Mac: You have a ton of great launchers on Mac and even the built-in Spotlight does a good enough job for most of us. If you’re looking for something a little different, Lacona is an app currently in beta that takes a natural language input approach.
At its core, Lacona isn’t terribly different from an app like Alfred, but it allows for a different type of command type. Once you open it up with a keyboard shortcut, you can use commands like, “switch to Chrome” to switch apps, or “open lifehacker.com in Safari”. You can also use it to set up reminders with commands like “remind me to pick up cat food tomorrow at 8AM”. You’ll find a ton of different example commands over on the developer’s site. It’s still very much in beta so of the integrations don’t work as expected, but it’s worth playing around with now while it’s in beta, especially if you haven’t had much luck getting used to other launchers.
