Synthesys IO

Synthesys IO is an AI-powered content creation platform that provides tools for generating voice, video, and images at scale. Its core capability is transforming written scripts or prompts into natural-sounding voiceovers, realistic AI avatar videos, and on-brand visual assets without requiring specialized production skills. Users can choose from a library of AI voices in multiple languages and accents, adjust tone and pacing, and generate audio suitable for tutorials, ads, product demos, and e-learning content.

The video generator combines AI voices with customizable human-like avatars and backgrounds, enabling the creation of explainer videos, training modules, and social media content directly from text. The image generation tool allows users to create visuals based on descriptive prompts, useful for marketing graphics, thumbnails, and illustrative content. Synthesys IO typically offers a browser-based interface, making it accessible to non-technical users and teams.
