Nuance was a tool to help you learn Spanish by reading books.
When GPT advanced voice came out I decided to scratch an itch I had had for many years. To learn spanish reading books.
I prompted it to translate as a read outloud so even if my spanish was not good I could understand the story and get lots of repeititon.
It worked fantastic so I decided to build a full app around the ideas.
Got the product working good but spent months without getting any meaningful user traction.
Shut it down in July 2024.
