Hook Book

Turn ad inspiration into sharp copywriting. Hook Book is a personal, private offline swipe file for capturing the ads that stop your scroll, uncovering what makes them work, and practicing your own headlines and body copy. Most ad screenshots disappear into a crowded photo album. Hook Book keeps your creative inspiration organized, structured, and actionable: • 3-SECOND CAPTURE Snap an ad screenshot and record why it caught your eye before you forget. • HOOK ANGLE TRIAGE & VISUAL DISTRIBUTION Group and tag your ads by angle—Urgency, Social Proof, Curiosity, Problem-Solution, and more. Visual charts show your breakdown at a glance. • COPYWRITING PRACTICE MODE Turn passive observation into active writing skill. Use any saved ad's angle as a launchpad to write, duplicate, and refine your own headline and body copy variations. • 100% OFFLINE & PRIVATE Hook Book requires no account, no login, and no internet connection. All screenshots, notes, and drafts live exclusively on your device. Zero tracking, zero SDKs, zero ads. • NATIVE SHARING Easily share your ad inspirations or written copy drafts directly via the native iOS share sheet.
