Frequently asked questions
How much does Claude Pro cost?
Claude Pro costs $20/month (approximately €18.50). It offers priority model access, 5x higher usage limits than the free tier, and access to the latest models like Claude Opus. With the referral, you get 1 free week to try it.
What's the difference between Claude and ChatGPT?
Claude (Anthropic) and ChatGPT (OpenAI) are competing AI assistants. Claude stands out for more nuanced reasoning, a larger context window (ideal for long documents) and a safety-first approach. ChatGPT offers a wider plugin ecosystem and real-time internet access. Choose based on your needs: Claude for deep analysis and writing, ChatGPT for versatility and integrations.
Does Claude referral work in all countries?
Yes, Claude is available in most countries worldwide. The referral link works wherever Claude is accessible. The subscription is billed in US dollars.
What Claude models are available?
Claude offers three model families: Opus (most powerful, ideal for complex reasoning and analysis), Sonnet (excellent balance between performance and speed) and Haiku (fastest, suited for simple tasks and high volumes). With Pro, you get priority access to the latest versions of each model.
Can Claude analyse documents and images?
Yes, Claude is multimodal: it can analyse images, PDFs, text files and spreadsheets. You can upload a document directly into the conversation and ask questions about it. Claude excels at analysing long documents thanks to its extended context window (up to 200K tokens), making it ideal for report summarisation, contract analysis and code review.
What are Claude Code and Claude for Work?
Claude Code is a command-line tool that lets developers delegate coding tasks from their terminal. Claude for Work is Anthropic's enterprise offering: Claude Teams ($30/user/mo) and Claude Enterprise with admin, advanced security and professional tool integrations. The referral gives access to the individual Pro plan.
Is the free version of Claude sufficient?
The free Claude tier provides access to Sonnet with daily usage limits. It's sufficient for occasional use: a few questions per day, short document analysis, writing help. For intensive use (long work sessions, large documents, complex projects), Pro at $20/mo removes these limits and provides access to the most powerful models (Opus).
