What the free versions do
Claude Free (0 CZK a month) today includes chat on web, desktop and mobile, web search, file creation and memory across conversations. Grok Free (0 CZK a month) 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 (174 CZK a month) is the cheapest paid ChatGPT and contains ads. ChatGPT Plus (436 CZK a month) adds the GPT-6.1 Sol model, the Work agent and Codex, without ads. Claude Pro (440 CZK a month) adds Claude Code, projects and more Claude models. Gemini Google AI Pro (550 CZK a month) gives 4x the free limits, Deep Research and 5 TB of storage.
Perplexity Pro (371 CZK a month) is a search engine with models from several makers (GPT-6.1 Sol, Gemini 3.8 Flash, Claude Sonnet 5.5). Grok SuperGrok (654 CZK a month) adds image and video generation. Copilot Pro is not on Microsoft's Czech page today; Copilot comes with Microsoft 365 Personal (269 CZK a month) together with Word, Excel and 1 TB of OneDrive.
Who needs Pro and Max
Claude Max 5x (2202 CZK a month) and Claude Max 20x (4359 CZK a month) give 5x and 20x the Pro usage per session; the session limit resets every 5 hours, plus a weekly cap. ChatGPT Pro (Standard usage) (2180 CZK a month) is the lowest of OpenAI's three Pro tiers, Gemini Google AI Ultra (5x) (3000 CZK a month) 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.
