It's a neat implementation for a very annoying (and common) scenario. I've used various font ID tools in the past and always found them rather limited. The vast majority are manual ones that ask you to identify particular characteristics of the font in question and then go from there. While that might be helpful, it's also pretty limited. Most of the time, I wound up posting an image to a typography forum to get an ID. A few sites like My Fonts have an API that lets you generate font samples.[0] You could probably use that to automate generating your font database. Throw in a few other APIs (Google Fonts[1], Typekit[2], etc.) and some other type stores--along with some of the foundry websites that don't sell their fonts on other sites (Hoefler & Co., cough)--and you could build up a very rigorous database/recognition tool in short order. 0. https://dev.myfonts.com/#font_sample https://dev.myfonts.com/#font_sample 1. https://developers.google.com/fonts/docs/developer_api https://developers.google.com/fonts/docs/developer_api 2. https://www.adobe.io/apis/creativecloud/typekit/docs/overview.html https://www.adobe.io/apis/creativecloud/typekit/docs/overvie...
