The AI Code Explainer Prep tool helps developers safely prepare code snippets before asking an AI to explain them. It automatically detects the programming language, masks sensitive information like API keys and database connection strings, adds context markers, and generates a well-structured prompt you can paste directly into ChatGPT, Claude, or any other AI assistant.
Step-by-Step
Paste your code — Drop in any code snippet you want explained, from a single function to an entire module.
Review language detection — The tool automatically identifies the programming language (JavaScript, Python, TypeScript, Go, Rust, Java, C#, and many more).
Check the sensitivity scan — Highlighted sections show detected API keys, database connection strings, environment variable values, passwords, tokens, and other sensitive data that will be masked.
Add optional context — Provide a brief description of what the code is part of (e.g., "This is a middleware function in an Express.js API") to help the AI give a more relevant explanation.
Copy the generated prompt — The tool produces a ready-to-paste prompt like "Explain this [language] code step by step: ..." with your cleaned code embedded.
Features
Language Auto-Detection — Identifies 30+ programming languages by syntax patterns, keywords, and file conventions so the generated prompt includes accurate language context.
Sensitive Data Masking — Scans for and replaces API keys, Bearer tokens, database connection URIs, AWS credentials, private keys, .env variable values, and hardcoded passwords with safe placeholder markers like [REDACTED_API_KEY].
Context Markers — Inserts structural comments that help the AI understand code boundaries, function purposes, and module relationships without needing the full codebase.
Explanation Prompt Generation — Creates prompts optimized for code explanation, including instructions like "Explain line by line," "Identify potential bugs," "Describe the algorithm used," and "Suggest improvements."
Multiple Explanation Levels — Choose between beginner-friendly, intermediate, or expert-level explanation prompts depending on your audience.
Common Use Cases
Code Reviews — Prepare unfamiliar code for AI-assisted review without leaking credentials or secrets.
Learning — Understand open-source code or legacy codebases by generating clear AI explanations.
Documentation — Generate explanation prompts that help AI write inline comments or README documentation.
Onboarding — Help new team members understand complex code by providing AI-ready, context-rich prompts.
Security Audits — Safely share code with AI assistants for analysis without exposing sensitive credentials.
Why Use This Tool
Pasting raw code into AI chatbots is risky — you might accidentally share API keys, database passwords, or proprietary logic. This tool ensures sensitive data is masked before the code leaves your machine. The auto-detected language and context markers also produce vastly better AI explanations compared to pasting unlabeled code. Whether you are learning, reviewing, or documenting, this prep tool makes every AI code explanation safer and more accurate.
