Trains a chat agent on your website, PDFs, and docs, then embeds it to answer questions, qualify leads, and book demos.
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.
Starter is $29/month for one agent and 1,000 messages; Free covers 50 messages/month with no card required.
Use tool ↗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.
Watch out: Message limits reset monthly, and going over them likely requires an upgrade mid-cycle.
