About AI Bug Explainer
Staring at code that clearly does the wrong thing, with no obvious reason why, is a familiar kind of stuck. The AI Bug Explainer lets you paste in the problematic code and get a plain-language explanation of what's likely going wrong, which can shorten the time between confusion and a fix.
Drop in the snippet that's misbehaving, and the tool points out probable issues and explains them in clear terms. It's free, browser-based, and requires no signup, so you get a second opinion instantly. Use it as a hint rather than a verdict: it reasons about the code you paste without seeing the rest of your project, so confirm its diagnosis against your actual runtime behavior.

FAQ
Do I need to paste the whole file?
Usually just the relevant snippet is enough, but include any context like inputs or surrounding logic that affects the bug. More context means a better explanation.
Can it see my whole project?
No. It only analyzes the code you paste, so bugs caused by other files, dependencies, or runtime state may be missed. Verify its explanation against actual behavior.
Will it fix the bug for me?
Its focus is explaining the likely issue. It may suggest a direction, but you should apply and test the fix yourself to confirm it resolves the problem.
Can I use AI Bug Explainer on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
