LinkPersona – Free LinkedIn audit tool that runs 100% in the browser

Hacker News

"Hi HN, I built this because I was frustrated that every "LinkedIn Optimizer" requires OAuth access or a PDF upload. I didn't want to send my personal data to a third-party server just to check my headline structure. LinkPersona is a static site (HTML/Tailwind/JS). All the analysis logic (regex for checking 'Role + Result + Metric' patterns, readability scores, etc.) happens client-side. No databases, no tracking pixels, no signup. It includes: Headline analyzer Hook previewer (simulating the mobile vs desktop truncation point) Post formatter Code is not minified if you want to poke around 'view source'. Feedback welcome!"
