AI Chat Hub — All AI Models, One Place
One free chat interface for Claude, GPT, Gemini, Grok and 300+ other AI models. For students, developers, writers, marketers, researchers — anyone. Plus a built-in YouTube creator layer if that's your thing.
Open AI Chat Hub — FreeFree to use • No credit card required
Switching between 5 different AI tabs to compare answers is exhausting. Fulhar's AI Chat Hub puts every leading model — Claude (Sonnet, Opus, Haiku), GPT (3.5, 4, 4 Turbo), Gemini (Flash, Pro), Grok, Llama, Mistral and 300+ more — behind a single chat window. Pick the right model for each task, switch mid-conversation, never lose context.
It's general-purpose: write code, summarise documents, plan trips, debug essays, learn languages, translate, brainstorm — anything you'd use ChatGPT for, do it here with model choice and unified chat history. And if you happen to be a YouTube creator, you also get optional channel-aware context that auto-injects your niche, subs and audience data into every reply.

Frequently asked questions
Is the AI chat hub really free?
Yes. Free accounts get unlimited chat with the standard model lineup. Premium model usage (e.g. Claude Opus, GPT-4 Turbo at full quota) is on a paid tier.
Which AI models can I use?
Claude (Sonnet, Opus, Haiku), GPT (3.5, 4, 4 Turbo), Gemini (Flash, Pro), Grok, Llama 3, Mistral and 300+ others through OpenRouter integration. Switch any time mid-conversation.
Do I have to be a YouTube creator to use this?
Not at all. The AI Chat Hub is general-purpose — students, developers, writers, marketers, researchers, anyone. The YouTube creator perks are an optional layer; if you don't link a channel, they simply don't activate.
Can I attach files and images?
Yes — drop in PDFs, screenshots, code files, spreadsheets. The AI reads them and you can chat about the contents.
Can I generate images here too?
Yes. Type a prompt, get an image — directly in the chat, no separate Midjourney/DALL-E tab needed.
Can I export chats?
Yes. One-click export to Markdown, PDF, or DOCX. Useful for reports, articles, scripts.
Is my chat data private?
Yes. Conversations are stored against your account only. We never train on your data and you can permanently delete any session at any time.
How is this different from ChatGPT?
ChatGPT gives you OpenAI models only. Fulhar gives you Claude, GPT, Gemini, Grok and 300+ others in one chat. Plus image generation, file attachments, export and (optional) YouTube creator perks — all on a free tier.
