Setup: auto-crawl vs. manual sources
Chatbase builds its knowledge base from sources you add — uploaded files, pasted text, or specific links. That gives you control, but it also means setup work every time your content changes. ChatSys takes the opposite approach: paste one URL and it crawls every page on your domain automatically — product descriptions, pricing, FAQs, policies, and blog posts — then trains a large language model on that content. When your site changes, re-crawling keeps the agent current with no manual re-upload.
Pricing: flat and predictable
ChatSys pricing is flat, with no per-seat fees and no usage or credit metering. Pro is $19/month (5 chatbots, 1,000 messages, 5 MB knowledge base, human takeover) and Premium is $39/month (10 chatbots, 5,000 messages, 50 MB knowledge, removed branding, visitor voice notes, and live web answers). Both include a 7-day free trial with no credit card. Chatbase's entry paid plan starts around $19/month, but ChatSys bundles full-site auto-crawl, re-crawling to stay current, and one-click human takeover into a price you can predict — no seat math, no usage-credit surprises. Need SSO, an SLA, or a dedicated account manager? Enterprise is custom-priced — just contact us.
Live human takeover — the feature Chatbase is missing
ChatSys includes one-click human takeover on every plan: spot a hot lead or a complex issue in the live dashboard, click once, and you are chatting directly with the visitor while the AI steps aside. For sales-driven sites, that turns the chatbot from a deflection tool into a conversion tool. Chatbase has no built-in live handoff.
When Chatbase might still fit
Chatbase is a capable tool, and if your use case is a document-trained assistant built from a curated set of files — rather than a live, full-site agent — its source-by-source model may suit you. If you want the fastest path from website to a working, self-updating agent with live takeover, ChatSys is the leaner choice. See also the AI chatbot builder guide and our SiteGPT comparison.
