Key Buyer Criteria
What to evaluate before choosing a customer support chatbot in 2026.
Strict Grounded Accuracy
The chatbot must never invent policies, pricing, or product specs. It must provide clickable citations back to your website.
Sub-Second Latency & Real-Time Streaming
Visitors will abandon slow chatbots. Look for instant Server-Sent Events (SSE) streaming.
Outbound Actions & Lead Capture
The ability to trigger webhooks, query order status, book calendar meetings, and capture visitor contact details.
Predictable Cost & Scalability
Avoid per-seat or per-resolution fee traps that punish you for growing your support volume.
