I’ve been learning frontend development, and one thing that consistently slowed me down was trying to understand JavaScript error messages. Some are clear, but many feel cryptic when you’re still early in your journey. I wanted something that didn’t just tell me what the error was, but why it happened and what I should look at next.

So I built a small browser‑based tool that takes a JS error and explains it in simpler language. It also suggests possible causes and things to check. Everything runs locally in the browser — no backend, no data stored.

What it does:

Parses the error message

Explains it in plain English

Suggests likely causes

Offers possible next steps

Simple, minimal UI

Works entirely client‑side

I'd appreciate feedback on literally anything on the tool.

There’s a feedback section on the site as well. I’m actively improving it and would love to hear what the HN community thinks.
