The short version

  • Only Grammarly has a free tier, so it costs nothing to try first.
  • Each has a real cost: Grammarly occasional false positives and grammatically incorrect suggestions that can introduce errors; HelpDocs it is a knowledge base only, so a company still needs a separate ticketing or chat tool for any support that is not fully self-service
  • They diverge on capability: Grammarly covers Grammar checking, HelpDocs covers Editor-only seat pricing.
  • Prices and features above were last checked on 1 September 2026.

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

HelpDocs

  • It is a knowledge base only, so a company still needs a separate ticketing or chat tool for any support that is not fully self-service
  • Extra editor seats above a plan's included count cost $25 each per month, which adds up quickly for a growing content team on the Harvest tier
  • AI credits are capped per plan and reset monthly, so a heavy AI-drafting workflow can exhaust the allowance before the billing period ends
  • Moving from Sprout to Bloom to add editors is a large jump in absolute price, not a smooth per-seat increment, since each tier is a fixed bundle rather than pay-per-seat
  • There is no free tier, only a 14-day trial, so a small team wanting to test long-term usage patterns has a short evaluation window
  • Being editor-priced means it does not scale cost with help centre traffic or ticket deflection value delivered, so a high-traffic help site pays the same as a low-traffic one with the same editor count
