Hey all, The original motivation for making this app was that I wanted to make a simple and powerful tool to help everyone research into the companies they are vested in -- one that should be mobile friendly where any one can take a quick look (during lunch or a walk) and gain insights on the companies they care about. If you are interested in this idea, please try out the app and let me know what you think!

Cool app! Where do you get your data from?

@lrueger I download earnings pdfs from each company’s website and use machine learning to extract the data :)

Congratulations on the launch. You mentioned using data from the network for training, okay. Can you tell me about the predictive models used in your application? For example, earnings + the forecast that is generated. How can your application assist in decision-making?

@kostyadoronin I trained my own natural language processing (nlp) model through ner, annotations and such and simply tested on several different types of pdfs to make sure the output is correct. If it’s not correct, I’d correct the model to make the model stronger. Rinse and repeat. :)

I like the idea behind this. Curious though, why a mobile app? It feels like this could get a lot of use if ppl didn’t have to install something.

@valsk Thanks for asking! The season is that I wanted to specifically make something that looks great on mobile. I find most similar products I tried tend on the website experience — sometimes they don’t look that great on mobile. And if I want to pull up a chart on a phone, I’d still have to go open the browser and enter the url. Having a mobile app ready just makes things more convenient for me personally, and hopefully it’s more convenient for you too :)
