What is Postmine?

Postmine is a Chrome Extension that captures trending social media posts from LinkedIn, Reddit, Facebook, and X with a single right-click. Its built-in AI then transforms each captured post into seven platform-ready content pieces—blog posts, LinkedIn articles, Twitter threads, Facebook posts, Instagram captions, Reddit posts, and FAQs. The tool also includes a content calendar for scheduling and publishing directly from the dashboard.

Who it's for

• Content creators who want to turn viral social discussions into a week's worth of polished posts without starting from scratch
• Social media managers juggling multiple platforms who need to repurpose trending conversations into platform-optimized content quickly
• Solo entrepreneurs and freelancers who lack time for manual content creation but still want a consistent, branded presence across channels

Key features

AI Content Generation

One social media post becomes seven platform-optimized pieces. You can use Postmine's built-in AI or bring your own API key from Claude, OpenAI, Gemini, or DeepSeek for more control over the output.

Chrome Extension with Bulk Capture

Right-click any social media post to capture it instantly—a side panel shows generated content right on the page. Bulk mode lets you select multiple posts from your feed and batch-generate content packs for all of them at once.

Brand Voice Profiles

Set your tone, target audience, key phrases, and terms to avoid. Every piece of content is generated in your unique brand voice, eliminating generic AI output.

Content Calendar and AI Reply Suggestions

Schedule generated content directly to a week or month calendar view, mark items as posted, and see what's coming up. The AI also provides five crafted reply suggestions for any post to help you engage faster.

What stands out

"One capture becomes a week's worth of posts."

Postmine eliminates the repetitive cycle of manually rewriting the same idea for different platforms. Instead of spending hours adapting a single trending post into separate formats, you right-click once and get seven distinct, platform-optimized pieces—complete with relevance scoring so you know which discussions are worth your time. The combination of instant capture, brand voice consistency, and built-in scheduling makes it a complete content production system rather than just a generation tool.

Worth checking out if…

You regularly find yourself scrolling through LinkedIn, Reddit, or X and thinking "I could turn this into a blog post" but never have the time. Postmine is especially useful if you manage multiple social accounts and want a single workflow that goes from spotting a trending discussion to publishing across all platforms without tab-switching or manual reformatting.
