Best Prompts by AI Assistant

Each major AI assistant has different strengths, default behaviors, and contexts where it performs best. These collections are organized by assistant — not just by task — so you can match your prompt to the tool you are actually using.

Whether you are choosing between assistants for a specific task, or trying to get better results from the tool you already use daily, these pages explain what makes each assistant different and provide prompts built around its actual strengths.

How to choose the right assistant for a task

Different AI assistants genuinely handle different tasks better — not because of marketing positioning, but because of real differences in how they are trained, what they are connected to, and how they process instructions.

  • ChatGPT — strong for conversational tasks, structured creative work, and instruction-following with custom system prompts. Wide integration ecosystem via plugins and API.
  • Claude — handles long documents and complex analysis well. Tends to produce longer, more careful responses and is useful for tasks requiring nuanced judgment or detailed writing.
  • Gemini — connected to Google Search for grounded responses. Best for tasks where current, real-world information matters or where Google Workspace integration is useful.
  • Copilot — designed for productivity inside Microsoft 365. Best for document editing, email drafting, meeting summarization, and Excel tasks within the Microsoft ecosystem.
  • Perplexity — built around real-time web search with citations. Best for research tasks where you need current information with verifiable sources, not just AI-generated text.
