What problem does it solve?
Studying a company properly means hopping between places today: the price on one site, the annual accounts in a regulator PDF, the valuation in a spreadsheet of your own, and the news somewhere else again. Every hop costs time and, worse, breaks the thread of the analysis.
Celsmar puts that whole path on one screen: price, historical accounts with their ratios, a discounted cash flow valuation with the assumptions in plain view, a portfolio with risk metrics, and the context of news and calendar. Same company, same numbers, without starting over at every step.
How is it different from a quotes website?
A quotes website answers what a share is worth right now. Celsmar tries to answer something harder: whether that price makes sense. To do that it shows how every figure is computed, with its date and its time, and lets you move the valuation assumptions to see how much the result changes.
There is also one rule that is not up for negotiation: when a data point does not exist for a given company, it is flagged as missing rather than estimated. That looks worse than filling every gap, but it is the only way the figures that do appear can be used to decide anything.
