PostMine

What it does

PostMine is a growth copilot for solo founders. It studies your product by reading your website and then provides a feed of live conversations on X, Reddit, Hacker News, and Threads where your product belongs. It also drafts ready-to-publish posts in your voice for multiple platforms. Everything refreshes twice a day (morning and evening).

PostMine goes beyond simple posting: it generates strategy docs, SEO and GEO audits, competitor dossiers, and a brand voice guide. It also offers a reply-opportunity finder that surfaces threads where people ask for or discuss what you build, with a drafted reply you can review and post manually.

Who it is for

PostMine is designed for solo founders and small teams who need to maintain a consistent social media presence but lack time or resources. It targets founders who are deep in code and struggle to show up daily on social platforms. The tool is especially relevant for SaaS builders who want to engage in niche communities without spending hours each day.

Why it matters

Consistent posting is critical for growth, but it's time-consuming. PostMine automates the research and drafting process, reducing daily effort to about 15 minutes. By finding conversations where your product is relevant and preparing posts in your voice, it helps founders maintain visibility and engage with potential customers without the grind. The twice-daily refresh ensures content stays timely.

Launch signal

PostMine is currently live with a free plan and a Pro plan at $49/month. It supports posting to X, Dev.to, LinkedIn, Telegram, and Threads (with pre-filled composer). Reply opportunities are found on X, Reddit, Hacker News, and Threads. The product also offers an MCP server for AI assistant integration (Pro feature). Bluesky is planned next.

Brand and naming

PostMine is a descriptive name that clearly conveys the core function: mining conversations for posting opportunities. It is memorable and domain-friendly (postmine.tech). The tagline and summary position it well as a growth copilot for solo founders, emphasizing automation and daily engagement. However, the name may be slightly generic and could be confused with other 'post' tools. Overall, it's effective for its niche.
