I've built a (free) web tool that analyzes blog posts for HackerNews submission. It scores your content based on HN guidelines and provides actionable feedback to improve your post's success rate.

Key features:

- Analyzes title length, format, and capitalization

- Checks content depth and technical accuracy

- Validates against HN posting guidelines

- Provides specific improvement suggestions

- Real-time analysis in your browser

You can:

- Paste your blog post content directly

- Get instant feedback on title optimization

- Understand exactly what to fix before submitting to HN

- See your "HN worthiness" score

I built this because I noticed many posts get flagged (including mine) or fail to gain traction simply due to formatting issues or guideline violations. This tool aims to help writers optimize their content before submission.

The analysis covers both official HN guidelines and common community preferences. It's particularly helpful for technical writers who want to maximize their posts' visibility.
