PostMine is a browser-based X (Twitter) growth workspace that gathers saved posts, replies, idea sources, lead-finding search and post scheduling into a single app with AI-assisted drafting.
What is PostMine? PostMine is a web app for growing an X account, organised around five connected areas: Bookmarks, Replies, Inspirations, Find leads, and Calendar. You sign in with X, add your topics and a few words about yourself, then draft posts and replies from saved posts, your own ideas or conversations you discover — every draft is refined in chat before you choose when to publish or schedule it. It runs in a browser on desktop and mobile, and the product pages state that you do not need a website or a finished product to start.
Key Features
- Bookmarks — keep useful X posts in one place and return to them when you need an idea for something new to write.
- Replies inbox — see replies to your posts in one inbox and draft a response without leaving the conversation view.
- Inspirations — browse posts and formats worth learning from, with a "Use" action on sample cards that turns an admired topic into a post of your own.
- Find leads — search X, Reddit, Hacker News and Threads for people describing problems you solve, read the thread and write a relevant reply.
- Calendar — plan and schedule posts and see what is going out and when in one view.
- AI credits — a single credit balance covers drafts, regenerations and AI edits; manual edits and publishing consume no credits.
- Public account audit — enter any public X handle and up to 40 of its latest public posts are reviewed with a verdict per post plus an overall score; the page notes a verdict is an automated opinion, not proof of AI authorship.
- Voice controls — your ideas, past posts and preferred tone guide the draft, which you can edit before publishing.
Who is it for? Creators building an audience on X: keep a bookmark library, pull inspiration from posts they admire, and schedule a steady posting cadence instead of writing everything on the day.
Founders and indie builders sharing product updates: draft small update posts from bookmarks and screenshots, and reply to people who respond to them.
Freelancers and consultants looking for clients: use Find leads across X, Reddit, Hacker News and Threads to locate conversations about problems they solve, then reply with context.
Experts and writers without a product or website: sign in with X, list topics and a short self-description, and start from an idea, a saved post or a conversation.
What can you do with PostMine?
- Solo creators with a backlog of bookmarks: turn saved posts into drafts in the Inspirations and Bookmarks areas so saved material actually becomes published posts.
- Freelancers prospecting: run Find leads to surface people describing relevant problems, read the conversation, and send a reply that fits the thread.
- Founders replying to their audience: work through the Replies inbox, draft responses in the same view, and keep replying after a small update post.
- Anyone curating a low-volume feed: plan and schedule posts in the Calendar so publishing happens on a rhythm rather than in bursts.
How does PostMine work?
- Sign in with X and add your topics plus a few words about yourself — a website is optional.
- Collect inputs: save posts to Bookmarks, browse Inspirations, or find relevant conversations with Find leads.
- Generate a draft with AI credits, refine it in chat using your own posts and preferred tone, then review it.
- Publish or schedule the post yourself from the Calendar; nothing goes out without your approval.
Pricing PostMine uses a freemium model with two plans. Free costs $0/mo and is described as a free plan rather than a trial: it includes 200 AI credits once, one initial search with Find leads across X, Reddit, Hacker News and Threads, creating posts from bookmarks, replying to replies, finding inspiration and calendar scheduling. Pro is listed at $29/mo, shown against a $49 comparison and described as a limited founding offer with 9 seats left and the price locked while subscribed; it adds 3,000 AI credits every subscription month and Find leads that refreshes every 24 hours after use, plus everything in Free. Billing is offered monthly or yearly, with a 20% discount on the yearly option.
FAQ Is PostMine free to try? Yes. The Free plan costs $0/mo and the site describes it as a free plan rather than a trial. It includes 200 AI credits issued once, one initial Find leads search, bookmark-based post creation, the Replies inbox, Inspirations and Calendar scheduling. Pro adds 3,000 AI credits per subscription month and a Find leads search that refreshes every 24 hours after use.
Do I need a website or a product to start? No. PostMine says a website is optional: you sign in with X, add your topics and a few words about yourself, and can begin from your own idea, a saved post or a conversation. The product's own account states you can start with your X posts and your voice even without a product or website.
Does PostMine publish anything without my approval? No. Drafts are generated for you to review and edit, and you decide when to publish or schedule each one. Manual edits and publishing do not use AI credits — credits are spent on drafts, regenerations and AI edits.
Can I use PostMine on my phone? Yes. PostMine opens in a browser on mobile and desktop, so posts and conversations can be worked on wherever you are rather than only at a desk.
What is the public account audit? The audit takes any public X handle and reviews up to 40 of its latest public posts, returning a verdict for each post and an overall score. It is free for everyone, and the page notes a verdict is an automated opinion, not proof of AI authorship.
