Contentpen and Vulcaro both use AI to produce SEO blog content — but they approach the problem very differently. One is a writing assistant that helps you create articles faster. The other automates your entire SEO strategy from start to finish. Here's the full breakdown.
The Core Difference
Contentpen is an AI writing tool with SEO features layered on top. You bring the keyword, it helps you produce a well-structured article. It's fast, it's guided, and it integrates with Google Search Console to surface content opportunities.
Vulcaro is a full SEO automation system. It doesn't wait for you to pick a keyword — it maps your competitors, finds your gaps, plans 90 days of content, and publishes to your CMS without you lifting a finger. You're not just writing faster; you're removing yourself from the process entirely.
If you're evaluating Contentpen alternatives that go beyond assisted writing, Vulcaro is the clearest step up.

What Is Vulcaro?
Vulcaro is an AI-powered SEO automation platform built around 10 specialised AI agents. Once you connect your website, it runs your entire content operation automatically:
- Analyses your site and maps your top competitors
- Identifies keyword gaps — terms your competitors rank for that you don't
- Groups keywords into topical clusters for authority building
- Generates a 90-day publishing calendar with prioritised topics
- Writes each article, generates on-brand images, and publishes to your CMS
You choose between Autopilot mode (zero involvement — Vulcaro runs everything) or Human-in-Loop mode (you review each article before it goes live). Either way, the research and strategy is handled for you.

What Is Contentpen?
Contentpen is an AI blog writer launched in 2025, built around a multi-agent content pipeline. Each stage of article creation — research, outlining, writing, SEO optimisation, and QA — is handled by a dedicated AI agent.
The standout feature is its two-step workflow: Contentpen first generates an editable outline (based on SERP analysis and your brand voice), then produces the full article once you've approved the structure. This keeps you in control of the angle and direction before AI commits to the full draft.
Contentpen also connects to Google Search Console with an Opportunities Dashboard that surfaces content decay and keyword wins. Its Article Refresher feature re-optimises existing posts — something Vulcaro doesn't currently offer.
Pricing Comparison
| Plan | Vulcaro | Contentpen |
|---|---|---|
| Starter | $49/mo | $39/mo — 10 articles |
| Mid-tier | $99/mo | $79/mo — 30 articles |
| Agency | — | $199/mo — 100 articles |
| Annual discount | — | 30% off |
| Trial | 3 days for $1 | 3 free articles |
Contentpen is cheaper at entry level — $39/mo vs $49/mo — and offers 3 free articles with no credit card. Vulcaro's $1 trial gives you access to the full platform including the strategy and automation layer, not just article generation.
The more important pricing question: how much is your time worth? Contentpen still requires you to manage keyword selection, approve outlines, and schedule publishing. Vulcaro handles all of that for you.
Integrations
Both tools support the major CMS platforms. Contentpen has a slight edge with Ghost and Wix support; Vulcaro covers GoHighLevel which Contentpen doesn't.
| Platform | Vulcaro | Contentpen |
|---|---|---|
| WordPress | ✅ | ✅ |
| Webflow | ✅ | ✅ |
| Shopify | ✅ | ✅ |
| GoHighLevel | ✅ | ❌ |
| Ghost | ❌ (roadmap) | ✅ |
| Wix | ❌ (roadmap) | ✅ |
Who Should Use Each Tool?
Choose Vulcaro if:
- You want fully automated SEO — research, writing, and publishing handled for you
- You don't want to manage keyword selection or content planning manually
- You're on WordPress, Webflow, Shopify, or GoHighLevel
- You want a system that compounds over time with topical authority
- You want to try the full platform for $1 before committing
Choose Contentpen if:
- You want editorial control at the outline stage before AI writes the full draft
- You have existing content that needs refreshing and re-optimisation
- You publish on Ghost or Wix
- You prefer a lower entry price and want to start with 3 free articles
- You have an in-house SEO team managing keyword strategy
The Verdict
Contentpen is a solid AI writing tool — particularly strong for teams who want to stay involved in the content process and need a Google Search Console-connected workflow. The Article Refresher is a genuine differentiator for sites with existing content to optimise.
But Contentpen is still fundamentally an assisted writing tool. You bring the strategy; it helps with execution.
Vulcaro is built for business owners who don't want to be the strategist. It handles competitor research, keyword gaps, content planning, and publishing automatically — so you can focus on running your business instead of managing an SEO calendar.
If you're looking for a Contentpen alternative that removes you from the SEO workflow entirely, try Vulcaro for $1 and see what a fully automated system looks like.
