Frequently asked questions
How do you compare AI models fairly?
Compare what you will actually get: the plan price, the usage limits, which models the plan unlocks, and the tools around the model such as web search, file upload, image generation or code execution. Benchmarks change monthly and rarely match everyday use, so this site compares documented features and limits, each linked to the vendor's official page.
What is the difference between an AI model and an AI assistant?
A model, such as a GPT, Claude or Gemini model, is the engine that generates text. An assistant is the app built around it: ChatGPT, Claude, Gemini and others add plans, limits, memory, web search, file handling and mobile apps. Two assistants can even use the same underlying model, like Perplexity and Poe, which offer several vendors' models.
Can I compare three AI assistants at once?
Yes. Use the comparison tool on this page: tick two or three assistants, for example Claude, ChatGPT and Gemini, and the table shows their plans, prices, models, context window and features side by side. The link updates as you choose, so you can share or bookmark a three-way comparison such as Claude vs ChatGPT vs Grok.
