Prompt Builder
100% PrivateAI & Prompt ToolsAssemble a well-structured AI prompt from guided fields for role, task, context, tone and output format.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
Template assembly only: the prompt below is built from the fields you fill in, in a fixed section order. No AI model writes, rewrites or improves anything here.
Add at least one field, ideally the task, and the assembled prompt will appear here.
- 1Fill in the task first: what you actually want the AI to do.
- 2Add a role and context if they matter, for example who the reader is.
- 3Set the tone and output format, then list constraints one per line.
- 4Copy the assembled prompt and paste it into your AI chat tool.
Role: "You are a patient maths tutor"; Task: "Explain fractions to a complete beginner"; Context: "The reader is 11 years old and learns best with food examples"; Tone: "Friendly and encouraging"; Output format: "Short paragraphs with one worked example"; Constraints: "Avoid jargon" and "Use examples from cooking". The builder produces: ## Role You are a patient maths tutor ## Task Explain fractions to a complete beginner ## Context The reader is 11 years old and learns best with food examples ## Tone Friendly and encouraging ## Output format Short paragraphs with one worked example ## Constraints - Avoid jargon - Use examples from cooking
- Sections always appear in the same order (Role, Task, Context, Tone, Output format, Constraints) and empty sections are skipped entirely.
- The builder does not improve or reword your text; it only arranges it. Wording quality is still up to you.
- Constraints are split by line: one constraint per line becomes one bullet.
No. It is a template: your own words are placed into headed sections. Nothing is sent to a model and nothing is generated.
About this tool
The Prompt Builder assembles a well-structured AI prompt from guided fields: role, task, context, tone, output format and constraints. Instead of a blank box, you fill in the parts a good prompt needs, and the tool arranges them in a fixed order with clear headings, skipping any section you leave empty. It is template assembly, not AI writing: every word in the result is yours.
