Finster is a research tool for investment banking and asset management. The distinguishing requirement in that setting is not capability but confidentiality: a bank cannot put live deal material through a general assistant, so the useful product is the one built around private, controlled data from the start.
It is positioned as proactive rather than purely responsive, surfacing relevant material rather than waiting to be asked, which suits research work where the hard part is knowing what to look at.
It sells to institutions, does not publish pricing and starts with a demo. The audience is narrow enough that none of it applies outside financial services, and security claims of this kind are difficult to evaluate from outside.
