Arc: llms.txt vs Kodexfor Shopify (2026)
In 2026, both Arc: llms.txt and Kodex aim to help Shopify merchants improve their content and SEO, specifically related to AI-driven search. However, they differ significantly in their current state and approach. Arc: llms.txt focuses on generating and maintaining an `llms.txt` file, explicitly designed to improve visibility for Large Language Models like ChatGPT, Claude, and Gemini. Its key strength lies in its one-click setup and automatic refresh functionality, targeting merchants who want to easily optimize their store for AI-powered search and conversational commerce. Kodex, on the other hand, currently lacks any user reviews or specific feature descriptions. This absence of information makes it difficult to assess its value proposition or target audience. Given the provided data, Arc: llms.txt is a far more established and demonstrable solution for merchants seeking to leverage AI search optimization. Its existing user reviews and clear feature set make it a less risky and more immediately beneficial option.
