Track the words you actually meet

Most vocabulary trackers hand you someone else's list and ask you to work through it. Capecho inverts that. Your tracker — the Word Book — fills with the words you encountered yourself, while reading the things you already read. Each entry is a word that mattered enough to stop on, not a row from a curriculum you didn't choose.

Because you curate it simply by reading and capturing, the tracker stays honest to your actual life: the article, the documentation, the subtitle where the word first appeared. It is a record of your reading, kept automatically.

A word on its own is just a row. In Capecho, every tracked word carries the exact sentence you met it in, so the entry preserves the moment, not only the term. Alongside it sits the word's explanation — meaning, part of speech, and senses — so the record is something you can actually understand later, not a cryptic note to your past self.

The captured word is fixed, which keeps the record trustworthy, but the context sentence and its gloss stay editable. If a sentence reads better trimmed, or a gloss could be clearer, you refine the surfaces around the word without losing the word itself.

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.

Vocabulary is cumulative, and so is this. Re-meeting a word in a new sentence adds to its history rather than overwriting what came before, so the entry deepens as your reading does. Over months, the tracker becomes a layered record of how you came to know each word — something no generic app, working from a fixed list, can reproduce.

Today the tracker lives in the Mac app, where you both capture words and review them as they come due — the complete loop in one place. Your library syncs to a single source of truth, and a phone review companion is coming for the in-between minutes of your day.

When that companion arrives, the tracker you have built — every word, every context, every review state — is ready to sync to it, with nothing to migrate. The record you keep on your computer becomes the record in your pocket too.

A tracker is only as good as your ability to take it with you. Capecho exports your captured, context-rich words to Anki and CSV at any time, with a target-language column so a multi-language record stays cleanly separated. Your vocabulary belongs to you, not to one app.

Building the tracker is free: capturing words, the explanation on each entry, and FSRS review on the Mac carry no subscription on the core loop; Pro is the optional upgrade for an unlimited library. Capecho is built first for English and is never English-only, so it tracks the language you are actually learning.
