The old Decody page at /chatbots was “6 best custom AI chatbots for
business websites.” People still type that URL. Some of them wanted Intercom.
Some of them wanted a girlfriend. We will not bait-and-switch either group.
If you meant a chatbot for a company website
- Intercom Fin — support deflection with the most mature agent story.
- Zendesk AI — if Zendesk already is the ticket pile.
- HubSpot Breeze customer agent — if the CRM is HubSpot. See also the marketing tools ranking.
- Ada — automated support for high-volume ecommerce.
- Drift (Salesloft) — conversational capture for B2B sites that still believe in chat widgets.
Custom GPT-on-your-docs wrappers are fine for an internal wiki. They are sloppy on a public marketing site without retrieval, logging, and a human escape hatch.
If you meant an uncensored companion
That is a different product. We test those with paid accounts and a memory protocol named Marlowe. Start here:
- Best NSFW AI chatbots (2026) — writing quality, not widgets.
- Best AI girlfriend apps — the overall ranking.
- Memory-test results — who remembered the dog.
Business chatbots should never train on your customers’ private tickets without a contract. Companion chatbots should never see your real name. Same instinct, two desks.
