IATO vs Slickplan

At a glance

Slickplan is a dedicated sitemap planning tool used by web designers and UX teams. It offers a clean visual editor for creating sitemaps from scratch, content planning features, and team collaboration. However, it cannot crawl existing websites.

IATO combines website crawling (up to 250,000 pages) with a visual sitemap editor powered by AI. Instead of building sitemaps from scratch, IATO crawls your existing site, generates the sitemap automatically, and lets you restructure it with drag-and-drop editing and AI assistance.

Where Slickplan excels

Purpose-built sitemap design. Slickplan is laser-focused on visual sitemap creation. Its editor is polished and intuitive, with features like content blocks, design mockup integration, and multiple export formats (PDF, XML, text). It's trusted by agencies like National Geographic, Google, and Samsung for IA planning.

Diagram-first workflow. If you're designing a new website from scratch (before any pages exist), Slickplan's blank-canvas approach is ideal. You can plan the entire structure visually, add content notes, and share with stakeholders.

Where IATO is different

Crawl-first, then plan. Slickplan requires you to build sitemaps manually. IATO crawls your existing site and generates the sitemap automatically. This means you start with reality — actual URLs, page titles, word counts, and link structures — rather than a blank canvas.

SEO intelligence. Because IATO crawls your site, it knows about broken links, duplicate titles, thin content, redirect chains, and 50+ other SEO issues. Slickplan has no crawling capability and therefore no SEO analysis.

AI-powered restructuring. IATO's AI can analyze your site structure and suggest improvements. Tell it to "flatten the blog hierarchy to two levels" or "merge the support and help sections," and it restructures the sitemap for you. Slickplan has no AI features.

Developer platform. IATO's 440+ API endpoints, TypeScript SDK, and MCP server make it possible to automate sitemap generation, content classification, and SEO auditing programmatically. Slickplan offers no API.
