Make a long document skimmable with canvas
Task · Structure & readability
Time saved · 20-30 min per document (estimate, not measured)
Steps
- Open ChatGPT and paste or upload the document
- Ask ChatGPT to open it in canvas (or pick canvas from the tools menu)
- Run the prompt below
- Use canvas's inline edits to tweak sections, then copy it back to your doc
Prompt / template
Restructure this document so a busy reader can skim it in 60 seconds: add a 3-line TL;DR at the top, short descriptive headings, paragraphs of 2-4 sentences, and a bulleted list only where items are truly parallel. Don't change the content or add new claims. Highlight any section that's still hard to follow.
