Subtitle Artisan: Offline AI

Private captions, shaped by you. Subtitle Artisan turns local video, audio, or a microphone recording into editable timed captions without uploading your media to the developer. ON-DEVICE TRANSCRIPTION Choose a video, audio file, or microphone recording. Download a speech model once, then transcribe locally with visible progress and recoverable background work. PRECISE SUBTITLE EDITOR Play the source media, inspect every subtitle segment, adjust text, split or merge segments, search and replace, and keep timestamps aligned. FILES YOU CAN USE Export SRT, timestamped text, or plain text through the system share sheet. Pro adds VTT, bilingual SRT, and burned-in video. OPTIONAL BILINGUAL CAPTIONS On supported iOS 18 or later devices, Apple Translation can create bilingual caption layouts on device after the required language resources are available. LOCAL-FIRST BY DESIGN No account, ads, analytics, tracking, or developer cloud. Your media, transcript, projects, and exports stay under your control on the device unless you explicitly share them. TRY THE CORE WORKFLOW, THEN BUY ONCE The free tier transcribes media up to five minutes and exports core caption formats. One lifetime Pro purchase removes that duration limit and unlocks every Pro feature. There is no subscription.
