Websites at the speed of marketing
Subtext is the website platform built for AI. Launch pages, update anything and ship new ideas with the AI you already use.
Works with Claude, ChatGPT and whatever comes next.
Skip the CMS.
Tell your AI what you want. A new blog post, a landing page for next week's webinar, three versions of the hero to choose from. It makes the change, you see it in a preview, and you publish when it's right. There's no feature to wait for.
If you can describe it, your AI can build it.
It works because websites are made of HTML, CSS and JavaScript, the code AI writes best. Page builders make your AI translate everything into their own format first, and a lot gets lost in translation. On Subtext, your AI works on the real site.
And it sees your whole site every time. Your layouts, your components, your colors, your tone. So every new page looks like it belongs.
Idea at breakfast. Live by lunch.
- New pricing page
- Series A funding announcement
- Refresh the homepage hero
- Case study from Tuesday's call
- German version of the site
Break your site in private.
Every idea starts in a Prism: a private copy of your site that updates the moment your AI makes a change.
Try anything.
Change your mind, try three versions, start over, translate the whole site to German. Nothing in a Prism touches your live site.
Comment on the page.
Click anything and leave a note for your AI, the way you'd mark up a draft. Share the link and your team can do the same, on the real page.
Publish in one click.
When it's right, it's live. Nothing goes out until you say so, and your site changes on your schedule, not anyone else's.
Roll back anything.
Every published change is saved, so nothing is permanent. Want last week's homepage back? That's one click.
Anything the web can do.
Page builders give you their features and their templates. On Subtext, your AI works with the same tools every developer uses, so your site can do anything the web can.
Go past the template.
Interactive demos, calculators, animations, a pricing page that works the way you picture it. No plugin to find, no feature to request.
Connect it to your work.
If your AI can read your call notes, docs and product updates, it can turn them into pages. "Turn this morning's customer call into a case study" is one request.
Build on something that lasts.
Every Subtext site is a standard Astro site, built with HTML, CSS and JavaScript. Any developer can pick it up, any AI can work on it, and you can download and move hosts anytime.
The boring stuff, handled.
Hosted on Cloudflare.
The network behind over 40% of the web's top sites. If it goes down, you'll have plenty of company.
Undo anything.
Every change is saved, and anything can be rolled back. Nothing you publish is permanent, so there's no reason not to try it.
Fast everywhere.
Fast pages for visitors anywhere in the world, which is good for search rankings and conversion.
Secure by default.
SSL on every page and protection against attacks. No plugins to patch, no database to breach.
SEO done right.
Page titles, descriptions, redirects, sitemaps. Everything you need to stay ranked.
Yours to keep.
Your whole site is yours to take anywhere, and any developer can pick it up.
Bring your site with you.
Point your AI at your current site and it rebuilds it on Subtext. Same design, same pages, same URLs. Connect your domain and your search rankings come with you. The work your designer put in is what keeps your AI on brand from here on.
Subtext walks you and your AI through the move, step by step.
