A custom instructions prompt that cuts ChatGPT's verbose answers down to size
Rare_Guide_9830 · reddit · 2026-09-20
A Reddit user shared a set of custom instructions for ChatGPT (Settings > Personalization > Custom Instructions) to force extremely concise responses.
Key rules: answer first, default to 1–3 short paragraphs or bullets, never restate the question, skip intros/summaries/obvious background, prioritize the 20% of information with 80% of the value, offer the best few options instead of all of them, and never pad answers to seem comprehensive — if 100 words beats 500, use 100.
