My friend showed me an AI clone his company built from one employee’s 14 months of Slack messages

My buddy manages a remote team and showed me something last week that honestly freaked me out.

His company ran a pilot – trained a model on 14 months of one employee’s Slack messages, emails, and meeting notes. The AI version replies to clients in her voice. References people by name. Even uses “haha” the way she does.

She has no idea it exists.

The economics: $47/month to run. She costs considerably more than that. The pilot showed it handling 3x her message volume with the same client satisfaction scores.

I started thinking about which jobs are most exposed and it maps almost perfectly to how much of your work happens through text. Customer support, marketing, PM roles – basically anything where 80%+ of your output is digital communication. Engineering seems lower (maybe 70%?) because architecture decisions and code review still need judgment that’s hard to capture from Slack history alone.

The part that stuck with me: the stuff the model couldn’t do well was all relationship context. Like knowing which client panics before renewals, or that your PM needs bad news delivered on a walk not in a meeting room. None of that lives in any system.

Has anyone else’s company started rolling out “AI assistants” that seem weirdly good at mimicking specific people?

edit: to be clear, I don’t think this means everyone gets fired tomorrow. But the economics are wild and I think most people working remote haven’t thought about the fact that literally everything they type is training data
