CapSnap: AI Video Captions

CapSnap is the fast, private AI video captions app that adds stunning, animated subtitles to your content — with speech-to-text that runs entirely on your iPhone. No account. No uploads. Your footage never leaves your device.

Drop in a clip, pick a style, and CapSnap auto-transcribes every word with frame-accurate timing. Tap any word to fix it, recolor it, or give it a bounce. Export a captioned video for TikTok, Instagram Reels, YouTube Shorts, podcasts, vlogs, ads, and lessons — in under a minute.
