subMatik vs Auto Captions

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.

Your video is good. It just doesn't look edited. Charlatan listens to your video, writes down every word, and lets you decide how it looks — from 99 fonts, not the same three everyone else is using. PICK A VIDEO. THAT'S THE WHOLE SETUP. Choose a clip from your library or record one right there. Charlatan transcribes the audio and lays the subtitles onto the timeline, synced to what you actually said. 78 FONTS, AND THEY ARE THE POINT Impact, condensed, handwritten, marker, stencil, inline, serif. The font is what makes a caption look like yours instead of like a default. Browse by category and see each one on your own video before you commit to it. WORD BY WORD, OR PHRASE BY PHRASE Three subtitle paces: one word at a time for the classic short-form look, short punches of two or three words, or full sentences that are easier to read. Karaoke highlight lights each word up exactly when it is spoken. MAKE IT LOOK LIKE YOURS Size, position, tilt, letter spacing, ALL CAPS, colour, outline, shadow and marker highlight. Drag the subtitle anywhere in the frame, pinch to resize it. Save a style once and reuse it on every video, so everything you post looks like it came from the same place. REFRAME FOR WHERE IT IS GOING Export 9:16 for short-form, 1:1 for the feed, 16:9 for wide — or keep the original framing. TRANSLATE IT Record in one language, export the subtitles in another. EVERYTHING HAPPENS ON YOUR IPHONE The audio never leaves your phone. No account, no upload, no server, nothing to sign up for. It works on a plane. WHAT'S INCLUDED 17 fonts, the full style editor, and export. CHARLATAN PRO All 99 fonts, karaoke word-by-word highlight, translation, reframing to 9:16 / 1:1 / 16:9, saved styles, videos of any length, and no watermark.
