Frequently Asked Questions

An online information platform that collects and organizes public financial, career and government data every day. Three pillars: ① Today's Market (KR+US quantitative value screener, global dashboard, guru 13F) ② Career (AI mock interviews, jobs globe) ③ Owl AI assistant. We provide information and tools — not buy/sell recommendations.

Every morning at 06:00 KST (before the US market opens) we re-score every KR and US stock on 7 metrics — PER, PBR, ROE, operating margin, EV/EBITDA, dividend yield, and interest (volume) — scaled to 100. 80+ is grade A, 65+ B, 50+ C, below is D. It is a quantitative assessment built on public filings (DART·SEC) and market data (KRX).

Open the screenerScoring explained

How many of five quantitative value strategies a stock passes: Graham margin of safety, Magic Formula (Greenblatt), Prasad low-PER × high-ROE, simplified DCF, and Damodaran sector-relative. Passing 3+ means several independent value signals agree. Approximate — for reference.

Grades, scores and the full score-sorted ranking are Premium features. Free shows 12 representative names (by market cap) with PER, PBR and price. Subscriptions fund the daily data collection and analysis.

Batch data (scores, grades, job postings) refreshes every weekday morning at 06:00 KST (before the US market opens). Live prices update roughly every 30 seconds during market hours. Every screen shows its data timestamp.

Owl's morning briefing, today's pick, a KR/US sector heatmap, gainers & losers, guru moves, your watchlist, live rankings (Toss Securities data), and US & Korea Fear-and-Greed — world markets on one screen.

Open the dashboard

Quarterly portfolios of nine legendary investors (Buffett, Dalio and more), built from SEC 13F filings. Note 13F data is published up to 45 days after each quarter ends — it is not real-time.

Open Gurufolio

Go to Career → Mock Interview and set up in 3 steps: ① practice style (one question at a time, or back-to-back like the real thing) ② interviewer persona (6 styles) and question type ③ your pace. Owl asks aloud, listens to your answers, then scores you on logic, specificity, confidence and fit with improvement tips. It's okay if it's your first time.

Start practicingInterview guide

Yes — upload the org intro, job posting or interview reviews (PDF·TXT·MD or plain text) in Custom Interview, and Owl asks questions grounded in your materials. Share it by link, or post it to the community; enough hearts promote it to an official interview.

Build a custom interview

Voice interviews (Owl speaks and listens) come with Career PRO — 5 per month. Text interviews are unlimited, and when the voice quota runs out we switch you to text automatically so practice never stops.

Career PRO

Korean public-institution postings (ALIO) and US federal jobs (USAJOBS), collected every morning and shown with a globe. Expired postings disappear automatically, and anything closing within 3 days is highlighted in coral. The "🦉 Practice this org" button pre-fills a custom interview for that organization.

Open Jobs Globe

Stocks are global products priced in USD: FREE (basics) / PREMIUM $5.99/mo / PRO $35.99/mo. Career is a separate Career PRO plan (₩9,900/mo, Korea) with voice interviews and 20 saved custom interviews. See the pricing page for the full comparison.

Owl Labs organizes public data for information purposes. It is not investment advice and not a buy/sell recommendation. Scores, grades and fair-value estimates are quantitative approximations and do not guarantee returns. Investment decisions and responsibility are your own.
