The UX Writing Assistant is a powerful plugin that uses AI to provide copy suggestions for your design team. It includes features like AI copy suggestions, integration with your design system for consistency, and streamlined design reviews to save time and increase productivity. It's geared for product and content designers working in Figma, with different pricing levels for teams of different sizes and needs.
Another good option is UIQuill, which offers AI-generated text based on your Figma designs. UIQuill's context-aware suggestions are optimized for purpose, style, tone and length so you can quickly create high-quality content. It also offers multilayer optimization and SEO-optimized text. It offers monthly and lifetime subscription plans.
For a plugin that handles more general writing assistance, TextWise offers translation, paraphrasing and creative copy generation within Figma. It includes an AI Translator for more than 30 languages, an AI Paraphraser and an AI Writer. The idea is to boost productivity by automating writing tasks so you can focus on design work.
