Your Content, Organized. Finally.

ContentMK is the desktop content management platform that replaces spreadsheets, browser tabs, and scattered tools with one app. Track every article across every site. Know what needs updating, what’s performing, and what’s missing.

What Is ContentMK?

ContentMK is a desktop application for content managers, SEO professionals, and digital publishers who run content across multiple websites. It pulls together content tracking, planning, SEO analysis, internal linking, WordPress management, and revenue analytics into a single modular platform.

Built for macOS and Windows, ContentMK stores all data locally in a SQLite database at ~/ContentMK/data.db. The app runs an Express API server on your machine, so you get instant access to your content data without internet latency or cloud service dependencies.

Who Is It For?

How It Works

1. Add your sites. Enter your website name, URL, and pick a color. Each site gets its own dashboard, article list, sync settings, and module configuration.
2. Import your content. Pull articles from WordPress via the REST API, crawl your sitemap, or upload a CSV. Duplicate detection prevents double-entries.
3. Track and manage. Every article has a status (Published, Draft, Needs Review, Out of Date), health score, categories, and notes. Age-based auto-status detection flags stale content automatically.
4. Extend with modules. Activate free modules for content planning, SEO metadata, internal linking, and social sharing. Add paid modules for SEMrush/Ahrefs data, revenue analytics, WordPress publish-back, and more.
5. Keep everything synced. The WordPress Sync Engine maintains a live connection to your WordPress sites. You’ll know instantly when content changes on either side.

Core Features (Included in All Plans)

Multi-site workspaces

Manage any number of websites from a single app. Each site has its own dashboard with article stats, sync status, and recent activity. You get article lists with sorting, filtering, and search. WordPress sync configuration per site. Module activation per site. Custom color coding for visual identification. Configurable freshness thresholds (for example, 3 months = needs review, 6 months = out of date).

The sidebar switches between an “All Sites” overview and a per-site hub with six sections: Dashboard, Articles, Planning, Sync, Backups, and Settings.

Article tracking

Every article is tracked with a title and URL (unique constraint per site to prevent duplicates), status (Published, Draft, Needs Review, Out of Date with auto-detection by age), health score (0-100 composite that adapts to active modules), categories for organization, last updated date that drives auto-status detection, and a free-text notes field.

The article list uses TanStack Table with sortable columns and client-side search. Filtering is instant on title, URL, and categories starting at 3 characters.

Content health score

A multi-factor 0-100 score that tells you at a glance how healthy each article is:

Factor	Weight	What it measures
Freshness	40%	Days since last update vs. site threshold
SEO completeness	25%	Target keyword, search volume, keyword difficulty filled in
Internal links	20%	Inbound + outbound links vs. site average
Social engagement	15%	Shared on N platforms

The score adapts to which modules are active. If you don’t use the Social Sharing module, that 15% redistributes to other factors. Freshness always carries at least 50% weight.

Auto-status detection

Articles automatically transition to “Needs Review” or “Out of Date” based on their age relative to configurable per-site thresholds. A news site might flag articles after 1 month. An evergreen resource site might use 6-month and 12-month thresholds.

Full-text search

SQLite FTS5 powers full-content search across all articles. Search titles, URLs, notes, categories, and article body text.

Data export

Export your data in JSON, CSV, PDF, or HTML format. Export is always available, even if your subscription lapses.

WordPress sync engine

A core service (not a module) that provides a unified WordPress REST API client. All WordPress-related modules share this engine.

The Sync page shows connection status, sync statistics (total tracked, synced, local changes, conflicts), and a changelog timeline with the ability to revert individual changes.

Manual Import fallback: When WordPress sync isn’t available (no API access, non-WordPress sites), a collapsed section on the Sync page provides CSV and Sitemap import wizards as an alternative.

Backups & restore

Comprehensive local backup system built into every site:

Cloud Sync ($25/mo) extends this with offsite backups, multi-device sync, and scheduled cloud backup operations.

Activity log

Every change across the app is logged: article creates, updates, deletes, imports, sync operations, module activations.

Dark mode

Dark mode is the default, with a light mode toggle in the sidebar. Theme persists across sessions via localStorage.

Free Modules (8 Modules, Included With All Plans)

Free modules ship with the app and can be activated per-site at no cost. They provide the full content management workflow out of the box.

Content planning

A complete content planning suite for editorial workflows:

• Content Ideas. Idea backlog with a status workflow: Idea, Researching, Planned, In Progress, Published. Each idea has title, status, priority, and notes. Ideas link to articles when published.
• Content Clusters. Group articles and ideas by topic for authority building. Visual coverage tracking per cluster.
• Update Scheduling. Assign update frequency to articles (weekly, monthly, quarterly, biannual, yearly). Track next due date. Overdue items surface on the dashboard.
• Content Briefs. Create structured briefs with target keyword, search intent, suggested outline, target word count, tone notes, competitor URLs, and internal linking targets. Briefs auto-populate from other active modules when available. Export as Markdown or PDF for writer handoff.

Import tools

Three methods to get existing content into ContentMK:

All three methods share a common article inserter with URL-based duplicate detection. Import history tracks every import with source, count, and undo capability.

