Too much on your mind, and no idea where to start? AI chats, posts you saw, books you read, things people told you. There is more to think about every day. ThinkSpace is a thinking notebook: put your thoughts on cards, then arrange and connect them as you think. As you move cards around and put ideas into your own words, your understanding deepens. ■ How it works Start with a single card: whatever is on your mind. 1. Collect: AI chats, web pages, photos, passing thoughts, via the Inbox or by pasting. 2. Write it down: turn them, and what is in your head, into handwritten or text cards. 3. Arrange and see the big picture: move, group, and connect cards. Step back, and unexpected connections, next questions, and next actions appear. 4. Explain: say what your cards or map mean, out loud, in your own words. Read the transcript back to check what you really understand. ■ Great for - Clearing your head when AI chats pile up - Making sense of books and videos, and turning them into questions and actions - Connecting ideas from research papers and textbooks so you can explain them in your own words - Creating nursing concept maps and connecting conditions, symptoms, and care - Bringing a story's world, characters, timeline, and ideas into one structure - Journaling: writing out tangled feelings and worries - Designing your career in the AI era, a social media strategy, or a product - Connecting visions and goals to concrete actions and reviews - Working through 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 about a card and add the answers to your map. Break answers into ideas, connect them, and make sense of them in your own words; looking over the map sparks new questions to dig into. Your AI inputs are never used for training. ■ Key features - Infinite canvas: place cards anywhere, half-formed thoughts included. - Handwriting and text: Apple Pencil supported. Jot down ideas on cards and move them around with your finger. - Mind maps, flowcharts, groups, and connections: radial thinking, steps, cause and effect. - Send from AI chats: send a conversation from Claude or the share sheet to the ThinkSpace Inbox, then drag it in as a card. - Explain out loud: describe a card or map in your own words; it is transcribed and saved. You notice where your understanding is thin, and can read it back later. - Ask AI: ask about a card and add the answer as a new card. - Extract key-point cards from long notes and web pages. - AI brainstorming: branch a topic card into angles and questions. - Paste into cards: copied text, photos, or URLs become cards. - Add web pages, images, and screenshots to your canvas. - Search and reuse cards across maps. - Link canvases: big themes and subtopics in layers. - Export to image, PDF, and text. - Local-first: saved on your device, works offline. - Sync across devices (Pro): iPhone, iPad, and Mac. Turn scattered information and AI answers into understanding you can explain and act on. ■ Pro access - Unlimited canvases - Unlimited cards and groups - Expanded AI usage limit - Full feature access ——— Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period.

Verdict

The call

The clearest difference is ads: ThinkSpace at none against MindFlow's shown. ThinkSpace also leads on update cadence (every 6 weeks vs every 17 months) and ratings volume (276 vs 33). MindFlow's advantage is review sentiment (70% vs 54%) and iOS requirement (12.0 vs 15.6). On price, rating, in-app purchases and monetization model there is nothing between them.
