Every AI tool has a sweet spot. The mistake is using the wrong one. After two years of building sites with all three, here is the breakdown of which tool I reach for when.
Manus: layout and structure
Manus is my first stop for any new site build. It is the best tool I have found for generating complete page layouts from a brief — not just a single page, but the structural logic across the whole site.
Where it shines: full-page mockups, multi-page site consistency, deciding what goes in the hero versus footer, generating the navigation IA. The output is a coherent site draft, not a random page.
Where it falls short: it cannot do code, it cannot do detailed copy edits, and it does not generate original imagery. It is a layout tool, not a build tool.
Claude Code: code, logic, and long-context work
For anything that requires actual code — custom WordPress functionality, JavaScript interactions, PHP for forms, batch scripts, cron jobs — Claude Code is what I reach for. Same for refactoring existing code and writing long technical documents.
Where it shines: complex multi-file changes, code that needs to integrate with WordPress hook system, anything requiring me to look at a 50-file codebase.
Where it falls short: it is not visual. If I need to design a layout or generate copy, I switch tools.
Midjourney: imagery that does not look generic
For hero images, blog post thumbnails, illustration sets, and any imagery that needs to feel distinctive rather than templated, Midjourney is the best tool I have used. The output has more personality than stock photo selections and is faster than commissioning originals.
Where it shines: distinctive imagery, illustrations, abstract backgrounds, anything that needs to feel hand-made.
Where it falls short: not for product photography (use real photos), not for faces in commercial contexts (legal and ethical concerns), and not for content that needs to match a specific real-world reference.
What I do not reach for
One-click AI site builders like Durable, Mixo, 10Web. They generate sites but the output is hard to edit, the templates are visible from a mile away, and you cannot move the result into a normal WordPress install without rebuilding it. Better to use Manus and a clean theme than a one-click builder.
The actual rule
Layouts go to Manus. Code goes to Claude. Imagery goes to Midjourney. Copy gets drafted by ChatGPT and rewritten by hand. Each tool does one thing well. Mixing them up produces mediocre output everywhere.
