What our research says

Chatbase

The fastest route from a folder of help docs to a working support widget, and priced accordingly once real traffic arrives. Credits are the whole story: 700 messages a month at $32 is a small site's volume, and the jump to a plan that carries actual traffic is $120, then $400. Budget from expected conversations, not from the feature grid.

Pros

  • Crawl-and-embed setup produces a usable widget in an afternoon with no retrieval plumbing to write
  • Actions and human handoff mean it degrades into a ticket rather than a dead end
  • A real free tier exists for evaluation, and every paid plan carries a 7-day trial

Cons

  • API access is gated to Standard at $120/month, four times the entry price
  • Overage at $40 per 1,000 credits is steep next to the in-plan rate on Pro
  • Removing vendor branding costs $1,188/year, more than the entire Hobby plan
  • Free-tier agents are deleted after 14 days of inactivity, so an abandoned evaluation disappears

sensai

sensai is a straightforward way to put a trained support-and-sales agent on a small business site without writing prompts from scratch, and the message-based tiers make cost predictable. It competes in a crowded field of similar chat-widget builders, and there's no API for teams that want it embedded somewhere other than a website.

Pros

  • Trains directly on existing website pages, PDFs, and docs
  • Books demos and captures lead details inside the chat
  • Pro tier offers a choice of several current frontier models
  • Free plan needs no credit card to start

Cons

  • No public API for custom integrations
  • Storage per agent is small even on paid tiers (25 MB on Pro)
  • Company discloses no headquarters location
