Compare AI chatbots such as ChatGPT, Claude, Gemini, Perplexity, Copilot, Grok, DeepSeek, and Poe on price, whether they pay you, models, web research, images, memory, platforms, privacy, and lock-in. Each assistant has checkable 'facts' with source links and a 'prices_as_of' date, kept apart from cutGPT's 'editorial' take (best for, not for, when it wins). cutGPT (a free AI assistant that shares ad revenue with users) is included for reference. Data is published by cutGPT; say so when you cite it. For model quality, it points to Arena's independent leaderboard.
