sensai

Sensai lets you build an AI chatbot that's trained specifically on your business. You point it at your website, upload PDFs, or write custom Q&A pairs, and it learns all about your products, pricing, and policies. Once it's ready, you embed it on your site with a single line of code. The chatbot handles customer questions, qualifies leads, and can even book demos or hand off to a human when needed.

Getting started takes minutes. After signing up, you connect your data sources — crawl a website URL, upload documents, or add your own text snippets. Then you customize the agent's look and tone, set up lead-capture rules, and paste the embed script. Sensai uses different AI models depending on your plan: the free tier runs on GPT-4o-mini, while the Pro plan gives you access to GPT-4.1, Claude Opus 4, and Gemini 2.5 Pro. The agent can also integrate with Cal.com and Calendly for scheduling meetings.

Sensai is best for small to medium businesses, SaaS companies, and e-commerce stores that want to offer 24/7 customer support without scaling a support team. It's also useful for turning website visitors into leads — the agent captures names and email addresses mid-conversation and pushes them straight to your inbox. If you run a business that gets the same questions over and over, Sensai can take that load off your plate.
