## 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

## GPTKeeper

GPTKeeper exists to solve one very practical problem: ChatGPT conversations are easy to lose, hard to reference later, and awkward to send to other people. The extension attaches itself to your ChatGPT session and adds straightforward controls for capturing a whole thread, exporting it as a PDF document, and generating a link you can hand to a colleague, classmate or friend.

Because it is distributed through the Chrome Web Store, installation is a one-click affair and no separate account is required. The extension is deliberately narrow in scope: it does not try to become a chat client, a prompt library or a knowledge base. Instead it behaves like a clipboard for your AI conversations, which makes it quick to learn and light on system resources.

The listing notes a modest user base and the interface text is mainly in Japanese, so it is best suited to Japanese-speaking users or anyone comfortable working with a simple, icon-driven toolbar. It handles website content in order to read the conversation you are currently viewing.

**Pricing & Plans:** GPTKeeper is free to install from the Chrome Web Store. No paid tier or subscription is listed.

- **One-click conversation saving:** Capture an entire ChatGPT thread without copying and pasting message by message.
- **PDF export:** Download the saved conversation as a PDF file that can be archived, printed or attached to an email.
- **Link sharing:** Generate a shareable link for a conversation so others can read it without a screen recording or screenshot.
- **Social network sharing:** Publish a conversation directly to networks such as Facebook or Twitter, or embed it on a website.
- **No account needed:** Runs as a browser extension with no sign-up, keeping the workflow to a couple of clicks.

**Strengths:** Very simple, focused workflow that takes only a few clicks; PDF export gives you a durable offline copy of a conversation; Free to install with no account or sign-up required; Small download size, so it barely affects browser performance

**Limitations:** Interface text is mainly in Japanese, which limits accessibility for other audiences; Last updated in 2023, so it may lag behind newer ChatGPT interface changes; Only useful to people already using ChatGPT in a Chrome-based browser
