Brainbank is your AI second brain — the simplest way to save anything and actually find it later. You screenshot recipes, places, products, links and reels all day… and never see them again. Brainbank fixes that: save anything and it reads, understands and files it for you, so your camera roll stops being a graveyard. Brainbank is a subscription app. A Brainbank Pro subscription is required to use the app and unlock the full AI library. HOW IT WORKS • Save from anywhere — screenshot something, or share a link, reel or photo from any app straight into Brainbank. • It reads every save — on-device AI turns each screenshot into structured info: a recipe with its ingredients, a place with its address, a product with its price, a link you can reopen. • It sorts itself — saves are auto-filed into shelves like Recipes, Places and Products, plus your own shelves (Japan, Air fryer, anything). • Find it in seconds — search by meaning, not folders. Add your own note to any save so it surfaces the way you remember it. WHY BRAINBANK • Understands your saves — Photos and Instagram just store pixels; Brainbank knows what's in them. • Private by design — your library lives on your device. Your saves are yours. • You're in control — one tap to fix or re-file anything the AI gets wrong. • Calm and warm — a clean, playful library that's a pleasure to open. Stop saving things you'll never find. Start building a second brain that remembers for you. SUBSCRIPTION Brainbank Pro is required to use the app and unlocks the full AI library: • Monthly — $14.99 per month • Yearly — $49.99 per year (includes a 1-week free trial) Prices may vary by region. Payment is charged to your Apple ID account at confirmation of purchase. Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings after purchase. Terms of Use (EULA): https://1rie.ink/app/terms Privacy Policy: https://1rie.ink/app/privacy/
