There are two things you need to do before pricing:
User Segment. You need to figure out who your users are. What is their goal by using your product? How much are they willing to pay for it? How much is the CAC? What's their LTV?
Valued Features. You need to figure out the key features they want, this would help you design the pricing tier.
PS: Make sure to grow with your users, the more value they receive, the more money you earn.
Happy to hear what's your thought.
