Fluenvo

This is the nice product.

Turning your own reading material into exercises is a strong angle, since learners stay more motivated when the content matters to them. The split between vocabulary, grammar and comprehension work built around one text is a good way to reuse the same material. I would be curious how it handles longer articles, and whether the exercises adapt when a learner keeps missing the same grammar point.

Practicing on articles I'd read anyway is much easier to stick with than textbook dialogues. Can you save the vocabulary pulled from one article and have it resurface later in exercises built from a different text?

Congrats on the launch! Practicing on material you actually care about is how most people really get fluent, so building exercises around your own content makes a lot of sense. Good to see something aimed at intermediate and advanced learners, too. That’s where most apps run out of road.

Turning material you already read into exercises is a smart angle, since the practice stays tied to content you actually care about. Do you support importing from a PDF or a URL, or only pasted text for now?

Using your own material instead of a generic course is the right default — a textbook chapter or a work handout usually teaches me more than a polished demo lesson. One question: when I drop in something long, does it split into exercises automatically or do I pick the focus (vocab, grammar, comprehension)? Also handy would be a way to keep a small library of past uploads so I can revisit a set of exercises a week later instead of re-uploading.

Building vocabulary and grammar exercises from articles I'd actually read anyway sounds like a great way to stay motivated past the intermediate plateau. Supporting both English and Spanish learners is a nice start. Are you thinking about adding more languages down the road?

Practicing on material you actually chose is a much better hook than generic lessons, especially at the intermediate level where textbooks get boring fast. Song lyrics would be a great source for this: learners already know the tune, which helps vocabulary stick. Can you paste a link (an article or a video transcript), or does it need the text copied in?
