Postmine

Postmine is your mobile-first content creation engine, designed to transform the way you find and produce content. It eliminates the blank page by turning a single viral social media discussion into a full week's worth of platform-ready posts in under 30 seconds. The process starts with a seamless Chrome Extension that lives in your browser. When you spot a trending thread on LinkedIn, Reddit, Facebook, or X (Twitter), you simply right-click and capture it. Postmine's AI then works its magic, expanding that one discussion into seven distinct content pieces: a blog post, a LinkedIn article, a Twitter thread, a Facebook post, an Instagram caption, a Reddit post, and an FAQ. Built for content creators, social media managers, marketing teams, solopreneurs, and freelance writers, Postmine saves over 5 hours per week. It puts you in complete control with Brand Voice Profiles for authentic content, a built-in Content Calendar for scheduling, and the flexibility to use your own AI API key. From the initial capture to final publication, Postmine is the all-in-one system that helps you own your content strategy directly from your workflow.

7-Format AI Content Generation

Postmine's core AI engine transforms one captured social media post into seven different, optimized content pieces. It automatically generates a full blog post, a LinkedIn article, a Twitter thread, a Facebook post, an Instagram caption with hashtags, a Reddit post, and an FAQ document. You can use the included Postmine AI or bring your own API key for models like Claude, OpenAI, Gemini, or DeepSeek, ensuring flexibility and control over the generation quality and cost.

Brand Voice Profiles

This feature ensures every piece of content sounds authentically like you or your brand. You can set your preferred tone, define your target audience, list key phrases to include, and specify terms to avoid. Once configured, Postmine's AI applies these parameters consistently across all generated content, moving beyond generic AI output to deliver material that truly resonates with your unique voice and audience.

One-Click Chrome Extension

The Postmine Chrome Extension is designed for effortless capture without disrupting your browsing flow. Installed in your browser, it allows you to right-click any social media post on supported platforms and select "Generate Content Pack" from the context menu. A sleek side panel then displays your generated content right on the same page, eliminating the need to switch tabs or apps and keeping you in your creative zone.

Built-in Content Calendar

Organize and schedule your content strategy directly within Postmine. The integrated Content Calendar provides a week or month view where you can drag, drop, and schedule your generated content pieces. It helps you visualize your posting pipeline, see what's coming up, track what's overdue, and mark items as published, ensuring you never miss a critical posting window.

For Social Media Managers

Social media managers can use Postmine to drastically reduce the time spent on content ideation and creation. By capturing trending discussions relevant to their brand, they can instantly generate a week's worth of varied content for all major platforms. The content calendar and scheduling features allow for seamless planning and consistent posting, freeing up hours for community engagement and strategy.

For Solopreneurs and Personal Brands

Solopreneurs wearing multiple hats can leverage Postmine to maintain a consistent and professional online presence without the time investment. Spotting an engaging discussion in their niche, they can right-click to capture it and quickly generate authentic content in their own voice. This enables them to stay active and relevant across blogs and social media, driving growth while focusing on their core business.

For Marketing and Content Teams

Marketing teams can use Postmine to scale content production efficiently. The Bulk Capture Mode allows them to process multiple trending posts from a feed in one session, batch-generating numerous content packs for weekly planning. This streamlines the workflow, ensures a steady content pipeline, and aligns all output with the company's established brand voice guidelines.

For Freelance Writers and Agencies

Freelance writers and content agencies can use Postmine to rapidly research and create first drafts for clients. By capturing viral threads, they gain immediate insight into current audience interests and pain points. The AI then provides a strong, multi-format foundation that writers can quickly refine and personalize, significantly speeding up project turnaround times and increasing client capacity.

Postmine offers simple, transparent pricing to fit different content needs. The $1 Trial provides full Starter plan access for 7 days, converting to $49/month thereafter, and includes 10 content packs per month with all features. For short-term projects, the 10-Day Pass is a one-time $10 fee for 50 content packs over 10 days with no subscription.

How does the Postmine Chrome Extension work?

The Postmine Chrome Extension adds a new option to your browser's right-click context menu on supported social media sites like LinkedIn, Reddit, and X. When you see a post you want to turn into content, simply right-click on it and select "Generate Content Pack." The extension captures the post's text and sends it to Postmine's AI, which then creates your content pack, often displayed in a side panel on the same page for immediate review.

Can I use my own AI API key with Postmine?

Yes, Postmine offers full flexibility. You can choose to use the built-in Postmine AI, which requires no additional setup. Alternatively, if you prefer a specific model or want to manage costs, you can bring your own API key from providers like OpenAI, Anthropic (Claude), Google (Gemini), or DeepSeek. This gives you complete control over the AI engine powering your content generation.

What is included in a single "Content Pack"?

Each Content Pack generated by Postmine includes seven different platform-optimized pieces of content derived from the one post you captured. This pack consistently contains a comprehensive blog post, a LinkedIn article, a Twitter/X thread, a Facebook post, an Instagram caption complete with relevant hashtags, a Reddit post, and a helpful FAQ document. It's designed to fully leverage one idea across your entire content ecosystem.

What happens after my $1 trial ends?

The $1 trial gives you full access to the Starter plan features for 7 days. If you do not cancel before the trial period ends, your subscription will automatically convert to the ongoing Starter plan at $49 per month. You can cancel at any time during the trial from your account settings to avoid being charged, making it a risk-free way to test the platform's capabilities.
