Store description excerpt
Lazy Captions adds accurate, karaoke-style captions to any video — entirely on your iPhone. No internet. No account. No cloud AI subscription. Just pick a video, tap a button, and get a captioned video saved to your gallery. HOW IT WORKS Lazy Captions uses Whisper — an open-source speech recognition model — running fully on your device. It transcribes every word, syncs each one to the exact moment it was spoken, and burns the captions directly into your video. The result looks like the word-by-word highlights you see on social media, built right into the file. KARAOKE-STYLE WORD HIGHLIGHTS Each word lights up as it's spoken. Prior words stay white. Upcoming words stay hidden. Pick from 8 highlight colors or keep the default gold. The style scales automatically to fit any video size or orientation. COMPLETELY OFFLINE, ALWAYS Once a Whisper model is downloaded, nothing ever leaves your device. No API calls, no server processing, no usage tracking. Caption the same video ten times with no internet — it works the same every time. FOUR ACCURACY TIERS Choose the model that fits your needs: - Tiny (75 MB) — fastest, good for clear speech - Base (142 MB) — fast with solid accuracy - Small (466 MB) — recommended balance of speed and accuracy - Turbo (874 MB) — highest accuracy, slower processing Models download once and stay on your device. ONE-TIME PURCHASE, NO SUBSCRIPTION 10 free captions to start, no sign-up required. A single one-time purchase unlocks unlimited captions forever. No monthly fee. No annual renewal. Buy once, use it as long as you want. WORKS WITH YOUR EXISTING VIDEOS Import MP4, MOV, and other common formats directly from your Files or Photos. The captioned video is saved back to your gallery, ready to share anywhere.
