Notestark Notes — Highlight Local Markdown & the Web

Highlight and underline local .md and .html files — your marks survive closing the tab.

Mark up what you read the way you would mark up paper. Select text, pick a color or an underline, and it stays. Close the tab, restart the browser, come back a week later - the marks are still there. WORKS ON YOUR OWN FILES, NOT JUST THE WEB Most highlighters only reach web pages. This one also works on documents opened straight from your disk: local .md and .html files, exported documentation, README files, API references, runbooks and specs. That is the reason it exists. If you read technical documentation offline, nothing else covers it well. READ MARKDOWN AS A DOCUMENT, NOT AS SOURCE Chrome shows a local .md file as a wall of plain text. Notestark renders it — headings, code blocks, lists, tables, quotes — and one button in the panel switches back to the source whenever you want it. The renderer is part of the extension. Nothing is fetched to draw your file, and no third-party code runs on it. SIX COLOURS, PLUS UNDERLINE — AND THEY COMBINE Yellow, green, pink, blue, orange, purple, and a separate underline. A passage can be yellow AND underlined; pressing one never clears the other. Press the same thing again to remove it. The palette was chosen by measurement, not by eye: every color keeps text at WCAG AAA contrast, and the colors are kept apart in brightness so they stay distinguishable under color vision deficiency. You can change any of them, and the contrast is shown as you pick. You can also name your colors — one label per color, shown wherever that color appears. Six unnamed squares only say "these are different"; a name says which one is questions. Each swatch carries the first letter of its name, drawn in ink computed from that color's own brightness so it stays readable on a light or a dark fill. MARKS SURVIVE THE DOCUMENT CHANGING Each highlight remembers the exact text plus the words around it. When a document is edited and the passage moves, the mark is found again by matching that context. If the text is deleted, the highlight is not thrown away — it simply waits, and returns if the text comes back. Renaming or moving a local file does not lose your marks either. REQUIREMENTS AND LIMITS • Chrome 105 or newer; translation needs Chrome 138 or newer on desktop • Chrome does not let any extension work on chrome:// pages, the Web Store, or other extensions' pages • Tags do not exist yet • Some single-page applications rewrite their address after loading, which can make a mark harder to find again
