Canva

Canva is a comprehensive visual communication platform that enables users to create a wide range of designs, from presentations and social media posts to videos and websites. It offers a vast library of templates, a suite of editing tools, and integrates AI-powered features through its 'Magic Studio' to simplify content creation. The platform supports collaboration and is accessible across various devices.

Canva is a strong match for the described concept. It offers a wide array of design tools, many of which are AI-powered ('Magic Studio'), that function through guided interfaces rather than raw prompts. It provides numerous templates and styles, a categorized catalog of tools, and robust user authentication with free and pro tiers. The platform supports search and filtering, collaboration, and is available across multiple devices, including mobile. While it doesn't explicitly state 'multi-model integration' or 'custom prompt templates' in the same way the concept does, its 'Magic Studio' implies an underlying AI system that selects the best approach for the task, and its extensive template library serves a similar purpose to presets. The 'Magic Studio' features like Magic Write, Magic Design, Magic Media, and Magic Switch align well with the idea of specialized AI tools.
