I tried 4 "AI Coding Assistant" Chrome extensions. Only one didn't make me close the tab in 5 minutes

I'm a backend dev who's been slowly moving toward frontend work. Last month I spent a weekend trying every AI coding Chrome extension I could find. Here's what actually worked and what was hype.

What I tested

1. Continue.dev in the browser. Promising in theory. In practice it kept forgetting the project context every time I switched tabs.




2. Phind. Search-first which is great for "how do I do X" but useless for "I'm in the middle of building Y and need help right now."




3. Codeium in-browser. Felt like a slightly smarter autocomplete. Not bad but not different from Copilot.




4. An AI side panel extension. This is the one I actually kept using. It doesn't try to autocomplete my code. It just sits in the sidebar and lets me paste snippets, ask questions, and copy answers back. No context pollution because it doesn't touch my editor.

What surprised me

The pattern I see in the AI coding tool space: most tools compete on features. The one that won me over is the simplest. It does one thing. Let me ask AI questions without leaving my browser tab. And does it well.

I think this is the same insight that made Notion win over Microsoft Word. Word could do everything. Notion did less but felt faster.

The real test

I wrote the same JavaScript function four times, once with each tool. The side panel gave me the cleanest answer because I could give it full context in one message and it didn't try to be clever. The other three kept suggesting frameworks I wasn't using.

What I'd recommend

If you're a frontend dev already deep in VS Code: stick with Copilot or Cursor. They own your editor and that integration matters.

If you're a backend dev, junior dev, or anyone who switches between 5 different contexts a day: try a side panel. Lower friction. Less context loss.

The listicle "5 best AI coding extensions 2026" articles usually rank tools by features. I rank by "did I keep using it after the first day." Only the side panel passed that test.
