Monolithos Core

YOUR PERSONAL AGENT STARTS WITH MEMORY.

Monolithos connects your knowledge, writing and AI work in one local-first workspace. We are building a Personal Agent OS that remembers your context, helps move work forward and keeps you in control. Your memory is the foundation. What you do with it is the point.

Bring your own Markdown vault. Turn notes into knowledge, meetings into next steps, and ideas into finished work. Your files remain yours to inspect, edit and take with you.

MEMORY THAT BELONGS TO YOU

- Two layers: Crystals organize what you know; a personal memory layer captures your preferences, judgment and patterns.
- The Mirror: inspect how AI understands you, trace traits to their sources, and adjust or remove them.
- Night Watch: discover connections and proposed memories from your work. You decide what to accept.
- Recall: find relevant knowledge through keyword, graph and semantic retrieval, with sources you can inspect.
- Private Domain: choose folders to exclude from cloud AI context while keeping them available for your own local work.

FROM IDEAS TO ACTION

- Flow: run multi-step AI tasks for research, writing and finished work. Steps that require your judgment pause for approval.
- Black Hole: collect material through capture tools and the iPhone share sheet, then bring it into your workspace.
- Minutes: record and transcribe on-device, separate speakers after recording, review insights and save Markdown meeting archives. Turn follow-up items into AI tasks.
- Synapse: use AI actions on selected text, with access to multiple model families through one interface.
- Deep Research: investigate a question across multiple steps and bring the findings into a structured report.

CREATE, NOT JUST CHAT

- Codex: write and edit Markdown, organize files and work directly with your own material.
- Prism: a four-agent presentation workflow with 126 layouts and 14 themes. Turn Markdown into decks you can refine and present.
- Audio Brief: turn documents into podcast-style audio in four formats across 12 languages.
- Projects: keep related material and AI work within a defined scope.

LOCAL-FIRST, WITH CLEAR BOUNDARIES

Your vault is stored on your device as Markdown and YAML, without a proprietary file format. It is Obsidian-compatible, supports multiple vaults, and can sync between Apple devices through iCloud.

Local-first does not mean every AI operation is offline. Cloud AI processes the context needed for the tasks you request. Private Domain content is excluded from cloud AI context.

Minutes audio stays on your device. Live insights send transcript text to cloud AI; turning insights off stops further live analysis. Generating a summary sends the full transcript for cloud processing.

Search your files with fast, Rust-native full-text search, including Chinese, Japanese and Korean. Use the interface in English, Simplified Chinese, Traditional Chinese, Japanese or Korean.

BUILT AROUND YOUR WORK

For researchers, writers, founders and anyone building knowledge over time. Keep your materials, develop your thinking and put AI to work without giving up ownership of what you create.

Your memory. Your decisions. Your agent.

Local file management, search and Markdown editing do not require an AI subscription. AI features require a subscription. Plans and pricing are available in Settings.
