Advanced AI Transcription Technology

How AI Speech Recognition Works

Our tool utilizes state-of-the-art Automatic Speech Recognition (ASR) neural networks. These models analyze audio waveforms to identify phonemes, assemble them into words, and determine the precise start and end times of each spoken word. This technology allows for "timestamping" at the word level, providing far greater accuracy than traditional sentence-level transcription.

Benefits of AI vs Manual Transcription

Manual transcription allows for human nuance but is slow and expensive (often $1-2 per minute). AI transcription provides near-instant results at a fraction of the cost. For content creators producing frequent videos, AI offers the perfect balance of speed and acceptable accuracy, allowing you to scale your content production without breaking the budget.

Supported File Formats Explained

We support the most common web and professional media formats. Video formats like MP4 and MOV are ideal for final edits. Audio formats like MP3 and WAV are perfect for podcasters or if you want to extract subtitles from a voice-only recording. Our system handles the conversion and audio extraction automatically.
