Code explainer, doc translator, commit generator — AI tools that fit your workflow.
Legacy code, complex algorithms, obscure patterns. You need to understand it before you can fix it.
You found the perfect library but the documentation isn't in English. Google Translate mangles technical terms.
git commit -m "fix stuff" isn't cutting it. You want good commit messages but writing them takes mental energy.
Documentation is always the last priority. Rewriting it clearly takes time you don't have.
Confusing Code:
const debounce = (fn, delay) => { let timeoutId; return (...args) => { clearTimeout(timeoutId); timeoutId = setTimeout(() => fn.apply(this, args), delay); }; };
After "Explain":
This creates a debounced version of any function. When the returned function is called, it waits for the specified delay before executing. If called again during the delay, it resets the timer. This prevents a function from firing too frequently - useful for search inputs, window resizing, etc.
Your Diff:
+ const validateEmail = (email) => /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(email);
+ if (!validateEmail(input)) throw new Error('Invalid email');
Generated Commit:
feat(validation): add email validation with regex
- Add validateEmail helper function
- Throw error for invalid email format
