Lovable: Excalidraw+ Connector Turns Whiteboards Into Prototypes

LovableOct 6, 2026View original changelog

Lovable added an Excalidraw+ chat connector that lets the agent list, search and edit scenes in a user's Excalidraw+ workspace, including diagrams, wireframes and presentations. Existing whiteboards can serve as context for building prototypes. The connection is personal and works only in project chat, not in published apps.

Key Takeaways

Lovable can now list, search and edit Excalidraw+ scenes directly from chat.
Existing diagrams, wireframes and presentations can act as context for building working prototypes.
Authentication is a personal API key from Excalidraw+ settings, so each teammate connects separately.
It is a chat-only connector: it does not run in published apps and visitors cannot reach Excalidraw+ through it.
Chat connectors are on by default for all plans, including Enterprise.
Business and Enterprise admins can disable Excalidraw+ individually or turn off chat connectors workspace-wide.

Whiteboards as build context

Lovable introduced an Excalidraw+ chat connector with the tagline "Turn whiteboards into working prototypes." Once connected, Lovable can list, search and edit scenes in the user's Excalidraw+ workspace, covering diagrams, wireframes and presentations. That lets a team start from sketches it already has and have Lovable use them as context while building a prototype.

Setup and scope

The user opens Connectors, selects Excalidraw+, adds a connection (choosing Chat connector if prompted) and authorizes with an API key from their Excalidraw+ settings. The connection is personal, so only the person who created it can use or manage it, and teammates connect with their own keys.

The connector works only in project chat and in Chats. It is not part of the published app, so app visitors cannot reach Excalidraw+ through it.

Availability

Chat connectors are enabled by default on all plans, including Enterprise. On Business and Enterprise, workspace admins and owners can turn off chat connectors for the whole workspace or disable Excalidraw+ individually.
