The AI Prompt Builder for ChatGPT, Claude & Any LLM.
Describe your goal — the AI asks the right follow-up questions and assembles a structured, 7-component prompt for ChatGPT, Claude, Gemini, or any language model. Better outputs from the very first message.
No prompt engineering experience needed. Free to start.
Your prompts are leaving 80% of the AI's capability on the table
Most people dump a one-liner into ChatGPT and wonder why the output is generic. The truth is: language models are only as good as the instructions you give them. A structured prompt with clear context, constraints, and format dramatically changes the quality of every response.
Typical prompting
- "Write me a blog post about X" — no context, no constraints
- Generic outputs that need 3–4 rounds of revision
- Different format every time — no consistency
- No role definition — the AI guesses what expertise to use
- Copy-pasting half-baked templates from Reddit threads
With CookedBanana
- AI asks targeted follow-up questions — no missing context
- Precise outputs on the first message, minimal revision
- Consistent 7-component structure across all prompts
- Expert role defined — the AI knows its persona
- Reusable prompts saved to projects for your team
Three steps to a perfect LLM prompt
The LLM Prompt Builder uses a conversational approach to gather exactly what it needs before generating. No more guessing what parameters matter — the AI asks the right questions, in the right order, to build a prompt that works on the first try.
Step
01
Describe your goal
Tell the AI what task you need a prompt for. Be as vague or specific as you want — it will ask for what it needs to build the perfect instruction.
Step
02
Refine through conversation
The AI asks targeted follow-up questions to understand context, constraints, output expectations, and edge cases. You answer, it learns.
Step
03
Copy and deploy
Your structured 7-component prompt is ready. Copy it, paste it into ChatGPT, Claude, or any LLM. Get precise, consistent outputs from the first message.
7 components that make any LLM dramatically better
Every prompt generated by CookedBanana follows this proven structure. Each component eliminates a specific source of ambiguity that causes bad outputs.
Role
Who should the AI act as? Define the expert persona, domain knowledge, and professional context.
Context
Background information the AI needs — project details, audience, existing data, constraints.
Objective
The exact task to accomplish. Clear, measurable, actionable — no ambiguity.
Constraints
Rules, limitations, and boundaries. What to include, what to avoid, what format to follow.
Output Format
How the response should be structured — markdown, JSON, bullet points, table, code block.
Examples
Good and bad examples that calibrate the AI's understanding of what you want.
Tone
The voice and style — professional, casual, technical, persuasive, educational.
Everything you need for precise LLM prompting
Four capabilities that transform how you interact with language models — from conversational refinement to file-based context injection.
Conversational Refinement
Describe your goal in plain language. The AI asks targeted follow-up questions to fully understand your needs before generating anything — so the first prompt is the right one.
File Context
Attach images, PDFs or plain-text files as context. The AI reads them and uses the information to build a more accurate and relevant prompt — no manual copy-pasting.
7-Component Structure
Every prompt is organized into Role, Context, Objective, Constraints, Output Format, Examples, and Tone — the building blocks of a powerful, reusable LLM instruction.
Works with Any LLM
The generated prompt is optimized for ChatGPT, Claude, Gemini, Llama, Mistral, and any other language model you use. One prompt structure, universal compatibility.
One tool, unlimited applications
The LLM Prompt Builder works for any task you can delegate to a language model. Here are the most common use cases.
Copywriting & Content
Blog posts, product descriptions, email sequences, social media copy — with precise tone and structure.
Coding & Development
Code generation, debugging, documentation, architecture decisions — with constraints and output format.
Analysis & Research
Market analysis, data interpretation, competitor research — with structured methodology and examples.
Marketing & Strategy
Campaign briefs, audience segmentation, ad copy, A/B test variations — with brand voice and guidelines.

Frequently asked questions
Everything you need to know about the LLM Prompt Builder.
It's a conversational AI tool that helps you create structured, 7-component prompts for any language model. Instead of writing vague instructions, you describe your goal and the AI asks follow-up questions to build a precise, reusable prompt with Role, Context, Objective, Constraints, Output Format, Examples, and Tone.
The generated prompts are universally compatible. They work with ChatGPT (GPT-4o, o1, o3), Claude (Opus, Sonnet, Haiku), Gemini, Llama, Mistral, DeepSeek, and any other model that accepts natural language instructions.
A structured prompt explicitly defines what the AI should know (Context), what it should do (Objective), how it should do it (Constraints, Format), and how it should sound (Tone). This eliminates ambiguity and dramatically improves output quality, consistency, and reusability.
Yes. You can attach images, PDFs, and plain-text files during the conversation. The AI reads the content and uses it to build a more accurate prompt — no manual copy-pasting required.
ChatGPT doesn't ask you the right follow-up questions. CookedBanana's builder follows a systematic refinement process — it asks about your audience, constraints, edge cases, output format, and tone before generating anything. The result is a prompt that works on the first try.
You can sign up and try the tool for free with a limited number of generations. No credit card required. The Image Prompt Generator is also included in every plan.
