JustPDF vs Postmine

No account needed for the free tier (3 ops/day). Pro starts at $4/month for unlimited access. FERPA-compliant for educational use.

Postmine is your all-in-one content creation engine that turns viral social media discussions into a full week's worth of content in under 30 seconds. It starts with a simple Chrome Extension that lets you right-click any trending post on LinkedIn, Reddit, Facebook, or X (Twitter) and capture it instantly. The magic happens when Postmine's AI transforms that single discussion into seven different, platform-ready pieces: a blog post, a LinkedIn article, a Twitter thread, a Facebook post, an Instagram caption, a Reddit post, and an FAQ. No more staring at a blank page. It's built for anyone who spots a great conversation online and thinks, "This would make an amazing post," but doesn't have hours to write and adapt it. Content creators, social media managers, marketing teams, solopreneurs, and freelance writers can all save over 5 hours per week. With features like Brand Voice Profiles to keep your content authentic, a built-in Content Calendar for scheduling, and the flexibility to use your own AI API key, Postmine gives you complete control from capture to publication.
