Pieced Together - what could an advertiser piece together from your inbox?

Paste up to 40 sender and subject lines from your own inbox. Free in the browser: addresses, links and long numbers are redacted before anything leaves the page, each line becomes a jigsaw piece, a quick keyword guess groups them, and you can pull pieces out to watch the picture blur. One metered task reads the lines the way an ad system would: every line placed in an interest group or left loose, the picture rated open book, half done or a few pieces, sensitive groups flagged, and for each group what it gives away, the ad that would follow and one way to hide it; the page re-checks the reply. A playful privacy check, not privacy or legal advice. Built on @aaron-he-zhu/audience-mapper.
