Highlight Keep — Web Highlighter & Notes by gio

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 (Obsidian, Notion, anything).
• PDFs on the web too: open one in the built-in viewer page from the popup and highlight it like any page.
• Per-site switch: on for the sites you read on; 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. One key for every browser; works offline; 14-day refund.

Private by design: no account, no sync server, no data collection. The only request it ever makes is a one-time check when you activate a paid key.
