What to write in a TikTok caption
Write a TikTok caption that adds context, drives comments, and works with the algorithm. Fill in your details below, copy the prompt, and paste it into ChatGPT, Claude, or Gemini.
TikTok captions that just re-state what's in the video: "Watch me try this recipe" under a cooking video, add no value and generate no engagement beyond what the video itself earns. The caption is a secondary but meaningful opportunity to drive comments and reach, and most creators leave it underused.
A TikTok caption that adds to the video rather than repeating it asks a question that makes viewers want to comment, adds context the video doesn't provide, or hooks the viewer into watching the whole thing. Three to five relevant hashtags help with discovery. Short and punchy with a clear call beats long and descriptive.
Enter what your video is about, your audience, what you want viewers to do, and the tone. The AI gives you three caption options that add value to the video and are built to drive the specific action you want.

Help me write a TikTok caption.

Give me 3 options.

Tips for writing this
- 1The caption on TikTok is secondary to the video hook, but a question in the caption drives comments, which boost reach.
- 2Do not just describe the video in the caption. Add context or a question that makes them engage.
- 3Use 3 to 5 hashtags. More than that looks spammy and does not help.
Common questions
How long should a TikTok caption be?+
Under 150 characters for the visible part before it gets cut off. Keep it punchy. Use the caption to ask a question or add something that the video does not say on its own.
How do I use this prompt?+
Fill in your details using the form above. The placeholders in the prompt update live as you type. When you are ready, click “Copy prompt” and paste it into ChatGPT, Claude, Gemini, or any AI tool. The AI will write something personalized to your specific situation.
Which AI tool works best for this?+
Claude and ChatGPT both work well. Claude tends to produce more natural, nuanced writing for personal situations. ChatGPT is strong for structured business and professional writing. Try both and keep the version that sounds more like you.
Should I use the AI output word for word?+
Use it as a strong first draft, then edit it to sound like you. The AI gives you the structure and language to work from. Reading it out loud is one of the best ways to catch anything that does not feel natural in your voice.
