Developers often inherit codebases with little to no documentation. Understanding unfamiliar code takes hours of reading and mental mapping. ExplainMyCode provides automatic code documentation through AI-powered analysis.
Legacy systems are critical to businesses but often lack maintainers who understand them. Modernization projects stall because nobody knows what the old code does. Our API code analysis generates documentation automatically.
Security vulnerabilities slip into production because manual code review cannot catch everything. Automated tools often produce noisy false positives. ExplainMyCode focuses on real, observable security issues.
New team members spend weeks ramping up on unfamiliar codebases. Documentation is outdated or missing, and senior developers are too busy to explain everything. AI code explanation accelerates onboarding.
Building code analysis tools from scratch requires ML expertise and months of development. Most teams cannot afford to build their own. ExplainMyCode provides a ready-to-use REST API for code analysis.
Simply paste your code into the text area, select the programming language, and click "Explain". Our AI analyzes the code structure, identifies functions, dependencies, and potential issues, then returns a comprehensive explanation in seconds.
ExplainMyCode currently supports JavaScript, TypeScript, Python, Java, Solidity, PHP, and Ruby. We are actively adding support for Go, Rust, C++, and C# based on user demand.
Yes. Our security analysis mode specifically looks for common vulnerabilities including SQL injection, XSS, authentication flaws, hardcoded secrets, insecure cryptography, and more. Each issue includes severity rating and description.
You can try ExplainMyCode for free with limited usage. For production use, we offer affordable plans starting at $9/month for 100 analyses. Visit RapidAPI to see all pricing tiers.
Get your API key from RapidAPI, then make a POST request to our /explain endpoint with your code and language. The API returns structured JSON with summary, purpose, dependencies, complexity, issues, and function breakdowns.
ExplainMyCode returns always-structured JSON with zero hallucination rules. Unlike general-purpose AI, our prompts are specifically engineered for code analysis with predictable formatting. You get consistent, parseable output every time, no markdown, no conversational text, just structured data ready for integration.
