Frequently asked questions

Is this really free?

Yes. 3 caption generations per day, no signup, no card. If you need more, AuTime gives unlimited captions plus auto-upload to TikTok.

How does the AI know what works on TikTok?

The model is prompted with proven hook structures, niche-specific patterns and engagement-driving CTAs derived from real TikTok performance data.

Can I use these captions commercially?

Yes, freely. You own everything you generate. Edit and adapt them to your voice.

How are these different from ChatGPT?

ChatGPT is generic. This tool is tuned specifically for TikTok structure (hook + body + CTA + hashtags), with niche-aware patterns and the right length for TikTok captions.

What other free tools do you have?

We also have free hashtag lists by niche — check tiktok-hashtags. More tools coming soon.
