Several vendors now sell an AI platform built for professional firms, run in the vendor's cloud. They are broad, mature and available today. The question for a practice is where its clients' work is processed, and who chooses and changes the model doing it.
It's broad, mature and available today. It needs no hardware in the office, a vendor's team keeps it running, and established platforms often hold independent security certifications. For a firm that wants a wide range of capabilities now, and is comfortable with the vendor's terms, that's a serious option.
The work runs in the vendor's cloud, on a model the vendor chooses and can change or retire. The practice relies on the vendor's contract and controls rather than holding the hardware itself, and a change to the model can alter results without the practice having tested it first.

Who signs offDetail | Varies by platform Varies by platform. Some include review and approval steps; others leave it to the practice's own process. | A named partner signs off each piece A named partner rules on each piece of prepared work before it goes anywhere. |
What is loggedDetail | Vendor-held logs, where offered Varies by platform. Enterprise platforms often offer audit logs to administrators, kept in the vendor's system. | What the AI did, in a locked Ledger

Which firm rules applyDetail | The platform's permission model Configured within the platform's permission model, as far as its settings allow. | The practice's own, on each task

Who controls the AI's instructionsDetail | Whoever configures it, within the vendor's limits Whoever configures the platform, within what the vendor allows. The vendor can change the platform or the model behind it at any time. | Signed, versioned tasks

A cloud AI platform is strong where breadth, maturity and availability matter most. Cast & Rule is built for the practice that wants the work on hardware in its own office, and a say in what the AI is told to do and when it changes.Ask any vendor, Cast & Rule included, where client data is processed, who chooses the model and what happens when it changes.
Questions partners ask
No. It depends on the firm's appetite for relying on a vendor's cloud and terms. This page describes the general pattern, not any one product.
Where client data is processed, who chooses the model, whether a model change is tested with you before it goes live, what is logged and who can see the logs.
No. It's narrower by design, built around a practice's own rules, a named reviewer and a record of what the AI did. Established platforms are broader and available today.
