nnuer

nnuer is a library and community for UI blocks made with AI. Each block (hero, pricing, features, footer, and more) is saved together with a build prompt that recreates it, so you can reuse it, share it, or rebuild it with a different model.

With the nnuer connector, Claude can:

• Send the UI you just built to nnuer, split into blocks. Each block includes its build prompt, the React or HTML code, and any images it uses. The code is checked before anything is saved. If something fails, Claude gets the error and can fix it and send again.
• Search public blocks or your own library by keyword and category.
• Fetch a block's build prompt and code, so you can assemble new pages from blocks you or others have made.

Nothing is published automatically. Blocks Claude sends wait in your review inbox. You preview them, choose which to keep, and set their visibility (private, link only, or public) on nnuer.

Tools:

• get_block_guidelines (read-only): block categories, code format and how to write a build prompt
• submit_blocks (write, non-destructive): send blocks to your review inbox
• search_blocks (read-only): find public blocks or your own blocks
• get_block (read-only): get one block's build prompt and code

Sign-in uses OAuth with your nnuer account. You can disconnect anytime in Settings > AI tool connections, which revokes access immediately.
