A generative AI assistant is a chat app built on a large language model: you ask in plain language, and it answers questions, writes and summarizes text, and works with files you upload.

From each vendor's pricing page, docs or help pages, checked 3 October 2026, in USD. ChatGPT prices are from OpenAI's docs at learn.chatgpt.com. Perplexity's and xAI's own pricing pages blocked our checks, so their paid prices are the US App Store in-app prices, which can differ from web prices. Gemini prices are for the US. Promotions are left out.
