What the free versions do
Claude Free (€ 0 pro Monat) today includes chat on web, desktop and mobile, web search, file creation and memory across conversations. Grok Free (€ 0 pro Monat) offers real-time web and X search and a voice mode.
Providers do not state the free limits in numbers. Whoever uses AI a few times a week for a question or a translation gets by without paying; a paid plan mostly solves the limit running out in the middle of work.
The paid entry
ChatGPT Go (€ 7,13 pro Monat) is the cheapest paid ChatGPT and contains ads. ChatGPT Plus (€ 17,82 pro Monat) adds the GPT-6.1 Sol model, the Work agent and Codex, without ads. Claude Pro (€ 18 pro Monat) adds Claude Code, projects and more Claude models. gemini-google-ai-pro-cz (Preis wird erfasst) gives 4x the free limits, Deep Research and 5 TB of storage.
Perplexity Pro (€ 15,14 pro Monat) is a search engine with models from several makers (GPT-6.1 Sol, Gemini 3.8 Flash, Claude Sonnet 5.5). Grok SuperGrok (€ 26,73 pro Monat) adds image and video generation. Copilot Pro is not on Microsoft's Czech page today; Copilot comes with microsoft-365-personal-cz (Preis wird erfasst) together with Word, Excel and 1 TB of OneDrive.
Who needs Pro and Max
Claude Max 5x (€ 90 pro Monat) and Claude Max 20x (€ 178 pro Monat) give 5x and 20x the Pro usage per session; the session limit resets every 5 hours, plus a weekly cap. ChatGPT Pro (Standard usage) (€ 89,09 pro Monat) is the lowest of OpenAI's three Pro tiers, gemini-google-ai-ultra-5x-cz (Preis wird erfasst) is Google's counterpart.
It makes sense when you work with AI several hours a day, typically coding or long documents, and the Pro limit runs out regularly. Whoever never exhausts Pro pays extra for Max with no gain.
