The lesson
Follow your launch line with the objection your audience already holds, and answer it in a short sentence.
The post reads "Notion AI is now available to everyone. No waitlist, no "limited preview." Get started: notion.ai". Above it a product video frame shows a dark page titled "Executive presentation", a comment from Maya Jones, "Deadline changed...", and a "To do:" list. The preview card says "Notion AI is here, for everyone".
Don't copy the line if your launch is gated, and don't lean on the reaction count shown, which says nothing about why it got there. Keep the stated anti-objection and a task-sized demo.
