  • A documentation team that needs reviewer seats for subject matter experts without giving them full author licences, available on the Online plansnot Grammarly

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

MadCap Flare

  • Flare is now subscription-only at $3,150 per author per year; a buyer who previously owned a perpetual licence faces an ongoing cost that did not exist under the old purchase model
  • A 12-month commitment is required on Flare Online, so a team cannot trial the cloud tier month to month before committing budget
  • Pricing above the Desktop base tier is entirely quote-based for Online plans, so team and business-tier costs are not comparable across vendors without a sales call
  • The authoring model, while less rigid than a full CCMS, still requires writers to learn topic-based structuring, conditional tags and variables, which is a real ramp for staff used to Word or a wiki
  • Storage is capped per tier with paid add-ons in 10 GB increments, so a documentation set with heavy image or video assets can incur additional cost beyond the headline price
  • Windows-only desktop authoring limits teams that standardise on macOS or Linux to the browser-based Flare Online tier, which may not have full feature parity with desktop
