AI Content Creation Platform

I want to build a web-based platform that lets users generate three kinds of content on demand—written copy (articles, posts, emails), marketing graphics and illustrations, and short-form videos—through a single, intuitive interface powered by generative AI.

Here is the vision in plain terms:

• A clean dashboard where a user selects “Text”, “Image”, or “Video”, enters a brief prompt, chooses a style or template, and receives usable output within seconds.
• Modern generative models behind the scenes (e.g., GPT-style LLMs for text, diffusion or image-first models for graphics, and an API-driven video generator) stitched together under one authentication, billing, and analytics layer.
• Real-time preview and lightweight editing tools so users can polish the AI’s result before downloading or exporting.
• Project history stored per account, allowing re-generation or fine-tuning of previous work.
• Scalable cloud architecture that can add new model endpoints without disrupting existing users.

Deliverables I need from you:

1. A functioning MVP deployed to a cloud host (AWS, GCP, or similar) with user sign-up, credit/usage tracking, and the three generation pipelines live.
2. Source code with clean documentation covering model calls, front-end components, and infrastructure scripts.
3. A brief technical read-me outlining how to extend the system with additional models or languages.

Acceptance criteria:

• A new user can register, generate at least one sample text, image, and video, edit the output, and download the result without errors.
• Average generation time for each content type stays within reasonable limits (text
