Kompas AI is a desktop thinking tool for macOS and Windows that turns your reading, notes, and AI chats into a connected graph you can write from.
About Kompas AI
What Is Kompas AI
Kompas AI is a desktop app that works as an AI writing companion and a note-taking app at once, built for people who think and write for a living. It stores your notes, highlights, voice memos, and documents on your own machine, links them into a graph, and lets you start a session on any topic to work through it.
The problem it targets is forgetfulness, not lack of tools. Most people read more than ever and talk to AI all day, yet almost none of that thinking stays in one place. This knowledge graph app treats every session as a trace you can find again, connected to what you wrote before.
The tradeoff is that Kompas AI lives only on the desktop. There is no web version, and the free tier runs a single device. Sync and managed AI require a paid plan. It is also young software, still shipped as a 0.x release, so the feature set keeps changing.
Getting Started
- Download the free app for macOS (Apple Silicon or Intel) or Windows and install it.
- Capture material by importing documents, highlights, web pages, or voice notes. Everything is marked as yours before it's processed.
- Start a session with a topic. Kompas AI pulls in your past notes and reading to ask sharper questions back.
- Move a finished session into a draft. Past work surfaces only when it helps, so the writing stays yours.
- Export everything to JSON whenever you want, on either tier.

Best for
The users, tasks, and scenarios where this tool fits best.
Users
- Essayists who want drafts that carry their own argument, because Kompas AI remembers their past writing and resurfaces it while they work.
- Researchers working across many sources, since the app links concepts into one continuous graph instead of separate notebooks.
- Founders who revisit the same decisions, because each session stores the reasons behind a choice so it can be recalled later.
- Obsidian and Logseq users who already collect material and want a tool that builds on it to extend their own thinking.
Tasks
- Long-form drafting, where Kompas AI brings back earlier notes at the moment they are relevant instead of leaving them buried.
- Working through a half-formed idea, since a session keeps asking questions based on what you have already decided.
- Organizing scattered reading, because highlights and documents get marked and connected rather than just saved.
- Building a personal knowledge base, as every session leaves traces that feed the graph over time.
Scenarios
- Returning to a project after weeks away, where the graph helps you pick up the thread instead of starting over.
- Writing an essay or article from your own prior work, since Kompas AI surfaces what you already wrote when it fits.
- Comparing an old decision with a new one, because stored reasoning makes past choices auditable.
Key features
Session-Based Thinking
As an AI thought companion, a session starts with a topic and works through it with the AI, pulling in your earlier notes, decisions, and reading to ask better questions. Each session leaves traces that stay in your library, so a single train of thought doesn't disappear when you close the window.
Connected Graph
Sessions, decisions, memories, and retrieved passages all connect into a graph rather than sitting in isolated files. Today's thought brushes against something from last month, which is how Kompas AI helps you build on what you already know instead of repeating it.
Writing That Stays Yours
Moving a session into a draft keeps your voice at the center. Kompas AI doesn't write for you. It writes with you by recalling what you already wrote, so the passages that surface are your own material rather than model output.
Bring Your Own AI
On Free and Pro Sync, you connect your own OpenAI or Anthropic API key, a Claude Code or Codex subscription, or local models through Ollama. Realtime voice and audio transcription need an OpenAI key. This keeps the model choice and the data path under your control.
Local-First Privacy
On the free desktop, your sessions, notes, and graph stay on your device, and Kompas AI doesn't collect telemetry by default. It keeps local AI notes by design: the only network calls are the ones you trigger with the providers you pick, and the app never trains on your content.
Cross-Device Sync and Managed AI
Pro Sync adds hosted sync so your graph follows you between desktops. Pro Full builds frontier AI in with no API keys and includes a monthly usage pool for long-context sessions, transcription, and knowledge extraction, with visible limits before any top-up.
Open Source Foundation
The desktop app is open source under the MIT license, so you can inspect how it handles your data. Cloud-only parts, such as billing and hosted models, live in a separate private repository.
Pros and cons
Pros
- Keeps your notes, sessions, and graph local on the free desktop, with no telemetry collected by default.
- Works with your own API keys, a Claude or Codex subscription, or local Ollama models, so you aren't locked to one provider.
- Turns sessions into a searchable graph, which makes past decisions and reading reusable instead of forgotten.
- Open source under MIT with JSON export on every tier, so leaving the tool is easy.
- Pro Full bundles frontier AI with clear usage limits and no surprise charges.
Cons
- Desktop only with no web app, so you can't use it on a phone, tablet, or in a browser.
- The free tier is single-device, so anyone with two computers needs a paid plan to sync.
- Pro Full routes requests through Kompas Cloud and third-party model providers, which matters if you want fully local processing.
- As a 0.x release, the app is still maturing, so some features and stability may shift over time.
Frequently asked questions
No. On the free desktop, your sessions, notes, and graph stay on your device, and the only network calls go to the LLM providers you choose. On Pro, your graph is hosted privately for sync, but Kompas AI still doesn't train on your content.
