The free account allows users to create a vocabulary for unlimited overdubs, while the pro account provides access to multiple voices that fit the user's preferred style setting. Descript also provides editing, recording, transcription, publishing, and sharing services, as well as AI-powered tools. It is available in 22 languages and data is securely stored in the cloud with full version history. Collaborators can access the data from anywhere. The free plan is available with no credit card required to get started, while paid plans start at $12 per month. Descript also offers a White Glove service for up to 99% accuracy in an average of 24 hours. This powerful AI tool is suitable for editing, workflows, storytelling, video editing, security and more.
