Show HN: AI Reading Companion

hey all - i have been using gpt to read books for about a year now. It's been solid but I wanted:

1. something sleeker, in one app with all the e-reader capabilities 2. something more context aware.

i've been hoping kindle would build some ai features, but they're lagging, so i built a ai-powered web e-reader called flow.

from the technical side i create semantic embeddings for the entire book as well as analyze it with an llm on upload (key arguments by chapter, historical context etc). i then use basic rag architecture to pass the right data at the right time to power all the features.

currently its built for complex non-fiction content, but thinking about making it work well for complex sci-fi / fantasy books.

check it out, would love thoughts and feedback.
