ChatGPT

ChatGPT is OpenAI’s conversational assistant. You type or speak a request and it answers, drafts, summarises, writes code, reads uploaded files, searches the web and generates images, all in one chat window. Conversations sync across the web app, desktop apps for Mac and Windows, and the phone apps.

It is a sensible default for people who want one tool for a wide spread of everyday tasks: drafting emails, brainstorming, explaining a topic, working through a spreadsheet or tidying up a piece of writing. Custom GPTs and projects let you keep instructions and reference files together for recurring work.

The free plan gives limited access to OpenAI’s models. Paid individual tiers (Go, Plus and Pro) raise usage limits and unlock newer models and features, and Business and Enterprise plans add admin controls. Prices vary by country, so check the pricing page for your region.
