# Grammarly Cost Tuning ## Overview Grammarly enterprise pricing is per-seat with API costs driven by text check request volume and document length. Each grammar check, tone analysis, and plagiarism scan consumes API quota proportional to word count. For organizations processing thousands of documents daily, unchecked API usage — especially on long documents or duplicate content — creates substantial cost overrun. Implementing validation gates, result caching, and sample-based scoring reduces API spend by 40-60% without sacrificing quality coverage. ## Cost Breakdown | Component | Cost Driver | Optimization | |-----------|------------|--------------| | Seat licenses | Per-user/month enterprise pricing | Audit active seats quarterly; remove inactive users | | Text check requests | Per-call API quota on grammar/tone checks | Cache results for identical text; deduplicate requests | | Document length | API cost scales with word count per request | Chunk documents over 10K words; skip boilerplate sections | | Plagiarism scans | Higher-cost endpoint for originality checks | Run only on final drafts, not every revision | | AI rewrite suggestions | Premium feature with per-request cost | Batch rewrites; limit to flagged passages only | ## API Call Reduction ```typescript class GrammarlyCostGate { private resultCache = new Map<string, any>(); shouldCheck(text: string): boolean { const words = text.split(/\s+/).length; return words >= 30 && words <= 50_000; // Skip t...
