Arc: llms.txt vs Fontio ‑ Easy Font Changerfor Shopify (2026)
Arc: llms.txt and Fontio ‑ Easy Font Changer both fall under the 'Content' category on Shopify, but address entirely different needs. Arc: llms.txt focuses on optimizing a store's visibility for AI models like ChatGPT, Claude, and Gemini through the creation of an `llms.txt` file – essentially a specialized sitemap for AI crawlers. Its strength lies in its automated, one-click approach, targeting merchants who are keen on staying ahead of the curve in AI-driven search and shopping.

Common Questions
Does Arc: llms.txt affect my store's loading speed?
The app description suggests automated hosting and refreshing of the llms.txt file, implying optimization. However, the exact impact on loading speed isn't specified and would likely be minimal as llms.txt is a small text file.
Can I use Fontio to upload custom font files?
The description mentions 'Custom fonts' but doesn't detail the upload process. Further research would be needed to confirm if Fontio supports font file uploads directly, or if it requires links to hosted font files.
Is it possible to customize the content of the `llms.txt` file generated by Arc?
The description emphasizes 'one-click generation' and 'auto-creates,' suggesting limited or no manual customization options for the `llms.txt` file's content beyond what the AI automatically determines.
How often does Fontio update its font library?
The description doesn't provide information about font library update frequency, but as it relies on Google Fonts, the library is likely updated regularly with Google's font additions.
If I uninstall Arc: llms.txt, what happens to my `llms.txt` file?
Presumably, uninstalling Arc would remove the hosted `llms.txt` file. You would need to create and host one yourself to maintain AI visibility.
