What is an AI agent builder
An AI agent builder is a platform that helps you create agents that do real work. Agents read documents access APIs and run multi step workflows. They do more than reply. They act. Builders combine model orchestration tool connectors storage and monitoring. This removes most engineering overhead. You can focus on outcomes rather than plumbing.
Why builders beat simple chatbots
Chatbots mostly answer questions from a script. Agents plan a set of steps to reach a goal. Agents can call APIs update records and follow up until a task completes. This makes them better for support sales HR and ops work. Use agents when you need actions like scheduling refunds or creating tickets.

Check RAG and doc versioning so agents use current data. Finally look for active community and vendor support.
Ai Agent Cost and pricing tips
Most builders use credits or message based pricing. Expect higher cost for large models and frequent API calls. Ask if the vendor lets you use your own model key or if they bill model usage inside their plan. Run a trial workflow to estimate monthly cost before you commit.
