Frequently Asked Questions: Grammarly vs Proof&Trust
Grammarly has 58,867,412 monthly visits, while Proof&Trust has 0. Traffic estimates describe audience size, not product quality.
Consolidating Premium and Business into Grammarly Pro ($12/member/month annual) gives individuals and small teams access to style guides, analytics, and plagiarism/AI detection in one plan.

Limitations
–Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).
–Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.
–Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.
Proof&Trust
Score every vendor, tier every risk, and prove it to your NIS2 auditor
Evidence ingestion and validation
Connects contracts, vendor masters and document stores, then verifies the authenticity, validity and scope of certificates, attestations, SBOMs, pen-test reports and policies.
Artifact and vendor scoring
Scores each artifact on completeness, recency, source trust and control coverage, then rolls the results into a continuously recalculated vendor risk index.
Continuous NIS2 tiering
Auto-classifies vendors into critical, important and baseline tiers by dependency, concentration and evidence quality, re-tiering the moment evidence changes.
Audit-ready reporting
Produces cited, exportable evidence trails mapped to all ten NIS2 Article 21(2) measures, plus Article 23 incident-notification drafting with 24-hour early-warning timing.
Strengths & Pros
+Published euro pricing makes budgeting straightforward, unlike many compliance platforms
+Continuous scoring and re-tiering beats an annual questionnaire snapshot when risk changes mid-year
+No integration is required to get a first scored portfolio, and a free sample assessment lowers the trial risk
+
EU-hosted with data residency and explicit mapping to all ten NIS2 Article 21(2) measures
Limitations
–Focused squarely on NIS2, so organisations outside its scope get less out of the tiering model
–Assessment caps per tier (20/100/300) mean very large vendor estates need a custom quote
–It is a newer platform, so it lacks the long public track record of established GRC suites
