Any plans to go beyond podcasts? I'd like to import any EPUB, PDF or TXT document, have it read to me by text-to-speech, and then have all the features you currently have for podcasts (i.e. reading along on the screen, one-tap highlights, etc.).
For now, we haven't really thought about enabling text mediums and going the other way around (text to speech instead of speech to text). You could however check out the Matter app. Not sure whether you can upload your own pdfs, but you can do text-to-speech for blog posts, including highlighting. They also have a Readwise integration like us.
And I really like your one-tap highlight functionality (or triple clicking the headphone buttons). Very useful when driving or when the phone is tucked away and you're listening via headphones.
