Hello.

During a trip to Llangollen, I noticed that the historical information on local signs wasn't available online. This sparked an idea to make such information accessible on the web, especially for those with reading difficulties. I experimented with my existing image text extraction tool and found it works surprisingly well on these types of images. I'm now considering creating a website dedicated to archiving and indexing the text from informational signs, inspired by Google's Navlekhā project which helps offline Indian publishers digitize their content.

I built a Progressive Web App (PWA) that extracts text from images shared to it. It uses the Share Target API to receive images, the Shape Detection API's TextDetector to analyze them, and EXIF-Js to handle image rotation issues. While it's a handy tool, it currently suffers from cross-browser and cross-version compatibility problems due to the lumpy nature of the web platform. The code snippets highlight key implementation details, like manifest setup, service worker handling, text extraction, and image rotation.
