lecteuraide is a french reading companion for long PDFs. you give it a book, it segments it into scenes, translates every sentence, extracts vocabulary, and generates comprehension questions, then presents everything in a purpose-built reading interface. i built it because looking up words one at a time was really painful.

what i built

fastapi backend for book upload, scene segmentation, translation, vocab extraction, and persistence
next.js frontend for uploading, browsing the library, and reading scene by scene
vertex AI and google cloud translation pipeline that turns raw PDFs into guided reading experiences

findings

passing the previous scene's summary forward is what keeps the narrative coherent across chunks

what's next

record a walkthrough video of the scene-by-scene reading flow
build out stronger review and spaced-repetition loops in the reader
