[Hakushi Notes 2 | Hakushi Notes] AI + MCP: What Changed in My Note-Taking App (All in AI)

Continuing from Last Time

June 19, 2026. I released the first version of Hakushi Notes. At the time, we set our sights on going All in AI, building a note-taking app that combined immersive writing, AI, sharing, and printing in one place. That version was built from the perspective of my senior year of high school, based on what I genuinely needed. Today, we're releasing Hakushi Notes 0.2. In this version, we've taken in feedback from users across the web alongside our own real-world needs. While improving the web app's usability, we focused heavily on the AI experience. Through MCP, we've moved the entry point for capturing notes from opening a webpage to right in front of you. You can even long-press your phone's power button and, from the most convenient AI entry point on your device, have your fleeting thoughts written down on a blank page. (For now, few mobile AI assistants support MCP; the best domestic option remains the new Super Xiaoai in HyperOS 4. On desktop, Tencent WorkBuddy, Doubao Work, MiMo Desktop, and other AI platforms are supported.)

A Real Question

Before building 0.2, I kept thinking about one question: what problem is a note-taking app actually solving?

On the surface, it solves "recording." But if you think about it, recording itself was never the hard part. The hard part is the distance between "I have a thought" and "I write it down."

You're walking down the street and an idea flashes through your mind. Pull out your phone, unlock it, find the app, open it, create a new note, start typing—six steps. Inspiration doesn't have the patience to wait for you to finish those six steps. Most of the time, it's gone before you even realize what you lost.

So we did one thing: we shrank that distance to zero.

The First Entry Point—MCP

Hakushi Notes now has two entry points. The first is through MCP, letting AI take notes for you directly.

You're on the road and something suddenly comes to mind. Long-press the power button and say to your AI: "Note this down in Hakushi Notes for me: I think everyone actually lives inside their own version of reality." (This is whatever you happen to be thinking at that moment.)

The AI calls Hakushi Notes through the MCP protocol, organizes your words into text, and saves it to your note list. You didn't open any app, didn't touch the screen, didn't switch interfaces. You just said one sentence, and it's already sitting in Hakushi Notes.

MCP is the core of this. It builds a bridge between the AI and Hakushi Notes—the AI doesn't need you to manually open the app; it can create and save notes on its own. You're always facing just one window: the AI. But your words have already landed safely.

This entry point solves one problem: when inspiration strikes, catch it first. Whether it's mature or not, whether it's complete or not, just get it down. Everything else can wait.

Of course, what I described above is just one possible scenario. What we've given the large model is a complete toolchain—you can use MCP to query, create, edit notes, generate share links, and delete them.

The Second Entry Point—You

"Everything else" happens in the second entry point.

You get home, open Hakushi Notes, and see that quick note: "Everyone actually lives inside their own version of reality."

You look at that sentence and start wondering—what does "their own version" mean? Does everyone see a different world, or do they remember the same events differently? So you start writing. You write, delete, write again. Finally you write: "Maybe everyone is telling themselves a story, and then mistaking that story for reality."

Hakushi Notes has a clean interface. The AI assistant sits quietly in the sidebar—click it when you need it, and when you don't, it's as if it isn't there. The design intent of this entry point is simple: let you sit down and spend some quiet time with your own thoughts. (This was already in the previous version.)

Two entry points, two rhythms. The first is fast—it helps you catch inspiration. The second is slow—it lets you turn that inspiration into something truly yours. From 0 to 0.5 is the speed of AI; from 0.5 to 1 is the depth of you.

What Else Is New in 0.2

Better usability. Taking in user feedback, we realized that stripping everything away doesn't spark inspiration. Removing the toolbar only raises the learning curve and works against people's intuition. Our approach was to add a standard editing toolbar while keeping the design and style highly consistent, so it doesn't disrupt your writing. We also added synchronized scrolling between the preview and editor panes, making it easier to find your place.

Annotations. You can now annotate your notes in the editor at any time instead of modifying them directly. Before making changes, you can keep your original thoughts intact and update your new ideas in the annotations.

Improved sharing. Building on the previous point, sharing now integrates with annotations. You can choose whether the person you share with can see your annotations, and whether they can add new ones. Viewing requires no login. After registering and logging in, the person you shared with can annotate your original note, with their name always attached.

Gradual attachment uploads. Markdown is a rich-text format—if it loses the ability to embed images, audio, and links, it loses its soul. To make inserting images and other attachments easier, we're giving every Hakushi Notes user 80MB of completely free storage. By following the creator, it automatically expands to 592MB (80 + 512). If the response is good, we'll offer richer paid plans and increase the free tier. For now, I think 592MB is enough for a note-taking app.

Why It's Called "Blank Paper"

Blank paper doesn't mean "nothing there." On the contrary, blank paper means: completely free of distraction, with no cost and no barrier to entry. This is also how we understand All in AI—AI should be everywhere, quietly lowering the barrier to capturing your thoughts. But the act of recording itself, those fragments, that messiness, those words only you can understand—that should be yours. AI helps you catch inspiration faster, but the road from inspiration to idea is one no one can walk for you.

Finally

In my senior year of high school, I often zoned out during evening study sessions and scribbled random thoughts in the corners of scrap paper. Those scraps are long gone, and most of those thoughts are forgotten. But I remember the feeling—when I was writing, I felt like I was truly alive.

That's the feeling Hakushi Notes wants to protect.

A blank page is always waiting for you. Not because it's empty, but because it believes you'll eventually write something down.
