Roast analysis powered by Gemini AI. Grind detection that reads your coffee's soul. A community of obsessives who refuse to settle for average. This is RoastLab.
Every great cup starts with a single variable. Temperature. Grind size. Roast level. Most people guess. You don't have to anymore.
RoastLab brings the precision of a professional cupping lab to your kitchen counter. Point your camera at any bean. Our Gemini AI engine reads the Agtron roast score, predicts flavor compounds, and tells you exactly how to brew it.
This is not a coffee app. This is a coffee intelligence system.
"Every bean tells a story.
AI just learned to read it."
Each feature is engineered for the person who refuses to brew a mediocre cup.
Point. Shoot. Know. Our Gemini-powered vision model reads roast colors, estimates Agtron scores, and detects grind particle distribution in seconds.
