About Sleeping Bird

You know what you want to say. You just don't always have the time (or energy) to say it well. Sleeping Bird doesn't write replies for you. It takes your rough idea — a few words, a half-formed thought — and turns it into 3 polished variations that keep your voice, your opinion, and your intent intact. You pick the one that fits, copy it, and post. No ghostwriting. No generic AI slop. Just your ideas, sharpened. How it works: You're on X, about to reply to a tweet. Click the ✨ icon in the compose toolbar. Type your draft — even a messy one-liner is fine. Sleeping Bird gives you 3 variations. Click the one you like, it's copied to your clipboard. Done. Why people use it: • You reply a lot and want to move faster without sounding rushed • English isn't your first language and you want your replies to land right • You have the ideas but struggle to phrase them clearly • You want to grow on X by engaging more, without sacrificing quality What it's not: • It's not a bot. It doesn't post for you. • It's not generating opinions. The ideas are yours. • It's not collecting your data. Everything runs client-side with your own Grok API key. No servers, no tracking, nothing leaves your browser. Privacy first: Your API key is stored locally in your browser. Sleeping Bird has zero backend — no analytics, no accounts, no data collection. Period. Requires a Grok API key from console.x.ai (free tier available).