Basic SEO

SEO metadata tracking with WordPress SEO plugin integration:

• Per-article fields: target keyword, search volume, keyword difficulty (0-100)
• Per-idea fields: same fields plus secondary keywords and competitor URLs for research
• WordPress SEO plugin integration. Auto-detects which SEO plugin your site uses (Yoast, Rank Math, SEOPress, or AIOSEO) and pulls SEO titles, meta descriptions, canonical URLs, Open Graph data, robots directives, and schema markup directly from the plugin. No extra configuration needed.
• Schema markup tracking. Track which articles have structured data (FAQ, HowTo, Article, Review, Product, Recipe, etc.). Auto-detect from article content (parses JSON-LD blocks) and from WordPress SEO plugins. Coverage dashboard with per-type breakdown.
• SEO completeness indicator. Per-article colored badge showing how many fields are filled. “Missing SEO data” and “Missing schema” filters in the article list. Feeds into health score (25% weight).
• Source tracking. Every SEO field shows where its data came from (manual entry, Yoast, SEMrush, etc.). Manual edits always take priority over plugin or premium module data.

Interlink manager

• Manual link tracking. Track which articles link to which, with anchor text. Inbound and outbound link lists per article.
• Auto-suggestions. Three-layer algorithm: cluster/category matching, FTS5 content overlap, and link gap analysis (articles with zero links).
• Suggestion tracking. Each suggestion can be accepted or dismissed. Progress tracking (“X of Y suggestions implemented”).
• Health score integration. Link count relative to site average feeds the 20% links factor.

Social sharing

• Configurable platforms. Default: Facebook, Reddit, LinkedIn, Pinterest, X/Twitter. Add, remove, or reorder per site.
• Share history. Multiple shares per article per platform (for re-sharing evergreen content). Each share records timestamp, optional post URL, and notes.
• Filters. “Unshared” filter (articles not shared anywhere), “Ready to reshare” filter (last share > N months ago).
• Health score integration. Share coverage across platforms feeds the 15% social factor.

Article types

• Built-in types: Review, Guide, News, Feature, How-To, Comparison, Listicle, Explainer, Roundup, Event, Recall, Podcast, Opinion, Interview, Case Study
• Custom types. Add site-specific types beyond the defaults.
• Visual integration. Color-coded type badges on article cards. Filter by type with counts. Distribution chart on dashboard.

WordPress tag manager

Full bidirectional WordPress tag and category management via the Sync Engine:

• Tag catalog sync. Pull all tags and categories from WordPress with article counts.
• Issue detection. Typo detection (fuzzy matching), duplicate detection (case/hyphen variants), orphan tags (zero articles), thin tags (one article), overly broad tags (50+ articles).
• Write operations. Rename, delete, merge tags directly from ContentMK. Rate-limited batch operations.
• Tag gap analysis. Per-article three-way analysis: matched (correct), missing (should be added), extra (should be removed). One-click “Apply Missing” action.
• Naming conventions. Flag inconsistent casing, suggest standardization.

Claude Code integration

• Phase 1 (current): Structured exports. Export site data as JSON or Markdown files optimized for AI prompt workflows. Article inventory, content gaps, cluster maps, idea backlogs, linking opportunities, health summaries. Written to ~/ContentMK/exports/ for easy access.
• Phase 2 (planned): MCP server. Expose ContentMK data via Model Context Protocol. Claude Code connects directly to query articles, update statuses, add ideas, and run analysis.

FAQ

Can I use ContentMK without WordPress?

Yes. ContentMK works with any website. Import articles via CSV or sitemap crawl. The WordPress sync features are optional. The core app tracks content regardless of your CMS.

What happens to my data if I cancel?

Your data stays on your machine. The SQLite database at ~/ContentMK/data.db is yours. Export is always available, even after cancellation. The app enters read-only mode after a 7-day grace period, but your data is never deleted or locked away.

Can I use it on multiple computers?

Your license works on unlimited machines. Without the Cloud Sync module, each machine has its own independent database. With Cloud Sync ($25/mo), data syncs between all your devices automatically.

Do I need both SEMrush and Ahrefs modules?

No. Most users subscribe to one SEO tool or the other. Each module is independent. If you use SEMrush, get the SEMrush module. If you use Ahrefs, get that one. Both support CSV import and live API modes.

Is my WordPress password stored securely?

WordPress Application Passwords are encrypted at rest using your operating system’s secure credential storage (Electron safeStorage). They are stored locally in your SQLite database on your machine and never transmitted to our servers. The API endpoint that checks credential status never exposes the actual password. It only returns a boolean flag indicating whether a password is configured.

Which WordPress SEO plugins does ContentMK support?

ContentMK’s Basic SEO module automatically detects and integrates with the four most popular WordPress SEO plugins: Yoast SEO, Rank Math, SEOPress, and All in One SEO (AIOSEO). Detection happens automatically when you connect your WordPress site. No extra configuration needed. If auto-detection gets it wrong, you can manually select your plugin in Site Settings. ContentMK reads SEO titles, meta descriptions, canonical URLs, Open Graph data, robots directives, and schema markup from whichever plugin your site uses.

Can I use SEMrush and Google Search Console together?

Yes. Each premium module enriches the same underlying SEO data independently. When you have both SEMrush and GSC active, you can compare estimated rankings (from SEMrush) with actual Google positions (from GSC) side by side. The same applies to Ahrefs + GSC. All data appears in a unified article view with clear source labels showing where each data point comes from.

Can I try a paid module before buying?

Paid modules show a preview of what they do within the app. You can see exactly what features you’ll get before purchasing. We don’t offer time-limited trials, but you have a 30-day money-back guarantee on everything.

How often does ContentMK update?

Updates are delivered automatically via GitHub Releases and Electron’s built-in auto-updater. Database migrations run automatically with a silent backup before each migration.
