I type in two languages and very frequently I don't notice that I am on the wrong layout, so I get a full line of gibberish before I notice. Got annoyed enough to build something. It keeps the right language ready per app and per browser tab, and if you mess up you double-tap Shift and it fixes the last thing you typed. I know layout switchers aren't new. The thing I couldn't find is that it remembers the language per browser tab and per chat on Teams (I work with a mix of English and Hebrew speakers), not just per app, so it sets the right one before you start typing. And when it still gets it wrong you fix it with one shortcut instead of letting an auto-detector guess for you. It's free (pay what you want) and everything stays local, no account. Not pushing anything, I just want to know if it's useful and what's missing. I'd appreciate any feedback!! Site's here (with a demo...) : https://flickey.site
