Universal Prompt Designer runs a guided interview, asks targeted questions about the project, and builds a complete, structured prompt from the answers. No template to fill in. No prior knowledge of prompt engineering required. Just describe the project in plain language and answer the questions as they come, in any language. The output follows an 8-part framework: role and persona, purpose and goal, inputs, instructions and logic steps, output requirements, constraints, fallback logic, and tone guidance. That structure gives the target AI model enough context to produce consistent results without follow-up corrections. Most sessions take 3 to 7 credits to complete. Bring more context upfront and the session gets shorter. The finished prompt is ready to paste directly into ChatGPT, Claude, Gemini, Cursor, v0, Perplexity, NotebookLM, Figma Make, or whatever tool the project calls for. A companion tool, Visual Prompt Architect, handles image and video generation prompts separately. Same interview format, different vocabulary, built around the way image models actually process input rather than forcing a language model framework onto visual work. Free tier includes 15 credits a month. Builder tier is unlimited. Sessions are private, login-protected, and not used for model training.
