Unfortunately, our upstream costs to the LLM providers are fixed, which means we can’t offer any kind of discounting at this time, as we still have to pay our own bills!
The $20/month price plan is a very deliberate choice to try and keep the cost low enough that people can sign up, but high enough that we can still provide a solid amount of AI queries as part of the plan.
As a temporary workaround, you may want to use an API key, as this would mean you get charged only for what you use. But you do run the risk of spending more than $20 on this, if you are a power user.
