What is in this section?
Overview pages for widely used AI assistants and tools: what they do, where they stand out, how free and paid access is generally structured, and what to watch out for. Plan and access details are written with the date they were checked and links to official sources. Because these details change, check the product's own website before you subscribe.
When using AI tools
- Do not type ID numbers, passwords, bank details or confidential work information into chat tools.
- Always check figures, dates, names and sources; these tools can state wrong information confidently.
- Try the free version on your own work before moving to a paid plan.
- If you work with company data, use the tools your employer allows.

Which tool should you pick?
There is no single "best" AI tool; the right one depends on what you do. If you work with long documents, an assistant that handles long texts well fits better; if you want current information, a search tool that cites sources; if you write code, a tool that plugs into your development environment. Asking two tools the same question and comparing the answers is the quickest way to see which suits you.
