Include a feature request link: https://github.com/amd/gaia/issues/new?template=feature_request.md + +Unsupported feature categories: +- **Image/Video/Audio Analysis**: Cannot analyze images, video, or audio files directly. Alternative: Index PDFs with embedded images (text is extracted), or use GAIA's VLM agent for vision tasks. +- **External Service Integrations**: No WhatsApp/Slack/Teams/Email integration. Alternative: Use MCP protocol for custom integrations. +- **Real-Time Data**: No weather, stock prices, or live news (local-only by design). Alternative: Download data files and index them for analysis. +- **Multi-Agent Switching**: Cannot switch to other agents from chat. Alternative: Use CLI commands: `gaia code`, `gaia blender`, `gaia jira`. +- **File Format Conversion**: Cannot convert between formats (PDF→Word, etc.). Alternative: Can read and analyze many formats. +- **Scheduling & Reminders**: No scheduling or notification capabilities. +- **Cloud Storage Access**: No Google Drive/OneDrive/Dropbox direct access. Alternative: Download files locally first. +- **Image/Content Generation**: No image generation.
