What they are
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.
ChatGPT
ChatGPT is a large language model chatbot from OpenAI that generates text, answers questions, drafts content, and reasons through complex problems in a back-and-forth conversation. Online creators use it for scripting videos, writing captions, brainstorming ideas, and repurposing content across formats. The free tier runs GPT-5.5 instant and is genuinely useful for most writing tasks, while the Plus plan unlocks GPT-4o with faster responses and image understanding. Output quality varies by prompt skill, so results often need editing before publishing.
