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!"
