Overview

Thinkstack is a no-code AI agent and chatbot generator for support, sales, and other customer-facing workflows. It lets teams build a chatbot, train it on their own knowledge sources, customize the experience, and embed it on a website or other channels.

The product combines LLM-powered conversation with actions, forms, conditional flows, integrations, and human handoff. The published help content shows a setup path that starts with naming the bot, adding knowledge sources, configuring settings, previewing the result, and then copying an embed script into a site.

Core capabilities

Train on your own data

Train chatbots on URLs, uploaded files, CSVs, Q&A inputs, or Notion workspace content so responses come from your own material.

Website and channel embedding

Copy the embed script into a website to add the bot as a chat bubble or chat window, and deploy it across sites and other channels.

Automation and actions

Configure action-based workflows, conditional flows, API triggers, forms, and external integrations so the bot can do more than answer questions.

Human handoff routing

Pass conversations to human agents when needed, with routing to teams such as sales or support based on the query context.

Brand and conversation customization

Customize the chatbot’s name, subheading, placeholder text, welcome message, appearance, and brand styling to fit the site it appears on.

Integrations and data sync

Connect the bot to tools such as Zapier, CRMs, Google Drive, and external APIs to retrieve or update data during conversations.
