What do you mean for the assistant to be yours? There is a core model somewhere that needs to be trained and the cost/technical requirements are prohibitive for that to be done by each individual. If the model is local, is that enough? The data of course should be yours - and until we solve information leaks in AI (never?), it will have to be or the product has huge viability risks.
