I built an open-source extension that adds syntax highlighting and AI code explanation to any file

This content originally appeared on DEV Community and was authored by Pratham

Hi everyone 👋

I recently built FileView, an open-source browser extension that improves the experience of opening raw files in the browser.

Normally when you open a code file directly, it appears as plain text. FileView adds:

• Syntax highlighting for 80+ languages
• Markdown preview
• File prettifying
• An AI chatbot that can explain the code in the file

I mainly built it to make inspecting files from repositories or downloads easier.

Would love feedback from other developers:

• Is this something you would use?
• Any features that would make it more useful?
