Stop saying 'Summarize': the 'Noise Cancellation' prompt that reads 50-page reports in 2 minutes

The poster argues that asking AI to 'Summarize this' is risky: the model paraphrases the author without your specific context or data points, showing its interpretation rather than the text. He switched to 'Subtractive Processing' — delete useless words instead of writing new ones — with a full 'Noise Cancellation' prompt:
- Task: run a 'Redaction Audit' — keep the original text but strip sentences containing anecdotes, adjective/adverb fluff, and repetitive phrasing
- Constraint: do NOT rewrite or summarize; output only sentences with hard data, dates, or actionable instructions
The result is a compressed version of the original document: the author's exact words (no hallucinations) at 70% reduced volume — like AI-done highlighting.
