Yes, completely free with no sign-up. Create branded TikTok challenges with rules and hashtags instantly. Free users have a daily limit; Pro users get unlimited access.

Enter your brand or campaign name, target audience, and the action you want participants to perform. The AI generates a complete challenge brief including the challenge name, hashtag, participation rules, a branded sound recommendation, and a launch strategy to get the first 100 participants.

Viral challenges are: physically achievable by anyone, visually interesting to watch even without context, repeatable with personal variations, and have a clear participation mechanic (tag 3 friends, use this sound, show your version). Challenges that require special skills or expensive products rarely spread. This generator designs challenges around these viral principles.

Brands use hashtag challenges to generate user-created content at scale — effectively getting thousands of free ads. The key is making the challenge fun first and branded second. The hashtag carries the brand name but the content should feel like play, not promotion. This tool builds challenges that feel organic even when brand-led.
