Create Viral TikTok Captions That Get Views
TikTok captions are your video's hook. Our AI helps you craft captions that stop the scroll, complement your video, and drive engagement—helping your content reach TikTok's algorithm and go viral.
Hook Viewers in the First Line
TikTok shows only the first line of your caption in the feed. Our AI creates hooks that make people stop scrolling and watch. A great caption can be the difference between 100 views and 100K views.
Optimize for TikTok's Algorithm
TikTok's algorithm looks for engagement signals. Our AI helps you write captions that encourage comments, shares, and saves—the three things that tell TikTok your content is valuable and should be shown to more people.
Post More, Stress Less
TikTok rewards consistency. Posting daily (or multiple times daily) helps your content reach more people. Our AI generates captions in seconds, so you can focus on creating videos instead of writing captions.

TikTok trends move fast. Our AI helps you create captions that work with trending sounds, hashtags, and formats. Get caption drafts instantly so you can jump on trends while they're still hot.

Try GenSumo FreeHow to Write TikTok Captions That Go Viral
TikTok's algorithm is all about engagement in the first few seconds. Here's how to write captions that stop the scroll, complement your video, and drive the comments, shares, and saves that make TikTok push your content to more people.
- Hook Them in the First 3 Words
TikTok only shows the first line of your caption in the feed. Make it count. Start with something that makes people stop scrolling: a question, a bold claim, or something intriguing. The first 3 words determine if they'll watch.
- Complement Your Video, Don't Repeat It
Your caption should add context your video doesn't show. If your video is a tutorial, use the caption to explain the problem it solves. If it's funny, use the caption to set up the punchline. Add value, don't just describe.
- Ask Questions That Get Comments
End with questions that are easy to answer. "Have you tried this?" or "What would you do?" gets more comments than generic questions. Comments within the first hour boost your video's reach significantly.
- Use Trending Hashtags Strategically
Include 3-5 trending hashtags relevant to your content, plus 2-3 niche hashtags. Our AI can include hashtags when you toggle them on. Mix popular and niche tags to reach both broad and targeted audiences.
- Create Urgency or FOMO
Phrases like "POV: you just discovered..." or "Wait until the end..." make people want to watch the full video. Our AI helps you craft hooks that create curiosity and keep viewers watching.
- Post During Peak Hours
TikTok engagement peaks at different times for different audiences. Generally, 6-10am and 7-9pm work well. Post during these windows with a caption designed to get quick engagement. Early comments and shares boost reach.
- Edit for Your Voice
Our AI gives you a solid starting point, but add your personality. Include inside jokes, reference your niche, or add details only your audience gets. Authentic captions that match your video's energy perform best.
