🧠 AI Dev Helper — Hybrid Chrome Extension Built with ❤️ by HalxDocs Because debugging at 2 AM shouldn’t feel like spiritual warfare. 🚀 A fully hybrid AI coding assistant that lives in your browser.

AI Dev Helper gives you online AI, offline LLM, inline code tools, PR reviews, autocomplete, voice mode, error fixing, and a full AI sidebar—all inside ANY webpage.

Seamless. Fast. Context-aware. A true AI companion for real developers.

📌 Why This Exists

Because HalxDocs got tired of:

Googling “what is this error???” like a ritual

Copy-pasting code into ChatGPT like a caveman

JavaScript gaslighting him with undefined is not a function

PR reviewers saying “LGTM” after reviewing nothing

Fighting CSS at 3:14 PM

Using 5 AI tools for 1 problem

So he built ONE AI tool…

❤️ Built With Love by HalxDocs

If someone asks why this extension is so cracked, tell them:

“It runs on pure HalxDocs energy — and that cannot be downloaded, cloned, or pip installed.”

😂 Funny Reason This Was Built

Because:

StackOverflow answers are 10 years old

GitHub PR reviewers are half asleep

VSCode Copilot ignores you sometimes

And ChatGPT keeps forgetting context after 5 messages

HalxDocs said:

“Let me build my own AI that lives inside the browser knows what I’m seeing and fixes my code before I cry.”
