## 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

## PlutoAI – AI Bookmarks and Tabs Manager

PlutoAI is described by its publisher as a personalized AI bookmark manager. Instead of letting articles pile up in a bookmark bar, it automatically sorts saved pages into topics and tags, produces AI-powered summaries and TLDRs so you can absorb the key points in seconds, and recommends further reading that aligns with what you already save.

The extension also reaches beyond bookmarks. It manages open tabs and browser sessions, letting you save a session and resume it later with a single click. Smart alerts nudge you to finish articles or videos you started but never completed, and a full-text search with tag and filter controls makes it possible to find a specific page even if you only remember a fragment of its content.

The extension is published by TWEENY TECHNOLOGIES PRIVATE LIMITED and distributed through the Chrome Web Store. It is aimed at people who save a lot of content and then struggle to find, read, or organize it. Note that the product is a third-party extension and is not affiliated with Google or the Chrome team.

**Pricing & Plans:** Freemium. The extension is free to install from the Chrome Web Store, with premium AI features typically offered through a paid tier. Because the developer's own site was unreachable at the time of review, check the listing or the in-extension upgrade screen for current pricing.

- **Smart Tags and Categories:** Saved pages are automatically categorized and tagged by topic and theme, so bookmarks stay organized without manual filing.
- **AI Summaries and TLDRs:** Generate a quick summary of any saved article so you can grasp its main points in under 30 seconds.
- **Full-Text and Filter Search:** Retrieve any bookmark using a text query, tag, or filter combination, even from a half-remembered phrase.
- **Tab and Session Management:** Save open tabs as a session and restore them later, picking up exactly where you left off.
- **Personalized Recommendations and Alerts:** Get content suggestions matched to your interests and reminders to finish articles or videos you left incomplete.

**Strengths:** Automated tagging and categorizing remove the manual work of keeping bookmarks tidy; AI summaries make it fast to triage long articles; Search covers full text, tags, and filters, which is far beyond the default browser bookmark search; Tab and session management is bundled in the same extension

**Limitations:** The developer's standalone website was unreachable during review, making current pricing and documentation hard to confirm; Effectiveness depends on how much content you routinely save, so light bookmark users may see limited benefit
