The CustomGPT alternative that also resolves tickets
CustomGPT users look elsewhere when the bot needs to do more than answer: check an order, book a slot, escalate an angry customer to a person.
SupportAi keeps the grounded answers and adds the support workflow around them.

Four things you get that CustomGPT does not offer

Every channel
Web, Slack, WhatsApp and email on every plan.
UK/EU hosting
GBP billing and a DPA on request.

Why teams leave CustomGPT
The most common reasons we hear from teams switching from CustomGPT:
- Limited live-data actions and no deterministic webhook layer
- Channel coverage centred on web and API
- US hosting and USD billing
Who should stay on CustomGPT
Organisations that need an accurate internal or public knowledge assistant over large document sets.
If that describes you, SupportAi may not be a better fit and we would rather say so than win a migration you regret.
What stays the same
Your knowledge sources, your embed location and your team. SupportAi crawls the same URLs, ingests the same documents and takes the same script-tag slot in your site. Conversation history for new visitors starts fresh; transcripts can be imported on request.
Frequently asked questions
Test in the Playground with your hardest questions first. Guardrails and fallback messages keep the agent on-topic.
