Free Browser Extensions from Fulhar
Three lightweight, privacy-first Chrome extensions: AI chat in a side panel, AI coding assistance in any web editor, and a YouTube SEO + tag generator. Free to install, no card required.
Browser extensions are the fastest path to making AI a part of your daily workflow. Instead of switching to a separate ChatGPT tab to ask a question, opening a code AI in VS Code, or paying for a YouTube SEO tool, Fulhar's extensions sit quietly in your toolbar and activate the moment you need them.
Each extension is built on the same engine as the Fulhar web app — 300+ AI models, streaming responses, file attachments, image generation. They share login (optional) with your web account so chat history follows you between desktop and extension.

Frequently asked questions
Are the extensions really free?
Yes. All Fulhar Chrome extensions are free to install and use. Standard model usage is unlimited. Premium model quotas (Claude Opus, GPT-4 Turbo) are on a paid tier shared with the web app.
Which browsers do they work on?
Any Chromium-based browser: Chrome, Edge, Brave, Arc, Opera, Vivaldi. Firefox versions are on the roadmap.
Do I need a Fulhar account?
Not required. Each extension works fully without login. Signing in adds web/extension chat history sync and access to premium models.
Are the extensions privacy-respecting?
Yes. Zero telemetry, zero analytics tracking. Conversations are stored locally (without login) or against your Fulhar account (with login). We never train on user data.
How heavy are they on my browser?
All three extensions are sub-1MB and use ~5MB memory in idle. They won't slow your browser even with dozens of open tabs.
Can I use them together?
Yes — they run independently. Many users keep all three pinned: AI Chat Hub for general use, Code Editor for dev work, YouTube SEO Tag for creator workflow.
