mindwendel is a web application for running structured brainstormings and prioritizing ideas with teams. It provides anonymous, real-time idea capture, upvoting and lightweight planning features built with Elixir and Phoenix.
Key Features
- Real-time brainstorming board with live updates and drag-and-drop lanes
- Anonymous or optional-username participation and upvoting for ideas
- Labeling, clustering and filtering of ideas; comments on items
- Encrypted file attachments stored on S3-compatible backends (example: MinIO)
- AI-powered idea generation via OpenAI-compatible APIs (configurable, disabled by default)
- Export ideas to HTML or CSV and configurable automatic deletion of sessions for GDPR compliance
- Docker compose deployment and production-ready configuration with PostgreSQL and background job runner
Use Cases
- Run quick team ideation sessions and capture prioritized suggestions during workshops
- Collect and cluster solutions or feature ideas for product planning and retrospectives
- Facilitate anonymous feedback or lean-coffee style decision-making with voting
Limitations and Considerations
- AI idea generation depends on external OpenAI-compatible APIs and may incur usage costs; features are disabled by default
- Default configuration removes brainstormings after a retention period (30 days) which may not suit long-term archival unless adjusted
mindwendel is focused on fast, low-friction group ideation with simple moderation and export capabilities. It is suitable for teams that need ephemeral, privacy-conscious brainstorming with optional AI assistance.
