Users can now save new vocabulary directly from ChatGPT to the VibeLing mobile application. The integration utilizes the Model Context Protocol (MCP) to allow the AI to interact with the external service.

To enable this functionality, users must install the VibeLing app on iOS or Android and create an account. The feature requires a Pro subscription, though a 3-day trial period is available for testing.

The setup process involves connecting a custom MCP server within the ChatGPT browser interface. Users must authorize the connection by entering a code generated in the VibeLing mobile app.

The MCP integration is compatible with other AI assistants, including Claude, Claude Code, Cursor, and Codex. This allows users to save words to the same dictionary while using different platforms.
