Chatbase

Chatbase is a build-your-own AI agent platform rather than a helpdesk. You create an agent, train it on your website, help docs, files and pasted text, choose a model, and deploy it as a website chat widget and, on higher plans, across WhatsApp, Messenger, Instagram, Slack and voice, with a built-in helpdesk inbox arriving at the Basic tier. That makes it attractive to a technical-leaning solo founder who wants an agent on a marketing site or product today, without migrating email support anywhere. Its Actions and Procedures let the agent call external systems — checking data, booking through Calendly, looking up order or account information via connected tools and APIs — and integrations with Zendesk, Intercom, Freshdesk, Gorgias and others let unresolved conversations flow into a real inbox. Handoff and human takeover exist, but this is not an email-first support operation; teams that live in tickets will feel the seams. The pricing trap is credits. Every model request burns message credits, a single conversation with actions can burn several, and premium models burn more, so a cheap Hobby plan can evaporate faster than the conversation count suggests. You control that by choosing a leaner model and limiting actions, and auto-recharge stops the agent going dark — at a price. No-code friendly, but it rewards tinkerers.

Flat monthly plan for a bundle of message credits — each AI model request spends credits, so one conversation typically spends several credits
