subMatik vs Subvibe

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.

Auto-captions are never right the first time. A name is misspelled, two lines are merged, the timing drifts by half a second — and most apps give you no way to fix any of it. Subvibe gives you the timeline. Tap a word to retype it. Drag a block to retime it. Split, merge, restyle — then translate the whole track into any of 20 languages and export it as a clean .srt file or burn it straight into the video. Your video never leaves your iPhone — only the audio is used to generate subtitles. Prefer full privacy? Switch speech recognition to on-device mode and work with no connection at all. • SUBTITLE EDITOR — retype, split, merge and restyle every line on the timeline • EXACT TIMING — drag blocks to fix drift and match speech frame by frame • TRANSLATE ON DEVICE — 20 languages, nothing uploaded, no account • AUTO SUBTITLES — accurate speech-to-text, in the cloud or right on your device • BEAUTIFUL STYLES — fonts, colors, outlines, backgrounds, and one-tap designer templates • ANIMATIONS — word-by-word reveal and highlight effects that pop on social • EXPORT YOUR WAY — save video with burned-in subtitles, or export an SRT file • ON-DEVICE MODE — switch speech recognition to your device and work fully offline Perfect for creators, editors, and anyone who wants clean, accurate subtitles without sending their videos to the cloud.
