Notta is an AI-powered transcription and note-taking service headquartered in Tokyo, Japan, founded in 2021. The platform converts audio and video content into text in real time, supporting over 50 languages, and is designed for use in meetings, interviews, and recorded media.
Notta's core product integrates with video conferencing platforms such as Zoom, Google Meet, and Microsoft Teams via a bot that joins calls to capture and transcribe conversations. The service also offers automated summarization, speaker identification, and action item extraction. It targets individual professionals, teams, and enterprises seeking to reduce manual note-taking.
The company operates on a freemium model with paid subscription tiers for individuals and teams. Specific funding details and investor information have not been publicly disclosed. Notta has grown its user base across North America, Europe, and Asia since launch.
