Review words before they fade

Spaced repetition is the most reliable way to remember more in less time: instead of cramming, you meet each word again at widening intervals, right at the edge of forgetting. The catch has always been card creation. Sitting down to type out words, definitions, and example sentences is the chore that quietly kills most people's review habit before it starts.

Capecho removes that step entirely. Every word you capture while reading is already a review card, complete with the sentence you met it in and a free explanation of what it means. There is no manual card-building, no formatting, no separate authoring session — the words arrive ready to review.

A bare word-and-definition pair teaches you the card, not the word. Capecho fronts each review with the exact sentence you captured, the new word highlighted inside it, so recall is grounded in the meaning and the moment you first encountered it. You are not recognizing a flashcard you have seen fifty times; you are re-reading the sentence that made the word matter.

The captured word itself is fixed, but the surfaces around it stay yours to refine: you can edit the context sentence or its gloss whenever the meaning could be sharper. The card improves with you instead of freezing at first capture.

Capecho schedules reviews with FSRS, a modern spaced-repetition algorithm that models how memory actually decays. After each card you rate it Forget, Hard, Good, or Easy, and FSRS uses that signal to predict when you would next be on the verge of forgetting — then surfaces the word just before that point. Words you find hard come back sooner; words you know well drift further out, so your time lands where it does the most good.

The scheduling is server-authoritative, which means a single source of truth governs when every word is due. As your library follows you across devices, the timing stays consistent rather than drifting out of sync.

Right now the whole loop lives on the Mac. You capture words from whatever you are reading, Capecho explains and saves them, and the same app brings them back as FSRS reviews when they come due — capture and review in one place, no second device required to get value today.

A phone review companion is coming, built for the in-between minutes of your day. Your words and review history already sync to the cloud, so the moment that companion arrives, the queue you have been building on the Mac is there waiting — nothing to migrate, nothing to rebuild.

Capecho and Anki share the same underlying idea, and you do not have to choose between them. If the friction of building context-rich cards is what stops you, Capecho closes that gap by capturing and explaining words in context automatically. If you would rather review somewhere you already trust, Capecho exports cleanly to Anki and CSV at any time, with a target-language column so multi-language decks stay separate.

The point is to remove the work in front of spaced repetition, not to lock you into one home for it. Capture and understand in context here; review wherever you like.

The core loop — capturing words, the word explanation with meanings, part of speech, pronunciation, and FSRS review on the Mac — is free and unmetered, with no subscription on the core loop — Pro is the optional upgrade for unlimited saved words and unlimited in-context. On Free, the deeper in-context explanation that interprets a word inside your specific sentence is metered: ten of those a day, free, and reaching the cap never blocks capturing, reviewing, or anything else.

Capecho is built first for English, the language it validates quality against, but it is never English-only — the same capture-and-review loop is designed to work for the language you are actually learning.
