Scripted vs LLM-based AI chatbots — pick the right category first
Before comparing vendors, decide which category you're shopping in. Scripted (decision-tree) chatbots ask you to draw every possible conversation flow by hand. They were the only option a decade ago and they're cheap, but they break the moment a real customer phrases a question off-script — which is most of the time.
LLM-based AI chatbots read your real content (website, PDFs, help center) and generate answers in natural language. For a small business, this is almost always the right choice in 2026: you maintain web pages, not flowcharts, and the bot handles the long tail of questions you never anticipated. Every recommendation below assumes you're in the LLM category.
The SMB evaluation checklist
Six things to verify before you commit. If a vendor misses two or more, keep looking.
LLM-based, not scripted
The bot should read your website and answer in natural language — no decision trees to maintain by hand.
Live in under an hour
Paste URL → crawl → embed snippet. If onboarding takes a week, it's overbuilt for SMB.
Flat, predictable pricing
Avoid per-agent and per-message-overage traps. Look for one plan price with a generous conversation allowance.
Multi-channel from day one
Website widget today; WhatsApp / Messenger / Telegram you can flip on later without migrating.
GDPR + data residency
Signed DPA, EU or US data residency, and your content NOT used to train shared models.
Multilingual replies
Auto-detects the visitor's language — essential for tourist-facing, bilingual, or border-region SMBs.
Pricing traps to avoid
- • Per-agent pricing. Punishes you for growing the team. SMBs should pay for the bot, not the seats.
- • Per-message overage. A viral support thread or a scraper attack can land a four-figure bill. Pick a plan with predictable, capped pricing.
- • "Contact sales" pricing. If the vendor won't publish numbers, they're priced for enterprise — you're not the target.
- • Hidden onboarding fees. Modern AI chatbots install themselves from a URL; an "implementation package" is a 2018 product wearing a 2026 jacket.
Data security checklist for SMBs
Most small businesses underestimate this until a customer asks "where is my data stored?". Before signing up, confirm: (1) the vendor signs a Data Processing Addendum, (2) you can choose EU or US data residency, (3) your conversations and uploaded content are NOT used to train any shared model, and (4) you can export and delete your data on demand. ReplAiChat ships all four on every plan, including the free tier.
Multi-channel: do you need it on day one?
Probably not. Most SMBs start with the website widget and add WhatsApp 1–3 months later, once they've seen what visitors actually ask. The important part is that your vendor supports WhatsApp, Messenger, and Telegram natively — so you flip a switch instead of migrating to a new platform when the time comes.
