We have developed phone-based AI technology which is able to detect with our $1 phone attachable magnifier any pest, plant disease or mineral deficiency. Farmers in Africa, Asia and Latin America do not have access to agronomy advice. We can provide high-quality free agronomy advice sponsored by companies that purchase from farmers or sell inputs to them. This will reduce the inappropriate use of chemicals and make farming more profitable for subsistence farmers – who can also get better and fairer pricing by using our apps to QC their produce.
