Linglass's answer
Linglass turns any YouTube or Netflix video into a language lesson without leaving the player. It shows two subtitles at once — the original and a translation — and lets you click any word for an instant, in-context translation with native pronunciation. The standout: if a video has no subtitles at all, Linglass can generate them automatically with speech recognition and translate them, which typical subtitle tools can't do. Every word you save becomes a spaced-repetition flashcard with a screenshot and audio clip from the exact moment you saw it.
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.
Linglass's answer
It works on the videos people already watch — any YouTube or Netflix title — not a small licensed catalog. The free tier is genuinely usable (unlimited saved words and a daily translation allowance), not a locked trial. And it combines in one place what competitors spread across separate tools: dual subtitles, click-to-translate, native pronunciation with IPA/Pinyin/Romaji, AI grammar explanations, and FSRS spaced-repetition flashcards — plus auto-generated subtitles for videos without captions. Available as a browser extension (Chrome, Edge) and an iOS app.
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.
Linglass's answer
Self-directed learners who study through immersion — watching YouTube, Netflix, anime, dramas, and interviews in a foreign language instead of taking structured courses. They're typically intermediate learners who like the "comprehensible input" approach, often studying English, Spanish, Chinese, Japanese, or Korean, and want to turn the content they already watch into study material and remember new words long-term.
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.
Linglass's answer
Linglass started from a simple frustration: watching foreign-language video is one of the best ways to learn, but the workflow is clunky — pausing constantly, copying words into a dictionary, then into a separate flashcard app. Linglass brings all of that into the video itself: dual subtitles, one-click translation and pronunciation, and automatic flashcards. It grew from a browser extension for YouTube and Netflix into a cross-platform tool with a web app and an iOS app.
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.
