VideoCaptions.ai

VideoCaptions.AI is a web‑based tool that generates word‑level captions for uploaded audio or video files, synchronizing the text to the audio track. The service transcribes the audio, applies animated text effects, and exports the result as an MP4 with captions burned in. It supports common audio formats (MP3, WAV, M4A) and video formats (MP4, MOV, WebM) that browsers can decode, and it processes files locally in the browser, sending only the audio for temporary transcription before deletion.

The generator offers a range of caption styles—such as flash, reveal, pop, and highlight—and animation effects like fade, bounce, glitch, and neon pulse, with per‑word styling options and a selection of 52 Google Fonts. Users can choose from more than 99 supported languages, including English, Hindi, Spanish, Arabic, and others, and export videos in a 9:16 aspect ratio suitable for Instagram Reels, TikTok, and YouTube Shorts.

The platform provides a free tier of 300 monthly credits, covering roughly four standard‑quality videos, and a paid Creator plan for additional usage. No watermarks are added to exported videos, and the entire workflow—from upload to export—typically completes in under three minutes.
