Keepout: Private Notes

Keepout is a private notes app for iPhone and iPad. Write and connect ideas in an encrypted vault on your device, with optional sync and connections you choose to enable. PRIVATE BY DESIGN • AES-256-GCM encryption protects every note, saved AI memory, and imported AI secret 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. • Core note writing works without an account or network connection. • Choose whether to pair devices for encrypted note and clipboard sync. 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. AI AND CONNECTED FEATURES • Ask questions, summarize a note, and suggest connections using Apple Foundation Models on supported devices. • Search encrypted chat memory by meaning with Apple's local Natural Language embeddings. • Local AI availability depends on device support and Apple Intelligence settings. • If you configure a networked AI provider, requests can send prompts and relevant context to that provider. • Optional Writing Tools can send selected text to Apple's services; leave them disabled to avoid that editor connection. • Publish a note to your own Microfeed site with your site's API key. FOCUSED WRITING • Open the transient action bar from the toolbar or with Command-K on a hardware keyboard. • Press Command-F on a hardware keyboard to search private chat memory semantically. • 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. OPTIONAL DEVICE CONNECTIONS • Pair your own devices to sync encrypted notes through a relay while Keepout is open and unlocked. • Enable encrypted clipboard sync for paired devices. On iPhone and iPad, use the Paste control to send text. • Optionally index note titles and tags in protected on-device Spotlight search; the index clears when the vault locks. Keepout stores each encrypted note in a .md file so your vault remains a collection of Markdown documents without exposing their contents at rest.
