I'd hold off until AI can do that job for us at no charge.
Based on their privacy policy it looks like Trim takes a lot more than just a cut of the savings. They collect a shit ton of very personal data. They sell your personal data to advertisers, their "partners", and other "businesses and third-party websites". They keep your private data for as long as is "permitted under an applicable law". They promise to spam you with third party offers and to promote their own services and while you use their service they subject you to ads and let their "advertising partners" collect your data.
"Our advertising partners may also transmit cookies to your browser or device when you click on ads that appear on the Services...use tracking technologies with the Services. This may include the collection of information about your online activities"
If you go anywhere near that service read their privacy policy very very closely and make sure you know what you're getting yourself into.
