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.
What's the difference between this and Orbin?+
This tool writes a single caption on demand. Orbin adds your brand voice, generates and schedules content across every network from one calendar, predicts engagement before you post, and can even run on autopilot.
Which platforms are supported?+
Facebook, Instagram, X (Twitter), LinkedIn, TikTok, YouTube, Pinterest, and Threads — pick one and the caption is tailored to that platform's style and length conventions.
Do you store what I type?+
Your prompt is sent to Claude to generate a caption and isn't tied to an account, since you're not signed in. See our Privacy Policy for details.
