Keep every line worth keeping.

Scan quotes from real books, build a beautiful highlight library, remember them, and share them as cards.

What Keepline does

• Scan a page — point your camera at a printed book page; Keepline pulls out the text.
• Pick the sentences — tap the lines worth keeping; they're saved to the right book.
• Remember & share — revisit highlights with spaced repetition and turn them into shareable cards.
• Yours to keep — export your whole library to Markdown or CSV anytime. No lock‑in.

Tap the ＋ button, photograph the page (or pick one from your gallery), tap the sentences you want, edit if needed, then save it to a book.

An optional auto‑renewable subscription (Monthly or Yearly — no free trial) that unlocks all card templates without a watermark, cloud sync across devices, Kindle import, advanced stats, and AI answers over your own highlights.

Open your device Settings → your name → Subscriptions (or the App Store account settings) and manage Keepline there. Deleting the app does not cancel a subscription.

Email enesgencad@gmail.com from your account address and we'll delete your account and synced data within 30 days. Local data is removed when you delete the app.

Keepline is local‑first; sync and AI are optional. Scanned photos are processed only to extract text and then deleted. See our Privacy Policy.

OCR works best on a flat, well‑lit page. After scanning, you can fix any text on the edit step before saving.
