Desktop capture today, mobile review coming. One vocabulary system.

Capturing and reviewing are different activities that happen at different times. You meet new words while you're focused and reading — almost always at a desktop. You do your best reviewing in the small gaps of the day, often on a phone. A cross-platform vocabulary app should respect that split instead of forcing both onto one device, and that two-moments design is what Capecho is built around.

Capture lives on the desktop, where the words are. On your Mac, a single global shortcut reads the word and its sentence from whatever you're reading and keeps you in your flow, holding onto the exact sentence as the word's context. This is the shipped, working half of Capecho today; it's a real desktop vocabulary app you can use now, not a preview.

Today you also review on the same Mac: saved words return as FSRS spaced-repetition cards, each fronted by your own sentence, surfaced just before you'd forget. A dedicated phone companion for mobile vocabulary review is coming — built to turn commutes, queues, and idle minutes into short review sessions. It isn't shipped yet, so for now the whole loop runs comfortably on the desktop, with the phone as the next step rather than a current requirement.

Capecho is built so capture and review feed a single vocabulary system rather than two disconnected lists. When the phone companion arrives, sync will keep your words, the sentences you chose, and your review history in step, so the plan to sync vocabulary between desktop and mobile means one library — the same words and the same progress whether you opened them at your desk or on the train.

That single record is the point. Your captures aren't trapped on one machine waiting to be re-entered somewhere else; they're one growing library that compounds as you read.

Wherever you review, each word carries its meaning with it. Capecho's word explanation — core meaning, part of speech, distinct senses, pronunciation — is free and unmetered, and the meaning of the word in your specific sentence is metered at ten a day, free (unlimited on Pro). Because that understanding is saved alongside your sentence, a review tests the word the way you actually met it, not against a definition you never used.

Being cross-platform also means not locking you in. You can export your captured, context-rich cards to Anki or CSV anytime, with a target-language column so multi-language decks don't collide — Capecho is a complement to the review tools you already trust. The core loop is free, there's no subscription on it, and it's built first for English while never being English-only: other languages can be captured, saved, and reviewed today, with generated explanations expanding as their quality is validated.
