Souna AI is an application that provides AI-powered chat, image generation, and video generation tools. It offers unrestricted AI conversation within the boundaries of the law, along with the ability to create images, product ads, and short videos that include sound. Each account includes free daily AI chat up to a limit, and all generated content is stored in a private library. The application states that this content is never published, sold, or used to train AI models. The application includes several named models for different purposes. Souna Lumen produces high-resolution product and campaign images, while Lumen Lite generates fast, lower-cost drafts for testing ideas. Souna Prism is used for styled and artistic image looks, and Souna Motion and Motion Lite generate videos with sound from a single photo or a text prompt, with Motion Lite providing quicker, lighter output for drafts. The tools also include a photo editor with layers, photo grading, a video timeline editor, motion effects, and audio capabilities. Additional models are available through a tier called Director, including Veo 3 Fast, Seedream 5.0 Pro, and private models that accept any lawful idea. Reference images can be attached to keep a face, product, or style consistent across outputs. A typical workflow starts with writing an idea, after which the application drafts a script and shot list, builds a storyboard, and generates video clips with sound and audio levelled for social platforms. Users can upload a product photo to produce a 10 or 15 second advertisement video with optional voiceover, or cut a product onto a white background for marketplace listings. Exports are available in formats such as 1:1, 4:5, 9:16, and 16:9. Monthly credits are used for image and video generation, with roughly 55 standard images or one six-second 1080p video available per credit pack, and credits remain valid for one month after arrival. The application is built on a selection of image and video models, including ChatGLM, Qwen, Gemma, DeepSeek, and Aion, tuned and named by Souna.
