Mind Graph Maker — capture what fills your head, as a pie chart

HOW IT WORKS

What Mind Graph Maker is

A tool for turning "what's taking up space in my head right now" into a pie chart of topics and percentages — and keeping it. It works like the "brain maker" charts that were popular on Japanese TV, except you write the slices yourself and can look back at them later. Each chart saves as an image with your name, date, and time, ready for X, LINE, Threads, or Instagram, and a one-line journal entry is stored with it. A week or a year later you can compare circles and see what you were thinking about.

How to use it (three minutes)

1. Write the slices. Tap a label on the chart to type directly. Up to eight slices. Drag the white boundary dots to change a share; the total is kept at 100% automatically. Sliders work too.
2. Add one line. The "why is my head like this?" box is for today's mood or event. It is optional.
3. Save and share. "Save journal and chart" adds it to your history; "Share image" produces a PNG with name and date. On supported devices it goes straight to the share sheet; otherwise save the image and attach it to a post.

Two ways to draft a chart from text

1. Paste and tally (on your device)

Paste your posts, an AI conversation, or notes, and the tool counts topic keywords — food, work, people, plans, and so on — entirely inside your browser to draft slices and shares. Nothing is sent to a server, and the tool never connects to your X or AI accounts. If no topics are found, it says so; switch to manual entry.

2. Ask your usual AI

"Copy the prompt" gives you an instruction to paste into whichever AI assistant you already use. It asks the assistant to summarise your own messages into three to eight topics as JSON, with no diagnosis. Paste the JSON back and the chart is filled in.

Where your data lives

• History and journal entries are stored in this browser (localStorage). Nothing goes to our server, and there is no sync between devices.
• Clearing browser data clears the history. Export a JSON backup first and import it on another device or browser (up to 5 MB).
• Images are saved to your device only. This site never posts to social media on your behalf.

FAQ

Is this a psychological test?

No. It is a form of journal — you write the slices. The automatic tally only counts keyword frequency and does not assess anyone's mental state.

When is it fun to use?

At the end of a week, on a birthday, before and after an exam or a presentation, on the way home from a trip — any moment you want to capture. Swapping charts with a friend shows at a glance how differently two heads are occupied.

Does it work on a phone?

Yes. It runs in the browser with no install or sign-up. If dragging the boundary dots is fiddly, use the sliders underneath.

Who owns the image?

You do. It carries a small "#MindGraphMaker · toriumis.com" mark, and there are no restrictions on personal use or posting.
