## What is ThinkSpace?

Information piles up. AI gives you answers. Yet the more you collect, the more scattered it all becomes — and it's hard to see what really matters and what to do next.
ThinkSpace is a thinking tool that lets you place scattered notes, AI answers, web pages, images, and handwriting on one infinite canvas — and turn vague, complex topics into a map you can understand, explain, and act on.
Put down half-formed thoughts before they become sentences. Move cards with your fingers, write with Apple Pencil, group and connect — and find the structure of the problem, key relationships, cause hypotheses, and the next questions to think about, with your own hands.
In ThinkSpace, a map you grow for understanding, judgment, and action is called a design map. It is not a static diagram you draw once. It keeps evolving as you add new information, AI conversations, and results from what you tried — a living model of your own understanding.

■ Great for topics like
- Integrating papers and books into an understanding you can explain in your own words
- Visualizing nursing pathophysiology diagrams and how what you learn connects
- Bringing a story's world, characters, timeline, and ideas into one structure
- Writing out tangled feelings and worries to sort out your inner thoughts
- Designing your career in the AI era, social media strategy, or product concepts
- Connecting visions and goals to concrete actions and reviews
- Working through complex problems at work: causes, solutions, validation, results

■ Start from a purpose-built map
No need to stare at a blank canvas wondering where to begin.
- Concept map
- Problem-solving map
- Pathophysiology map
- Career map for the AI era
- Worldbuilding map
- Social media strategy map
- Habit-building map
- Product design map
- Vision map
and more — start from a foundation that fits your topic.

■ Turn AI chats into a growing map
Ask AI from a card and add the answers to your map. Instead of just reading responses, break them down, relate them, and rebuild them as your own understanding. Looking over the map sparks new questions — dig into them with AI again. Your AI inputs are never used for training.

■ Key features
- Infinite canvas: place cards anywhere and work with unorganized thoughts as they are.
- Handwriting and text: Apple Pencil supported. Write like sticky notes and move them as you think.
- Mind maps, flows, groups, relation lines: express radial thinking, procedures, cause and effect.
- Ask AI and break answers into cards: turn answers into understanding you can explain.
- Extract key-point cards from text: turn long notes and web pages into material for thinking.
- AI brainstorming: generate a skeleton that widens your view. You fill in evidence and conclusions.
- Capture web pages, images, screenshots: place research inside your own topic.
- Search and reuse cards: find past fragments and recombine them in other maps.
- Link canvases: connect big themes and subtopics into layers of thought.
- Export to image, PDF, and text: output maps for reports, submissions, and sharing.
- Local-first: data is saved on your device first. Edit offline, export anytime.
- Sync across devices (Pro): grow the same maps on iPhone, iPad, and Mac.

Turn AI answers into understanding you can explain. Turn scattered information into a map that leads to your next decision and action.
Grow your own way of thinking with ThinkSpace.

### 1/5 — Japan Rule

*2026-08-19, version 7.1.0*

I can’t sign up to this app due to its anti-US rhetoric in its terms of use and policies. It simply states that where theres nuance, Japan rule overrides it, that doesn’t work in the US since if you sell to the country, you are required to follow their rules of engagement. And I won’t accept “we really didn’t mean that… You misunderstood” which is the usual go-to responses. They are also called “Thinkspace” yet have put full stop on any kind of content that might hurt someone’s feelings that might be in some of the research. I have a hard time with this since my research is often challenging. I wouldn’t want my documents deleted or taken down just bc someone from Japan reads it out of context. I had high hopes.

### 1/5 — 오류 심해서 한동안 안썻는데 자동결제 되네요 환불해주세요

*2025-12-10, version 6.4.8*

환불해주세요

### 3/5 — またお金

*2025-11-09, version 6.4.8*

すごく使いやすかったのに一瞬でカード数グループ数制限…。あとは金払え…。これじゃ意味ない。学生には無理です。

### 3/5 — Great App

*2025-11-06, version 3.4.6*

Great app, I wish things didn't move on their own though. Otherwise I'm very happy

### 1/5 — Shady terms of service

*2025-08-08, version 6.4.8*

‘’By using our products, you give the Provider's permission to do certain things with your data’’ I will not be using this app for this alone, but the list goes on! I’ll stick with qrayon’s apps for better privacy.

### 1/5 — I wrote an email but got no response. Rating is just to catch your attention. I'll update it.

*2025-07-27, version 6.4.7*

Hello!

I am using this app and making a tree diagram. The limited version gives me I guess 70 elements to add. Before I go for purchase, it’ll be helpful for me to know the limits of the full upgraded version in terms of how many depth levels can I go, how many elements can I have in each depth, just like the limits on rows and columns of a two dimensional matrix having limits m and n. Also, how many total elements I can fit in the tree diagram (m*n). This info will be really helpful for me in taking the decision.

Also, I want to ask if there's a one time lifetime purchase option to skip monthly or annual subscriptions, Id like to go for that in case my requirements are met by the app.

Thanks,
Naveen K

### 2/5 — Awkward to find the things you want to put on canvas

*2025-06-12, version 3.4.6*

Could not find basic shapes, the over UI experience was difficult for me

### 1/5 — bad design

*2024-08-28, version 3.4.6*

laggy and confusing

### 3/5 — 有料版へのアップグレードができない。

*2024-07-10, version 6.4.7*

とても素晴らしいアプリだと思います。
仕事上での使用はもちろん
資格勉強のためにマインドマップ作成にも役に立つなと思いキャンバスやカードを増やすためにアップグレードしたいが案内とプライバシーポリシーや利用規約が表示されるだけでアップグレードの仕方がわからない。

### 2/5 — Confused, but holding hope.

*2024-04-17, version 3.4.6*

ThinkSpace is simply non-responsive after installation. I've checked that my system meets requirements. As it does, I'm lost to find a reason.

I really want to try this out. I am fully prepared to think it's great... but it needs to function! I've written directly to the developer with system details. 

I hope I'll get a response that gets me going. I have 5-star hopes judging by feature descriptions and screen shots.
