A link to read later. A task you can't forget. An idea that just popped into your head. Do you keep each of these in a different app? ThinkCapture is one place to drop all three. You don't pick where things go: whether it's a link, a task, or a passing thought, the AI on your device reads it and files it. You never classify. You never tag. You just write. ■ Three apps, in one - Links to read later — send a URL from the share sheet; it's saved with a headline and thumbnail. - Things to do — write "reply to Sam" or "buy milk" and the AI treats it as a task; add a due time and it reminds you. - Ideas and notes — thoughts, things you've learned, and what happened today all go in the same field, and they stay. ■ Why keep them together Storing things separately means deciding, every time, which app this belongs in — enough friction that you often don't write it down at all. Put it all in one place and it becomes impossible to find. Make sorting the AI's job and both problems disappear — and since the sorting never leaves your device, you can pile up anything without worrying. ■ What you can do - Instant capture — write in a single field; saving finishes at once, without waiting for the AI. One tap from Siri, Shortcuts, widgets, or Control Center. - On-device sorting — each note becomes a task, idea, knowledge, reference, journal, waiting, or someday item. Override any result; when it isn't sure it says "unclassified" instead of guessing. - Full-text search — find anything by keyword or tag name, completed items too. - Today — no cluttered inbox. Just today's tasks and your recurring habits. - Calendar — see the days you wrote on, and overlay events from your device's calendar (iCloud, Google, and more). Events are displayed, never changed. - Tags and priority — add your own tags on top of the AI's categories, and set high, medium, or low priority. - Due dates and reminders — set one in a tap; add a time and you get a notification. Recurring reminders too. - Photo attachments, plus a grid layout like paper in a notebook. - Home Screen widget — check today's tasks and capture without opening the app. - Backup and restore — export everything as JSON or Markdown anytime and import it back; restoring merges, never deletes. - iCloud sync (optional, off by default) — only about where data is stored; sorting still runs on device. ■ Pricing Writing, sorting, searching and exporting are free, with no limit on how much you capture. Everything above stays free and unlimited. ThinkCapture Pro is an optional subscription for how the app looks and where it lives: color themes (green, blue, purple), a board view that flips through your Inbox column by column, and a Lock Screen card for checking off today's tasks. In Japan it is ¥2,500 per year (about ¥208 a month, roughly 48% less than monthly) or ¥400 per month; your region's price is shown in the app. The yearly plan starts with a 14-day free trial for people new to the subscription. Both plans renew automatically unless cancelled at least 24 hours before the period ends, and you can cancel anytime under Settings > your Apple Account > Subscriptions. Without Pro, nothing is locked away and nothing stops you from writing more.

What you write is never sent to an outside server to be classified, and no account is required. Saving a link fetches only that page's public headline and thumbnail. ■ Requirements Automatic sorting requires iOS 26 or later on an Apple Intelligence–capable device. On other devices you tap the classification badge to pick a category by hand — it still works as an ordinary notes and tasks app. Don't classify. Don't organize. Just write.

About

Keepout

Features
Read full description

Keepout is a private notes app for iPhone and iPad. Your writing stays on your device, encrypted at rest, with local tools for connecting and understanding ideas. PRIVATE BY DESIGN • AES-256-GCM encryption protects every note at rest. • Your vault key stays in this device's non-synchronizing Keychain. • Opaque filenames keep note titles and links out of the file system. • There is no account, cloud sync, analytics, remote prompt processing, or plaintext search index. CONNECTED KNOWLEDGE • Link notes with familiar double-bracket wiki links. • Follow backlinks and suggested related notes. • Explore an interactive knowledge graph built with Apple's local sentence embeddings. • Search decrypted notes in memory while the vault is unlocked. LOCAL AI • Ask questions, summarize a note, and suggest connections without sending note text to a server. • Use Apple Foundation Models on supported devices. • Choose the optional MLX engine for local inference. Its compact model downloads once on first use; inference then stays on your device. FOCUSED WRITING • Open the transient action bar from the toolbar or with Command-K on a hardware keyboard. • Type / in the editor for headings, lists, tasks, quotes, code blocks, dividers, and links. • Switch to a centered typewriter view that hides the side columns and softly fades the page edges. • Navigate with touch or hardware-keyboard shortcuts on iPad. • Markdown syntax and link destinations stay visually quiet until the caret enters them. Keepout stores each encrypted note in a .md file so your vault remains a collection of Markdown documents without exposing their contents at rest.
