Logseq vs Capacities

Logseq is a free, open-source, local-first outliner with flashcards and a privacy-first ethos; Capacities is an object-based notes studio where every note is a typed thing — a person, a book, a meeting. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

What is Logseq?

Logseq is the open-source counterpart to Roam: an outliner built on bidirectional links and daily notes, but storing everything as local Markdown (or Org-mode) files on your device. It’s free, AGPL-licensed, and adds flashcards with spaced repetition, PDF annotation, queries, whiteboards and a plugin ecosystem. Sync is available end-to-end encrypted, or you can roll your own with Git or Syncthing.

The project is mid-transition: alongside the classic Markdown version, a rebuilt “DB version” backed by a local database entered public beta in July 2026, bringing real properties and Tana-style structured tags plus more reliable sync. That rewrite consumed several years of development attention, so the classic version evolved slowly — but the foundation of free, local, open-source outlining has kept a devoted community.

What is Capacities?

Capacities organizes your knowledge by what things are. Instead of files in folders, you create objects — people, books, meetings, projects, quotes — each with its own properties and views, connected through backlinks and daily notes. Browsing by object type (every book you’ve noted, every person you’ve met) falls out of the design for free, and a calendar-centric daily view ties it to your day.

It’s a polished, cloud-based app on web, desktop and mobile, with a generous free core plan; Pro (about $10/month billed annually) adds the AI assistant, calendar sync and advanced queries. In July 2026 it shipped a developer API with OAuth, opening it up to integrations. One deliberate omission to know about: there is no collaboration, and the team has said it isn’t planned — Capacities is intentionally a personal tool.

Logseq vs Capacities at a glance

Pricing and features as of mid-2026 — check each product’s site for current details.

Where Logseq shines

• Free and open source (AGPL) with local-first storage — the strongest ownership story among outliners.
• Built-in spaced-repetition flashcards and PDF annotation, no plugins needed.
• Block references, queries and whiteboards cover most of Roam’s power features.
• The new DB version adds structured properties and tags with trustworthy sync.

Worth knowing: No real-time collaboration — it’s a single-player tool. The MD-to-DB transition splits the product; some features (like whiteboards) are temporarily missing from the DB beta. Polish and mobile experience trail the paid competition, and web capture relies on community tooling.

Where Capacities shines

• Object types with properties give structure without the rigidity of databases or the chaos of free-form notes.
• One of the most polished, beautiful interfaces in the category, consistent across web, desktop and mobile.
• A genuinely useful free plan, with Pro at a mid-pack price.
• Daily notes plus calendar integration make it a natural journal-of-record.

Worth knowing: No collaboration — explicitly not supported and not planned; sharing is read-only page links. Cloud-first and proprietary, with no local-first storage or end-to-end encryption. Power features like queries sit behind Pro, and the object model can feel like ceremony for quick, messy capture.

Which should you choose?

Choose Logseq if:

• You want Roam-style outlining without the subscription, as open-source software.
• Local files and end-to-end-encrypted sync are non-negotiable.
• You want flashcards built into the same tool as your notes.

Choose Capacities if:

• You think in entities — people, books, meetings — and want your tool to as well.
• Interface polish and aesthetics genuinely affect whether you’ll keep using a tool.
• You’re strictly solo and don’t need sharing or teamwork.

A third option: Dexi

If what you actually want is one searchable place for notes, bookmarks, newsletters and RSS — with tags, @mentions and [[wiki links]] that organize themselves as you write, semantic search that finds ideas even when the words don’t match, and an MCP server so Claude and other AI assistants can work with your notes directly — take a look at Dexi. It’s free for up to 1,000 notes, with no app to install.
