A well-designed chatbot answers 40-60% of messages automatically, at quality — and gives your team back time for what matters. Here's the full landscape for building yours in 2026.
Types of WhatsApp chatbots
- Keyword (rules): responds when the customer types "X". Most common.

Frequently asked questions
Keyword chatbot or AI chatbot?
For SMBs in 2026, start with keywords. Covers 80% of cases with 20% of the effort. AI fits when volume justifies it.
Can I run a chatbot only outside business hours?
Yes. Set up the flow with an 'after-hours' trigger and it only fires in that window.
Does the chatbot work on mobile?
Zapext runs on WhatsApp Web (computer). Your customer chats from their phone as usual.
