Capacities offers links between these objects, so hidden connections appear like a mind map.
This bottom-up approach lets organization emerge as you write, much like an artist’s studio.

1. Note Taking Approach
容量： You create notes as objects. A book, a person, or a 会议 each becomes its own object type. This lets you organize multiple notes into structured content. The app supports markdown notes, so writing feels fast and clean.
内存人工智能： You just write and drop ideas in. The AI notes app skips folders and uses AI to sort all your notes. This removes manual organization, which helps if you hate filing things by hand.
2. AI Assistant
容量： The AI assistant lives on the Pro plan. It can draft new content, answer questions about your notes, and brainstorm ideas. The AI features feel like an add-on to a strong manual system.
内存人工智能： AI sits at the center here. Mem’s AI features power a smart AI writer and a knowledge-aware assistant. The AI helps with content generation and turns raw notes into active data.
3. Linking and Hidden Connections
容量： Contextual backlinking is the core of the app. Every link builds a mind map of your thinking. You see hidden connections between objects, which sparks new ideas across your knowledge base.
内存人工智能： Links happen through AI, not by hand. Mem AI shows related notes and similar notes as you write. It builds an AI knowledge base that connects different pieces of information for you.
4. Powerful Search
容量： The powerful search tool helps you find notes by object, tag, or page. The powerful search find feature scans your whole knowledge base fast. It works well once your tags are set up.
内存人工智能： Smart search is the headline feature. You ask plain English questions and Mem AI finds notes quickly. Reports cite a 60% drop in search time, which surfaces relevant information without digging.
⚠️ 警告： Smart search shines with lots of data. With only a few notes, both apps feel similar at search.
5. Capture and Integrations
容量： Quick capture and a share sheet save content from web pages without breaking focus. You can drop links and ideas in seconds. Integrations are lighter than tools built for project management.
内存人工智能： Useful integrations pull in Google Calendar, Slack, and Google Docs. Your messages and documents flow into one place. This makes Mem AI strong for capturing 会议记录 from other tools.
6. Templates and Structure
容量： Templating keeps your structured content consistent. You build templates for object types like books or projects. This rewards a bit of upfront setup with a tidy, repeatable system.
内存人工智能： You can create templates for repeated note types too. They save time and keep notes consistent. But structure is looser here, since the AI handles most of the organizing.
7. Organization and Object Types
容量： Custom object types let you shape the app around your life. Daily notes and a calendar keep a clean log. This bottom-up method helps creative thinking grow from the ground up.
内存人工智能： The AI organizer does the sorting for you. It tags and groups notes in the background. This suits people who want a second brain without the manual setup work.
8. Writing and Summaries
容量： Block linking lets you connect ideas inside long pages. You write in markdown and reuse blocks across multiple notes. It is built for thinkers who want to create amazing things from their own structure.
内存人工智能： Summarization condenses long notes in one click. The assistant can generate new content and pull out key details. It acts like a personal assistant for your writing.
9. 定价与成本

Capacities is a studio for your mind, built on objects and links.
Mem AI is a powerful assistant that does the organizing for you.
