Capacities vs Obsidian

Obsidian is a powerful, local-first note-taking app beloved for its plugin ecosystem and plain Markdown files. Capacities is a focused knowledge studio built around connected objects. Both are excellent tools for personal knowledge management — but they take fundamentally different approaches. This comparison helps you decide which one fits your workflow.

What each excels at
Strengths
Every tool has areas where it shines. Here's an honest look at what each product does best.
Capacities
Works beautifully out of the box
No plugins to install, no templates to find, no folder structure to plan. The object-based model provides meaningful structure from day one.
Typed objects give your notes meaning
People, books, projects, and ideas are first-class citizens with their own properties — not just files in folders with YAML frontmatter.
Seamless sync across all devices
Built-in cloud sync works across all platforms without extra cost or configuration. No iCloud errors, no Dropbox conflicts.
Approachable for non-technical users
Users consistently describe Capacities as more intuitive and less 'techy' than Obsidian, making knowledge management accessible to everyone.
Context-aware AI built in
AI that understands your connected notes and backlinks, included natively in Pro — no plugins or external tools needed.
Obsidian
Massive plugin ecosystem
Over 2,000 community plugins extend Obsidian in virtually any direction — from Dataview queries to Kanban boards to AI assistants.
True local-first with plain Markdown
Your notes are standard .md files on your device. No vendor lock-in, no cloud dependency, full ownership and portability.
Free core with no feature gates
The full app is free for personal use. You only pay for optional sync and publish services.
CLI and AI agent compatibility
Plain Markdown files integrate directly with Claude Code, Cursor, and custom scripts — enabling powerful agentic workflows without an API.
Canvas for visual thinking
Built-in Canvas lets you spatially arrange notes, images, and connections on an infinite whiteboard.
Honest trade-offs
Known Limitations
No product is perfect. Here are the common frustrations users report for each tool.
Capacities
No local file access
Common issueNotes are stored in Capacities' cloud, not as files on disk. Users who value plain-text portability or want to use CLI tools directly on their notes find this limiting.
No plugin ecosystem
ModerateCapacities provides built-in features but no plugin API. Power users who rely on custom extensions and community tools may feel constrained.
Smaller community
ModerateAs a younger product, Capacities' community, tutorial ecosystem, and template library are still growing compared to Obsidian's 300k+ member community.
Missing canvas / spatial view
ModerateNo visual canvas for spatial mapping — a feature Obsidian users often rely on for brainstorming and connecting ideas visually.
No E2EE; hosted data model
Common issueCapacities is purposefully not end-to-end encrypted so sync, search, and integrations can work. If a local-only vault or E2EE is non-negotiable, the tradeoff versus Obsidian is structural, not a missing toggle.
Obsidian
Setup and maintenance overhead
Common issueGetting Obsidian to work well requires finding, installing, and maintaining plugins, configuring templates, and building a folder/tag structure. Many users report spending more time tinkering than writing.
"After seeing Capacities, I'm leaning towards this more because it flows better and doesn't feel so 'crunchy' as Obsidian does when many use-cases are build-it-yourself."
— Discord
"I just could not get my mind around Obsidian — it was a product fit issue more than anything."
— Discord
Sync costs money or requires workarounds
Common issueCross-device sync requires Obsidian Sync ($5/mo) or DIY setups with iCloud, Dropbox, or Syncthing — each with its own reliability issues.
"I cancelled my Obsidian Sync and moved over completely to Capacities."
— Discord
Mobile experience can be sluggish
ModerateWhile feature-complete on mobile, users frequently report slower performance and a less polished experience compared to the desktop app.
Steep learning curve for non-technical users
ModerateObsidian's power comes from customization, but that same flexibility makes it intimidating for users who aren't comfortable with Markdown, YAML, or plugin configurations.
"Obsidian is definitely a programmer's/tech-minded note-taking tool. Capacities flows better and doesn't feel so crunchy."
— Discord
"I used Obsidian before too but it was a bit too techy for me. Capacities is a mix of Obsidian and Notion — it's a lot more approachable."
— Discord
