WriteTrack Documentation

WriteTrack is a TypeScript SDK for capturing and analysing writing sessions at the point of entry. It records timing, rhythm, corrections, and clipboard interactions from text input elements. summarizeAnalysis() derives fields such as effort ratio, pasted share, largest paste, and correction count for storage and review interfaces.

Key Features

Section titled “Key Features”
  • Analysis summaries — summarizeAnalysis() derives effort ratio, paste share, largest paste, and correction fields using the same calculation as the scorecard
  • 100% Client-side SDK — When embedded in your app, the SDK does all capture and analysis in the browser; no data is sent anywhere unless you configure output sinks. (The WriteTracker demo app is opt-in — see Privacy.)
  • Framework agnostic — Works with vanilla JS, React, Vue, Svelte, or any frontend framework
  • Zero runtime dependencies — nothing is pulled into your dependency tree by installing WriteTrack
  • Detailed Behavioural Data — Captures timing, rhythm, corrections, clipboard usage, and more

How It Works

Section titled “How It Works”

WriteTrack instruments text inputs, captures behavioral signals, and analyses the resulting session:

  1. Capture — Timing (dwell, flight, rhythm), corrections (backspaces, deletions, revisions), clipboard interactions (paste, copy/cut, selection), and session dynamics (bursts, pauses, fatigue)
  2. Analysis — WASM-powered analysis scores the session across seven categories: content origin, timing authenticity, session continuity, physical plausibility, revision behavior, temporal patterns, and writing process
  3. Summary — summarizeAnalysis() derives fields for storage and queries
