AI Subtitle Generator
Voice2Sub is built for file-based subtitle work: import media from your computer, choose the spoken language, generate AI subtitles, review generated files before publishing, then export a subtitle or transcript format that fits your destination.

When recognition gives you a strong first draft, open the result in the editor to fix wording, check line breaks and tune timing before export.
Workflow
The app keeps the workflow predictable for short clips, long recordings and repeat caption jobs.
Open an MP4, MOV, MKV, WAV, MP3, M4A or another supported media file from your computer.

File-based workflow
Start from a video, audio, podcast, interview or screen recording file, generate reviewable subtitles, then check names, punctuation and recognition mistakes before using the output professionally.
AI subtitle generator
When a project needs English subtitles, Voice2Sub can create English-only output or keep the original subtitle output plus a separate English file while staying in the desktop workflow.
Review layer
Automatic subtitles should not be published blindly. Use Voice2Sub to check names, punctuation and generated files before exporting. That review step turns a fast AI draft into a file you can hand to an editor or platform.
Export decision
SRT works well for broad subtitle exchange and handoff. VTT is common for web players and browser caption workflows. TXT is best when you want readable transcript text, while LRC and CSV support timestamped or structured export files.
Positioning
Voice2Sub is not trying to be another online upload box. It is for people who prefer a local app for long recordings, private files, repeat subtitle jobs and media that already lives in a desktop editing workflow.
AI Transcription
Voice2Sub also covers speech to text, audio to text, video transcription and Whisper AI transcription workflows, so subtitle generation stays connected to transcript and documentation workflows.
