YieldStack's answer
AI integrations supporting the platform’s workflows.
Subti.app's answer:
Subti is a native macOS application built in Swift. It integrates with VLC through a transparent interactive overlay and supports local language models and Ollama for translation. The web and licensing infrastructure uses Cloudflare Workers, D1, R2, Paddle, and Sparkle for updates
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.
Subti.app's answer:
Subti makes VLC subtitles interactive on macOS. You can click individual words or select whole phrases, get contextual translations without leaving the film, save useful vocabulary, review it with spaced repetition, and export it to Anki. It is local-first, requires no account, and can work with local translation models
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.
Subti.app's answer:
Subti is focused on a simple workflow: watch, click, understand, save, and review. It works directly with VLC and local video files instead of requiring a browser-based streaming service. It also supports phrase-level contextual translation, local translation backends, spaced repetition, and Anki export in one macOS app
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
Subti.app's answer:
Language learners who watch films and TV shows with subtitles, especially intermediate and advanced learners who want to learn vocabulary and expressions from real dialogue without constantly switching between the video player, translator, notes, and flashcard apps
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.
Subti.app's answer:
Subti started from a personal frustration with learning languages through films. Looking up an unfamiliar word usually meant pausing VLC, opening a translator, copying the subtitle, saving the word somewhere, and then returning to the film. Subti was built to keep that entire workflow inside the viewing experience
