Capacities Review 2026 - Object-Oriented Notes
Verified Jun 6, 2026 by Tooliverse Editorial
Capacities replaces folders with objects—people, books, projects—that link automatically and surface forgotten connections. Writers, researchers, and knowledge workers use it to build a second brain without the setup overhead of traditional PKM tools.
Capacities Review: Tooliverse Consensus
Based on 2k+ verified reviews across 5 platforms,
combined with Tooliverse's expert analysis
Capacities treats information as interconnected objects instead of files in folders, creating automatic bi-directional links that mirror how knowledge workers actually think about complex topics. The object-oriented architecture and polished interface set it apart for researchers and writers managing long-term knowledge bases, with AI that surfaces non-obvious connections instead of just generating text. The learning curve is real—mastering the object workflow takes meaningful upfront investment—and mobile performance lags the desktop experience during heavy use, but users who commit to the system report it fundamentally changes how they organize information.
Bottom line: A top-tier personal knowledge management platform that mirrors how your brain connects information through object-based organization, though the learning curve and mobile performance require patience from new users.

Capacities Features 2026
Object-Oriented Note System
Create custom object types (people, books, projects, recipes) with their own properties, templates, and structure. Everything becomes a real thing, not just a file in a folder.
Bi-Directional Linking
Type a name or reference and Capacities creates automatic two-way links. The backlinks panel shows every object that references the current one, surfacing connections you forgot you made.
Related Content (Pro)
Capacities automatically scans your notes and surfaces places you wrote about something but never linked—connections you already made, found automatically.
Graph View
Visualize your entire knowledge network as a living graph. Explore connections, spot clusters, and find unexpected patterns across all your objects.
Capacities User Reviews
Selected Reviews
"Switched from Notion and haven't looked back. The "everything is an object" philosophy is much more powerful for long-term knowledge."
"Finally a tool that understands that a "Book" and a "Person" are different types of things. The properties system is brilliant."
"I love the daily notes integration. It's so easy to link tasks and thoughts to specific days without losing them in a folder."

Capacities Pricing 2026
View SourceThe free tier is surprisingly capable—unlimited objects and full bi-directional linking with 5GB storage covers casual users indefinitely. Pro at $9.99 monthly is where most serious knowledge workers land: the AI assistant that surfaces hidden connections, smart queries for filtering your knowledge base, and calendar integration that threads temporal context through everything. The 16% annual discount brings it to $8.39 monthly if you're committed. Believer at $12.49 monthly adds beta access to major features, worth it only if you want to influence the product roadmap.
Capacities In-Depth Review 2026

The platform runs on web, iOS, Android, macOS, Windows, and Linux with sync across all devices. What sets it apart is the object-oriented architecture: create a "Book" object type with properties for author, rating, and publication date, and every book you add inherits that structure. Mention an author's name anywhere in your notes, and Capacities automatically links to their object, building a web of connections without you thinking about it. It's the difference between maintaining a library catalog and just writing naturally while the system handles the relationships.
What It's Like Day-to-Day
The interface is polished enough that it changes how you feel about writing. Clean typography, thoughtful spacing, and smooth animations make opening the app feel less like launching software and more like sitting down with a good notebook. That matters more than it sounds like it should—when a tool looks this good, you actually want to use it daily instead of letting notes pile up in a text file somewhere.
