## 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

## Gems

Gems approaches knowledge management from a different angle than traditional note apps: instead of asking you to file, tag, and cross-link everything by hand, it invites you to just ask. Connect your tools, then pose a question in your own words — or clip a piece of text to give context — and Gems returns a synthesized, written-out answer it calls a Gem.

Each Gem is structured prose rather than a raw list of hits, and every answer keeps its sources attached. That combination matters: it means you get an answer you can use immediately while still being able to trace it back and verify it, which is the key requirement for knowledge work where accuracy is non-negotiable. The system searches across everything you and your team have stored, so answers reflect your actual context rather than generic web results.

The product also emphasizes low maintenance. Rather than another folder hierarchy to curate, Gems aims to be a knowledge repository that nearly fills itself, shows how your knowledge is connected, and lets you paste a Gem into whatever app you are already using. With desktop and mobile apps and a stated install base in the tens of thousands, it targets professionals and teams who want their accumulated knowledge to become instantly queryable.

**Pricing & Plans:** Gems offers a free way to get started, with a dedicated pricing page for additional tiers. Because the product is presented as beta and exact numbers are not spelled out on the homepage, check gems.so for current plan details.

- **One Shortcut to All Your Knowledge:** Summon Gems with a shortcut and ask anything in your own words instead of digging through folders and apps.
- **Structured Written Answers:** Gems returns structured, written-out answers rather than a list of links, so you can act on them immediately.
- **Sources With Every Answer:** Every answer includes its sources, so you can go back and prove where a conclusion came from at any time.
- **Zero-Upkeep Organization:** Connect your existing tools in seconds and let Gems index your knowledge without manual filing or tagging.
- **Share and Paste Anywhere:** Press a key to paste a Gem into any app, or post it into shared spaces so teammates see the same answer.

**Strengths:** Answers are written out and structured, not just a list of links; Sources accompany each answer, supporting verification; Minimal setup and zero manual organization required; One-click pasting means answers land inside your existing tools

**Limitations:** The site presents itself as beta, so features may still change; Value depends on connecting and indexing your existing tools and notes; Desktop-first emphasis in some messaging may not suit mobile-only users; No granular public pricing detail is shown on the homepage
