ChaiPlanets/paperdoodle ? reverse-engineered prompt

Build me a simple web app where I can upload a research paper or paste in its text, and it turns it into a short executive style brief that a busy manager could read quickly.

I want the app to summarize the paper in plain English, pull out the key takeaways, why it matters, and any risks or next steps, then also generate a simple conceptual doodle that visually captures the main idea. Make it feel polished and easy to use, with a clean page for uploading or entering content, a results page for the brief, and a place to show the doodle beside it.

Use the existing project structure if it helps, and keep it working as a small Python app. If you need current docs for any AI or image generation tools, look them up online. Please also make sure it handles errors nicely when the input is missing or the paper is too large.
