## 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

## Flexnote

Flexnote organizes notes as cards placed freely on an infinite canvas rather than in a linear document. You can zoom, drag, and rearrange them, or view the same board as a mind map, while typing @ creates bidirectional links that turn loose cards into a connected knowledge network. A tag-based database view lets the same cards double as a task list, book library, or web-clipper archive.

Annotation is a core workflow. PDFs and videos can be dropped onto the canvas to highlight, comment, and generate linked knowledge cards; video annotations support timestamped notes from major platforms, so a quote in a lecture links straight back to the moment it came from. Sharing is one click — any canvas becomes an interactive webpage with optional password protection and no account needed for viewers.

Unlike cloud-first tools, Flexnote stores files on your device by default and is fully usable offline. For multi-device work you connect your own storage via WebDAV, Amazon S3, OneDrive, or Baidu Netdisk, and credentials stay under your control. Flexnote AI runs semantic search and knowledge-base Q&A over your notes; chat uses your own model API key, and index points are bundled with Pro plans. A custom rendering engine keeps panning and editing smooth even at 10,000+ nodes.

**Pricing & Plans:** Flexnote has a free plan with 3 whiteboards, 100 cards, core canvas features, and local storage. Pro and Lifetime plans unlock unlimited whiteboards, Flexnote AI smart-index points, and optional cloud sync; during promotional periods a Lifetime license has been offered at a discounted price. See the pricing page for current plans and point quotas.

- **Infinite canvas with mind maps:** Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes.
- **PDF and video annotation:** Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards.
- **Knowledge-base AI:** Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key.
- **Local-first with your own cloud:** Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours.
- **Publish to the web:** Turn any canvas into an interactive webpage with a single link, with optional password protection and no account required for viewers.

**Strengths:** Local-first storage means notes stay on your device and work offline; Combines infinite canvas, mind maps, and databases instead of splitting tools; PDF and video annotation with automatic reference cards is rare in note apps; Sync uses your own WebDAV, S3, or OneDrive accounts, so you keep control of data

**Limitations:** The full web app is not finished; online access is view-only so far; Flexnote AI smart-index points are billed separately from AI chat usage; Advanced publishing and AI features sit behind the Pro or Lifetime tiers
