Most note-taking apps are great at storing text but terrible at showing how ideas connect. And most mind map tools are powerful but disconnected from the rest of your workflow. I wanted something that did both — in one place, without the clutter.
I built this because I kept bouncing between a mind map app for brainstorming and a separate notes app for the actual content. Every session started with the same friction: open two apps, try to keep them in sync, lose the thread. I wanted a single tool where a mind map node could hold real notes — text, images, links — not just a label.
What It Does
- Interactive mind maps — Add and move nodes freely to map out your thinking. Branches grow as your ideas do, and nothing is locked in place.
- Rich notes attached to nodes — Each node can carry a full note with text, URLs, images, and tags. Your mind map becomes a living document, not just a diagram.
- Folder organization with nesting — Standalone notes live in folders you can nest however you like, so even a large collection stays navigable.
- Share from any app — Send a link or image from your browser, a messaging app, or social media directly into a new note. No copying and pasting between apps.
- Sync across all your devices — Sign in on any device and your notes and mind maps are right there. Nothing lives only on one phone.
The app is called 시우노트 in Korean — Siu Note — and while it started as a tool I built for my own use, the core problem it solves is pretty universal. If you sketch mind maps during meetings or lectures, if your bookmarks and saved links are piling up with no real system, or if inspiration tends to arrive faster than you can organize it, this app was designed with you in mind.
The free tier includes 1 GB of storage, which is a comfortable starting point for most people. If you work with a lot of images or have years of notes, optional Plus and Pro subscriptions bump that up to 20 GB and 100 GB respectively, on either a monthly or annual basis. Subscribers also see no ads. Pricing is shown in your local currency at checkout.
On the privacy side: all data is encrypted at rest, you can sign in with Google, Apple, or email, and you can permanently delete your account and everything in it at any time. No lock-in, no dark patterns.
This is version 1.0.1 — early days, but stable enough that I use it as my daily driver. If you have been looking for a cleaner way to connect your rough ideas to the notes that flesh them out, give it a try on the App Store and let me know what you think.
