AI chatbots compared: what each one is best at

General-purpose chatbots have converged on the basics: answering questions, drafting text and explaining code. The differences show up in long documents, tool use and tone.

If you work with long files, look at context window and how well the model keeps track of details deep in the document. For quick everyday questions, speed and a good mobile app matter more.

For writing, try the same prompt in two or three assistants and compare the first draft, not the best draft. The one that needs the least editing is your default.

Browse the Chatbots category to watch short demos of each assistant before choosing one.
