The prospectus
Your knowledge, tracked like a portfolio.
Most apps give a word a checkmark: “learned”. But memory doesn't work like that — it fades. So every word you save gets a live price instead. Answer well, and it rises. Leave it alone, and it melts. Your job is simple: keep the portfolio green.
Live prices
Every word has a price that shows how well you know it today — not last month. Stop practicing, and it slowly melts. Just like real memory.
Sessions pick themselves
Press Study and get the words that need you most — melting ones first, never more than 20. Five minutes, and your portfolio is green again.
Listening counts too
Finish a podcast episode made from your words, and every word you have studied gets fresher. Even a walk moves your portfolio.

Learn it with your agent
Your agent, your broker.
You just saw our AI build a deck from a topic. Your own agent does the same job — better, because it already knows you. Connect your Codex, your Claude, or another, and it builds your decks straight from your real life, right into Lingvestor.
You write, as usual
An email, a trip plan, a chat in your new language. You talk to your agent the way you already do.
It picks the words
Your agent knows your level and the phrases you got stuck on. It shows you the list — you cross out what you don't want.
The deck appears
You approve, and a ready deck shows up in Lingvestor, with cards built from your own sentences.
Your conversations stay with your agent — you approve every word before it is saved.
