Cool names and indica vs sativa don't predict your high. AI deep research and real terpene science do — for every strain, every time.
Plant type doesn't predict your high. Chemistry does. We map every strain's terpene profile and sort it into one of 6 High Families, patterned on the six terpene clusters found in a 2025 peer-reviewed study of 140 flowers.
And the biggest number on the label? THC% tells you how strong. Terpenes tell you how it feels. A percentage measures one batch from one grower — a volume knob, not a description of the experience.
Go beyond sativa, hybrid, and indica. Choose from 6 terpene-based High Families. Tap a face to peek inside.

Tap a question to hear the answer.
Their THC is close: Jack Herer lists 21.5% and Granddaddy Purple lists 20.5%. The terpenes are not. Jack Herer's dominant terpene is terpinolene, and its record lists Euphoric, Uplifted, and Creative. Granddaddy Purple's is myrcene, and its record lists Relaxed, Sleepy, and Euphoric. THC sets the strength. Terpenes shape the ride.
Sort of. Blue Dream is sold as sativa-dominant, and its record lists a 60% sativa / 40% indica mix. But its dominant terpene is myrcene, the same as OG Kush, a hybrid. That is why the label alone cannot predict a high. Read the terpenes.
Start with the Relaxing High family (deep body calm). Its strains lead with myrcene, the terpene that goes with a slow, easy feel. Try Blue Dream, Granddaddy Purple, or Strawberry Cough. Start with a small amount and go slow.

Short answers on the High Families, how we research strains, and what the scanner and the app do.
High Families are 6 groups of strains sorted by their terpene profiles instead of the indica, sativa and hybrid labels. They describe how a strain tends to feel. They are based on a 2025 peer-reviewed study that analyzed 140 strains across 9 key terpenes, which explained 86% of the chemical variation.
An automated AI research pipeline gathers data from multiple sources, checks terpene and cannabinoid profiles, and places each strain in a High Family. We track 22,660 strains, and 3,080 of them have finished the full research pipeline. Any other strain can be researched on demand from its own page, usually within minutes. Profiles are refreshed as new lab data appears. No sponsored strains, ever.
Take or upload a photo of a cannabis product label or COA (certificate of analysis). AI research reads the terpene data and THC and CBD percentages, then places the product in its High Family. Images are processed and never stored.
Hundreds of strains have their own song, generated from the strain’s terpene profile and effects. Myrcene-heavy strains get slower, relaxed tempos; limonene-heavy strains get brighter melodies. New songs are added as more strains are researched.
