An agent for your site that answers like a human
An AI agent answers first: it understands the question, replies like a person, and calls an operator in the moment it cannot cope. One line of code — unlimited agents, free forever.
Everything support needs — in one widget
An AI agent answers
The agent answers first and writes like a person, not a scripted FAQ. Built on what we learned shipping GPTunneL.
Human handoff
When the AI can't solve it, the chat is handed to a live agent seamlessly — the customer never hits a dead end.
Acts for the user
The assistant can even open the right page for the visitor and guide them through your product, not just talk.
Unlimited agents
Add your whole team at no cost. No per-seat pricing, ever.
Fits your site
Light and dark themes, automatic matching to the visitor’s own, plus your colours and corner style.
Any model you like
ChatGPT, Claude, Gemini or DeepSeek — switch in one click, with the cost per conversation shown up front.
Realtime chat
Messages, read receipts and typing indicators instantly over WebSocket.
Analytics & ratings
Volume, response rate, who's most active, and a rating for every resolved chat.
An agent answers first, not an operator
We built GPTunneL, so we know how to make AI assistants that actually help. ChatDeck puts that assistant front and center.
Replies like a human
Answers in your tone, following your instruction — not canned templates.
Knows when to step back
If it can't resolve the request, it hands off to a human instantly, with full context.
Takes action
Opens pages, walks users through flows, and answers in context — a real assistant, not a chatbot.
Flexible setup
Tone, instructions and per-page rules — without a line of code.

Teams love it
The AI closes most questions on its own — we only jump in for the tricky ones now.
Adding the whole team for free was the deciding factor. No per-seat math.
The assistant opening the right page for users is genuinely magic.
One line of code and it didn't break our layout. Set it and forget it.
Frequently asked
Is it really free?+
Yes. Unlimited agents and the AI assistant are included on the free plan. We may add paid tiers later for advanced needs.
How is the AI different?+
The agent answers from your instruction, writes like a person, and hands the chat to an operator the moment it cannot help. Individual pages can carry their own rules — your pricing page can be answered differently.
Can the assistant really open pages?+
Yes — it can navigate the visitor to the right page and guide them through your product, not just send links.
What does the AI cost?+
The service itself is free. The agent needs a GPTunneL key, so you pay only for tokens at the provider’s rates. Settings show what one conversation costs — from a fraction of a rouble on light models to a few roubles on the strongest ones.
Will the widget break my site?+
No. It runs in a Shadow DOM, so widget and site styles are fully isolated.
