How we compiled this
Self-serve USD pricing for 8 leading grammar-checker vendors was collected by fetching each vendor's official pricing page on 2026-06-15. Where the live page rendered a non-USD currency or failed (403/JS-only), the figure was sourced from a reputable 2025/2026 comparison page (fixthephoto.com/best-grammar-checker.html, slashdot.org software profiles, getapp.com, sourceforge.net) and flagged in provenance. monthlyUsd records the effective monthly cost at the smallest self-serve unit: for annual plans this is the annualised monthly equivalent (annual total ÷ 12). Quote-only / contact-sales tiers carry monthlyUsd=null. minutesIncluded, callsIncluded, overagePerMin, overagePerCall are null on every plan (non-telephony). hipaa/baa/bilingual are null unless the vendor explicitly states otherwise on their public site.
