Estimates assume 5,000 conversations a month, 60% handled by AI and 10 agent seats, at each vendor's published list price (the cost calculator's model); treat them as a floor, not a quote. Compliance rows are what vendors publicly claim, and “Not verified” means we have not confirmed that fact yet, not that the tool lacks it.
Choose Chatbase or SiteGPT?
Choose Chatbase if
Best for: Small teams and side projects that want an AI agent trained on their site and docs live in an afternoon, with a 7-day trial, a $32 a month entry price on annual billing, 95+ languages, actions through Zendesk, Stripe and Slack, and no sales call anywhere in the process.
- you need Email and Voice coverage
Look elsewhere if you run a large or regulated support operation: Chatbase is bootstrapped and self-serve by design, with no stated data residency, and its message-credit pricing gets expensive at high volume compared with per-resolution vendors.
Choose SiteGPT if
Best for: Small businesses and SaaS teams that want an inexpensive chatbot trained on their own site, from $39 a month, including Zendesk teams adding an AI first responder.
- you prefer its particular feature set and integrations
Look elsewhere if you need an agent that takes actions in billing or account systems, or a full help desk, since SiteGPT is a content-trained chatbot first.
About Chatbase
Chatbase might be the most impressive solo act in this directory. Founder Yasser Elsaid built the first version in about six weeks during his final university semester in Canada, riding the earliest wave of "chat with your data" excitement, and then kept building. Bootstrapped in Toronto with zero outside funding, Chatbase has passed $9 million in annual recurring revenue and more than 10,000 businesses, with testimonials from names like Bridgestone, IHG, and Miele, all without a sales team in sight.
The product is the self-serve ideal: point it at your website, docs, and files, tune the agent's behavior and appearance, and embed it with a script tag. What began as a question-answering widget has grown real support muscle, with actions through integrations like Zendesk, Slack, Stripe, and Calendly, smart escalation to humans, WhatsApp and Slack as channels, and 80+ languages. It remains the fastest path in this directory from "we should have an AI agent" to one live on your site.
Pricing runs on message credits: $32 a month for Hobby, $120 for Standard, and $400 for Pro on annual billing, 20 percent more month to month, each with a 7-day trial. The old free plan is gone, and removing the Chatbase branding is a paid add-on.
Chatbase is the right starting point for small teams and side projects, and honest about what it is not: there is no ticketing depth or enterprise deployment team. Start with the trial, see whether an AI agent moves your numbers, and graduate to a heavier platform only if you actually outgrow it.

About SiteGPT
SiteGPT trains a support chatbot on your own content and embeds it on any site you like. You give it a URL, a sitemap or YouTube videos, upload files, paste raw text, or connect Notion, Google Drive, Dropbox, OneDrive, Box or GitHub, and the bot answers visitors from that material. Quick prompts start conversations, a button hands a visitor to a live agent when the AI should not continue, lead forms capture contact details, and a weekly email digest reports last week's numbers, the top topics and the questions the bot could not answer. Beyond the website widget it runs in Slack, Google Chat, Messenger, Crisp, Freshdesk Messaging, Zoho SalesIQ and WhatsApp (an add-on).
Two things set it apart from the many tools like it. The first is the Zendesk AI Agent on the Scale plan: SiteGPT installs as the first responder inside Zendesk Messaging and hands conversations to human agents with full history, which lets a Zendesk team add AI without moving help desks. The second is how agent-friendly it has become: there is a CLI, a remote MCP server, a REST API and SDKs, and an AI coding agent can create and train a working bot from a single URL with no account, then hand back a claim link. The iOS app gives a team a live inbox with push alerts when a visitor asks for a human.
SiteGPT does not publish founder or company history on its site, so none is recorded here. It claims a SOC 2 Type II examination with no exceptions, GDPR certification and a HIPAA assessment by DPLMC International, with a BAA available on Enterprise, and support for more than 95 languages. Infrastructure runs on Cloudflare Workers. The one named reference on the site is CBS Bahamas, which escalates to Zendesk.
Pricing is published and message-based. Starter is $39 a month billed yearly ($59 monthly) for one chatbot and up to 4,000 GPT-4.1-mini messages; Growth is $79 yearly ($129 monthly) with API access, analytics and integrations; Scale is $259 yearly ($429 monthly) and adds webhooks, AI conversation insights and the Zendesk AI agent; Enterprise is custom. Every self-serve plan starts with a 7-day trial that needs a credit card. Choose SiteGPT if you are a small business or SaaS team that wants a straightforward, inexpensive bot trained on your site, especially one that can sit inside Zendesk. Skip it if you need agentic actions in billing or account systems, which this product does not emphasize, or if you want no credit card at signup.
