Tip: The more specific your task description and context, the better the generated prompt will perform.
Gemini Tips
- • Gemini favors directness — be precise and concise, avoid fluff
- • Use Markdown headings (# Identity, # Constraints) to structure complex prompts
- • Place role and constraints at the TOP of the prompt to anchor reasoning
- • For complex tasks, include explicit planning/decomposition steps

Frequently Asked Questions
What is a Gemini prompt generator?
A Gemini prompt generator helps you create optimized prompts specifically designed for Google's Gemini AI models. It structures your inputs following Gemini-specific best practices — including structured formatting with Markdown/XML tags, constraint-first placement, and explicit output format specification — to get the best possible results.
How is prompting Gemini different from ChatGPT?
Gemini favors directness over verbosity and produces less verbose output by default. It responds best to structured prompts using Markdown headings or XML tags, with constraints placed at the very top. Unlike ChatGPT, you may need to explicitly request detailed or conversational responses. Gemini also has strong multimodal capabilities and can process images, audio, and video as first-class inputs.
Which Gemini model should I use?
Gemini 2.5 Pro is best for complex reasoning, coding, and analysis tasks. Gemini 2.5 Flash is optimized for speed and cost-efficiency while still being highly capable. Gemini 3 is the latest generation with improved instruction following, structured output, and constraint adherence. Our generator adapts the prompt style based on your selected model.
Is this tool free to use?
Yes! You get 3 free prompt generations per day with no signup required. For unlimited access, sign up for a Promptslove membership which includes all AI tools and 20,000+ premium prompts.
Can I use these prompts with other AI models?
While optimized for Gemini, the structured prompting approach works well across models. The Markdown/XML formatting and constraint-first pattern are effective with Claude, ChatGPT, and other LLMs. Some Gemini-specific features like multimodal coherence instructions may not apply to all models.
What is structured prompting?
Structured prompting uses Markdown headings or XML-style tags to organize different sections of your prompt (identity, constraints, context, output format). This provides unambiguous boundaries that help Gemini distinguish between instructions and data, leading to more accurate and consistent results.
Should I use self-critique directives?
Yes, for quality-sensitive tasks! Adding "Before returning your final response, review your output against the original constraints" encourages Gemini to self-check its work. This is especially effective for Gemini 3, which has strong self-evaluation capabilities.
How many prompts can I generate for free?
You get 3 free prompt generations every 24 hours. This resets automatically. For unlimited generations, consider signing up for a Promptslove membership.
