Thinkstack
Freemium · $16/moNo-code AI chatbot builder for support and sales on your website
What is Thinkstack?
Thinkstack lets businesses build AI chatbots trained on their own content and embed them on a website with a snippet of code. The bots answer support and sales questions around the clock and can pass a chat to a human agent.
Bots learn from URLs, files, CSVs, Q&A pairs and Notion workspaces. Beyond answering questions, they can run actions, collect details through conversational forms and suggest next steps to guide visitors.
Chatbots can be deployed on Shopify and other site builders, and connected to WhatsApp, Instagram, Facebook Messenger and Zapier. White-label options let agencies resell bots under their own brand, and the Ultra plan can run on your own OpenAI key.
