Review vocabulary on the go

Capturing and reviewing are two different kinds of moment. Your best captures happen while you are focused and reading — at your desk, deep in an article, a PDF, or a video. Your best reviews happen in the gaps: the commute, the queue, the minute before bed. Capecho is built so neither moment is wasted and the words flow from one into the other.

The full loop runs on the Mac right now. You capture a word with one keypress, Capecho keeps the sentence you met it in and explains it, and the same app brings it back as a spaced-repetition review when it comes due. You do not need a second device to start remembering words — the on-the-go habit begins with a queue you can already work through on your computer.

A phone companion for review is on the way, designed for exactly those in-between minutes when you would otherwise be scrolling. It is the 'echo' half of Capecho — the place to meet your captured words again away from your desk.

It is not shipped yet, and we would rather tell you that plainly than imply an app that isn't here. What you can count on today is that the system is being built for it: capture is grounded on the Mac, and review is meant to travel.

Everything you capture syncs to a single cloud library, and FSRS scheduling is server-authoritative — one source of truth decides when each word is due. That means the moment the phone companion arrives, the words you have been saving and the review history behind them are ready to sync to it, due dates intact, with nothing to export or rebuild.

Because the schedule is consistent across devices, a word you rate on one screen stays correctly timed everywhere. On-the-go review will pick up exactly where your desk left off.

Review in Capecho is short and self-paced, never a heavy block of study. A card shows your own sentence with the new word highlighted; you rate how well you knew it — Forget, Hard, Good, or Easy — and spaced repetition sets when you will see it next. A handful of cards is a complete session.

There is nothing to set up before you begin. Because each card was captured with its context and explanation already attached, the words are simply waiting when you are, whether that is a full minute or a stolen thirty seconds.

The whole point of review is timing. FSRS models how your memory of a word decays and brings it back just before you would forget it — soon for the words that won't stick, later for the ones that already have. Fragile first encounters become durable memory without you having to plan a single thing.

Capecho is built first for English and is never English-only, so the words you carry into your spare minutes are the ones from the language you are actually trying to learn.
