Capacities

Capacities is a cross-platform note and knowledge-management app that connects offline notes with calendars, tasks, reading services and messaging tools. It is best suited to individuals building a connected personal system rather than teams editing the same document live. The free tier is useful for starting out, while the integrated task, calendar and AI features make the paid plans the more capable choice.

Overview

Capacities combines note-taking with a broad set of integrations and works on web, desktop and mobile devices. Offline access is important for commuters, travelers and anyone who cannot depend on a constant connection, while note sharing covers straightforward distribution to other people.

The limitation is collaboration: Capacities has no real-time collaboration. Sharing a note is suitable for sending information or handing off a document, but it is not the right model for colleagues who must edit together and see changes immediately.

Key features

The integration list is unusually wide for a note app. Capacities connects with Google Calendar and Microsoft Calendar, Readwise, WhatsApp, Telegram, email, Todoist, TickTick, Google Tasks, Microsoft To-Do, Things, Apple Reminders, Kindle, Raycast and Web Highlights. That makes it a credible central place for notes gathered from reading, communication and task systems, especially when your existing workflow already uses several of those services.

Most of that breadth has practical value on Pro rather than Basic. Calendar integrations, task management, smart queries and task actions are included with Pro, as is the AI assistant. Users who only want a simple offline notebook can stay on the free plan, but anyone expecting Capacities to coordinate tasks and calendars should budget for the subscription.

Pricing

Capacities Basic costs nothing. It provides 5 GB of media uploads in total, then permits 100 MB of media uploads per month. That initial allowance is generous for text-focused use, but the ongoing cap can become restrictive for users who regularly add images, audio or other media after exhausting the 5 GB.

Capacities Pro costs $9.99 a month, billed monthly. It adds task management, an AI assistant, calendar integrations, smart queries, task actions and unlimited media uploads subject to fair use. This is the plan for individuals who want Capacities to function as an integrated information and task workspace; “unlimited” still carries the fair-use qualification, so it should not be treated as an unrestricted media archive.

Capacities Believer costs $12.49 a month, billed from, and includes everything in Pro plus beta access to major new features. The extra cost is justified mainly for users who actively want early access; Pro offers the same core capabilities for everyone else.

The Plus AI Power-Up costs $8.33 a month, billed annually. It increases the monthly AI budget and adds AI top-ups. It is an additional AI-focused purchase for people who use the assistant heavily, rather than a replacement for Pro's broader productivity features.

Platforms

Capacities is available on Android, iOS, Linux, macOS, Windows and the web. That coverage suits households and individuals who switch between desktop and mobile operating systems, while offline access reduces dependence on browser connectivity.

Who it's for

Choose Capacities if you want a personal knowledge base tied to calendars, reminders, task managers, reading tools and messaging services, and you value access across nearly any mainstream desktop or mobile platform. Pro is the sensible starting point for users whose workflow depends on task and calendar connections or who need more media capacity.

It is a weaker fit for teams requiring simultaneous editing, for media-heavy users who cannot work within Basic's 100 MB monthly post-quota allowance, and for people who want those connected productivity features without a recurring payment.

Pros and cons

• Pro: Offline access across web, desktop and mobile keeps notes usable when connectivity is unreliable.
• Pro: Integrations cover major calendar, task, reading, messaging and utility services, reducing the need to keep related information isolated.
• Pro: The free plan includes 5 GB of media uploads before its monthly allowance begins, giving text-first users a substantial way to start.
• Con: There is no real-time collaboration, so shared notes cannot serve as a live team workspace.
• Con: Task management, calendar integrations, smart queries, task actions and the AI assistant require Pro, limiting the free tier's role in an integrated workflow.
• Con: Basic drops to 100 MB of media uploads per month after its 5 GB total, which can constrain regular media capture.

Alternatives

Notability is the better choice for users who want a freemium note app with a free trial and a free Starter plan limited to five notes, while retaining editing tools, PDFs, documents and templates.

Notion suits individuals seeking pages, blocks, databases and basic collaboration in its free plan, particularly when live teamwork matters more than Capacities' offline and integration emphasis.

Supernotes is worth considering for a card-based approach, with a free Starter allowance of 100 cards and an Unlimited plan priced at £6 a month when billed annually.

Zoho Notebook offers a free Essential plan with 500 MB cloud storage, 20 note versions and defined file and notecard size limits for users who prefer a simpler quota-based setup.

Craft is an alternative for users comfortable with a free plan capped at 1,500 blocks, 1 GB storage, 25 MB media uploads, seven days of version history and 15 AI assistant credits.

Goodnotes fits users who prefer notebook-style limits, with a free tier covering three notebooks, three text documents, three whiteboards, three folders and 100 MB storage.

HyNote is an alternative note-taking option with a free plan, audio recording and transcription, templates and a 120-minute-per-session limit.

Mem Agent is another freemium option for users interested in an AI-centered notes workflow.

Verdict

Capacities is a strong recommendation for an individual who wants offline notes connected to calendars, tasks, reading and communication services across every major platform. Choose Pro when those integrations, task controls, AI and higher media capacity are central to your workflow. Look elsewhere if real-time collaboration is essential or if you want the full connected feature set without a monthly subscription.
