Custom AI chat agent trained on your own website data
Build a chatbot trained on your business data and guided by your own instructions so answers reflect your products and policies.
Add the assistant to any website with a single script tag and start chatting within minutes.
Monitor all messages from a backend dashboard and intervene in conversations whenever circumstances require a human.
An interface to leading large language models, with higher tiers unlocking the best-performing assistant available.

Custom GPT-powered support chatbots trained on your own content
Point SupportAI at your website, files, product pages or videos and it builds a knowledge base your chatbot answers from, with no code required beyond a single embed snippet.
Use the same chatbot on your website, WhatsApp, Messenger and other channels so customers get consistent answers wherever they reach out.
Beyond support, preconfigured use cases cover lead capture and email list growth, sales conversations, bookings and appointments, product recommendations, feedback collection and internal employee Q&A.
Edit, add and update the content your bot answers from, review real conversation transcripts, and monitor where answers fall short so you can close those gaps over time.
