Capture the new words off any screen,
echo them back before they fade.
One keystroke to look up any word — even text you can't select. Save it, and Capecho does the rest, bringing each word with context back before you'd forget.
Now on Mac and iPhone · capture at your desk, review on the go
You look a word up. You understand it for one sentence. By the next page it's gone — so you look it up again, and again, and it never quite sticks.
The tools that capture won't help you remember. The ones that remember won't capture for you.
Capecho is the one that does both — it catches the word in the sentence you met it in, then echoes it back until it sticks. Not a replacement but a complement: keep your dictionary and your Anki deck; Capecho is the capture-to-review thread between them.

Capture uses on-device OCR — you edit or fix the word before it's saved.
From screen to memory,
in one shortcut.
Four steps, one keystroke. Catch the word with the line it lived in, see what it means, and let it come back on a schedule until you actually know it. There's no deck to build — catching the word already made the card.
Press ⌥E
macOS's on-device text recognition reads the word and its sentence from whatever you're reading — articles, PDFs, subtitles, images, non-selectable text — or copy first, then press. You edit the word before saving.
On-device OCR or clipboardMeaning, in context
A concise core meaning and part of speech, shown when it's ready — your save never waits on it. Senses and pronunciation sit behind a calm expand.
In-context gloss · optional, 10/day freeBefore they fade
Saved words come back as spaced-repetition cards fronted by your own sentence. Rate Forget / Hard / Good / Easy and each returns just before you'd forget it.
Review on Mac + iPhoneThe sentence is part of the meaning.
A dictionary gives you a definition that fits every sentence and none of yours. Capecho keeps the exact line you met the word in — so when it comes back, you remember which meaning was live, and where.
adjective — too great or extreme to be expressed or described in words.
a low, ineffable sense that the streets were holding their breath.
ineffable · adjective — too great or subtle to be put into words. Capecho keeps that meaning tied to the sentence you met it in, which is how it sticks.
Everything the loop needs. Nothing it doesn't.
- Off any screen, one keystroke
- A word in a PDF, a subtitle, a paused video, an image — press the shortcut and it's caught off whatever's on screen, even when you can't select the text. You never leave the page.
- The sentence comes with it
- Not just the word — the line you met it in, so you remember which meaning was live. You edit before anything is saved.
- What it means, right here
- A plain explanation — meaning, part of speech, how it sounds — and, when you ask, what the word means inside your own sentence.
- It comes back before you forget
- Every word turns into a review that resurfaces just in time. No deck to build — catching the word already made the card.
- Your words, not a word list
- Everything comes from what you actually read. No word-of-the-day trivia you'll never use.
- Never locked in
- One tidy Word Book, and one-click export to Anki or CSV. Your vocabulary is always yours to take.
Powerful capture you can trust.
Your Mac does the reading, not Capecho. At your keypress, it reads the text on screen and hands over only the words — the picture of your screen never leaves your machine. You see it, edit it, and decide what's saved.
- ·macOS's built-in text recognition does the reading — only at your keypress, never continuously.
- ·The system API returns only the recognized text — the screen image itself never reaches Capecho, so there's nothing to store and nothing to upload.
- ·You edit and confirm the word and its sentence in the preview before anything is saved.
- ·The word you save and the context sentence.
- ·Its explanation and your review history.
- ·The small settings that ride along (learning / explanation language).

Before you ask.
Will it slow my reading down? That's the whole point of one keystroke — you catch the word and its sentence without leaving the page or opening another app. Review happens later, on your own time.
What if I can't select the text? Subtitles, scanned PDFs, images, a paused video — Capecho reads what's on screen, so you can catch words you could never copy.
Is my screen recorded or uploaded? No. Your Mac reads the text at your keypress and hands Capecho only the words — the screen image never leaves your machine, and you edit before it's saved.
What does it cost? The core loop is free, with unlimited saved words. The only metered extra is the per-use in-context explanation — 10 a day free, unlimited on Pro ($6/mo or $48/yr). No subscription on the everyday loop.
