Frequently Asked Questions

XposterAI is a scheduler and AI engagement toolkit for X (formerly Twitter). It does four things: schedules and auto-publishes your posts from a queue, generates AI-powered replies and quotes in your own voice via the Chrome extension, gives you 50 free creator tools (character counters, thread splitters, hashtag generators, and more), and lets you train a Persona that teaches the AI how you write so nothing you publish sounds like a bot.

Premium's list price is $19.99/month ($199.99/year). While the founding member offer runs, every new subscription gets 50% off automatically at checkout — $9.99/month or $99.99/year — and that rate is locked in for as long as your subscription stays active, even after the offer ends for new customers. No code needed; the discount is applied for you.

No. Whatever rate you subscribe at is yours for as long as your subscription stays active — price increases only ever apply to new customers. Subscribers from before this pricing simply keep their original rate; founding members keep $9.99/month after the founder window closes. If you cancel and later resubscribe, the then-current pricing applies.

Connect your X account from the dashboard, compose posts, and either publish immediately or queue them for a future date and time — XposterAI publishes them automatically, even when your browser is closed. Premium includes 100 post credits per month, separate from your reply credits. A regular post uses 1 credit; posts containing a link use 13 (links cost significantly more to publish through the X API). Scheduled posts are only charged when they're actually published, and you can cancel anything in the queue before it goes out.

Persona Studio is where you train XposterAI on a handful of your own past tweets — 5 to 10 is usually enough. The AI generates a voice summary describing your tone, cadence, and vocabulary, which you can edit. From then on, AI replies generated from the extension mirror that voice. You can save multiple personas and switch between them per account or per topic.

The Chrome Extension for XposterAI seamlessly integrates with your browser, providing quick access to our AI-powered reply generation features directly on Twitter. This means you can use our service without ever leaving your social media workflow, making your social media engagement more efficient and effective.

Our AI is trained on a vast dataset of social media interactions, enabling it to understand context, mood, and the subtleties of human language. This allows Xposter to generate replies that are not only relevant and engaging but also appropriately match the tone and style of the original message.

Absolutely! We offer a free trial that includes a limited number of reply credits, giving you a firsthand experience of how XposterAI can transform your social media engagement. No credit card is required to start your trial, and you can upgrade to a premium plan at any time.

No. Every tool at /tools/ — character counters, hashtag generators, the engagement rate calculator, the QR code generator, and the rest — works without an account, no credit card, no signup. A handful of AI-backed tools (the reply generator, reply audit, tone rewriter, hashtag generator, and similar) are capped at 3 free uses per day per browser. The non-AI tools are unlimited.

Reply credits are how we measure usage on XposterAI. Each time you generate a reply using our AI, one credit is consumed. Different subscription plans offer a varying number of reply credits per month, catering to the needs of individual users and businesses alike. This ensures that you only pay for what you need.

Free forever: the 50 creator tools, the Extract Link feature, and 30 one-time reply credits to try the extension. The Premium plan unlocks the Scheduler (100 post credits per month), 3,000 reply credits per month, and priority email support. Persona Studio is included on every plan, free included.

Yes, once you've trained at least one Persona. If you've saved multiple, you can pick the active one from inside the Chrome extension. Without a trained Persona, the extension falls back to the tone you select (witty, professional, sarcastic, etc.). Training a Persona is what makes replies sound like you specifically rather than generically "AI."

Getting started is simple! Just sign up on our website, choose your preferred subscription plan, and you're ready to enhance your social media presence. Download the Chrome Extension from the Chrome Web Store and use registered email to link it to your XposterAI account for an integrated experience.

When you click the extract icon under a tweet, XposterAI scans the tweet’s content to locate any embedded media, hyperlinks, or referenced content. It then pulls out the source URL and displays it for you, allowing easy reposting with your own caption. This feature does not rely on reply credits. It is a complimentary feature included with all accounts and can be used unlimited times.

Credits reset monthly on every paid plan. Credits don't roll over — any unused credits are cleared at the end of the cycle. This keeps things simple and fair for everyone.

Your training tweets and voice summary live in your XposterAI account. They're sent to the AI provider only when you generate a reply that uses that Persona, and aren't used to train the AI provider's models. You can edit your voice summary or delete any Persona at any time from /dashboard/persona.
