Key Buyer Criteria: What to Look For

Before committing to a platform, evaluate each tool against these four essential dimensions:

1. Strict Grounded Accuracy

The chatbot must never invent policies, pricing, or product specs. It must provide clickable citations back to your website.

2. Sub-Second Latency & Real-Time Streaming

Visitors will abandon slow chatbots. Look for instant Server-Sent Events (SSE) streaming.

3. Outbound Actions & Lead Capture

The ability to trigger webhooks, query order status, book calendar meetings, and capture visitor contact details.

4. Predictable Cost & Scalability

Avoid per-seat or per-resolution fee traps that punish you for growing your support volume.
