Perplexity combines web search with conversational answers and source links. Pro Search and Research provide additional ways to investigate a question, with access that varies by plan.
Grok is xAI’s chatbot, distinguished by live access to the X platform for up-to-the-minute news and public sentiment. It offers image generation and a deliberately less filtered conversational style, with deeper reasoning modes on paid plans.
Le Chat is the assistant from French AI lab Mistral, known for very fast responses and a strong privacy stance under European data rules. It includes web search, image generation and code interpretation, with generous limits on the free tier.
Poe, built by Quora, is an aggregator that puts GPT, Claude, Gemini, Grok and dozens of other models behind a single subscription and interface. You can switch models mid-chat, build custom bots and compare answers side by side — handy for people who don’t want one vendor lock-in.
