But for some reason, they decided to just stick to feature tidbits here and there and chose not to roll out quality-of-life UI features to make Gemini use easier on normal apps and not just select Google apps. And then it's also limited by various factors. They were obviously testing the waters and were just as cautious, but imho it was a damn shame. Even summarization and key points would've been nice if I could invoke it on any text field.
But yeah, this is truly the ecosystem benefit in full force here for Apple, and they're making good use of it.
