Second Brain for AI
I don't just build Second Brain. I use it every day.
Today I stored every comment, every piece of feedback you all left on the launch. Then asked it to tell me what v3 should focus on. That screenshot is the answer.
Top 5 on Product Hunt. Honestly didn't see that coming.
Thank you. Every comment, every upvote, every share, it's what makes building this worth it. You're not just users, you're shaping what this becomes.
v3 is already taking shape because of you.
