ChatGPT

Overview

A chat assistant from OpenAI that answers questions and writes text when you type a request in plain language. It can also look things up on the web, read files, and make images.

General use

People use it to draft emails and documents, summarize long material, brainstorm ideas, and get quick explanations. Teams also connect it to their own data to answer internal questions.

Insight

The default pick, and the one that packs the most extras into one place: image generation, voice, and data analysis without switching tools. It is weaker than Claude at long careful writing and at following exact instructions. Its behavior also shifts between model updates, so a prompt that worked last month can drift. Best for everyday tasks and quick image or data jobs, less so for work where tone and precision matter most.
