Buyer guide

How to choose an AI chatbot platform

Seven things worth comparing before you shortlist, and ten vendors described on each of them. We do not rank them and we do not score them: we sell one of these products, and a number we produced about a competitor would be worth exactly what you would expect. What is here can be checked against published pricing, hosting and certification terms. Pairs with the buyer guide, how we measure answer quality and the comparison matrix.

What to compare

Each of these is answerable from a vendor's own published terms. Ask for the answer in writing before the demo, not after.

CriterionNote
Vertical / industry fit Per-industry seed content, compliance posture, tone-of-voice presets out-of-the-box. Generic platforms leave this to the customer.
Data residency Where customer data is hosted and whether jurisdiction-specific hosting is offered. SCC 2021/914 transfer governance. Schrems II compliance.
Multilingual depth First-class non-English support beyond auto-translate. Hebrew RTL and Russian, with additional languages available on request.
Compliance posture HIPAA BAA-eligibility, GDPR DPA, SOC 2 status, ISO 27001 readiness.
Pricing model Flat-tier unlimited (favoured) > per-conversation > per-resolution (penalised).
Channel coverage Web widget + Telegram + WhatsApp Business + Instagram DM + email. Bundled vs add-on pricing.
Self-serve onboarding <30 min to first widget live without implementation-consultant engagement.
