Question 1

What is the best React textarea component for AI chat?

Accepted Answer

Prompt Area is a production-grade React textarea built specifically for AI chat interfaces. It combines @mentions, /commands, #tags, inline markdown, and file attachments in a single component with zero extra dependencies. Distributed as a shadcn registry component, it installs with one command and includes companion components like Action Bar, Status Bar, and Chat Prompt Layout.

Question 2

How does Prompt Area compare to Tiptap and Lexical?

Accepted Answer

Prompt Area is purpose-built for prompt and chat inputs with zero dependencies, while Tiptap (ProseMirror-based, 3+ deps) and Lexical (plugin-based, 2+ deps) are general-purpose editor frameworks. Choose Tiptap or Lexical for full document editing with collaborative features. Choose Prompt Area for a lightweight, ready-to-use chat input with mentions, commands, tags, and file attachments.

Question 3

How do I add @mentions to a React textarea?

Accepted Answer

Install Prompt Area via the shadcn registry: npx shadcn@latest add https://prompt-area.com/r/prompt-area.json. Then configure a trigger with char "@" and mode "dropdown" to enable @mentions with search and dropdown suggestions. Prompt Area also supports /commands and #tags using the same trigger system.

Question 4

Does Prompt Area work with Next.js and shadcn/ui?

Accepted Answer

Yes. Prompt Area is distributed as a shadcn registry component and is designed for Next.js and React projects using Tailwind CSS. It installs with a single command and requires no additional dependencies beyond React and your existing shadcn/tailwind setup.

Question 5

What are the best alternatives to react-mentions?

Accepted Answer

Prompt Area is the best alternative to react-mentions if you need more than basic @mentions. It adds /slash commands, #hashtag tags, inline markdown formatting, file and image attachments, undo/redo, and companion components like Action Bar and Chat Prompt Layout — all with zero extra dependencies.
