The chatbots you remember from 2019 were intent classifiers: buyer types “hours,” bot answers with hours. That’s not what we’re talking about. A modern AI sales agent runs on a frontier reasoning model (Claude, GPT) grounded in your content — your products, your pricing, your applications, your distributor list. It can configure, cross-sell, answer spec questions, hand off, escalate, and capture leads without sounding like a script.
The reason this is newly possible: the models got smart enough to handle nuance two years ago, and grounding (RAG, tool use) got reliable enough to keep them honest. The combination is what unlocks “sounds like a senior sales engineer at 2am.”
