The Detail

Why ChilledSites Wins

Five core reasons modern AI wins over a legacy assistant system.

Modern Claude AI vs Aging AIDA

AIDA launched in 2017 — before GPT-3 existed. ChilledSites uses Claude, one of today's most capable AI models. The output quality gap is enormous: unique designs, real business copy, clean code.

60 Seconds, Not 10 Minutes

AIDA walks you through a series of questions before building. ChilledSites needs one sentence. Type what your business does, click Generate, and your site is live in under a minute.

Unique Designs, Not Templates

AIDA picks from a library of templates and customises them. ChilledSites generates unique HTML and CSS for every single site — no two sites look the same, and yours won't look like everyone else's.

£29/Year All-In

Bookmark's mid-range plan costs around $15–25/month — roughly $180–$300 a year. ChilledSites Pro is £29/year with hosting, SSL, a custom domain, contact forms, and AI edits all included.

AI Editing, Not Drag-and-Drop

When you want to change your headline or add a new section, you don't drag boxes around. You just describe the change in plain English and the AI rewrites it. Editing a website has never been this fast.

Everything Included, No Surprises

ChilledSites has transparent annual pricing. No upsells for forms. No extra charge for SSL. No hidden hosting fee. The price you see is everything you need to have a live professional website.

FAQ

Common Questions

Everything you want to know about Bookmark AIDA vs ChilledSites, answered honestly.

Bookmark AIDA (Artificial Intelligence Design Assistant) is a website builder that launched around 2017. It was one of the first AI-powered website creation tools — a genuinely pioneering product for its time. AIDA uses a conversational approach, asking you questions about your business and goals, then assembling a website from a library of templates and pre-built sections. While innovative in 2017, the underlying technology is considerably older than modern AI platforms that use frontier large language models like Claude or GPT-4.
The fundamental difference is AI generation depth. Bookmark AIDA picks and personalises a template — the structure, layout and component library are pre-built. ChilledSites uses Claude to write completely new HTML, CSS, and content from scratch for every site. The output is uniquely generated, not assembled from parts. ChilledSites is also dramatically faster (60 seconds vs several minutes of Q&A) and significantly cheaper (£29/year vs $144+/year for Bookmark's paid plans).
Bookmark was genuinely impressive when it launched in 2017 — AIDA was ahead of its time. But AI has advanced dramatically. Modern platforms use frontier models that were trained on vast amounts of design, code, and copy — producing outputs that AIDA simply can't match in quality or originality. If you're comparing in 2026, you're essentially choosing between 2017-era AI and 2025-era AI. The gap is substantial. For most users starting fresh, a modern platform like ChilledSites will deliver better results faster and more cheaply.
Bookmark's paid plans run approximately $12–$25/month when billed annually — that works out to $144–$300 per year. ChilledSites starts at £29/year (roughly $37/year), which includes AI generation, hosting, SSL, a custom domain connection, contact forms, and unlimited AI edits. That's a 4x to 8x price difference on an annual basis, with ChilledSites including everything you need to have a live professional website at no extra cost.
ChilledSites is significantly faster. You describe your business in a single sentence — "I run a dog grooming salon in Brighton" — hit Generate, and your complete website is ready in under 60 seconds. Bookmark AIDA uses a back-and-forth questionnaire that asks about your industry, business type, target audience, preferred style, and more before presenting a result. This typically takes several minutes of interaction even before you see a site.
Yes, and editing is one of ChilledSites' strengths. The built-in AI editor lets you click any section of your page and describe what you want to change — "make the headline more direct" or "add a testimonials section below the pricing" — and the AI rewrites just that part instantly. You can also regenerate your entire site from a revised prompt at any time. Bookmark uses a traditional drag-and-drop editor for post-generation changes, which requires more manual time and effort.
Yes — all ChilledSites plans include fast global hosting, automatic SSL, and a free chilledsites.com subdomain. You can also connect your own custom domain. There are no separate hosting charges — everything is included in the £29/year price. Bookmark includes hosting on its paid plans, but the pricing is structured monthly, making it considerably more expensive over the course of a year.
