What it is

What socaptions.com looks like

SoCaptions is an AI video caption generator designed for creators. Upload a video in MP4, MOV, or WebM format, and the service uses Whisper-powered AI to transcribe it with word-level timing accuracy in seconds. Choose from viral-ready caption styles like Bold Outline, Box, Cinematic, Karaoke, Emphasis, and Animated, then export a clean burned-in MP4 ready to publish. The captions are baked into the video pixels, so they survive downloads and reposts without requiring separate subtitle files. The service supports 99 languages with automatic detection. SoCaptions also includes free in-browser tools for subtitle conversion, safe-zone previews, and caption guides, with no signup required.

Quick answers

How do I add captions to a video?
Upload your video, let the AI transcribe in 10–15 seconds, pick a style, and export as MP4. The captions are burned into the video, so they play on every platform without an extra subtitle file.
Do captions actually increase watch time?
Captions can improve comprehension and retention when viewers watch without sound, and they help people follow speech in noisy environments or a second language. However, results depend on the hook, pacing, audio, and caption quality — captions are an aid, not a guaranteed performance lift.
What's the difference between subtitles and closed captions?
Subtitles usually transcribe spoken dialogue. Closed captions also describe relevant non-speech audio (music, sound effects, speaker IDs) and are the safer choice when an accessibility requirement applies.
How much does SoCaptions cost?
The free tier offers 5 minutes of transcription with edit-only access (no export). Pro costs $5/month or $50/year, with 100 minutes of transcription and 100 minutes of MP4 export every month. You can cancel any time.
What font should I use for captions?
Use a heavy sans-serif with a thick black stroke or a solid background plate. Inter Black, Montserrat Black, and Anton are reliable defaults. Avoid thin fonts — they break apart on compressed video.
