Overview

• Malte Bayer from Lahr discovered the tiny sealed bottle at Hörnumer Odde on Sylt in 2018 but could barely read the waterworn letter.
• He used three to four tools, including ChatGPT and image enhancement, to process photos of the paper and reconstruct the handwriting.
• The analysis named the sender as Linda, dated the message to 20 October 2007, and gave the address 5 Roslyn Crescent, Reading, England.
• From handwriting and phrasing, the system estimated the sender’s age at 11 to 16 and inferred a likely route via the Thames estuary and the North Sea to Sylt.
• Bayer has not located the sender or confirmed the details, and an AWS technologist notes such AI reconstructions offer leads that still need human verification.
