YieldStack's answer
AI integrations supporting the platform’s workflows.
Foretaste.page's answer:
Built with WXT and Astro. OCR runs on Tesseract compiled to WebAssembly, executing in a browser worker.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Foretaste.page's answer:
It reads a file from its link without downloading it first — for a ZIP archive, that means reading only the index at the end of the file (a few kilobytes) instead of the whole thing. Everything happens locally in the browser; there's no server the file passes through.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
Foretaste.page's answer:
Most tools in this space either only handle one format (ZIP-only viewers) or hand the file's address to a hosted viewer like Google Docs Viewer, which sends where you are and what you're looking at to a third party. Foretaste parses everything locally and covers 105 formats in one extension.

Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
Foretaste.page's answer:
Anyone who gets sent a file they're not sure about before they want it on disk — students checking course material links, developers inspecting release archives and logs, researchers previewing datasets, and anyone on a work or shared computer who'd rather not download something first to find out what it is.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
Foretaste.page's answer:
It started from a personal annoyance: going through around 100 files a day - checking release archives, course materials, reports people sent - and downloading every single one just to find out what was actually inside it. Most of them weren't what they claimed to be, or weren't needed at all, and they still ended up cluttering a downloads folder. Foretaste is the tool that should have existed already: right-click, look inside, then decide. Built first to solve that for one person doing it 100 times a day, not as a product idea that came before the problem.
