## 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

## TwinMind

TwinMind is positioned as an AI second brain rather than a single-purpose note taker. It captures your day across meetings, calls, lectures and casual conversations on your own devices, transcribes everything in 140+ languages, and turns the raw audio into structured summaries, action items and daily digests. By evening, what you lived is sorted by people, places and projects into a private wiki you can search later.\n\nIts differentiating layer is context. Through an MCP connection, TwinMind feeds your conversations, email and the web into ChatGPT, Claude and Gemini so those assistants answer with knowledge of your actual life instead of generic predictions. The same context powers 'prepare and create' flows: a morning list of priorities, a drafted reply to the email you were dreading, or a deck built from a sales call without writing a prompt.\n\nPrivacy is handled explicitly. Capture is manual by design — no bot joins your calls and the microphone is off when you are not recording. On-device mode keeps sensitive data entirely local, audio is deleted after transcription by default, and TwinMind says your data is never sold or used to train AI models. It holds SOC 2 Type II and Google CASA Tier 2 credentials and reports use by over 500,000 people. Pricing runs from a permanent free tier to Pro and Max subscriptions, with enterprise controls available.

**Pricing & Plans:** Freemium. Free $0 forever includes AI summaries, AI chats, daily digests and transcription. Pro is $11.99/month billed annually and adds unlimited transcription, ChatGPT/Gemini/Claude access, Apple Watch capture and audio uploads. Max is $29.99/month billed annually with 5x limits, auto-tagging and draft emails, advanced AI models, unlimited MCP and speaker separation. A 7-day free trial is offered, and enterprise custom pricing is available on request.

- **Always-on transcription:** TwinMind records in-person conversations, meetings and lectures, transcribing in 140+ languages with automatic detection and optional real-time translation.
- **Summaries & daily digests:** Every capture turns into clear summaries, daily digests and recaps, with a morning brief that surfaces your top priorities and a pre-written draft email.
- **Personal second brain:** Capture is organized automatically by people, places and projects, building a private wiki of your life you can search and revisit at any time.
- **MCP for ChatGPT, Claude & Gemini:** A TwinMind MCP connection gives ChatGPT, Claude and Gemini the context of your conversations, email and web so answers reflect your actual life.
- **Privacy by design:** On-device mode keeps private data off the cloud, audio is deleted after transcription by default, and TwinMind states your data is never sold or used to train AI models.
- **Capture on every device:** Available as a Chrome extension, Mac and Windows desktop apps, iPhone app and Apple Watch capture, with no bot joining your calls.

**Strengths:** Turns raw conversations into summaries, action items and a searchable personal knowledge base; 140+ language transcription with automatic detection and real-time translation; MCP integration supplies real personal context to ChatGPT, Claude and Gemini; Strong privacy posture: no meeting bot, on-device mode and audio deleted by default

**Limitations:** Best experience depends on installing extension and desktop/mobile apps across devices; Gemini, ChatGPT and Claude integration is limited to a set number of tool calls on Free and Pro; Mobile meeting apps are not captured directly; Advanced models and email drafting sit behind the most expensive tier
