Extracting Text From Images Using Ruby

I’m a great hoarder of memes. Seriously, I have a huge folder full of memes and GIFs. I collect my memes usually whenever I’m watching a movie or a series by taking a screenshot of the scene with subtitles enabled. The issue is, the program I use to take screenshots, names each new file by the date and time the screenshot was taken. I have a 1200 screenshot folder each named by date and time. So finding a certain screenshot/meme is too much a hassle.
