Auto Caption Generator — No Typing
Skip manual captioning. Our auto caption generator reads your script and builds a caption video at normal speaking pace (150 WPM). You get a styled caption layer in MP4 format. Overlay it on your clip to add subtitles to video in one step instead of using a Capcut caption generator or similar tool line-by-line.

Why Use This Caption Generator to Add Subtitles to Video?
How to Generate Captions on TikTok and Beyond
If you’ve wondered how to generate captions on TikTok or other apps, this tool gives you a caption video in seconds. Paste your script, choose a style (full phrase or word-by-word highlight), and download MP4. Use it as a TikTok caption generator by adding the file as a layer in CapCut or TikTok — no need to type captions manually. The same workflow works as a YouTube caption generator style overlay or Facebook caption generator for Reels.
Snapchat & Instagram Caption Generator
A Snapchat caption generator or Instagram caption generator that outputs video is rare — most only suggest text. Here you get an actual caption video file. Use it in Stories, Reels, or feed posts to add subtitles to video with consistent timing and style. Great for accessibility and engagement.
Add Subtitles to Video Without an AI Caption Generator
You don’t need an AI caption generator or speech recognition to add subtitles to video. Type or paste your script and our caption generator creates the visuals. Ideal when you already have a script, when you’re dubbing, or when you want full control over wording. The result is a caption video you can drop into any editor.
CapCut Caption Generator Alternative
If you use a Capcut caption generator for word-by-word captions, you can speed up workflow by generating the caption layer here first. Get green-screen or dark-background MP4, then composite in CapCut. You keep CapCut’s editing power while getting a fast caption video from a single script paste.

Frequently Asked Questions
Common questions about the caption generator, auto caption generator, how to add subtitles to video, and using the tool as an Instagram or TikTok caption generator.
Q:Is this caption generator free?
Yes. Our auto caption generator is free. No sign-up, no watermarks. Create as many caption videos as you need and add subtitles to video for TikTok, Instagram, YouTube, or any platform.
Q:How do I use this as a TikTok caption generator or Instagram caption generator?
Generate your caption video here, then import the MP4 into TikTok, CapCut, or your editor. Place it over your clip to add subtitles to video. It works like a pre-made caption layer — no need to type captions line-by-line. Same idea for an Instagram caption generator or Facebook caption generator.
Q:How do I add subtitles to video with this tool?
Paste your script and generate. You get an MP4 with captions on a green screen or dark background. Add that file as a layer in your video editor on top of your footage. Use chroma key on the green style or blend the dark style to add subtitles to video with minimal effort.
Q:Can I use this as a YouTube caption generator?
This tool creates a visual caption video (on-screen text), not an SRT file. You can use that video as an overlay in YouTube videos for styled captions. For standard YouTube subtitles (SRT/VTT), use YouTube Studio. For a YouTube caption generator that gives you a ready-made caption layer, this tool fits the bill.
Q:Is this an AI caption generator? Does it upload my script?
No AI and no uploads. You provide the script; the caption generator builds the video in your browser with FFmpeg. Your text never leaves your device. It’s an auto caption generator in the sense that it automatically times and styles captions from your script — not speech-to-text.
