Beacon - Turn highlights into webpage navigation markers

Hi Product Hunt 👋 I built Beacon because my online research workflow became faster with AI, but also much messier. When I use ChatGPT, Gemini, technical docs, or long articles to learn something, I constantly run into new concepts I want to revisit later. I don’t always want to save everything into a note-taking app. Sometimes I just need a lightweight way to mark important parts of the current page and jump back to them instantly. That’s what Beacon does. Select text, use a shortcut, and Beacon creates a highlight plus a small clickable marker on the right edge of the page. The marker reflects where the highlight appears in the content, so the page becomes easier to navigate. It’s useful for: long articles AI-generated answers technical documentation API references online research reports study materials knowledge-heavy webpages Beacon is intentionally simple. It does not try to replace full note-taking or knowledge management tools. It focuses on one small workflow: helping you return to important passages without losing your reading flow. This is v1.0, so compatibility may not be perfect across every webpage layout yet. I’d really appreciate feedback, bug reports, and ideas for what should come next. Question for the community: When you highlight content online, do you mainly want to save it for later, organize it into notes, or navigate the current page faster?
