SozAI is developed by Vastflow, although the company has not publicly identified an individual founder on its official website. Built to make speech-to-text simple and highly accurate, SozAI helps users transcribe audio and video into searchable text, generate AI summaries, create subtitles, identify different speakers, and translate conversations in over 100 languages. It is widely used by students, researchers, journalists, healthcare professionals, lawyers, podcasters, and business teams because of its fast processing, speaker diarization, high transcription accuracy, and strong privacy protections with AES-256 encryption and EU-based data centers. The platform also offers AI note-taking, meeting recording, YouTube transcript generation, and AI writing tools, making it an all-in-one productivity solution for spoken content. Pricing starts with a free plan that includes 30 minutes of transcription with no credit card required, while paid plans unlock additional transcription time and advanced features.
