## 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

## Wonderfall

Wonderfall describes itself as the antidote to tab anxiety. Rather than letting dozens of open tabs become a to-do list you never finish, it gives you a single companion for capturing what matters. At its core is one-click smart bookmarking: pages are saved, tagged and categorised automatically, so you never lose an important link again.

Beyond bookmarks, Wonderfall adds distraction-free note-taking that links each note to the page it came from, and a Sessions feature that groups related bookmarks and notes together with a timeline view. That combination lets you visualise a browsing journey, retrace your steps and continue exactly where you left off — useful for research, study or project work.

Wonderfall is a lightweight Chrome extension (roughly 300 KB) published under wonderfall.xyz and available in the Chrome Web Store. It lists features such as local encrypted storage with optional cloud sync and sharing of curated sessions with colleagues. Note that the extension's original marketing domain is no longer under the developer's control, so the Chrome Web Store listing remains the most reliable source of current information.

**Pricing & Plans:** Wonderfall is freemium: the extension can be installed and used for free, with optional in-app purchases for additional features. Because the developer's own site is no longer available, the Chrome Web Store listing is the best place to confirm current pricing.

- **Smart bookmarking:** Save pages in one click with AI-generated tags and automatic categories, so links stay findable instead of buried in tabs.
- **Linked note-taking:** Capture ideas without leaving the page, with each note automatically linked back to its source for easy reference.
- **Sessions and timeline:** Group related bookmarks and notes into Sessions and revisit them in a timeline view to retrace your research.
- **AI tagging and organisation:** AI tags and automatic categorisation reduce manual filing, so you spend less time organising and more time reading.
- **Privacy and sharing:** Keep data encrypted and local, sync across devices optionally, and share curated Sessions with teammates or friends.

**Strengths:** Combines bookmarks, notes and tab sessions in one tool; AI tagging and auto-categorisation cut down manual filing; Sessions with a timeline view make research easy to retrace; Lightweight extension with local encrypted storage and optional sync

**Limitations:** The developer's own website domain is no longer usable, so documentation and support may be harder to find; Very small user base and review count, which limits community feedback; Last extension update was in 2024, so feature development may have slowed; Some advanced features require in-app purchases, and cloud sync needs opting in
