Frequently asked questions
What is the best AI support tool?
It depends on what you need. Clanker Support is the best fit if you want a single script tag, model-agnostic AI, human escalation, and the option to self-host. Intercom, Chatwoot, and Chatbase reach further if you need WhatsApp, voice, or a full multi-channel platform today.
Which AI support tools are self-hostable?
Of the tools compared here, Clanker Support and Chatwoot are self-hostable. Clanker Support is a focused widget that runs serverless on the edge; Chatwoot is a full multi-channel platform on Rails and PostgreSQL. Chatbase, Fin, Intercom, and Crisp are hosted-only.
How is Clanker Support different from Intercom?
Intercom is a full customer-communication platform spanning support, sales, and marketing. Clanker Support is purpose-built for AI support — one script tag, your choice of model, human escalation, and email threading — so it costs less and there's far less to learn if support is all you need.
Can I use my own AI model with these tools?
Clanker Support is model-agnostic: it runs on LLM Gateway, so you pick the model per project and swap it with a config change. Fin runs on proprietary models, and most other tools lock you to their own AI. Self-hosting Clanker Support means you bring your own keys.
