Methodology

How Matchleaf Works

Matchleaf is a decision tool, not a catalog. You bring the strains you have — whatever is available to you — and tell it what you want to feel. It matches the two using terpene science.

The Matching Process

1

Enter your available strains

Type or paste the strain names from whatever you have — a dispensary menu, a home stash, a friend's options. Matchleaf also accepts photos of menus: take a photo, upload it, and the tool extracts strain names automatically using OCR.

2

Select your target effects

Choose from 10 effect categories. Select multiple to get separate, independent recommendations per effect — not a single compromise strain. Each effect lane returns its own ranked list.

3

Get ranked recommendations with terpene reasoning

Matchleaf scores each strain against your chosen effects using its terpene and cannabinoid profile, ranks them by fit, and explains the mechanism behind each pick. Strains in the database are matched instantly; unknown strains are analyzed in real time.

How Scoring Works

Each strain in the Matchleaf database carries a terpene profile and a 10-point effect score for each of the 10 effect categories. Scores are derived from terpene pharmacology research, strain lineage, and cannabinoid ratios.

When you select an effect, Matchleaf ranks your available strains by their score for that effect. A strain scoring 8–10 on Sleep has a dominant terpene profile — typically high Myrcene and Linalool — with documented sedative associations. A strain scoring 2 on the same effect is deprioritized for that lane regardless of its overall popularity.

For strains not yet in the database, Matchleaf falls back to real-time AI analysis. The output is the same — ranked picks with terpene reasoning — but generated on the fly rather than retrieved from stored profiles.

Terpene Weighting

Terpenes are the primary signal in Matchleaf's scoring model, weighted above cannabinoid content. Terpene profiles are more consistent across batches than THC percentage, and terpene pharmacology provides a mechanistic basis for effect prediction that the indica/sativa binary does not.

The dominant terpene by concentration receives the highest weight. Secondary terpenes contribute additive signals. Cannabinoid ratios apply a modifier — high THC amplifies effects; CBD moderates them. Advanced filters let you boost or suppress specific terpenes in your results.

The 10 Effect Categories

Each category maps to a distinct use case and a set of terpene signals. These are informational descriptions — not medical claims.

EnergizingUplifting and active. Associated with limonene, terpinolene, and pinene.

CreativeDivergent thinking and ideation. Often driven by terpinolene and limonene at moderate THC.

EuphoricMood elevation and happiness. Strongly linked to high THC and limonene.

Sexual AmplificationSensory enhancement and arousal. Associated with limonene, linalool, and vasodilatory terpenes.

RelaxingBody and mind ease without heavy sedation. Myrcene, linalool, and caryophyllene.

SleepSedation and sleep onset support. High-myrcene strains with linalool.

Pain ReliefPhysical discomfort reduction. Caryophyllene (CB2 receptor agonist), myrcene, and humulene.

SocialLowered inhibition and conversational ease. Limonene with moderate THC; low-myrcene profiles.

FocusConcentration and mental clarity. Pinene, low-myrcene profiles, balanced THC:CBD.

AppetiteHunger stimulation. Myrcene and high-THC strains with CBG.
