Technical Integration & Capabilities

Note: Captions does not currently expose a public REST API. All functionality is accessed via its web app or mobile clients (iOS/Android).

Core AI Pipeline

  • AI Edit Engine: Ingests raw video and performs content-aware scene segmentation, B-roll matching, zoom/cut generation, music sync, and transition application — all driven by style templates.
  • Chat-Based Editor: A natural language interface that accepts prompts to modify edit parameters (e.g., "make the pacing faster," "add a fade between scenes"), enabling iterative refinement without manual timeline editing.

Avatar & Actor Generation

  • Generate digital twins from selfies or use pre-built AI actors.
  • Supports outfit swapping, background replacement, and product placement overlays.
  • Reusable actor IDs allow consistent branding across multiple video projects.

Language & Accessibility

  • Auto-caption generation with customizable styles and color schemes.
  • Translation and dubbing pipeline supporting 30+ languages with AI lip sync alignment.

Media Enhancement

  • Eye contact correction: Algorithmically adjusts gaze direction to simulate direct camera contact.
  • Noise removal: Isolates and suppresses background audio artifacts.
  • Pause/filler trimming: Detects and removes dead air, filler words, and interruptions.

Platforms & Deployment

  • Web app (browser-based, no install required)
  • iOS app (App Store)
  • Android app (Google Play)
  • Supports vertical and horizontal video output formats for multi-platform publishing.
