Sift: Read Any Book Faster

Bring your own PDF or EPUB. Choose the depth, read a clear condensed version, save the best ideas, and review them until they stick.

The books keep piling up. Sift helps you actually finish them.

Import a PDF or EPUB you own, choose how deeply you want to read, and start a clear condensed edition in seconds. Sift keeps the throughline of the source—not just a list of disconnected takeaways.

ANY BOOK—NOT A FIXED CATALOG

Bring the books already waiting in your files: nonfiction, fiction, textbooks, research, and long documents. Sift extracts text on your device, including scanned PDF pages with on-device OCR.

CHOOSE YOUR DEPTH

Move between six reading depths whenever you want:

• Gist — the core argument or arc • Quick — the essentials, fast • Balanced — the book, comfortably shorter • Deep — most of the detail, trimmed • Light — almost all of it, tightened • Original — every word as written

Sift shows an estimated reading time before you begin and remembers your place when you come back.

KEEP THE IDEAS WORTH REMEMBERING

While you read with Sift Pro, the app gathers striking, source-grounded ideas and organizes them on your Idea Shelf. Favorite the sparks that matter, then use quick spaced-repetition reviews to remember them. Optional reminders and streaks help turn reading into lasting knowledge.

READ YOUR WAY

• Page-by-page or continuous scrolling • Paper, sepia, and dark reading themes • Adjustable type size, width, spacing, and font • Condensed reads in English, Spanish, French, German, Portuguese, Hindi, Arabic, or Chinese • A focused reader built for iPhone and iPad

PRIVATE BY DESIGN

No account or login is required. Your imported files, reading progress, summaries, and saved ideas stay on your device. AI features securely send only the text needed for processing; on-device OCR images never leave your device. Sift does not sell your data, show ads, or track you across apps.

FREE AND PRO

Read the original text of your imports for free and try Gist or Quick condensation each day. Sift Pro unlocks every reading depth, unlimited AI condensation, and automatic idea gathering.

Bring the book you meant to finish. Sift what matters—and keep it.
