AI support you can actually trust in front of customers
Zero AI hallucinations. Every reply cites its sources inline. With custom escalation guardrails, you dictate exactly when the AI hands off to your inbox. You retain absolute control.
Start with a 7-day trial. Paid plans start at $29/month.
Inline source citations
The AI only answers using the knowledge base you provide, citing exactly which document and URL it referenced. No guessing, no fabricated answers.
Immediate handoffs for sensitive cases
Billing disputes, security questionnaires, and refund exceptions bypass the AI entirely. They are routed straight to your inbox for founder review.
Granular workspace access
Starter workspaces are restricted to you. Growing teams use custom roles and private invitations to ensure members access only what they need.
Continuous gap detection
Track exactly where the AI struggled or initiated a handoff. Fix knowledge holes in one click before they turn into customer complaints.
Clear technical safeguards, zero compliance theater
SupportFast earns your trust through transparent product mechanisms, precise inline source citations, structured handoff logs, granular role authorization, and robust sandbox testing. We don't advertise badges we haven't earned or security certifications we cannot back up.
Automate safely, control absolutely
Start by connecting a single source, test the widget in our sandbox workspace, and expand AI coverage only when you are completely confident.
