Which one should you actually pick?

ReplAiChat

Best for SMBs, agencies, and websites that need leads and bookings — not just FAQs.

Most generous free tier, native Calendly/Cal.com booking, plugins for every major CMS, no per-seat fees.

Intercom Fin

Best for mid-market support teams already on Intercom.

Deeply integrated with the Intercom helpdesk. Pricey on a per-resolution model — overkill for marketing sites.

Chatbase

Best for a pure FAQ-style bot without sales workflows.

Simple, document-trained, fast to set up. Lacks native booking, multi-CMS plugins, and a true handoff inbox.

Tidio Lyro

Best if you already use Tidio live chat.

Lyro plugs into Tidio's existing widget. Sensible if you've already paid for Tidio; less compelling on its own.

How we'd pick the best AI chatbot for a website in 2026

"Best" only means anything in context. A solo founder shipping a SaaS landing page, a 12-person ecommerce team running Shopify, and a 200-seat support org on Intercom need very different AI chatbots — and the wrong choice usually costs more than the tool itself. Here's how we'd reason about it.

Start from your job-to-be-done, not the feature list

If the job is "answer FAQs and capture leads from my marketing site", you want a no-code AI chatbot that crawls your website, drops in via one snippet, and has lead capture and calendar booking native — that's the sweet spot ReplAiChat is built for. If the job is "deflect tickets inside an established support organisation", Intercom Fin's per-resolution pricing actually makes sense.

Watch out for pricing-model traps

Seat-based plans punish you for adding teammates. Per-resolution plans punish you for being good at marketing. Per-message plans (ReplAiChat, Chatbase) are the easiest to forecast for a website chatbot — your cost scales with actual usage, not with the size of your team or the success of your funnel.

Free tiers are not equal

Intercom Fin doesn't have a real free tier — only a trial. Chatbase's free tier is tight on messages. Tidio's free tier is decent but Lyro itself is paid. ReplAiChat's free tier is meant for production use on small sites, including the crawler, dashboard, and embeddable widget.

Test before you commit

Whichever vendor is on your shortlist, point each at the same five pages from your site and ask the same five real customer questions. The right AI chatbot for your website is almost always the one whose answers you wouldn't be embarrassed to send yourself.

FAQs

What's the best AI chatbot for a website in 2026?

It depends on company size. For SMBs and solo founders, ReplAiChat and Chatbase are the most affordable and quickest to launch. For mid-market support teams with an existing Intercom helpdesk, Intercom Fin is the natural extension. Tidio Lyro is a strong middle ground if you already use Tidio for live chat.

Is Intercom Fin worth the cost?

Intercom Fin charges per resolved conversation (around $0.99) on top of seat-based Intercom pricing. For high-volume support teams already on Intercom it can pay for itself. For a marketing site that needs sales-qualified leads and FAQ answers, it's usually overkill compared to ReplAiChat, Chatbase, or Tidio.

How does ReplAiChat compare to Chatbase?

Both train an AI chatbot on your website with one snippet. ReplAiChat adds native calendar booking, a human-handoff inbox, multi-channel plugins (WordPress, Shopify, Wix, Squarespace), and a more generous free tier. Chatbase is solid for a pure FAQ-style bot without lead workflows.

Can I migrate from Tidio to ReplAiChat?

Yes — export your FAQs from Tidio, paste them into ReplAiChat's curated Q&A panel, point the crawler at your site, and swap one script tag. Most migrations take under an hour.
