Not necessarily. Many people keep one paid assistant and use another’s free plan. Compare ChatGPT vs Claude, ChatGPT vs Gemini, ChatGPT vs DeepSeek or ChatGPT vs Grok.
Perplexity for research, Claude or Gemini for everyday help, and DeepSeek if you want strong reasoning for free and your data policy allows it.
No consumer assistant is truly unlimited on its free plan; all cap usage of their best models.
