Highlight Keep — Web Highlighter & Notes, Private

Mark what matters, and keep it. • Highlight any text on any page — it's there again next visit, anchored to the words, so it survives the page changing. • Click a highlight to change its colour, add a note, or remove it. • Copy a page's highlights as Markdown (works with Obsidian, Notion, anything). • Per-site switch: turn it on for the sites you read on (Alt+Shift+H); it never runs anywhere else. Unlock ($12, once): unlimited sites, six colours, notes and tags, the library — search everything you've kept, export it all, backup and restore as a file. One key for every browser you sign in to; works offline; 14-day refund. Private by design: no account, no sync server, no data collection. Highlights and notes live in your browser's extension storage. The only request it ever makes is a one-time check when you activate a paid key. Made for students, researchers and anyone who reads for a living.
