Build and publish a website with an AI agent
A Monmo agent can build a website or landing page from a brief. It writes the copy, builds the page with MonstarX, the app builder included in the same subscription, checks the preview at phone, tablet and desktop widths, and fixes what it finds. You review the preview and ask for changes in plain words. Publishing is a separate step that waits for your approval.

How the agent does it
- 01
It reads the brief and your materials
Tell it what the page is for, who it is for and the one thing visitors should do. It reads the copy and photos you keep in Google Drive and the colours, type and layout in your Figma file.
- 02
It plans the page and writes the words
Before building, it sends a short plan: the sections in order, two headline options, the form fields and what happens after someone signs up. Changing the plan costs a sentence; changing a built page costs more.
- 03
It builds the page in MonstarX
With your approval it starts a project in MonstarX, the app builder that comes with the same subscription, and follows the build until a preview link is ready. The project stays in your MonstarX account.
- 04
It checks the preview at three sizes
The agent opens the preview in its own browser at phone, tablet and desktop widths. It clicks every link, submits the form with a test address, reads the text for errors and looks for anything cut off or overlapping.
- 05
It fixes what it finds
A typical find: on a 360-pixel phone the sign-up button covers the email field. The agent proposes the fix, sends it to the project once you allow it, then checks all three sizes again and shows you before and after.
- 06
You review and ask for changes
Open the preview on your own phone. Ask for changes the way you would ask a colleague: change the headline, move the form up, use the second photo. Each change is sent to the project and checked again.
- 07
It asks before publishing
A card names the address where the page will become public. Allow it and the page goes live; decline and nothing changes. The agent then opens the live page to confirm it loads and the form works.
What you end up with
- A published page at a public address, live only after you approve
- A preview link to open on your own phone before that
- A check report: what was tested at phone, tablet and desktop size, and what was fixed
- The project in your MonstarX account, where you or the agent can keep building it
When it asks you
Planning, writing and checking need no approval, but starting or changing a project in MonstarX asks first. Publishing is always its own card, naming the address that becomes public, and until you allow it the page is not published.
How to ask
- Build a launch page for Ridge with a waitlist form. Copy and photos are in the Drive folder Ridge launch, the design is in Figma. Check it at phone size and show me the preview before you publish.
- Change the headline to Hot till the summit, move the form above the photos and check the phone layout again.
- Our pricing page is in the GitHub repository fieldwork-site. Add the new Team plan, run the site on your computer to check it, and ask me before you push.

Questions people ask
Can an AI agent build a website?
Yes. A Monmo agent takes a brief, writes the copy, builds the page with MonstarX, tests the preview at phone, tablet and desktop sizes and fixes the problems it finds. You look at the preview, ask for changes in plain words and approve publishing. For a larger site, ask for one page or section at a time so each can be reviewed.
What is MonstarX, and does it cost extra?
MonstarX is the app builder that comes with Monmo. One subscription covers both. Each product has its own usage allowance, and a build counts toward the MonstarX one. You authorise the connection once, and the projects the agent builds sit in your MonstarX account, where you can open them yourself and keep building by chat.
Can it match our brand and design?
Yes, if you show it the design. The agent reads colours, fonts, spacing and layout from your Figma file, through the Figma connection or in its own browser, and takes logos and photos from Google Drive. After building, it compares the page with the design frame and lists the differences it could not close, so you can decide.
Does it really test the site on a phone?
It tests at phone size, not on a physical phone. The agent narrows its own browser to widths such as 360 and 390 pixels, looks for text that is cut off or buttons that overlap, and tries the form and every link. Before you approve publishing, open the preview on your own device as well; that is the last check.
Can it work on a website we already have?
Yes, when the code is somewhere it can reach. If your site lives in a GitHub repository, the agent can copy it to its own computer, make the change on a branch, run the site to check it and prepare a pull request. Pushing code asks first, and merging and deploying stay with your usual process.
