Synthesia

Synthesia is a cloud-based platform that allows users to create professional-quality videos using artificial intelligence, without the need for cameras, studios, or actors. The core function is to convert text into video by selecting from a library of AI-generated avatars that can speak the input text with natural-sounding voiceovers. These avatars are not pre-recorded humans; they are synthetic characters generated by deep learning models that can lip-sync accurately to any spoken text in over 160 languages and accents. The platform is designed for business use, particularly for internal communication, training, sales enablement, customer support, and marketing. Users start by typing or pasting a script into the web-based editor. They can then choose an avatar from a diverse set of options, including different genders, ages, ethnicities, and styles—ranging from realistic humans to more stylized characters. Alternatively, users can upload a short video of themselves or a colleague to create a custom avatar that mimics their appearance and gestures. Once the avatar is selected, the platform automatically generates the voiceover using text-to-speech technology that supports multiple languages and tones, including neutral, professional, friendly, or enthusiastic. Users can preview the video instantly and make adjustments, such as changing the avatar’s background, adding text overlays, inserting images or screen recordings, and adjusting the pace of speech. The editor also supports collaboration features. Multiple team members can work on the same video project simultaneously, leave comments, and propose changes in real time, which is especially useful for remote teams or departments that need to produce videos regularly. Additionally, Synthesia includes a translation featu
