Why pay for ChatGPT Plus, Claude Pro AND Gemini Advanced separately when you can get all of them — plus 300+ more models — in one free Chrome extension? Fulhar's AI extension opens a side panel on any tab. Pick a model, type your prompt, get a streaming response. Switch from Claude Opus to GPT-5 mid-conversation. Attach files. Generate images. All without leaving the page you're on.
Under 1MB, zero tracking, free forever. Most users keep it pinned to their toolbar as their daily AI sidekick — the fastest way to compare answers from multiple models without juggling tabs and subscriptions.

Frequently asked questions
Is the AI chat extension really free?
Yes. The free tier gives daily credits that refresh every 24 hours — enough for ~50-100 messages a day across all 300+ models including Claude Opus and GPT-5. Heavy users (1000+ messages/day) upgrade for higher limits, but the free tier is genuinely usable.
How is this different from official ChatGPT or Claude extensions?
Official extensions only give you ONE provider's models. Fulhar's extension gives you Claude, GPT, Gemini, Grok and 300+ others in the same side panel — and you can switch between them mid-conversation. Plus it's free.
Do I need separate API keys for each model?
No. Fulhar handles all the model providers behind the scenes. You just pick a model and chat. No API key management, no separate accounts.
Which AI models can I use?
All major frontier models including Claude (Opus, Sonnet, Haiku), GPT (4o, 4.1, 5, o1), Gemini (2.5 Pro, Flash), Grok 4, Llama 4, DeepSeek, Qwen, Mistral, and 300+ more.
Can it read the page I'm on?
Only when you explicitly select text and right-click → "Ask Fulhar". The extension never reads page content automatically — privacy by design.
Will my account be safe?
Yes. The extension can't access any of your other website accounts. It only sends what you type (and any text you explicitly select) to our API.
Which browsers work?
Any Chromium browser: Chrome, Edge, Brave, Arc, Opera, Vivaldi. Firefox support is on the roadmap.
Do you train AI on my conversations?
No. We do not use your chat data to train any AI model. Your conversations are encrypted in transit and at rest.
Is my data tracked?
No. Zero telemetry, zero analytics scripts inside the extension. The only network calls are to our chat API for AI responses.
