Yes! With a PRO subscription, our AI voice training feature lets you provide sample tweets that represent your style. The more examples you add, the better the AI understands your unique voice—whether that's professional, witty, provocative, or anything in between.

Free users post via X Web Intent—a new tab opens on X with your tweet pre-filled, and you hit Post yourself. PRO users can auto-post directly through the X API, but you always review and approve content before it goes live.

For free users, we only need basic login. Posting happens through X Web Intent (opens X in a new tab), so we never post on your behalf. PRO users grant write access for auto-posting and scheduling—but only when you explicitly approve each post. We never access your DMs or follow/unfollow accounts.

Yes, cancel anytime from your account settings. You'll keep access until the end of your billing period. No questions asked, no cancellation fees.

Security is our top priority. We use bank-level encryption, never store your X password, and comply with industry-standard security practices. Your data is never sold to third parties.

BirdlyHQ gives you a library of viral-ready tweets you can post instantly—no writing required. Upgrade to PRO for AI-powered replies trained on YOUR voice, auto-posting, and scheduling. We help you create and engage, not just schedule.
