Quick DCF wraps a compact DCF engine into a browser toolbar: type a ticker, tweak growth/WACC/terminal via sliders, and get an intrinsic-value vs current-price readout plus a 10-year FCF projection. It’s privacy-friendly (calculations local, no account) and small in size, but the idea isn’t novel — the win here is convenience and speed rather than a new valuation method. Watch the Yahoo Finance data dependency and the simplifications in the DCF assumptions if you plan to use it for real investing.
