chrisrimmer1/whatsapp-analyzer-railway — reverse-engineered prompt

Build me a simple web app that lets someone upload an exported WhatsApp chat and turn it into useful summaries with AI.

The user should be able to upload a WhatsApp .zip or .txt export, choose whether they want action items, shared links, or check in mood trends, and optionally pick how many recent days to analyze. The app should show clean interactive results in the browser, with tasks grouped clearly, priorities and statuses shown with friendly icons, links explained with context, and check ins shown as a simple graph by person over time.

It should use an OpenRouter API key from the environment for the AI analysis, with a sensible default model, and optionally support Google Docs or Drive links if a Google token is provided. Keep the upload flow simple and make sure files are handled safely, with temporary files cleaned up after use.

Please make it easy to run locally and deploy on Railway. Look up current docs online if needed.
