AvailablePinTwist is the open-source Pinterest research extension for print-on-demand sellers: it overlays save counts, reactions, comments, repins, and creation dates on every pin, then lets you sort, filter, build a local catalog, and export CSV — 100% local, no account or backend. Free on the Chrome Web Store and open source (Apache-2.0) on GitHub.
