Your AI can build your site. It just didn't know it yet.

Sum is a set of solid blocks that Claude or ChatGPT put together for you, and that a real developer can pick up when you want something custom. No AI? Use ours.

One conversation, one site online

Make me a site for my garage in Terrebonne: Garage Tremblay, 450 555-0199. Maintenance, brakes, tires.

I'll start from Sum's garage example and fill it with your info.

  1. list_kitspicks the garage kit
  2. create_sitestarts from the example site
  3. write_blockyour name, services, hours
  4. check_sitereads it all back: nothing's off
  5. publish_siteputs the site online

index = entete | enseigne, services, tarifs | pied

Your site is live. You can send the link to your mom.

How it works (short version)

With your AI or ours, same path. And it's short.

  1. Describe your business

    Your name, what you do, where to find you, photos if you have any. If you can write a text message, you can do this step.

  2. See your site online

    A few minutes later, at a temporary address. No account needed to look.

  3. Keep it, change it

    Your email is enough to claim it. Then ask for changes in a chat, edit the text right on the page, or hand it to a human.

Built for AI, clumsiness included

Your AI is brilliant, but we don't let it touch the code. A Sum page is written as a formula of proven blocks: the AI picks the blocks and fills them in. It can't break the layout, not even on a Friday night.

index   = entete | enseigne, tarifs | pied
contact = index - tarifs + rendezvous
The contact page takes the home page, drops the prices and adds the appointment form.
Blocks that say what they want
Every block describes its fields: required, lengths, allowed values. The AI knows what to write, and Sum refuses the rest.
Errors that help
A title too long? Sum tells your AI before your customers notice. It fixes it, then publishes.
A standard connector
Sum connects through MCP, the protocol Claude, ChatGPT and other agents use to work with tools. Nothing exotic.
Nothing locked in
A Sum site is plain, readable files: structure, content, theme. No black box: a developer can always pick them up.

One site, one conversation

This garage site was created, filled in and published by an AI, using only Sum's tools. The mechanic didn't install anything. He doesn't exist either, but that's a detail.

The top of the Garage Tremblay website: the headline “Your trusted garage in Terrebonne”, with buttons to call and book an appointment
Garage Tremblay, a fictional garage: site created, filled in and published by an AI in eight calls to Sum's tools.

Your AI starts. A human can finish.

Sum isn't just vibe coding. A Sum site is readable files, not a black box. When you want a touch that's truly yours, a developer picks up exactly where your AI left off.

Talk to a human

Your software offers websites. Sum does the rest.
