This example shows how to build a collaborative text editor with an AI toolbar using Liveblocks, Lexical, Vercel AI SDK, and Next.js.

As users edit the document, changes will be automatically persisted and synced—allowing for an editor that updates in real-time across clients. Users will also be able to see who see each other’s cursors in the document. Query AI to generate improvements and new content.
