Which is extra frustrating because I recall reading a Microsoft apology about how they could not easily add support for different line endings to Notepad. The software is so entrenched that they are terrified to edit it. Which, fine, maybe that is sort of justifiable, but seems like something that Microsoft has the resources to test.
A few years later, AI slop gets embedded into everything, reasonableness or performance be damned (the new Notepad is embarrassingly slow to launch with multiple visual glitches).
Apple added it as a system-wide service available in any text field. There isn't a dedicated button and branding for it within TextEdit. It's there because it's runs inside macOS.
No this is not a joke. Notepad has a giant always-present Copilot button now
