Fluenvo
Turn any text you're reading into a language lesson
Fluenvo turns any text you're already reading - an article, a book chapter, a video transcript - into a personalized lesson: grammar, vocabulary, and comprehension exercises built from that exact content, not a generic script. It tracks your weak spots and keeps bringing them back, explains mistakes with context, and saves new words into spaced-repetition review. English and Spanish, built for intermediate/advanced learners who've outgrown beginner apps.
Hey Product Hunt, I'm Ilya, solo builder of Fluenvo.
I kept bouncing off language apps that taught from decks of someone else's example sentences - stuff I didn't actually care about. So I built the thing I wanted: paste in a text, article, video transcript, or song you're genuinely interested in, and Fluenvo turns it into a full lesson - grammar, vocabulary, comprehension exercises - built from that exact content, not a script. It tracks what you keep getting wrong and brings it back, explains mistakes with context instead of just marking them red, and saves new words into spaced repetition.
Built for intermediate/advanced learners, English and Spanish - not another beginner app.
One honest note upfront: there's no free trial. Running AI analysis on your own material costs real money on my end, and as a bootstrapped solo dev with no investors, I can't subsidize that for free accounts the way funded apps can. Pricing is pay-per-analysis or a flat Premium tier - I'd rather say that plainly than pretend otherwise.
Would genuinely love your feedback, especially: do the exercises feel useful, or like busywork? And is "intermediate/advanced only" the right scope, or too narrow?
