Show HN: Listen to PDFs in Any Language

Hey, I built this tool last year to listen to machine learning books and papers. The first version was very simple, but I saw some interest from users and found myself using it regularly whenever a new machine learning paper was published.

Now, after a year and over 3,000 signups and some paying users, I've invested more time into it, with the help of AI programming :) During that year I've switched to the newest models, which made the app smarter over time. I’m curious what you’d use it for.

Do you like the AI explantions? This is my favorite feature, but most users prefer listening to the original text. Sometimes the AI explanations are a bit repetitive, and I'm working on improving that.

Currently, I’m creating RSS podcasts so I can listen to the episodes on my phone using AntennaPod. But I think the next step is to make an app.

Google Gemini now offers Audio Overviews, which are quite good. However, my app is different because it breaks the document into semantic sections and you can listen to each section independently. A whole paper will be a multi-hour audio, like an audio book. The audio experience is the product.

I would love your feedback (I even made a form for that on the website).
