Show HN: Clarisu – Create educational podcasts

Hey HN,

I’ve built Clarisu, an app that generates short educational podcasts from any topic you give it: https://clarisu.com

It started from https://pdftomp3.com, a tool I made to turn PDFs into audio. I mostly used it to listen to AI papers, but I still had to download the MP3s to my phone. So I made an app instead!

Now you just enter a topic in a textbox, and it builds a “podcast episode” with paragraphs and chapters. It has a “Clarify” button which goes deeper into a topic. This is where the name comes from :) I think I’ve learned a lot of new things by listening to my own episodes!

Next up: adding PDF uploads directly into the app.

I would love your feedback!
