Longbatman09/Report2Plot ? reverse-engineered prompt

Build me a simple tool called Report2Plot that helps a teacher or school admin turn student report files into something useful without manual data entry.

I want a small browser based app where I can upload report cards or mark sheets as PDFs or images, then the app should read the student names, subjects, and marks, organize that into clean structured data, and automatically create charts that show performance clearly. It should also generate a presentation ready PowerPoint summary I can download. Please keep a history of past runs and save processed results locally so if I upload the same report again it does not waste time or repeat paid AI extraction.

Make it easy to run on Windows with one click if possible, and have the app save outputs in a clear output area. If there is missing or messy data, handle it as gracefully as you can. Use Gemini for the smart extraction part, and look up current docs online if you need to.
