Use tool ↗About sensai
sensai builds a conversational agent from a business's own content: website pages, PDFs, and other documents feed the training step, and the resulting agent goes on a website to answer visitor questions, qualify leads, capture contact details, and book demo calls. Plans differ mainly by how many agents can run, how many messages they handle per month, and which underlying model powers replies, with the top tier adding GPT-4.1, Claude Opus 4, and Gemini 2.5 Pro. The operator, sensai Inc, does not publish its headquarters country. There is no public developer API mentioned anywhere on the site.

Pros & cons of 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
Best for
- Small businesses wanting a trained support agent on their site
- Teams that need lead capture and demo booking built into chat
- Anyone who wants a 7-day trial before committing to a paid tier
Not for
- Teams needing a developer API or headless integration
- Businesses with complex, multi-department support needs
Watch out: Message limits reset monthly, and going over them likely requires an upgrade mid-cycle.
