Caption questions
Is this caption generator really free?+
Yes — it runs entirely in your browser. No sign-up, no credits, no limit. It exists so your finished video ships with a caption that fits the scene.
Do the captions work without a video?+
They are written for AI rap videos — they reference the verse, the stage and the sound. Pair one with your clip from the studio for the full post.
Can I edit the captions after copying?+
Please do. The generator gives you a starting point — swapping in a name, an inside joke or a date makes any caption hit harder.
