A look inside the app.
Your text stays yours.
CaptureToComprehend runs entirely on your iPhone. It works with no internet connection, collects no data, and never uploads your images or scans anywhere.
Questions, answered.
Does it need an internet connection?
No. All text recognition happens on your device using Apple's Vision framework, so CaptureToComprehend works fully offline — even in airplane mode.
Are my images or scans uploaded anywhere?
Never. Your images are processed locally and stay on your phone. There are no servers receiving your data, no account, and no tracking.
What can I capture text from?
Documents, books, receipts, signs, labels, screenshots — almost anything with printed or clearly written text. You can capture from the camera live, snap a photo, or pick an image from your library.
Can I export or reuse the text?
Yes. Copy it to the clipboard with one tap, share it to any app, or export your scans as PDF documents. Your scan history is kept on-device for quick access.
Does it support multiple languages?
Yes. Recognition uses Apple's Vision framework, which supports text detection across multiple languages.
