AI Chatbot Buying Hub: Find the Right Comparison

A buyer looking for an "AI chatbot" is usually choosing among three different purchases. A website knowledge agent answers from your docs on your site. A team inbox with AI adds an assistant to the live chat and tickets your people already staff. An existing-helpdesk overlay puts AI inside the helpdesk you already pay for. They solve different problems and bill on different meters, so the fastest way to find the right comparison is to identify your channel first. This page routes you to the guide that matches your situation; detailed plan inventories, prices, and reviews live in the linked articles.

TL;DR

You are buying one of three things: a website knowledge agent, a team inbox with AI, or an AI overlay on a helpdesk you already run.
The billing meter reveals the real cost: message or AI credits, human conversations, or outcomes and resolutions.
Use the routing table, open the guide for your channel, and don't compare vendors that perform different jobs.

Three purchases, three meters

1. Website knowledge agent

A website knowledge agent trains on your help center, documentation, and site content, then answers questions in a widget. It fits when you have solid content, want 24/7 coverage, and don't staff a chat channel. The meter is message credits on Chatbase or model-weighted AI credits on YourGPT, and the two are not interchangeable. YourGPT's 10 million credits is a pool spent at a model-dependent rate; a heavy reasoning model burns it far faster. Chatbase credits are counted per message, and auto-recharge can push a $32 Hobby plan far higher in a launch week. Renew at the tier that survived 14 days of real usage.

2. Team inbox with AI

A team inbox product keeps live chat and ticketing in one place where AI and humans share the same thread. It fits when you already answer customers in a shared inbox and want AI to take the repetitive load while people keep ownership of complex cases. The meter is billable human conversations: Tidio counts a conversation only when a human replies or initiates it. Lyro is sold as a separate AI product, and a Lyro reply does not make a conversation billable. Buying both creates two meters, so know the split before you commit.

3. Existing-helpdesk AI overlay

An overlay runs AI inside Zendesk, Intercom, or Gorgias, using the same ticket and customer context and handing off to your team. It fits when you already pay for seats, have workflows and SLAs, and want AI to resolve within the desk. The meter is outcomes or resolved interactions. Intercom Fin charges $0.99 per outcome and counts a confirmed resolution, a configured procedure handoff, a disqualification, or a self-serve routing; sales qualification is $9.99. Zendesk bills automated resolutions as usage, so ask for the current included allowance and overage rate on a quote. Gorgias bills per resolved interaction, its public price requires a quote, and legacy accounts created before May 28, 2025 follow different terms.

If you already run a helpdesk, don't put a second standalone chatbot in front of it. Two surfaces can promise the same refund, and you'll pay two meters for one customer thread.

Which guide do you need?

If you're asking…	Start here	Meter to watch
"I just want a bot on my website answering from my docs and help center."	AI chatbots for websites · Chatbase vs. YourGPT	Message credits or AI credits
"I already answer live chat and email, and I want AI beside my team."	Chatbot vs. live chat · Tidio vs. YourGPT	Human conversations + separate AI conversations
"We already pay for Zendesk, Intercom, or Gorgias."	Help desk comparison	Outcomes or resolved interactions
"Shopify store: orders, returns, shipping, refunds."	AI agents for ecommerce · Ecommerce AI support	Depends on vendor: per-resolution (Gorgias) or AI credits (YourGPT)
"I need to understand the billing units before comparing."	AI chatbot pricing guide	All three meters

For account-specific data like orders or refunds, require a customer login before the bot shares records; an email address alone is not proof of identity.

Worked routing example (hypothetical)

Scenario: a mid-size SaaS company with eight support staff, a help center, an email inbox, and no paid helpdesk yet. Roughly 60% of tickets are repetitive: password resets, billing FAQ, and doc lookups.

Deploy a website knowledge agent. Put a Chatbase Hobby or YourGPT Essential agent on the help center. Both start around $30-40 per month on annual billing. Cap Chatbase auto-recharge, set YourGPT credit alerts, and after 14 days read actual message or credit use. Renew at the tier that holds.
Decide about the human inbox. If the team keeps answering in the shared inbox, weigh Tidio's human-conversation meter against moving to a helpdesk with AI included. If you were about to buy a helpdesk anyway, skip the standalone widget and evaluate helpdesk AI directly; otherwise you pay two meters for the same customer thread.
Pick one surface for money promises. Because both the widget and the helpdesk touch refunds, choose one as the source of truth so a customer never gets two different answers about the same refund. Route order-status and refund requests through an authenticated customer session rather than trusting a typed email or order number.

Conclusion

Match the purchase to the channel you already run, then read the meter. A website-only team usually fits a knowledge agent, which adds 24/7 coverage without staffing a chat channel; a staffed inbox needs a human-conversation product; a team that already pays for a helpdesk should add AI inside it instead of a parallel bot. Open the matching guide from the routing table, confirm the current price at checkout, and set billable-unit limits before you go live.
