Overview

Technical books go out of date fast. ChapterLens scans every factual claim in a chapter, flags what's stale and researches what's true today.

Authors stay in control: every proposed change comes with cited sources, can be approved, edited or rejected, and is rewritten to match their own voice.

What I built

  1. 01Drag-and-drop DOCX upload up to 50 MB — text, figures, tables and equations extracted instantly.
  2. 02GPT-4o scans every factual claim, flags outdated content and profiles the author's writing style.
  3. 03Automated web research pulls current data from government, academic and technical sources, cited per claim.
  4. 04Side-by-side review of original vs. updated text — approve, edit or reject each change.
  5. 05Style-matched rewrites that keep the author's tone, grade level and sentence structure.
  6. 06Exports an updated DOCX, a highlighted DOCX, PDF previews, a CSV changelog and a full audit trail.
