What they are

Grok

Grok is a large language model chatbot built by xAI that answers questions, drafts content, analyzes data, and generates images. It pulls live information from X (formerly Twitter) and the broader web, making it more current than many competitors. Creators use it for research, writing assistance, and brainstorming. The free tier is limited in usage, and the personality-forward tone can occasionally prioritize wit over precision.

Perplexity

Perplexity is a research-focused AI assistant that combines a language model with real-time web retrieval, citing sources in its answers. The Pro plan routes queries across multiple frontier models rather than one provider. It is built for fact-checking and research, though it is weaker at coding and creative generation than general assistants.
