Prompt Cost Estimator – Prompt Optimization & Token Efficiency Tool

Prompt Cost Estimator is a web-based tool that helps developers and product teams get more value out of every token they spend on AI platforms. Instead of writing long, inefficient prompts, users can design concise, structured instructions and still generate rich, high-quality code and content. The tool supports JSON → TOON format conversion, allowing teams to transform existing JSON-based prompt structures into a more compact and human-readable TOON format. This makes prompts easier to maintain, reuse, and share across projects. Beyond conversion, Prompt Cost Estimator also offers ready-to-use prompt templates, helping users start fast without designing everything from scratch. By combining prompt optimization with cost awareness, the tool encourages a “less prompt, more product” mindset: fewer tokens, clearer instructions, more development output.
