Build native OS integrations that work everywhere rather than another standalone app
Instead of building yet another app users must switch to, integrate your tool at the OS level so it works within every application the user already uses. This eliminates context switching and makes your tool feel like a superpower rather than another tab to manage.
When to use
When building productivity or writing tools where users work across many different applications and context switching is the core friction
Don't do this
Building a standalone web app or separate interface that requires users to copy-paste between your tool and their workflow

Built Elephas as a Mac-native app accessible via keyboard shortcut in any application, rather than as a browser-based AI tool. Deep OS integration enabled AI superpowers across email, docs, social media without switching apps.
