A growth copilot for solo founders: it finds the conversations your product belongs in and keeps ready posts stocked in your voice, twice a day. 15 minutes, every day.
Just build your dream project. We run the growth:
we study your site, write your strategy docs, audit your SEO and GEO, find where your customers already are, and post in your voice, one click to go live!
How it works
One URL, zero setup
Paste your project link and PostMine reads all of it: your site, your product, your niche and the way you write. Everything starts from your reality, not a blank page.
A growth team's output in minutes
Strategy docs, an SEO and GEO audit, a competitor dossier and a live feed of conversations worth joining across X, Reddit, Hacker News and Threads. Every draft comes back in your own voice, not generic filler.
Publish without leaving the tab
Send posts to X, Dev.to, LinkedIn and Telegram in one click, and Threads opens with a pre-filled composer. Publish now or schedule ahead, all from one place. No copy-paste, no tool-hopping.

Questions, answered
Everything founders usually ask before pasting their URL. Anything else: write to us.
No. PostMine reads your whole project first: it studies your site, writes your Product Information, Customer Research and Marketing Strategy docs, audits your SEO and GEO, builds a competitor dossier, and finds live conversations where your customers already are. Posting in your voice is the last step, not the whole product.
Yes. Free keeps three ready posts stocked for X, Dev.to and Threads, and holds a live reply-opportunity inventory across X, Reddit, Hacker News and Threads, topped up twice a day, morning and evening: up to 2 active threads on X and 5 per community source, 17 in total. Unanswered threads rotate out after 48 hours, untouched drafts after 7 days, so the shelf stays fresh. Pro is $49/mo and keeps six ready posts stocked for every platform, holds twice as many active opportunities (up to 34 versus 17), winner-mining and the premium docs.
For posting, X, Dev.to, LinkedIn, Telegram and Threads are live today; Threads posts open pre-filled in your own Threads composer, so you publish in one click from your own account, no connection. For finding reply opportunities, X, Reddit, Hacker News and Threads are all live: PostMine finds threads where your customers ask for what you build and drafts a reply you post yourself. Bluesky is planned next.
PostMine finds public threads on Reddit, Hacker News and Threads where people ask for or discuss what you build, drafts a reply in your voice, and shows the source, the thread and its public counts (Reddit upvotes, Hacker News points and comments, or Threads likes and replies) so you can size it up before replying. You post it yourself: open the thread and paste your reply from your own account. There is no Reddit, Hacker News or Threads connection and we never post for you, so keep to each community's rules. These opportunities are on every plan; Pro simply holds twice as many of them active at once.
PostMine builds a tone profile from your connected accounts in one click, then writes every draft in it. You can switch presets or edit by hand, and you approve each post before it publishes.
Never. AI drafts the variants; you edit and approve each one. Nothing leaves PostMine until you hit Post or the time you scheduled.
No. Start free with no card. Pro asks for a card when you upgrade, and you can cancel anytime in one click.
Yes. PostMine ships an MCP server: connect it to Claude, Cursor or any MCP-capable assistant and it can draft and publish posts through your account. You stay in charge: it publishes only what you tell it to, the same rule as in the app. MCP access is part of Pro.
Connected-account credentials are stored encrypted at rest (AES-256-GCM); platforms connect via OAuth, so we never see your passwords, and you can disconnect any platform at any time. Your text goes to AI providers only to generate your docs and drafts. The full list of what we store and every processor we use is on the Privacy page.
