Where to use itWeb, Android and iOS; Gmail, Docs, Vids, AI Mode in Search and Gemini Notebook.Web, iOS, Android and desktop app for Windows and macOS.
Pros
  • Deep integration with Gmail, Docs, Drive, Search and Android.
  • Very strong at images and video: Nano Banana edits photos precisely and paid plans generate video (Omni Flash).
  • Gemini 4 Argon, a frontier model, on AI Pro and Ultra, with a one-million-token context.
  • Plans with lots of extras: AI Plus (€4.99) includes 400 GB and AI Pro adds 5 TB and YouTube Premium Lite.
  • 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.
Cons
  • The free plan has been cut back to Flash-Lite with vague limits.
  • Privacy: human reviewers and reviewed chats kept for up to three years.
  • Confusing branding and line-up, and new features reach the US before the European Economic Area.
  • 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.
Use cases
  • People who already live in Gmail, Drive, Docs and an Android phone; students and researchers working with many sources (Gemini Notebook); image and video creators.
  • Create a notebook with your PDFs, notes or links and ask questions only about those sources; in Gemini Notebook you can turn it into an audio overview to listen to in the car.
  • 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.
