What GPT-4o is good at

GPT-4o is good at rewriting messages, summarizing notes and explaining code basics. In our tests, GPT 4o turned a blunt trial notice into a warm email, split meeting notes into decisions and action items, and explained let and const with an example of each.

Rewrite for tone

Rewrite this message so it sounds warm but firm: We can’t extend your trial again. Upgrade or your data will be deleted on Friday.

Summarize a meeting

Summarize these notes into decisions and action items: We will launch on 3 March. Lee fixes the login bug by Friday. Budget review is postponed. Mia writes the release notes.

Explain code

Explain the difference between let and const in JavaScript, with one short example of each.

GPT 4o turned a two-sentence notice into a full email with placeholders, so trim it if you need something short. Three sample prompts tested live by Chandan Kumar on November 11, 2026. Answers are unedited and regenerated for every new model.
