Mindwendel

The application provides a web‑based workspace where team members can create brainstorming sessions, submit ideas, and vote on them in real time. Participants can join anonymously without registration, optionally adding usernames, and can organize ideas with custom labels, lanes, drag‑and‑drop ordering, and comments. Features include encrypted file attachments stored on an S3‑compatible backend, AI‑assisted idea generation via OpenAI‑compatible APIs, and export of results to HTML or CSV. Sessions are automatically removed after 30 days to aid GDPR compliance.

It is built with Elixir, the Phoenix framework, and Phoenix LiveView, using PostgreSQL for persistence. The software can be deployed via Docker Compose, with a production‑ready Docker image and simple setup scripts. Localization files are provided for English and German, and the code is released under the AGPL‑3.0 license, allowing self‑hosting and free use without subscription.

The tool targets developers, product teams, and any groups that need quick, collaborative idea generation and prioritization. Its open‑source nature and minimal setup time make it suitable for internal use in organizations that prefer to run the service on their own infrastructure.
