## 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

## ResearchRabbit

ResearchRabbit is a free tool designed to make literature reviews faster and less overwhelming. Instead of dumping keyword results into a flat list, it turns a single paper you trust into an interactive map: you see related works, who cites whom, which authors are central, and where the field branches. The aim is to let your curiosity drive discovery rather than forcing you to guess the right search terms.

The engine is built on iterative chaining. It analyses a seed paper's bibliography, citations and co-authors to recommend related articles, and as you save and explore new papers the recommendations adjust to your interests. You can also connect your existing reference library so ResearchRabbit and your collection work together, making it easier to see how a literature review connects.

Scale is a core part of its pitch: ResearchRabbit reports being trusted by over one million researchers worldwide, with access to more than 320 million academic papers, and adoption across institutions ranging from Deakin and Monash to Cornell, Stanford and Harvard. It is operated by Litmap Limited and maintains a free sign-up flow.

**Pricing & Plans:** Free. ResearchRabbit is free to sign up and use for literature discovery and mapping, with no paid consumer plans advertised on its site. Recommendations run on publicly available scholarly metadata covering over 320 million papers.

- **Visual Paper Mapping:** Start from one paper and see how research connects through a visual map of related works, authors and citations.
- **Recommendation Engine:** The more you explore and select, the better it learns your interests, surfacing smarter and more relevant recommendations.
- **Literature Review Discovery:** Explore how your existing review connects and discover papers you may have missed, avoiding endless flat article lists.
- **Reference Manager Integration:** Bring your reference library and ResearchRabbit together so your collection and discovery work in one place.
- **Author & Topic Tracking:** Follow new works, emerging authors and trending topics as your research field evolves.

**Strengths:** Completely free to sign up and use; Visual, iterative maps beat long flat article lists for exploring a field; Learn-as-you-go recommendations improve with use; Integrates with your existing reference library

**Limitations:** It surfaces and maps papers rather than reading them for you—no automatic summarisation of full texts; No built-in full-text access; you still need your library or publisher access to read the papers; Deeper use benefits from connecting a reference manager, which adds a setup step; Some advanced collaboration and sharing features sit behind institutional or optional arrangements
