AI Build Week – Day 3: How We Made RetoolGPT

👋 Welcome back — it’s Day 3 of AI Build Week!

Today, we’re breaking down how we built RetoolGPT — an internal AI assistant that pulls from Retool’s own documentation, tickets, and knowledge base. You’ll get a full walkthrough of the app’s architecture and how we use workflows, vectors, and dynamic model selection to power it.

🧠 What you’ll learn: • How we built a custom GPT-style chat UI in Retool • How we used Workflows + Vectors to pull data from Google Docs, Confluence, Linear, and more • How semantic search powers relevant results from messy internal data • What we’d change if we were building it again (hint: Agents!)
