window cleaning in plain words | Reader can name the service |
| An old phone number | Use the number confirmed by the owner | Visible number and phone link match |
| A broad service area claim | List only areas the team serves | No extra towns appear |
| Outdated opening hours | Use the current approved schedule | Hours match on every page |
| An image copied from elsewhere | Use an owned or permitted image | Image fits the service and its use is allowed |
Use this short AI brief
Copy these instructions into your brief and replace the bracketed text. Add your fact sheet and transfer inventory. Keep each instruction short so you can check the draft against it.
| Part | Prompt to adapt |
|---|---|
| Business | Create a website draft for [name]. We help [customers] with [services] in [area]. |
| Goal | The main visitor action is [request a quote, call or another task]. Explain what happens after it. |
| Reference | Use [URL] for [approved facts, layout ideas or both]. Change [parts that no longer work]. |
| Content | Build [page list]. Use only the approved facts. Mark missing answers for review. |
| Proof | Do not invent prices, reviews, awards, staff, qualifications or locations. Use approved images. |
| Functions | Include [required tasks]. List any connected tools or forms that still need setup and testing. |
Review facts and functions separately
Review the facts first, then try the actions. Keep a short issue list with the page, what is wrong and who will fix it.
Facts and images
Compare names, prices, hours and service limits with the approved sheet. Check the page title and description too. Google advises checking AI output for accuracy and quality, including these page details.
Look at what each image suggests. A made up office or team photo could give a false impression of your business. Use a real approved photo when the image is meant to show your people or place.

Links and customer actions
Follow the main contact route on a phone and a computer. For a form, check the saved inquiry and the intended inbox. A success message on the page is not proof that the email arrived.
Use a keyboard to reach menus and fields. W3C offers basic checks for headings, labels and access. They can find some problems, but they do not replace a full accessibility review.

A worked review example
Imagine the fictional window cleaner in the earlier table is ready to launch. The owner uses the following checks. This is a sample review record, not a test carried out on a customer site.
| Check | Evidence to compare | Pass rule |
|---|---|---|
| Opening hours | Draft against the dated owner fact sheet | The old closing time has been corrected everywhere |
| Quote form | Marked test in saved requests and the approved inbox | Details match, and the reply goes to the test sender |
| Old service link | Old URL against the move plan | It opens the right new service page |
| Missing price | Page against the open questions list | Owner supplies a price or explains how quotes work |
Keep the move and launch as separate jobs
Keep access to the old site while you review the replacement. Set a person and date for domain setup, changed page addresses and final checks. These jobs are easy to miss when the preview looks finished.
SnapRebuild offers an optional reference URL and a preview to review. Use the preview to judge the draft against your brief. Confirm any essential connected tool before you choose a plan.
Publish only when the required facts and customer tasks pass your checks. Save the issue list and move plan for whoever looks after the new site.
