AI Code Explainer
About this tool
Understand unfamiliar code — overview, line by line, or pitched at a beginner, with real risks flagged.
Reading code you did not write is most of the job, and the hardest part is not syntax. It is working out the intent behind a function that has been patched by four people over three years.
Paste a snippet and choose your depth: a one-paragraph overview to orient yourself, line by line for something genuinely dense, or a beginner explanation that defines the language features as it goes. Anything actually risky gets flagged — an unhandled error path, an injection point, an off-by-one — but it does not pad the output with style opinions your linter already covers. Where the snippet depends on context you have not pasted, it says what is missing rather than inventing a plausible-sounding explanation of code it cannot see.
How to use
- Paste the code, optionally name the language, and choose how deep an explanation you need
- Press Generate and give it a few seconds.
- Copy what you need, or generate again for a different take — every run is fresh.
