## 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

## Ideaflow

Ideaflow is a deliberately stripped-down notebook. Instead of folders, databases and formatting toolbars, it gives you an almost instant writing surface where you type a thought and move on. Everything you capture lands in a single, chronological, searchable stack, so there is no filing decision to make in the moment and no place for an idea to get lost.

The product's angle is speed and recall rather than heavy structuring. Notes sync across the web app and mobile browsers so an idea captured on a phone is waiting on the desktop, and search is designed to surface a half-remembered fragment rather than requiring you to recall exact wording or location. Ideaflow also exposes a connector that lets Claude and ChatGPT read from your notebook, so the notes you accumulate can become context for AI-assisted thinking.

Ideaflow is aimed at people who generate more ideas than they can organize — founders, writers, researchers and product people who want a frictionless inbox for thinking. It is available on Chrome and Safari on both desktop and iOS, with a free tier to start and paid plans for heavier use.

**Pricing & Plans:** Ideaflow offers a free tier to get started, with paid subscription plans for additional capacity and features. Check the official site for current pricing.

- **Instant capture:** A minimalist writing surface that opens and records a thought with almost no friction, so ideas are saved before they slip away.
- **Searchable note stack:** Every note flows into one chronological, searchable stack, removing folders and filing decisions while keeping everything findable.
- **Cross-device sync:** Notes captured in the Chrome or Safari web app and on iOS are synced, so the same stack is available wherever you write.
- **Claude and ChatGPT connector:** A connector lets supported AI assistants read from your notebook, turning accumulated notes into usable context for AI conversations.
- **AI-assisted recall:** Search is tuned for recovering loosely remembered fragments rather than requiring exact keywords or a remembered location.

**Strengths:** Extremely low-friction capture with no folder or tag decisions up front; Notes accumulate in one chronological, easily searchable stack; Connector lets Claude and ChatGPT draw on your own notebook; Works in Chrome and Safari on both desktop and iOS

**Limitations:** Minimal structure is a poor fit if you rely on hierarchical folders or databases; Collaboration and team workflows are not a focus; Some advanced capability sits behind paid plans
