CapFlow: Captions & Subtitles

CapFlow makes it easy to add subtitles to any video. It's a subtitle maker and auto caption generator that turns speech into editable, time-synced captions — style them and burn them into the video, or export a subtitle file. No watermark.

Built for TikTok, Reels, and YouTube Shorts creators — and anyone who wants clear, accessible video — CapFlow helps you create and customize captions and subtitles.

WHY CAPFLOW
• Automatic captions with editable, word-level timing
• Karaoke word-by-word highlighting that follows the speaker
• Full control over how your captions look and read
• No watermark on your exported video
• Export a captioned video or a subtitle file (SRT / VTT)

FEATURES

• Full caption editor — tap to fix text, split or merge lines, and drag to retime (snaps to words)
• Caption styles — Clean, Bold Outline, Karaoke, Pill, Minimal, and Neon presets, plus custom fonts, colors, size, and position
• Animated captions — word-by-word karaoke highlight for that viral short-form look
• Translate subtitles — translate captions into 50+ languages, or transcribe-to-English in one tap; export a bilingual SRT
• Reframe for any platform — 9:16, 1:1, or 16:9 canvas with blurred fill for TikTok, Reels, Shorts, and feed videos
• Filler-word cleanup — flag and remove "um" and "uh" with one tap
