I have an interview action idea, my invention is about a device that is act as therapist with AI, but the therapist will be someone who you lost. And the device can creat this person depending on users given feature.
Tech companies generally, including Google, don't pay for unsolicited ideas.
The best way to get paid for an idea by Google is to either apply for a job and get hired by them; or to found your own company based on the idea and grow it to the point that Google is interested in purchasing it.
