Prompt Engineering Toolkit
A collection of 50 standalone browser-based tools for analyzing, refining, scoring and building prompts for large language models, each a single HTML file with no build step.
Prompt Engineering Toolkit is a collection of 50 standalone web tools for crafting, analyzing and refining prompts for large language models. Each tool is a single HTML file with inline CSS and JavaScript, runs entirely in the browser with no dependencies or build step, and works offline.
The tools are grouped by purpose: prompt analysis and scoring, persona builders for roles such as expert, teacher or recruiter, prompt refiners that expand, simplify or reformat a prompt, a sandbox and version tracker for testing and comparing prompts, purpose-built builders for content such as blog posts or resumes, and generators for zero-shot, few-shot and chain-of-thought prompting.
