Built a fast Word Counter micro-tool using AI & JS (Vibe code) —would love your feedback!

by•

Hey Product Hunt community! 👋

As an SEO specialist and builder, I frequently need a quick, reliable word-counter tool to check content limits, character counts, and estimated reading time during optimization workflows.

Instead of relying on heavy third-party sites with cluttered interfaces, I decided to vibe-code my own dedicated client-side solution focused on speed and real-time processing.

Key features built-in:

  • Real-time metrics: Counts words, characters, sentences, paragraphs, and lines instantly as you type.

  • Time estimation: Calculates average reading and speaking duration for content planning.

  • Zero processing latency: Runs 100% client-side with clean JavaScript for fast execution.

I built this using PHP and vanilla JS to keep it lightweight and responsive. You can test the tool directly here:

Question for fellow makers: If you build or regularly use micro-tools for writing and content analysis, what additional metrics or features do you find most useful in your daily workflow? Would love to hear your thoughts and suggestions! 🚀

Always open to honest feedback, feature requests, or bug reports. Let me know what you think, and share what you're working on as well! 🚀

Thanks for checking it out! I'm planning to add a keyword density analyzer in the next iteration. Feel free to leave any feedback or share what micro-tools you're currently building as well!
