## Capacities

Capacities starts from a simple observation: the way most tools organize information — nested folders and files — does not match how people actually think. The app replaces that hierarchy with objects. A person is an object, a book is an object, a project is an object, and each one has its own structure and properties. Because everything can link to anything, your notes build a network rather than a filing cabinet.

Writing starts in a daily note that acts as an inbox, so there is no pressure to file things immediately. From there you create the object types you actually need and link them as you go. Backlinks show every connection to a note at a glance, and a Related Content feature surfaces places where you wrote about something but never made the link explicit — connections you had already made, found automatically.

Capacities runs on web, macOS, Windows, Linux, iOS and Android, and works offline with synchronisation across devices. The core note-taking product is free, with paid Pro and Believer tiers that add AI features, whiteboards, task management, smart queries, calendar integration, media analysis and version history. The team is small, fully remote and independently funded.

**Pricing & Plans:** Freemium. Capacities Basic is free forever with unlimited spaces, objects and blocks. Capacities Pro is $9.99/month and adds AI features, whiteboards, tasks, smart queries and calendar integration; Capacities Believer starts at $12.49/month and adds beta access to new features. A Plus AI add-on increases the monthly AI budget. Yearly billing is discounted.

- **Everything is an object:** Model people, books, projects and meetings as typed objects with their own properties, instead of forcing them into folders.
- **Backlinks and related content:** See every link to a note at a glance, and let Capacities surface unlinked mentions where you already wrote about the same thing.
- **Daily notes as an inbox:** Capture thoughts without deciding where they belong first, then link and refine them later.
- **AI assistant and media analysis:** On paid plans, an AI assistant works alongside your notes, and image, PDF and weblink analysis turns outside material into usable content.
- **Works across all your devices:** Native apps for web, Mac, Windows, Linux, iOS and Android with synchronisation and offline support.

**Strengths:** Object-based model removes the friction of constant filing decisions; Related Content surfaces connections you never explicitly linked; Free tier is genuinely usable, with full import and export; Native apps on all major platforms, including Linux

**Limitations:** Some of the most useful features — AI, tasks, calendar — sit behind the Pro subscription; Not a Markdown-first, plugin-extensible tool, which limits fine-grained customization; AI usage is budget-based, so heavy AI users need the Plus add-on

## mindlib

mindlib is a personal knowledge management tool built around a graph rather than a flat pile of notes. You store information — text, ideas, references, clipped web content — and then connect entries in parent-child relations so a real knowledge network grows over time. Mind maps give that network a visual surface, which makes it easier to see how a project, a topic or a research thread fits together.

The product leans on AI in two ways: an assistant that can chat about your library, and mind-mapping support that helps structure what you have captured. A universal search bar sits at the centre of the workflow, so you can both file and retrieve information from the same place, and a share target lets you capture ideas from other apps.

Deployment is deliberately cross-platform. There is a web application at app.mindlib.de and dedicated Android and iOS apps, with sign-in syncing your library between them. The free tier covers small libraries of up to about 100 items, while a monthly or yearly subscription unlocks unlimited storage; importantly, data you have already created remains available and synchronised even if a subscription lapses.

**Pricing & Plans:** Freemium. The free version supports up to roughly 100 pieces of information. A monthly or yearly subscription unlocks unlimited knowledge storage, and existing data stays available and synchronised across devices after a subscription ends. Exact prices vary by plan and are shown in-app or on the store listings.

- **Graph-based knowledge network:** Save notes, ideas and web clips into a single library, then connect them in parent-child relations to grow a structured knowledge network.
- **AI mind mapping:** Turn collected entries into mind maps so you can see how topics, projects and references relate at a glance.
- **AI assistant and chat:** Ask the built-in AI assistant questions about your own library, or capture and find information conversationally.
- **Fast capture and universal search:** Use the all-in-one search bar and share target to capture ideas the moment they appear, without hunting for the right folder.
- **Web and mobile apps:** Work in the web app at app.mindlib.de or the Android and iOS apps, with your library synchronised across every device.

**Strengths:** Graph and mind-map structure that suits research and long-term projects; AI assistant and chat over your own private library; Cross-platform: web app plus Android and iOS apps with sync; Data remains accessible even after a subscription ends

**Limitations:** The marketing root domain currently returns a server error, so the web app link is the reliable entry point; The free tier caps stored items at around 100, which power users will hit quickly; Heavier than a plain notes app: mind maps and parent-child links take deliberate effort; No public API or rich third-party integration ecosystem advertised
