subMatik vs CapScribe

subMatik turns your iPhone into a complete subtitle studio. Drop in any video — vertical Reels, horizontal interviews, podcast audio — and get clean, timed captions in seconds. Transcription, burn-in, and export run on-device; translation is on-device with Apple Translation, or via Google/DeepL if you choose. WHAT MAKES SUBMATIK DIFFERENT • 100% on-device transcription via the Whisper speech model (WhisperKit). Your audio never touches a server. • 70+ languages supported, including Turkish, Chinese (Simplified + Traditional), Japanese, Korean, Thai, Khmer, Lao, Burmese, and more. • Context-aware translation. Each segment is translated alongside its neighbors so idioms and homonyms come out right. • Vertical-friendly subtitle placement. The Position Picker has a 3×3 anchor grid + drag-to-tune fine adjustment over a real frame from your video — no guessing. • Reels mode. Chops cues into 1–5 word bursts that read fast on phone screens. • Burn subtitles into the video pixels. Export an MP4 with captions baked in, ready for Instagram / TikTok / YouTube Shorts. Save directly to Photos. • Re-translate any existing SRT into a new language without re-running Whisper. • Files-app integration. Right-click any video → "Open in subMatik" → ready to caption. • No account, no ads, no analytics dragnets. Optional anonymous crash telemetry via Apple MetricKit only. WHY ON-DEVICE MATTERS Modern Whisper models run entirely on your iPhone. There's no reason to upload your private conversations, family videos, work recordings, or proprietary content to someone else's server just to get subtitles. subMatik proves that the highest-quality transcription can be the most private one too. OUTPUT FORMATS • SRT (universal, supported everywhere) • Burned-in MP4 (subtitles in pixels, no separate file needed) PRO TIPS • "Upper third" position preset keeps subtitles clear of TikTok / Reels bottom UI. • Long-press any file in the queue to set a custom subtitle anchor just for that clip. • DeepL users: paste your API key in Settings for higher-quality translations on European languages. • On first launch you choose a Whisper model — from a fast ~150 MB option up to the highest-accuracy one. It downloads once (use Wi-Fi). After that, transcription is fully offline. REQUIRES iOS 26.0 OR LATER. Works on iPhone 11 and newer. Best experience on iPhone 14 Pro and newer.

CapScribe turns speech into editable captions and burns them into your video, entirely on your iPhone or iPad. Nothing is uploaded to us. There is no subscription, no credit system, and no watermark: one purchase unlocks the full app. Import a video or audio file, transcribe it on device, fix words and timing, pick a style, and export. Already have captions? Pair a video with an SRT or VTT file and skip transcription. Batch up to 10 videos at once. Because everything runs locally, there is no upload queue and no waiting for a server. After the language pack is downloaded, transcription works in airplane mode. 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 on-device Automatic Checks to find detectable caption and timing issues, then listen and review names, numbers, original text, and translations before publishing • 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 or iPad 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.
