LLM summaries are basically free, its the TTS where the costs add up. Currently its ~.03 cents per episode. That is a number I've been happy with while running our beta testing. I found that power users were eating up nearly all or sometimes a tiny bit more than $5/month in costs but on average users were typically under that putting me in profit.
There is still a lot more optimizations that I have planned to bring that TTS cost down more. With scale I think I would buy out server space for running TTS models but at current volume API makes more sense and is not cost prohibitive to me.
Thank you for the comment - based on your feedback we have enhanced a bit the experience for users without logging in.
Now on the landing page users are able to input cards to their liking and compare them at different vendors/categories to determine the best card without login.
