Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based tool for pinning notes to exact spots in PDFs and preparing those references to paste into an AI chat.

Landing page captured for the 2026-10-06 issue.

For: Readers reviewing PDFs with AI assistants
Worth noticing: Each numbered heart exports the page and underlying text; figures and scanned pages use position instead.

Field notes

The note combines general comments with numbered references, and the export includes each marker’s page and nearby text when the document provides it. On figures and scanned pages, the reference falls back to position; PNG and JPEG users can also copy an image with its markers drawn on. The page says a JSON save stores the note and marker positions, not the original PDF or image.
