"longDescription": "Feasly brings real estate financial modelling into ChatGPT.\n\nExplore a development opportunity, work through an investment case or understand the assumptions behind a valuation. Ask a question, test a change and see what it means for cash flow, funding and returns.\n\nBuilt for developers, investors, valuers and asset owners working on development feasibility, appraisal, pro formas, acquisition underwriting and discounted cash flow (DCF) valuation.\n\nWhat you can do\n\u2022 Open a saved Feasly model, create a new case or import a supported model file.\n\u2022 Review assumptions, cash flows, value and returns.\n\u2022 Test changes to costs, timing, income and financing.\n\u2022 Compare a separate scenario with your original case.\n\u2022 Save the work and continue in your Feasly workspace.\n\nThe Feasly Calculation Engine calculates the financial results. ChatGPT helps you explore the questions and understand the answer.\n\nPart of the wider Feasly platform\nFeasly connects market research, site analysis and financial modelling across development, investment, valuation, asset performance and portfolio decisions. This plugin gives you another way to work with your models and scenarios.\n\nGetting started\nTry a quick development appraisal without signing in, or connect an enabled Feasly account for saved projects and scenarios. Quick appraisals are before tax and borrowing. Results depend on your inputs and the supported calculation method.",
