Obsidian is a markdown‑based note‑taking app that many writers use to outline, research, and draft. In 2026 the platform offers three official add‑ons that directly affect a writer’s workflow: Obsidian Publish, Obsidian Sync, and the Catalyst membership. This guide explains which of these tools works best for different writing styles, compares price and features, and answers the most common questions.
Obsidian Publish turns a vault folder into a static website. You write in markdown, and Publish builds HTML pages, a navigation sidebar, and a search index automatically.
Obsidian Sync is an end‑to‑end encrypted cloud service that syncs your vault across devices. It also stores a full version history for each file.
Catalyst is a membership program that gives early access to new core features, priority support, and a share of community‑generated revenue.
| Product | Core Feature | Price (2026) | Best For | Downsides |
|---|---|---|---|---|
| Obsidian Publish | Static website publishing from any vault folder | $8 / month (unlimited) or free tier (3 pages) | Writers who want an online portfolio or serial publishing | Public by default; limited e‑commerce |
| Obsidian Sync | End‑to‑end encrypted multi‑device sync + 30‑day history | $8 / month or $80 / year | Freelancers who work on multiple devices | No free option; depends on internet |
| Obsidian Catalyst | Beta plugin access, priority support, 90‑day history | $25 / year (one‑time) | Power users who rely on plugins and want early features | Indirect benefits; early features may be buggy |
Obsidian Sync encrypts each note end‑to‑end and resolves conflicts better than generic cloud sync. It is worth the $8/month if you need reliable version history and conflict‑free merging.
Obsidian Publish lets you turn any vault folder into a static website. You can embed markdown, images, and even embed Excalidraw diagrams. It is ideal for serial publishing or a writer’s portfolio.
Start with the free core app, add Obsidian Sync ($8/month) for backup, and skip Publish until you have a finished manuscript. This combo costs less than $100/year.
Catalyst gives early access to new plugins, priority support, and a share of community revenue. For writers who rely on plugins like Dataview or Advanced Tables, the $25/year can save hours of workflow tweaking.
Publish hosts static HTML on Obsidian’s CDN. Files are not searchable by default, but you should still treat it as public. Use a private sub‑domain or password‑protect pages if you need extra security.
Choosing the right Obsidian add‑on depends on how you write. Sync protects your drafts, Publish showcases finished work, and Catalyst keeps you on the cutting edge. Most writers benefit from a combination of Sync and Publish, while Catalyst adds optional power for plugin‑heavy workflows. Evaluate your budget, workflow, and publishing goals, then pick the plan that matches your needs.
