Silo Scan.

Paper in, searchable PDFs out.

Import a photo of a page, a scan, or an existing PDF. Silo Scan finds the page, straightens it, reads the text with Apple’s Vision framework on your Mac, and files a searchable PDF into a local archive you can search by what was on the page.

Not the data-broker tool. For opt-out letters, use Silo Scanner.

01 · Find the page, then read it

Straightened before it is read.

A photographed page is a quadrilateral, not a rectangle. Silo Scan detects the sheet, corrects the perspective, and reads the flattened result, so recognition sees a flat page instead of one photographed at an angle. The detected crop has draggable corners, and moving one re-reads the page.

02 · Searchable, not just scanned

The text goes into the PDF.

Every document is written with an invisible text layer over the page image. That is what makes it searchable in Preview, in Spotlight and in any other PDF reader, with or without Silo Scan installed. A scan without it looks identical and is useless to all of them.

03 · Named from what is on the page

Proposed, never decided.

A date, a document kind and an issuer are read off the page and offered as the filename. The rules are deterministic, so what they found is always explainable, and the proposal sits in an editable field until you file the document.

What it does
SC/01
Three ways in.

Drag files onto the window, import from the toolbar, or open one with Silo Scan from the Finder.

Images · PDFs
SC/02
Honest about what it found.

No page edge detected means the whole image is used and the app says so, rather than cropping through your text.

Vision · Core Image
SC/03
Full-text search over everything filed.

A local SQLite index searches the recognized text of every document, narrowing as you type.

SQLite FTS5
SC/04
Yours to take away.

Documents are ordinary PDFs in the app’s own container. Export a copy anywhere at any time.
