## 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

## Dia Browser

Dia rethinks the browser as a workspace assistant rather than a window full of tabs. Instead of bolting a chatbot onto a page, it gives the assistant awareness of your broader context: open tabs, linked Google Workspace or Microsoft Teams content, plus connected tools such as Slack, Notion and GitHub. Practical examples include a Morning Brief that assembles your calendar, inbox and key links before the day starts, a 'Live Work' tab row that surfaces the places work is actually happening, and a Better Meetings mode that opens the right meeting page, agenda, notes and related docs with a countdown so you join on time.

The assistant is designed to produce artifacts rather than just answers. You can ask Dia to turn scattered context into a shareable report, or request a deck and receive real slides with headings, layout and flow that need no redesign. Splits let you place a meeting on one side and a document on the other, and Dia remembers layouts for recurring meetings or focus blocks. Tabs can be grouped automatically with meaningful names such as 'Design Review' or 'Q2 Planning' instead of an unreadable strip. Profiles keep work, freelance and personal browsing — and their AI context — separate, switchable with a swipe.

Privacy is treated as a product feature. Controls are explicit and user-facing: tracker blocking, ad blocking, memory on/off, personalised new chats, and sharing of content data, all toggleable. The company states that data is never sold or used to build ad profiles, that Sync is end-to-end encrypted, and that a separate 'Dia for Work' tier adds SSO and admin tooling for teams. Dia is available as a free download for macOS and Windows, with a release notes and changelog page tracking frequent updates.

**Pricing & Plans:** Free to download and use on macOS and Windows. The company also promotes a 'Dia for Work' offering aimed at teams, which adds enterprise controls such as SSO and admin tools; check the official site for current enterprise terms.

- **Morning Brief:** Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.
- **Context-aware answers across tabs and apps:** Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.
- **Decks and reports from scattered context:** Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.
- **Live Work tab bar:** Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.
- **Profiles and encryption controls:** Separate work, freelance and personal browsing contexts, with tracker/ad blocking toggles and end-to-end encrypted sync.

**Strengths:** AI is built into the browser's core workflow rather than added as a sidebar; Context spans tabs, email, calendars and connected work tools for genuinely useful answers; Outputs are artifacts — reports and slide decks — not just chat responses; Explicit, user-facing privacy toggles plus end-to-end encrypted sync

**Limitations:** Only available on macOS and Windows, with no Linux or mobile release at present; Deep integrations work best inside Google Workspace or Microsoft 365 environments; Heavy reliance on connected data may not suit strict compliance setups without the work tier
