Gemini vs ChatGPT: Which Should You Use? (2026)
Gemini is Google's AI assistant and ChatGPT is OpenAI's. Both can write, summarise, explain, analyse files and search the web. Gemini is convenient if you already live in Google's apps such as Gmail, Docs and Drive, while ChatGPT is a broad all-rounder many people use for drafting, analysis and long conversations. Both have free plans with limits, and both can be wrong, so test the same tasks in each and verify important facts.
Gemini and ChatGPT are two of the most used AI assistants. Features, models and plans change often, so this guide focuses on how to choose rather than on a feature race. Confirm current details on each company's own pages.
