## Product

Dub-Dub.ai is a pay-as-you-go platform. One upload can produce a timestamped transcript, publish-ready subtitles, speaker-identified dialogue, and multilingual translations — all in a single workflow.

### AI Transcription
Upload any audio or video file and receive a timestamped, accurate transcript within minutes. The engine handles accents, overlapping speech, background noise, and fast-paced delivery.

### Subtitle Generation
Produces perfectly timed captions from the transcript. A visual editor allows users to adjust timing, correct individual lines, and fine-tune output without switching tools. Export formats: SRT, VTT, Word (.docx), or subtitles burned directly into an MP4. Supported platforms include YouTube, TikTok, Instagram, LinkedIn, and broadcast workflows.

### Speaker Identification
Automatic speaker diarization detects and separates every voice in a recording. The editing interface supports drag-and-drop reassignment, colour-coded labels, bulk reassignment, and inline corrections. No technical knowledge required.

### Translation
Translates transcripts and subtitle sets into 150+ languages in a single step. Designed to replace agency or freelancer invoices for localisation workflows.

### API Access (Coming Soon)
A developer API with MCP (Model Context Protocol) support is in development. It will enable Dub-Dub.ai to run as an agent inside automated pipelines, connecting transcription and subtitle generation directly to existing content stacks and AI-assisted workflows.
