AI Code Editor Extension for Developers
Inline AI coding assistance everywhere you write code in the browser — refactor, explain, test, complete. 300+ models behind one shortcut. Free for indie devs and small teams.
Add to Chrome — FreeFree to use • No credit card required
Editor extensions like Copilot are great if you live inside VS Code, but a lot of coding happens outside it — GitHub PRs, code review tools, JSFiddle, CodeSandbox, web IDEs, even GitHub Issues. Fulhar's AI Code Editor Extension brings inline AI to all of them. Highlight a snippet → press the shortcut → get an explanation, a refactor, a test or a completion right in the page.
It uses the same 300+ model engine as Fulhar's AI Chat Hub, so you can switch between Claude (great for big-picture refactors), GPT (great for unit tests) and Gemini (free vision for screenshot debugging) without leaving the editor.
Why creators use this ai code editor extension for developers
Inline AI in any web editor
Works in GitHub PR review, GitHub Issues, JSFiddle, CodeSandbox, StackBlitz, web IDEs, and most textareas — not just VS Code.
300+ AI models
Claude (Sonnet/Opus/Haiku), GPT, Gemini, Grok, Llama, Mistral and more. Pick the right tool for each task.
Refactor, explain, test, complete
Highlight code → pick action → AI rewrites in place. Four core actions cover 90% of dev usage.
Streaming output
Token-by-token so you can interrupt the moment AI drifts — no waiting 30s for a full reply.
Context-aware
Pulls surrounding code automatically so explanations reference real variables and imports — not generic.
Multi-language
Python, JavaScript, TypeScript, Go, Rust, Java, C++, Ruby, PHP — and most others.
Privacy-respecting
No telemetry. Code never leaves the model provider's pipe. We don't train on user code.
Free for individuals
No card. Standard models unlimited. Premium models (Opus, GPT-4) on a paid tier.
How it works
- 1
Install the extension from the Chrome Web Store (one click).
- 2
Highlight any code on a webpage (PR, JSFiddle, GitHub issue, codepen — anywhere).
- 3
Press the shortcut (Cmd+Shift+L by default) and pick: Refactor / Explain / Test / Complete.
- 4
AI rewrites or annotates in place. Accept, reject, or pivot.
What you get
- Stop tab-switching to ChatGPT every time you need code help.
- Works where Copilot doesn't — PR review, web IDEs, issue trackers.
- Compare model outputs in one shortcut — Claude's refactor vs GPT's tests.
- Free, lightweight, no proprietary lock-in.
Frequently asked questions
Is the AI code editor extension free?
Yes. Install and use unlimited inline AI on the standard model lineup. Premium models (Claude Opus, GPT-4 Turbo at full quota) are on a paid tier.
How is this different from GitHub Copilot?
Copilot is excellent inside VS Code. Fulhar runs in your *browser* — works in PR review, GitHub Issues, web IDEs (CodeSandbox, JSFiddle, StackBlitz), and any textarea. Different surface area, complementary tool.
Which browsers and editors does it work in?
Any Chromium browser (Chrome, Edge, Brave, Arc). Inside the browser it activates on most code-aware UIs: GitHub, GitLab, Bitbucket, JSFiddle, CodeSandbox, StackBlitz, Replit, CodePen, plus any textarea.
Will my code be sent to the AI provider?
Yes — that's how AI inference works. Code is sent to the selected model provider (OpenAI, Anthropic, Google, etc.) for the duration of the request. No code is stored by Fulhar. Use a self-hosted model option if your code is sensitive.
Is there a VS Code version?
Not yet. The roadmap has it scheduled for next quarter. For now, use the browser extension or Fulhar's web AI Chat Hub for VS Code-side workflows.
Can I configure the keyboard shortcut?
Yes — shortcut is fully customisable from Chrome's extension shortcut settings.
Does it work offline?
No — AI inference requires a network connection to the model provider. The extension itself loads instantly from local cache.
Is my code private?
We don't log or store your code. Each request goes directly to the chosen model provider. No telemetry, no tracking.
Ready to add to chrome?
Free to start. No credit card. Sign in only when you're ready to save your work.
