Need some guidance on AI SaaS product conversion rates

Long story short - my product trimmr.ai (https://www.trimmr.ai) recently launched and I've been so happy with the users and sign-ups. The problem is - we're at about a 1% conversion rate from free to paid customers.

A thought we had was maybe the free tier was too good and users wouldn't want to upgrade. We also thought that users might need more time on the platform or maybe even some manual nurturing.
