PageNote is a Chrome extension that lets you attach a note to any URL. Open the page again, even weeks later, and your notes are right there waiting. No separate app to open, no filename to remember.

## Notes for competitor and landing-page research

It’s built for the kind of research workflow marketers and researchers run every day: comparing a handful of competitor sites side by side, tracking how a campaign landing page changes over time, or just remembering “I already looked at this and decided X” the next time the same URL comes up in a different context. The note-taking habit is one click on the same toolbar icon regardless of which site you’re on, so it doesn’t compete for attention with whatever tool you’re actually using to do the research.

## Why per-URL, not a separate app

A dedicated notes app means switching windows and re-establishing context from scratch: which tab was this about, what was the note referring to. Pinning the note to the URL itself keeps the note and the evidence for it in the same place, since the note only really makes sense next to the page it’s about. Revisit the URL later and the context comes back with it automatically, with nothing to search for across a separate notes archive. It also removes a small but real daily decision (“which app do I open for this”) since the answer is always the same regardless of what site you’re currently looking at.

## No accounts, no sync, no telemetry

Standard Chrome extension setup: content scripts handle the on-page UI, and the Chrome storage API persists notes per URL locally. The surface area stays deliberately small: it doesn’t create accounts, doesn’t sync across devices, and doesn’t send telemetry anywhere. The tradeoff is explicit: notes stay on the machine where you wrote them, in exchange for a tool that has nothing to leak and nothing to sign into.
