What happens when the AI doesn't know the answer?

It triggers a human handoff. The conversation is instantly routed to your shared team inbox, along with a draft reply and the user's full context. Your team can review, edit, and send the final response.

Can humans take over a conversation at any time?

Yes. From your dashboard, you can click 'Pause AI' on any active conversation and instantly reply as a human. The AI will stay quiet until you choose to re-enable it.

How do I train the AI?

You don't need to 'train' it. Just paste your help center URL, upload PDFs, or paste plain text. SupportFast automatically ingests the content. When you update your website, the AI re-syncs automatically.

Does it work for small teams or solo founders?

Absolutely. SupportFast was built specifically for lean teams. It handles the repetitive questions so founders can focus on building, while keeping a calm, organized inbox for the complex issues that actually need human judgment.

What is included in the free trial?

The 7-day trial includes the plan you choose, with the same AI reply, source, user, workspace, and team caps shown on the pricing page.

Yes. We use strong encryption for data at rest and in transit. Your documentation and customer conversations are stored securely. We do not use your private data to train public AI models.
