Thank you for building this! I've been looking for something like this and even tried to build some for myself. As a non-developer, I've only been able to port some existing services and use very rudimentary structures.
What I like about the chat-style interface is that I can always write little pieces that are easy to send, but hard to edit afterwards. It forces me to keep writing and sending, rather than stopping at a sentence and rethinking the wording and getting halted. I'm actually writing thesis and scientific papers this way.
I'm curious about the data storage: I noticed that you mention data is stored in SQLite database. Can you share the path?
