Introducing the Free SEO & Readability Assistant SPA — Boost Your Content Quality in Real-Time
Creating content that ranks high on search engines and remains easy to read is no easy task. That’s why I built this free Vue-based SEO & Readability Assistant SPA — a lightweight, fully client-side tool that helps you optimize your titles, descriptions, and content structure on the fly.
Optimize Content with Confidence — Free Vue SEO and Readability Assistant SPA
This tool was designed for writers, marketers, developers, and content creators who want instant, actionable feedback on their content before hitting publish. Whether you're drafting a blog post, a landing page, or SEO metadata for a product, this assistant gives you real-time insights on both SEO best practices and readability standards.
With a built-in CKEditor 5 interface, you can write and format your content exactly as it will appear. The assistant instantly evaluates things like:
- SEO title length and focus keyword presence
- Meta description length and keyword inclusion
- Internal and external links
- Use of images with alt attributes
- Content length (with word counter)
- Keyword placement in intro paragraphs
- Readability score (Flesch Reading Ease)
- Detection of passive voice and long sentences
Each issue is paired with specific tips — and for long or passive sentences, you’ll see sample snippets to improve. A color-coded score meter helps you understand your content health at a glance.
Best of all? It's free, downloadable, and requires no backend — just open it in a browser and start optimizing.
🚀 Try it out, improve your SEO instantly, and download the source — all free and open.

📣 Why I Built It
As a full-stack developer working on SEO-heavy platforms, I often needed a quick, local tool to evaluate content quality without relying on browser extensions or heavy SaaS platforms. So I made one — and now I’m sharing it with you. No tracking. No data storage. Just fast feedback to improve your writing.
