What is mindwendel?
mindwendel is a Phoenix LiveView application for collaborative brainstorming. Teams can create challenges, invite participants anonymously without registration, and collect ideas with live upvoting. Ideas can be organized with custom labels, lanes, and drag-and-drop ordering. The app supports encrypted file attachments via S3-compatible storage, link previews, comments, and export to HTML or CSV. AI-powered idea generation works with OpenAI and OpenAI-compatible APIs (e.g., local LLMs, Mistral). Brainstormings auto-expire after a configurable period (default 30 days) for GDPR compliance. It runs via Docker Compose with PostgreSQL and an S3 backend (rustfs), or on Gigalixir. The UI is available in English, German, and Italian.
