ChatGPT

ChatGPT is a chat assistant made by OpenAI. People type or speak a question and get an answer in plain language. It can write and edit text, explain topics, summarize documents, help with code and solve maths problems. OpenAI released it to the public in November 2022.

The app runs on OpenAI's GPT models. It can search the web, read uploaded files and images, create images and hold voice conversations. Users can also build custom versions called GPTs for set tasks. It is available on the web, on iOS and Android, and as desktop apps for Mac and Windows.

There is a free plan with usage limits. Paid plans such as Plus and Pro raise those limits and add newer models and features. Team, Enterprise and Edu plans add admin controls and data protections for organisations. Students, office workers, developers and small businesses all use it, and many companies build on the same models through the OpenAI API. OpenAI is based in San Francisco.
