Transparent, Convenient, Collaborative Catalytic Converter Recycling App. Catalopedia is a catalytic converter encyclopedia with unlimited free searches to find the exact converter you are looking for. We offer a transparent pricing system, where you can choose your own return rates and other settings and customise the app to your personal requirements. We provide very accurate catalytic converter prices, our metals and FX prices are updated hourly. Our images are 3D rendered and all pictures are digital with exact measurements. Our sampling and analysis systems are refined, with processes to eliminate machine, human error and we do 6 analyses at minimum based on tolerance and deviation criterias to determine the final analysis before publishing on the app. Therefore, the analysis which can be purchased is extremely highly reliable. We differentiate the products by country, as you will realise converters with identical markings have differing analyses, therefore different prices, if they originate from different countries, due to their emission standards. We also have other means to filter the converters to dwindle down the searches. Test our Beta Identify feature. We render several thousand images of different backgrounds, simulating rust, dents etc from our 3D images. Then we feed them to our own AI neural network engine. This engine is able to learn and guess what you are looking for by shortlisting it. It however only works for models in our catalogue and we are training it every day, as we add products. So in the testing phase, it's completely free. We have a highly collaborative mindset. We have a good application, but our products are very limited to a few countries. If your country’s products are not covered in the application, we would be happy to discuss with you and obtain samples to include them in the app. We are also looking for franchise partners who want to be part of our application. We are more than happy to collaborate and share the benefits.
