Grammarly Observability

Overview

Grammarly API integrations process user text through scoring, AI rewriting, and plagiarism endpoints where latency and accuracy directly affect user experience. Monitor text check response times, suggestion quality signals, API error rates, and token consumption to stay within rate limits. Catching degradation early prevents users from seeing stale suggestions or silent failures in real-time editing flows.

Key Metrics

Metric	Type	Target	Alert Threshold
Text check latency p95	Histogram	< 300ms	> 800ms
API error rate	Gauge	< 1%	> 5%
Suggestion acceptance rate	Gauge	> 40%	< 20% (quality signal)
Token usage (daily)	Counter	< 80% quota	> 90% quota
Plagiarism check latency	Histogram	< 2s	> 5s
AI rewrite throughput	Counter	Stable	Drop > 30%

Instrumentation

async function trackGrammarlyCall(api: 'score' | 'ai' | 'plagiarism', textLen: number, fn: () => Promise<any>) {
  const start = Date.now();
  try {
    const result = await fn();
    metrics.histogram('grammarly.api.latency', Date.now() - start, { api });
    metrics.increment(, { api });
    metrics.(, textLen, { api });
     result;
  }  (err) {
    metrics.(, { api, : err. });
     err;
  }
}
