Ghosti X

Setting up your Twitter AI agent takes about five minutes. Install the Ghosti Chrome extension, open the sidebar on X, and run the quick onboarding — pick your personality, tone, and writing style, or add a few creators as voice inspiration. Drop in your own API key from Gemini, OpenAI, Anthropic, or OpenRouter and you're live. From then on Ghosti drafts posts, replies, and threads in your voice right inside the X compose box. You just review and hit Post — no prompting, no copy-pasting, and no Twitter login required.

A Twitter (X) AI agent is software that helps you create content on X — drafting tweets, replies, and threads, suggesting takes, and keeping you posting consistently without doing it all by hand. Ghosti is a draft-first Twitter AI agent: it lives inside the X compose box, learns your voice, and writes in your style on demand. The key difference from autopilot bots is that Ghosti never auto-posts or touches your account — you stay in control and click Post yourself.

The best Twitter AI agent comes down to what you need, but if you want drafts that actually sound like you instead of generic AI slop, Ghosti is built for exactly that. It runs as a Chrome extension directly inside X, trains on your voice, supports Gemini, GPT, Claude, and OpenRouter through your own keys, and never auto-posts. Unlike standalone chatbots or auto-tweet bots, Ghosti keeps you in your workflow and in control of every post.

Yes — Ghosti drafts a reply for any tweet on your timeline in one click, written in your voice and tuned to the conversation. The difference is that it drafts, it doesn't auto-send. You see the reply, tweak it if you want, and post it yourself. That keeps your replies authentic and your account safe, instead of spraying out auto-generated responses.

Some do — and that's exactly what gets accounts flagged. Ghosti deliberately doesn't. It's a draft-only Twitter AI agent: it writes the post, reply, or thread for you inside X, but you always click Post yourself. Nothing is automated against Twitter's UI, so there's nothing for X to detect. You get the speed of an AI agent without the risk of an auto-poster.

Build-in-public is exactly where Ghosti shines. Shipping daily progress updates, launch threads, and milestone posts takes a level of consistency most founders can't keep up by hand. Ghosti drafts your #buildinpublic updates, progress threads, and changelog posts in your voice, right inside X — so you keep your audience in the loop without burning an hour a day writing. Indie hackers and build-in-public founders are our core users, and Ghosti is tuned for the ship-daily, post-in-your-voice workflow.

For the BYOK (Bring Your Own Keys) plans — yes, you plug in your own API key from Gemini, OpenAI, Anthropic, or OpenRouter. You pay your AI provider directly, so Ghosti access stays simple and there are no managed token limits.

Twitter / X is fully supported right now. Reddit and LinkedIn support are coming soon.

Yes! During onboarding you set your personality, writing style, and tone. Ghosti learns how you write and generates drafts that sound like you — not like a robot. You can fine-tune this anytime in the sidebar settings. Don't have a voice yet? You can add multiple creators as voice inspiration and Ghosti will blend them into a unique hybrid style that's all yours.

Roughly ~$5/month for around 1,000 generations on most providers. Actual cost depends on the model you pick and how much you use it. Flash models are best for cost and speed, premium models give you higher quality output — you choose what fits your workflow.
