Where to use itWeb, iOS, Android and desktop app for Windows and macOS.Web, iOS, Android, Windows and macOS; Claude Code and an API for developers.
Pros
  • The Swiss Army knife of AI: writes, summarises, translates, codes, analyses files, searches the web, talks by voice and creates images in one window.
  • Interactive answers with GPT-6: charts, comparisons, maps or calculators inside the chat.
  • ChatGPT Work and Codex work for hours on complex tasks and hand back the finished result.
  • Generous free plan (GPT-6 Luna, no fixed cap on text chats) and a huge ecosystem of GPTs and connectors.
  • Writes in a natural style and follows tone and format instructions well.
  • Very strong at coding with Claude Code, which completes whole tasks on a project.
  • Handles long documents well (1M-token context on the 5.5 models).
  • Artifacts turn a request into a web page, chart or tool you can share.
Cons
  • Ads on the Free and Go plans in Spain; removing them means upgrading to Plus.
  • Privacy could be better: training on by default and a €15 million fine in Italy (2024).
  • Confusing line-up: model names that change every few months and three Pro plans, the top one above €500 a month.
  • Allowances run out in intense sessions, with five-hour and weekly windows.
  • No image or video generator of its own.
  • Training on by default for personal accounts (data kept up to 5 years unless you opt out).
Use cases
  • Anyone who wants a single assistant for everything (studying, writing, getting organised); professionals and freelancers who want to delegate reports, slides or spreadsheets; developers (with Codex).
  • For long jobs, such as a report with its spreadsheet and slide deck, use ChatGPT Work in the desktop app (also on the free plan, with limits). For personal matters, open a temporary chat: it is not used for training and is deleted after 30 days.
  • Writing and editing; coding and automation; analysing long documents; building mini-apps without coding.
  • Before a long job, create a Project with your documents and standing instructions (tone, format, audience): you won’t have to repeat them in every chat and you’ll use less of your allowance.
