Chatbots & Assistants IA

No single assistant wins every task. Claude and ChatGPT lead general-purpose conversation, reasoning and writing, while Perplexity focuses on search-grounded answers with citations. Claude Cowork targets collaborative, agentic workflows, and tools like ClickUp and Amplitude embed assistants inside project and product analytics. ai-hunter.org compares them by use case rather than naming one permanent winner.

Yes. ChatGPT, Claude and Perplexity all offer free tiers that cover everyday questions, drafting and quick research, usually with limits on usage or access to the newest models. Free plans suit light or occasional needs, while paid tiers add higher limits, stronger reasoning and integrations. Check whether the free access is permanent or a time-limited trial before committing.
