See every featureMost AI content tools just connect to ChatGPT and call it a day. Parallax is different. We combine industry-leading LLMs with proprietary algorithms developed by SEO and e-commerce experts, delivering conversion-focused content that AI alone can't achieve. Optimize meta titles, descriptions, and full product content across your catalog with ease.
Most stores have hundreds of products with blank or weak search metadata — invisible on Google. SEOnix uses AI to write a search-optimized meta title and meta description for every product, in bulk. Titles stay under 60 characters with your main keyword; descriptions under 160 with a clear call-to-action. Review every change before it goes live, undo anytime from full history, and clear old SEO in one click.
