| 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.
| - 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.
|
|---|
| 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).
| - 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.
|

| 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.
| - 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.

| Privacy and data | Turn off training in Settings > Data controls > “Improve the model for everyone”. Temporary chats are deleted after 30 days. On ad-supported plans, ads may use the conversation context; OpenAI says it does not sell your data. | On personal accounts (Free, Pro, Max and Ultra) training on your conversations is on: if you leave it, Anthropic may keep them for up to 5 years; if you turn it off in Settings > Privacy, they are deleted in about 30 days. Business plans and the API are not used for training. | With “Keep activity” on, your chats may be used to improve the models and some are reviewed by people (kept for up to three years). Turn it off at myactivity.google.com or use temporary chats. Google says it does not use your conversations for ads. |
