Claude is the assistant from Anthropic, a company founded in 2021 by former OpenAI staff. It chats, writes, summarises, analyses documents and spreadsheets and codes, and has won its place above all among heavy writers and developers.
Its strengths are writing quality and handling long documents, plus “artifacts” (mini-apps, web pages or documents in a side panel) and Claude Code, one of the most widely used AI coding tools. Its weakness: it focuses on text and code, with no image or video generator of its own.
It might suit you if…
Writing and editing; coding and automation; analysing long documents; building mini-apps without coding.
Try a concrete use case.
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.
What to check.
Usage limits are noticeable even on paid plans. List prices are in dollars and exclude VAT. On personal accounts, training on your chats is on unless you switch it off.
Why this tier
The undisputed leader in code quality, natural cliché-free writing and understanding of long documents.
Pros and cons
Pros
- 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
- 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).
