Will It Layer?

What it does

Everyone is talking about fragrance layering. Nobody seems to know what actually works. WillItLayer.com uses AI to analyse how two scents interact - from note structure to dry-down - then returns a compatibility score and exact application guidance (order, placement, ratio). Users can register and upload their shelf (via AI vision) to find combinations or generate new pairings from a single fragrance.

Will It Layer? is a free AI-powered fragrance layering tool — enter any two perfumes and get an instant compatibility score, note breakdown, and layering tips.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
