How it works
How to generate automatic subtitles for your research videos
The qualitative data analysis process requires precision and agility. To get started, simply access our platform and upload your video file in MP4, MKV, or WEBM format. We support large files up to 5 GB, which is ideal for long research session recordings. After uploading, our AI, powered by the AssemblyAI engine, processes the audio with an accuracy ranging between 94% and 97%. In just a few minutes, you will have synchronized text ready for review or export. To ensure the best experience, we offer 30 free minutes every month, with no credit card required. It is the ideal solution for researchers looking for a robust alternative to tools like Happy Scribe or Trint, with a total focus on high-quality transcription.
