What is the MultiHub Auto-Subtitle Generator?
A fast, free AI tool to automatically caption your videos. Adding subtitles usually requires expensive subscriptions or time-consuming manual typing. MultiHub uses powerful AI to instantly transcribe your speech and burn professional captions into your video without any watermarks or slow wait times.
Why Add Subtitles to Your Videos?
If your video doesn't have captions, you are losing viewers. Studies show that over 80% of users scroll through social media platforms like TikTok, Reels, and Facebook with their sound muted. Subtitles instantly hook the viewer's attention, dramatically increase your watch time, and ensure your message lands even in complete silence.
Beyond engagement, auto-captions make your content fully accessible and give you a raw text transcript that you can easily copy and paste into your video's description for an massive SEO boost. If you are preparing a landscape video for social media, make sure to use our Aspect Ratio Resizer to format it vertically before burning in your text.

Frequently Asked Questions
Are there any watermarks added to my video?
No. MultiHub is a professional tool built for creators. We will never add watermarks or branding to your exported files, ensuring your content is immediately ready for publishing.
What is the difference between "Embed" and "Burn" Subtitles?
Embedding adds a hidden subtitle track to the MP4 file that viewers can turn on or off (like YouTube Closed Captions). Burning permanently draws the text directly onto the video frames using your chosen font style, meaning the captions are always visible and cannot be turned off. Burning is best for social media.
