# What is llms.txt? > llms.txt is a proposed Markdown file at a website's root that gives AI assistants a short, curated guide to the site. Learn the format and its limits. Canonical: https://www.notchstar.com/glossary/llms-txt/ Last updated: 2026-11-04 Published 2026-11-04. llms.txt is a proposed Markdown file that gives AI assistants a short, curated guide to a website. It sits at the site root, as `/llms.txt`, and points to the pages that matter, often as clean Markdown. It was proposed by Jeremy Howard of Answer.AI, first published on 3 September 2024. ## The format The one required element is a heading with the project name. After it come an optional short summary in a quote block, optional paragraphs, and sections of links, each link with a short description. A section named Optional holds links an assistant may skip when it needs less context. ## Why it matters A model that reads a page has to wade through navigation and scripts. A curated list helps it find the right page quickly. It is a proposal, not a standard that every assistant follows, so treat it as a courtesy and not as a promise that any assistant reads it. ## On notchstar.com The site serves `/llms.txt`, and a longer `/llms-full.txt`. They list the product, the features and the comparison pages. They state the same facts as the rest of the site: $4 once, macOS 14 or later, up to three Macs. Prices as of 4 November 2026. ## Related For what an assistant would find, see [the best Mac notch apps](https://www.notchstar.com/guides/best-mac-notch-apps/) and [is NotchStar safe](https://www.notchstar.com/guides/is-notchstar-safe/).
