Threads Caption Generator
Type what your post is about, choose a tone, add a call to action, and copy a caption that's ready for Threads.
What makes a good Threads caption
Posts are capped at 500 characters.
- Lead with the hook. The first line decides whether anyone taps "more".
- Say one thing. A caption that tries to cover everything says nothing.
- Ask for one action: save, share, comment or follow. Not all four.
- Write the keyword people would search for, in plain text.
Use the caption as your script's opening line
The best captions and the best video hooks are often the same sentence. Try saying your caption out loud as the first line of the video, then build the rest with our script generators and read it on the live teleprompter.
Read your script hands-free on iPhone, iPad and Mac. The teleprompter follows your voice.
