Most language learners hit the same wall. You decide to watch a show in your target language. Native subtitles and you stop processing the foreign audio. Target-language subtitles and you're pausing every ten seconds. No subtitles and you understand nothing. Twenty minutes in, you switch to something dubbed and don't try again for weeks.

Poliglotter is built around a different idea: progressive immersion. Instead of treating learning as a separate activity with drills and streaks, it treats it as a side effect of consumption. The system tracks your per-word exposure — how often you've seen each word, in what context, how recently — and continuously adapts the support layer over real content. Words you barely know are highlighted and scaffolded. Words you've seen enough times stop getting flagged because you no longer need the help. The assistance shrinks as your comprehension grows, automatically, without you managing anything.

It's not a flashcard app. It's not for absolute beginners. It's for people who already know that immersion is how they learn best, but who keep bouncing off the gap between "graded content is boring" and "real content is too hard."
