The Anatomy of a Cannabis Recommendation: How StrainBrain Simplifies Discovery and Drives Sales

Navigating a cannabis menu shouldn't feel like decoding a lab report. Yet, that's exactly what most customers face when they shop online or in-store. Whether they’re curious first-timers, wellness seekers, or seasoned connoisseurs, consumers often hit a wall of confusion: terpene charts, THC percentages, and quirky strain names that offer little context. That friction costs retailers millions in lost conversions.

StrainBrain was built to remove that friction.

Starting at the Entry Point: Different Personas, One Common Denominator

Consumers enter the cannabis journey from vastly different starting points. Some are novices with limited vocabulary, unfamiliar with the chemistry of cannabis. Others are seasoned users with established routines and preferences. Yet, the least common denominator between them all is the question: "How do you want to feel?"

This is where StrainBrain begins. Instead of overwhelming the consumer with technical terminology, we use simplified and tested questions that act as proxies for the science underneath:

• "How do you want to feel?" = Proxy for cannabinoids (e.g., THC, CBD, CBN)
• "How do you want it to taste?" = Proxy for terpene profiles (e.g., citrus, pine, earthy)
• "How intense do you want the experience?" = Proxy for dosage and form factor (e.g., 5mg edible vs. 1g pre-roll)

These intuitive questions help us map complex chemistry to human language, creating a smoother entry point for all types of users.

At the core of every recommendation is a sophisticated, science-driven process powered by OWL, our Optimized Weighted Language AI model. It is the first domain-specific recommendation engine built specifically for cannabis, and it's why retailers using StrainBrain see basket sizes jump by $11.50 or more.

Step 1: Understanding the Inventory

We start by characterizing every product in a dispensary's menu using a unique scoring methodology. StrainBrain analyzes attributes like:

• Primary and secondary effects (e.g., euphoria, focus, relief)
• Flavor and terpene expressions (normalized across vendors)
• Onset time, duration, and intensity (especially for edibles)
• Form factor: flower, vape, edible, topical, tincture, etc.
• Verified availability based on the retailer’s live ecommerce feed

StrainBrain’s AI Budtender is powered by a proprietary Optimized Weighted Language model (OWL). The database has been built over four years, sourcing from brands and producers, dispensaries and retailers, and consumer information. Industry references such as leafly/nuggmd, and open source databases provide insights into feelings, tastes, and experiences. Reviews on sites such as reddit fill out additional information on effects, negative effects, and the progression of an experience. Dispensaries can create profiles for new products and strains so that the database is always up-to-date and immediately able to recommend any product in inventory. 

Step 2: Capturing the Consumer’s Intent

Our AI Budtender engages the consumer with just a handful of questions, never more than needed. Through that short interaction, we collect 6-7 data points about the customer:

• Desired effect or outcome (e.g., "I want to feel relaxed")
• Preferred product form (flower, vape, edible, etc.)
• Flavor preferences
• Sensitivity level (optional)
• Experience level or familiarity

From this, we generate a "desired product profile," scored across the same dimensions as our inventory.

Step 3: Matching with Cosine Similarity

Once the customer profile is built, StrainBrain applies a cosine similarity algorithm to identify which products most closely match the consumer’s desired outcome. This approach compares the angle between two multidimensional vectors (desired profile vs. product fingerprint), prioritizing closeness in effect and form over raw chemistry. 

For example, if a customer wants something uplifting and social in edible form, StrainBrain might rank a 10mg sativa gummy at 92% similarity, while a hybrid tincture could score 75%. Rather than defaulting to generic labels “sativa” — which can vary widely in actual effect — StrainBrain calculates the true match based on desired outcomes. 

Step 4: Real-Time Results, Real Inventory

Unlike many solutions that rely on batch-specific COAs or static menus, StrainBrain validates its recommendations in real time against the retailer's e-commerce feed. That means no recommending out-of-stock products. We prioritize what's available now, which is critical in a high-turnover industry.

Step 5: Reducing Friction and Building Trust

By focusing the experience around how someone wants to feel, we eliminate the need for a customer to understand cannabinoids, terpene maps, or confusing strain names. And with each use, our system gets smarter. Over time, we plan to deepen personalization by incorporating user history, purchase behavior, and even persona-level segmentation (e.g., "55+ wellness users") into the match logic.

This creates a virtuous cycle: better recommendations lead to faster decisions, higher conversion, and more data to improve the system.

Final Thoughts

StrainBrain isn't just AI for AI's sake. It’s designed to support the entire cannabis shopping journey, helping retailers serve more customers, more effectively, more of the time. Because at the end of the day, the best recommendation isn’t the one that’s scientifically perfect. It’s the one that helps someone feel understood and excited to come back.

And that’s exactly what StrainBrain was built to do.

- Small Language model  

- Normalizes conversation across multiple segments

- Unlocks opportunity to bring new customers with less friction

- Can be applied toward other verticals
