Where Semji falls short

  • No topical-map planning across a whole site
  • Limited writing — mainly an optimization and measurement layer
  • No hosting

Where Slate falls short

  • Workflow and governance tooling assumes you already have (or will build) a publishing pipeline and CMS
  • Content is produced through configurable workflows you set up, not a pre-built topical map
  • No hosting — publishes into your own CMS, not on a domain Slate manages

Or skip choosing between two point solutions.

Planning, writing, interlinking, and hosting — one system, $99/mo, one domain.
