"We can't put client files in ChatGPT"
We install ModelSide Chat and document tools on a workstation in your office. The files never leave hardware you own, and nothing is sent to ModelSide or any cloud.

We build the workstation, install the models, connect them to your documents, and keep it all running in your office. Nothing leaves the building.
