A vocabulary notebook that keeps the context

A paper vocabulary notebook captures words but loses everything around them — the sentence, the source, the reason the word caught your eye. Capecho keeps all of it. Each entry holds the word, the exact sentence you met it in, an explanation of what it means, and a record of how well you remember it. The notebook stores the moment, not just the term.

That context is the difference between a list you skim and a notebook you actually learn from. Read back an entry weeks later and the sentence puts you right back where the word lived.

You fill this notebook the way it should be filled — by reading, not by transcribing. When a word stops you on the Mac, one keypress captures it together with its sentence, opens a preview you can edit, and saves it on confirm. No copying into a separate app, no manual page-keeping.

The captured word stays fixed, but the editable surfaces are the ones that should be: the context sentence and its gloss. You can tidy a sentence or sharpen a definition any time, so the notebook reads cleanly without ever falsifying the word you actually met.

The defining feature of a cross-platform notebook is that there is only one of it. Capecho syncs your entries to a single source of truth, so you are never reconciling two half-finished lists. Add a word, refine a sentence, finish a review on your Mac, and it lands in one canonical library — so on the iPhone companion it's the same notebook, not a second list to reconcile.

Review scheduling is server-authoritative too, so an entry's due date is consistent rather than drifting between devices. The notebook doesn't just hold the same words everywhere; it holds the same state.

A vocabulary tracker should track more than the words; it should track your grip on them. Capecho schedules each word with FSRS spaced repetition, so every entry also carries a review state — settled into memory, or due to come back soon. A glance across your Word Book tells you which words you have genuinely retained and which still need another pass.

That turns tracking into progress. Instead of guessing whether your vocabulary is growing, you can watch words move from fragile and frequently-due toward stable and rarely-due over time.

The notebook lives on your Mac, where you write entries by capturing and review them as they come due, and on your iPhone, where the same library comes back for review. The syncing library spans both devices — cross-platform isn't a direction, it's here.

The iPhone review companion covers the in-between minutes when reaching for your laptop isn't realistic. Because your notebook already syncs to the cloud, there's nothing to move — your entries and their review history are right there.

An ordinary notebook is passive — you have to remember to reopen it. Capecho's notebook brings its own entries back. Saved words return as FSRS spaced-repetition cards fronted by your own sentence, surfacing just before you'd forget them, so the act of keeping the notebook is also the act of remembering what's in it.

You rate each card Forget, Hard, Good, or Easy, and the schedule adjusts. The pages you'd otherwise let gather dust quietly move words into long-term memory.

A notebook you can't take with you isn't really yours. Capecho exports your context-rich entries to Anki and CSV whenever you want, with a target-language column so a multi-language notebook never collides. Keeping the notebook — capturing, unlimited saving, the explanation on each entry, and FSRS review on the Mac — is free, with no subscription on the core loop; the only optional upgrade is unlimited in-context explanations.

Capecho is built first for English and is never English-only, so the notebook is for whatever language you are reading and learning in — a record of everything you've met, kept in one place and ready to grow.
