AI blog website builder
A website with a blog that writes itself.
Ostra generates your whole site — and its blog. Ask for a post in plain English (“write a post announcing our fall collection”) and the AI drafts it, finds a photo, and publishes it to your feed with search-engine structured data built in.

Posts written on request
Tell the chat what to write — a launch announcement, a how-to, a local guide targeting a keyword — and a real post appears on your blog with a fitting photo. You edit any line by asking.
SEO and AI-visibility baked in
Every page ships with editable titles and descriptions, and your site emits structured data (business info, products, FAQs, posts) that search engines and AI assistants read.
It's a full business site, not just a blog
Lead forms, online booking, even a shop with Stripe checkout — the blog is one page of a complete system, all edited through the same AI chat.
Real sites, built from one sentence
Click through — these are live, generated and published entirely with Ostra.
How it works
Watch a business become a website.
No templates to pick, no builder to learn. Describe the business and the site assembles itself — design, copy, and conversion path chosen for you. Don't like the look? Remix it.

Common questions
Does the AI really write the posts?
Yes — you ask in plain English and it drafts a genuinely useful post (300–600 words), finds a matching photo, and publishes to your blog. You can rewrite any part by asking.
Is the content good for SEO?
Posts target the keyword you ask for naturally, every page has editable meta titles/descriptions, and the site emits BlogPosting, FAQ, and business structured data automatically.
Can I write posts myself?
Of course — the Content editor lets you hand-edit anything, and uploads replace any photo.
What does it cost?
Free to generate and preview. Going live starts at $29/mo; AI writing uses credits included with every plan.
