Monolithos Core
Read full descriptionHide full description
Monolithos is a sovereign Life Operating System — an AI-powered workspace built on the conviction that your memory is the only moat that matters. Your notes, your ideas, your intellectual output: entirely, permanently yours. Unlike cloud tools that mine your data, Monolithos is local-first. Your Markdown vault lives on your device, in plaintext you control. Your vault never leaves your device — our servers route AI calls, they do not keep your files. A MEMORY THAT IS ACTUALLY YOURS This release makes Monolithos a true Memory OS: - Dual-layer memory: Crystals capture what you know; a soul layer learns who you are — your judgment, taste, and thinking patterns - The Mirror: see exactly how the AI understands you, trace every trait to its source, tune or delete anything - Night Watch: the AI distills your work overnight — but only proposes; nothing enters your memory without your approval - Instant recall: three-layer retrieval (keyword, knowledge graph, semantic) with full CJK support, every result carrying its source and confidence — the AI shows you why it believes what it says - Private Domain: designate folders only you and on-device processing may enter. Cloud AI stops at the boundary. Always. AI THAT ACTS, WITH YOUR PERMISSION Frontier models — Gemini, Claude, Grok — behind one intelligent router: - Flow: multi-step AI orchestration that runs long tasks in the background, survives restarts, and pauses for your approval before anything consequential - Black Hole: throw in anything from anywhere — share sheet, capture panel, Live Activities on iPhone — and watch it fall into order - Minutes: record meetings, transcribe, extract insights, seal them into permanent Markdown archives - Synapse (Cmd+J): summon instant AI actions on any selection - Deep Research: multi-step investigations synthesized into structured reports CREATE AT STUDIO GRADE - Prism — The Black Stone Press: a four-agent presentation engine (Director, Copywriter, Reviewer, Visual Designer) with 126 layouts and 14 themes that turns Markdown into publication-ready decks - Audio Brief: transform any document into podcast-quality audio in four signature formats across 12 languages YOUR VAULT, YOUR RULES - Pure local Markdown + YAML frontmatter — no proprietary formats, no lock-in, Obsidian-compatible - Projects: scoped workspaces that keep AI inside the boundary you draw - Rust-native full-text search (Tantivy) with CJK support - iCloud sync between Mac and iPhone; multiple vaults - Interface in English, 简体中文, 繁體中文, 日本語, 한국어 BUILT FOR PEOPLE WHO THINK FOR A LIVING Monolithos is not a note-taking app. It is an operating system for sovereign minds — researchers, writers, strategists, founders, and anyone who refuses to let a corporation own their cognitive output. Your mind is sovereign. Your vault is yours. The Monolith is merely the tool. Subscription required for AI features. Plans and pricing available in Settings.
