Description
Captora turns any phone video into a captioned, ready-to-post clip in seconds. It transcribes with word-level timing, syncs to your audio, and burns in captions with one of 52 customizable styles you can save as a template. Works in 17 languages with auto-detection. Your video never leaves your device: only the audio is sent for transcription, then deleted immediately, while the final render happens locally. Built for creators shipping to TikTok, Reels and Shorts.

Could you build this?
Partial Although sending audio to a transcription API is simple, on-device video rendering, precise word-level subtitle alignment, font rendering, and performant hardware-accelerated video export on mobile require specialized media engineering.
What it would actually take: The app needs a pipeline leveraging AVFoundation (iOS) or Android MediaCodec alongside an STT service (e.g., Whisper API returning word timestamps). The hard engineering piece is building a performant client-side video composition engine (Metal/OpenGL/AVVideoComposition) that dynamically animates 52 typography styles synchronized accurately with audio and exports high-definition video without crashing device memory limits.
