Features
Review code with AI, without losing developer trust
LearnCodeGuide combines bug detection, security checks, refactor suggestions, code explanations, and unit test ideas in one workflow. Built for developers who want fast answers and exact fixes.
Bug detection
Catch logic mistakes, edge cases, and likely runtime failures before they hit production.
Security scanning
Detect risky patterns like SQL injection, XSS, unsafe auth flows, and weak input handling.
Refactor suggestions
Get cleaner, shorter, and easier-to-maintain code suggestions with practical fixes.
Step-by-step explanations
Understand what the code does, why it fails, and what each fix changes.
Unit test ideas
Generate useful test cases around edge cases, invalid input, and common failure paths.
Multi-model verification
Use a second AI pass for higher confidence when the analysis matters more.
Use cases
Built for real developer workflows, not just generic scanning
Whether you are debugging pasted snippets, reviewing legacy code, or checking risky logic before shipping, LearnCodeGuide helps you understand and improve code quickly.
Debug code faster
Paste a snippet, see the likely failure points, and get exact replacement suggestions instead of vague warnings.
•Find exact lines and likely causes of runtime failures.
•Get fixes that are easier to apply than raw linter output.
Understand inherited or legacy code
Learn what unfamiliar code does with plain-English explanations and structured issue breakdowns.
•Useful for juniors, freelancers, and small SaaS teams without formal code review.
•Great for snippets copied from older projects or repos you did not write.
Catch security issues early
Scan common risky patterns before they turn into incidents or production fire drills.
Improve code quality before shipping
Use refactor suggestions and generated test ideas to increase confidence before merge or deploy.
Useful across five languages
Start with JavaScript, Python, Java, C#, and C++, then expand based on user demand.
How it works
From pasted code to clear fixes, in a few seconds
The workflow is simple: submit code, run the analysis mode you need, and review issues, explanations, and suggested fixes in one place.
1
Paste code or upload a file
Choose a language, pick a mode like Debug, Security, Refactor, Explain, Tests, or All-in-One.
2
Run the analysis
LearnCodeGuide evaluates the snippet and optionally uses a second AI model for extra verification.
3
Review exact findings and fixes
See issue severity, affected lines, why it matters, and what to replace to improve the code.
