About

IT Error Decoder is a small, fast tool for IT admins, developers, and helpdesk staff. Paste any error message and get a plain-English explanation, the most likely cause, and a step-by-step fix you can actually run.

What we cover

• Microsoft Graph PowerShell errors
• Microsoft Teams (client and Teams Rooms)
• Vercel deployment errors
• Windows administration errors
• Microsoft Entra ID (Azure AD) permission errors

How matching works

We don't use any paid AI APIs. Matching is done client-side against a curated, open list of known error patterns. If your pasted text contains a known error fragment, we show the matching guide. Otherwise, we show a generic troubleshooting checklist.
