What's inside
Everything you need. Nothing you don't.
Seawatt 10 is the model we've been waiting for. It understands layout, hierarchy, typography and taste — not just text.
Real copy, not lorem
Headlines, taglines and product descriptions written for your business, in your tone of voice.
Responsive by default
Every layout is built mobile-first and adapts cleanly from a 360px phone to a 4K display.
One-click publish
Push to a custom domain in one click. SSL, CDN and image optimization are baked in — no DevOps required.
Your brand, learned
Feed Seawatt 10 your logo and colors once — every future site stays on-brand automatically.

Three steps. Zero code.

Describe your idea
Type one sentence about your business. Seawatt 10 fills in everything else — pages, sections, copy.

Refine in chat
Ask for changes in plain English. "Make the hero bolder" or "swap the palette to forest green" — it just does it.
- 03
