What Is An AI Code Explainer
An AI code explainer converts source code into plain English. It calls out inputs, important branches, side effects, and outputs. You get a step by step narrative you can skim fast. No setup. No plugins. Just paste and read.
How To Use The Tool In 15 Seconds
- Paste your code into the box.
- Click Explain.
- Read the summary and the numbered steps.
- If the result feels long, click Clear and try a smaller snippet.
That is it. Small pastes produce sharper explanations.
Why I Built It
I wanted a way to understand unfamiliar code without digging line by line. Students need quick mental models. Busy engineers need fast context during reviews. This tool removes the friction so you can focus on ideas instead of syntax.
What You Get In The Output
- A one paragraph summary of the goal.
- A numbered walkthrough of the flow.
- Notes on inputs and return values.
- Pointers to risky spots like hidden globals or silent failures.
- Small tips to simplify the code next time.
The tone is practical. Zero filler. No trivia.
What Languages Work Well
JavaScript, TypeScript, Python, Java, C Sharp, Go, PHP, and SQL explain cleanly. Pseudocode works fine too. If it looks like code, the explainer will try to map it into normal language.
How This Helps In Code Review
You paste the changed function, click Explain, and copy the summary into your review note. Reviewers now understand intent in seconds. Fewer questions. Faster merges. Better feedback on design instead of syntax.
Privacy And Safety
The page calls an API through a lightweight proxy. No signup. Do not paste secrets. If you paste something sensitive by mistake, rotate it. Keep your snippets focused on logic, not credentials.
Frequently Asked Questions (FAQs)
What Does An AI Code Explainer Do
It reads a pasted snippet and returns a short description of purpose, flow, inputs, outputs, and risks that deserve tests or guards.
Can I Use It For Any Language
Yes for common languages such as JavaScript, TypeScript, Python, Java, C Sharp, Go, PHP, and Ruby. Stick to focused snippets for best clarity.
Is My Code Safe To Paste
The tool runs in your browser with a simple proxy. Paste only code you would share in a review. Avoid secrets. If you paste a token by mistake, rotate it.
Will It Suggest Exact Fixes
It prefers small steps. It will suggest naming and guards. For big changes use the explainer first, then a refactoring tool or a dedicated reviewer.
How Long Can A Snippet Be
Keep it short. A function or a small class is perfect. If you paste a large file the output becomes broad and less actionable.
