Plain Language Code Explainer helps you turn dense or unfamiliar code into a readable walkthrough. It is ideal when you inherit a file, review a teammate's function, or study code in a new language. The prompt pushes the model to explain what each part does, how data moves through the logic, and which lines control the final outcome. Instead of dumping a generic summary, it produces a step-by-step explanation that is easy to follow.
This template is built for junior developers, product-minded engineers, and technical writers who need a clear understanding of code behavior. It emphasizes line-by-line explanation, purpose, inputs, outputs, and side effects. The model can also point out hidden assumptions, confusing naming, and places where a comment would help. That makes it useful for onboarding, code walkthroughs, and cross-functional collaboration where not everyone reads code fluently.
To customize, paste the code into {{CODE}}, specify the language in {{LANGUAGE}}, and define the audience in {{AUDIENCE}}. If you want the explanation to be more technical or more beginner-friendly, set {{DEPTH}} accordingly. The expected output is a plain-English overview followed by a structured breakdown of functions, variables, and control flow. Use this code explanation prompt whenever you need clarity before making edits, writing tests, or documenting behavior.
Key features
- Plain-English explanations for unfamiliar codebases and functions
- Breaks logic into readable sections with minimal jargon
- Highlights inputs, outputs, and control flow clearly
- Useful for onboarding, documentation, and code walkthroughs

- → Technical writers documenting application behavior
- → Product engineers reviewing unfamiliar implementation details
Tips
- 💡 Ask for examples of inputs and outputs to make behavior concrete
- 💡 Set DEPTH to 'beginner' when the code uses unfamiliar APIs
- 💡 Include related helper functions if the file depends on hidden context
What you'll get
A structured explanation with a high-level overview, a walkthrough of control flow, important variables, edge cases, and a short plain-language summary. It reads like a senior engineer teaching the code to a newcomer.
