Keepout: Private Notes

Private notes with encrypted markdown, connected ideas, and on-device AI. No account, cloud sync, analytics, or remote prompt processing.

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.
