We use Notion like crazy internally so it was at the top of our priority list along with Slack. I probably paste 80% of my links into Slack... it's magical b/c people just watch, get the context and then discuss... I hate information dumping and Grain + Slack saves me tons of time to share video highlights instead and they work better anyway b/c it preserves the context and richness of the original video (with voice, tone, facial expressions, screenshare content, etc.). All of those get lost when trying to summarize a video call to info transfer to someone else.

I find myself pasting Grain highlights in Notion when I'm doing more analytical work that I want to be supported by rich media/evidence and become a source of reference/documentation. Think highlight reels.
