About

Adnota turns your browser into a canvas: The Eraser: Click on any annoying: ad, popup, or sidebar and delete it. The best part? It stays deleted even if you refresh or come back tomorrow. The Highlighter & Notes: Mark up text and drop sticky notes directly on the page for your research or AI prompts. The Resizer: Drag and drop or resize cramped layouts. Absolutely private. No cloud, no telemetry, no accounts. Everything saves locally to your browser. It’s also 100% open-source (MIT licensed)...
