Actually, it can do a fair bit of the voice assistant stuff now. It’s a bit more janky than off the shelf solutions, but it can be done. It was their big push this year with the “year of voice”.
There is also the new AI response button. But not everyone sees that. I think that’s the biggest reason for this change. It looks better than the couple other ways they demoed the ai smart reply ui.
It might be that you’ve heard of the alternative client, Runelite. This is still osrs on the same servers. It is just a different client with more bells and whistles. I highly recommend it! You can even launch it directly from the jagex launcher now.
