DataFan

DataFan positions itself as an analytics bot for your social media presence broadly, with Telegram channel analysis as one part of that: ask it about your channel or a competitor's and it reports back what it can determine about audience and performance, plus advertising-campaign effectiveness metrics.

Because it spans multiple platforms rather than being Telegram-only, it suits marketers who track a channel alongside other social accounts in one place, more than an admin who only cares about one Telegram channel in isolation.
