Frequently asked questions
Is this really free?+
Yes — a handful of free generations per day, no account or credit card required. It's a preview of the AI that powers Orbin's full platform.
How many hashtags do I get?+
Around 8 per generation, tailored to what tends to work best on the platform you pick — for example, fewer and punchier for X/Twitter, a broader mix for Instagram.
What's the difference between this and Orbin?+
This tool suggests hashtags on demand. Orbin generates full posts and hashtags together in your brand voice, schedules them across your connected networks from one calendar, and predicts engagement before you post.
Which platforms are supported?+
Facebook, Instagram, X, LinkedIn, Pinterest, TikTok, YouTube, and Threads — pick one and the hashtags are tailored to that platform's conventions. Orbin itself publishes to Facebook, Instagram, X, and LinkedIn; Pinterest, TikTok, YouTube, and Threads publishing is coming soon.
Do you store what I type?+
Your prompt is sent to Claude to generate hashtags and isn't tied to an account, since you're not signed in. See our Privacy Policy for details.
