What is Capacities?
Capacities is a note-taking and knowledge management app from Capacities Labs GmbH that organizes notes as typed objects (such as people, books or meetings) in spaces. It includes an AI assistant for chat, summaries, auto-tagging and property auto-fill, and runs on web, Windows, macOS, Linux, iOS and Android.
Who it's for
It suits people who want to link notes, tasks, calendar events and saved media in one app; the vendor's pricing page lists Pro for professionals. It is not aimed at teams needing a shared admin product; the pricing page lists only individual plans.
Pros & cons
Strengths
- The vendor lists the free Basic plan with unlimited spaces, objects, blocks and custom object types, plus cross-device sync, offline support, full-text search and import/export.
- The product page lists integrations including WhatsApp, Telegram and email capture, Readwise, Kindle, Web Highlights, Raycast, and task push to Todoist, Things, TickTick, Apple Reminders, Google Tasks and Microsoft To Do.
- The AI assistant docs list AI chats with approval-gated edits, auto-tagging, property auto-fill, image analysis, image generation and query generation, with models from OpenAI, Anthropic, Gemini, xAI, Mistral, Deepseek and Moonshot.
- Capacities says your content is not used to train models, AI is fully opt-in and can be limited to selected spaces, and providers may keep data only for abuse monitoring, for up to 30 days.
- The facts page says user data is stored in the EU and lists export to Markdown, CSV, Word, HTML and LaTeX; the pricing page lists AI connectors that let ChatGPT, Claude, Le Chat and Cursor read from and add to a chosen space.
Limitations
- Basic includes 5 GB of media uploads in total, then 100 MB per month, and no AI assistant, Public API or other Pro features.
- Pro and Believer include a monthly AI budget that the docs describe as sized for trying AI or very light use; it resets each cycle and does not roll over, heavier models use it faster, and AI features pause when it runs out.
- Larger AI budgets and top-ups require the Plus add-on (Pro+ or Believer+), listed at $8.33 a month billed annually on top of the base plan; online search works only with the Capacities AI budget.
- Paid fees are generally non-refundable under the terms (EU residents have a 14-day withdrawal right unless they consent to immediate performance), and website or desktop subscriptions must be canceled at least 24 hours before the period ends.
- Unlimited media on paid plans is subject to fair use, commercial use must be part of your own business, and bulk imports of tens of thousands of documents are not allowed; users in countries Paddle does not support can only use Basic.
Plans and pricing
- Basic: $0. Unlimited spaces, objects and blocks; 5 GB media uploads, then 100 MB a month; view-only sharing; no AI assistant or Public API.

- Believer: From $12.49 a month on the pricing page; the facts page lists from $149.88 a year or $14.99 monthly. Same features as Pro plus beta access to major new features.
- Plus add-on (Pro+ / Believer+): $8.33 a month billed annually. Much larger monthly AI budget and top-ups, including auto top-up; requires an active Pro or Believer plan and is added at checkout.
Prices were read from the vendor's pricing page and the facts page, in USD. The pricing page shows $9.99 for Pro and a 'Billed yearly -16%' option without a yearly price; the facts page lists Pro at $11.99 monthly or $119.88 yearly, so $9.99 appears to be the annual-billing monthly equivalent. Docs say prices vary by region. Confirm on the live pricing page.
