How to Crop a Screenshot on iPhone in 3 Seconds

Screenshots as Knowledge Capture

Cropping removes irrelevant context before saving a screenshot to your knowledge system. This matters for searchability: a full-screen screenshot of a browser with UI chrome, bookmarks bar, and notifications has OCR content that dilutes the core information.

Crop to the specific element worth capturing: the chart, the highlighted text passage, the UI component, the data table. Then share to Nemos.

The workflow: take screenshot → markup editor opens automatically → crop → tap Done → immediately share to Nemos via the share icon. Add a voice note with context before saving. This two-step process (crop, then annotate context) produces high-quality captures that remain useful months later.

For text-heavy captures: crop to include only the specific passage you need. OCR indexes that passage directly without having to find it in a full-page screenshot.
