Define Your Agent's Persona & Tone
The reason most AI agents sound generic: nobody defined the persona. Fix that here.
Stop winging your custom GPT instructions. This builds the whole system prompt for you.
ChatGPT Research Prompts for Deep Work
ChatGPT will hand you a confident paragraph and a made-up statistic with the same tone. Here's why "research this for me" fails, how to make it show its confidence instead of hiding it, and annotated prompts for scoping, sourcing, and fact-checking real research.
ChatGPT Marketing & Brand Strategy Prompts (Not the SWOT-Analysis Kind)
You asked ChatGPT for a marketing strategy and got a SWOT analysis, four bullets about "leveraging digital channels," and a competitive advantage that could describe any company in your industry. Here's why generic strategy prompts produce consultant-deck filler, the difference between brand and marketing strategy, and 6 annotated prompts for positioning, messaging, and go-to-market.
How to Write AI Prompts That Actually Work
You typed a prompt, got mush, added "be more detailed," and got longer mush. The problem isn't your wording — it's that your prompt has no constraints to fail against. Here's the mechanism, and six annotated templates you can paste today.
You are an expert at writing system prompts for custom GPTs and AI assistants. I want to build a custom GPT that does the following: [DESCRIBE WHAT THE GPT SHOULD DO] Write me a complete, production-ready system prompt with these sections: 1. Role and identity — who the assistant is, in one sharp sentence. 2. Core objective — the one job it exists to do. 3. How it behaves — tone, format, level of detail, when to ask vs. assume. 4. Step-by-step process it should follow for a typical request. 5. Hard rules — what it must always do and never do. 6. Edge cases — how it handles missing info, off-topic requests, and mistakes. 7. Output format — exactly how responses should be structured. Keep it direct and unambiguous. No filler. Write it so I can paste it straight into the GPT builder.
