An interesting service. In short, it allows you to parse users from VKontakte and create databases for retargeting in txt format. To elaborate, it’s a whole set of scripts with extensive capabilities. For example, you can gather an audience from a specific public page or do something more complex: collect data from 100 public pages, conduct a cross-search to select people who are subscribed to 3-4 of them, who like posts from a particular individual or community, and are friends/subscribers of a specific person. The accuracy of the settings is truly impressive. Overall, if we talk in general terms, it has the typical functions of any parser: searching for the audience of a specific channel (public page, person, etc.), parsing by activity, the ability to parse subscribers from multiple communities simultaneously, finding similar communities, and comparison – this service makes it convenient to create intersections, remove duplicates, and so on. All work is done in the browser, so if any issues arise, such as slow parsing, it’s not always related to the service itself. Most often, it's about the hardware, and you should pay attention to the RAM. Processing depends on the power of the computer: the higher it is, the faster the work goes. But, to be honest, the algorithms could be written better. I have a decent i5 and 8 GB of RAM, and I can't say that parsing happens very quickly. Therefore, for owners of weak and mid-range hardware, the service may not be suitable in terms of performance. Yes, familiar cloud tools will work faster. But considering the possibility of free use – I have no complaints. It fulfills its purpose, filters the audience – I have no issues.
