  • They diverge on capability: Grammarly covers Grammar checking, Paligo covers Topic-based reuse.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Grammarly

  • Occasional false positives and grammatically incorrect suggestions that can introduce errors
  • Privacy concerns about sending text to Grammarly's servers for analysis
  • AI capabilities sometimes produce hallucinations and fabricated citations that appear grammatically correct

Paligo

  • The Business plan starts at $15,000/year for only two authors, which is a high price floor compared with help-centre or wiki tools and prices out small documentation teams
  • Topic-based, structured authoring has a real learning curve for writers used to free-form documents or Markdown, and onboarding time should be budgeted separately from the licence
  • Nexus Portal and Nexus Answers are separate paid products, so a buyer wanting hosted delivery or AI answers on top of authoring should expect additional annual cost beyond the base plan
  • Storage is capped per author (10 GB on Business) with additional storage or authors priced as add-ons, so a growing team's costs are not fully captured by the headline per-author price
  • Unlimited languages are only included on the Enterprise plan; Business is capped at two languages, which limits it for teams with more than a couple of target markets
  • Migrating an existing large documentation set into Paligo's structured content model is a real project, not a data import, and that migration cost sits outside the subscription price
