Share anything you want to keep from Instagram, TikTok, X, YouTube, Reddit, the web, PDFs and screenshots, and Clarity reads it, sums it up and files it into your areas. Find any save later by describing what you remember, see how your ideas connect on a visual map, and let Claude or ChatGPT search your second brain through a connector. SAVE FROM ANY APP • Share a link, image or file to Clarity from Safari, Mail, Photos or any app with a share button. • Hold + and talk. Voice notes are transcribed on your device, and a tap on any word plays the recording from there. • Saved links open back in the app they came from. FIND THE THING YOU HALF REMEMBER • Search the way you remember it: "the dentist invoice", "that talk about sleep". Results that are close in meaning show up too, not only exact words. • Every result says why it matched. • Text inside images is read on your device, so screenshots of receipts, slides and notes are searchable. SEE HOW IT FITS TOGETHER • Your saves sit on a canvas, coloured by the area of life they belong to and connected to related saves. COPY WHAT YOU REUSE • Tap a card, then Copy, and the text is on your clipboard. • Blanks: write {name} or {date} in a note and Clarity asks for the value before it copies. SHOW A DOCUMENT • Import PDFs and other files from Files, the share sheet, or drag and drop on iPad. • Preview any format with Quick Look, or share it on. • Present fills the screen with the document and nothing else, so you can turn your iPad to a client and swipe through the pages. • Clarity reads the text inside your documents on your device, so a phrase from page 12 finds the file. MADE FOR IPHONE AND IPAD • Shortcuts actions: Copy Snippet, Find in Clarity and Save to Clarity. Run them from the Shortcuts app or with Siri. • Home Screen widgets copy a saved note in one tap. • On iPad, keep Clarity in Slide Over next to Mail, or side by side with any app, in any orientation. YOURS, ON YOUR DEVICE • Everything you save is stored on your device. There is no account to create. • Signed in to iCloud, your library syncs between your devices through your own private iCloud. • Export everything at any time, including as an Obsidian vault. WHAT IS FREE AND WHAT COSTS EXTRA • Saving is free and unlimited, and every feature that runs on your device works without paying. • Clarity Plus is an optional subscription at £4.99 a month or £39.99 a year, or the equivalent price in your country. The yearly plan starts with a 7-day free trial. It adds the online AI features: 1,000 AI summaries a month, connecting Claude or ChatGPT to your library, and checks for which saves really connect. • The subscription renews automatically at the end of each month or year until you cancel. If you start the free trial, the yearly price is charged when it ends unless you cancel at least 24 hours before. Cancel at least 24 hours before the renewal date in Settings > Apple Account > Subscriptions. Payment is charged to your Apple Account. • Searching, copying, presenting, exporting and deleting never need Clarity Plus. • The AI features are off until you turn them on, and Clarity asks first. For a summary, the link goes to our server, where Cloudflare Workers AI writes it. For connection checks, a save's title and some of its text go to our server and on to Jev, from TypeSafe.
