CapScribe: Auto Captions

CapScribe turns speech into editable captions and writes them into your video on your iPhone. Import a video or audio file, transcribe it, correct the words and timing, choose a style, and export. Already have captions? Pair a video directly with an SRT or VTT file and skip transcription. You can also send media to CapScribe from the Share menu in Photos or Files. CREATE AND EDIT • Transcribe imported video and audio on your device • Keep multiple local video and audio projects, then search, rename, duplicate, reopen, or delete them • Burn styled captions into the exported video • Choose from eight presets or customize font design, alignment, colors, outline, background, corners, and shadow • Add a clean Pop or Rise entrance to captions, or keep motion off • Reframe output for the original ratio, 9:16, 4:5, 1:1, or 16:9 • Preview at 0.5×–2× speed and loop the current caption while editing • Enter exact timecodes, smart-split a caption, or safely fix empty and overlong captions in one step • Review low-confidence, fast, overlong, and empty captions in one place • Use the explainable on-device Publish Readiness score to find deterministic caption issues before watching the final cut • Reuse an on-device term dictionary for names and commonly misheard words • Undo and redo edits, or find and replace across original text and translations TRANSLATE AND EXPORT • Translate captions with Apple's system Translation framework • Switch between original, translated, and bilingual captions • Batch-caption up to 10 videos at a time • Export original, translated, or bilingual SRT, VTT, and TXT files separately or as one package • Preview the finished video, compare source-to-output resolution, and check expected duration, frame rate, audio, and file size before sharing FREE PREVIEW AND FULL VERSION Try the complete workflow at no charge. For longer media, the free preview processes the first 90 seconds of each video or the first 10 minutes of audio. A one-time, non-consumable in-app purchase removes those free preview limits. There is no subscription or watermark; actual processing capacity depends on your device and media. PRIVACY CapScribe processes your media and transcripts on your iPhone and does not upload them to the developer. Projects stay in the app's local storage. iOS may download Apple speech or translation language resources when first needed. Purchases are handled by Apple through the App Store. REQUIREMENTS iPhone with iOS 26 or later.
