We are a two-person team building K-Bap, a Korean food safety guide for people who can't read a Korean menu but need to know what's safe for them to eat.

Scan any Korean menu. See what's safe for you before you order.

Korean menus rarely list ingredients, and staff often can't explain them in English. K-Bap closes that gap for travelers and residents with allergies, dietary rules (vegan, halal, kosher, gluten-free …) and spice limits.

What it does

• Scan a menu — point the camera at a Korean menu; dishes are recognized and matched to our curated food database.
• Personal risk verdict — every dish is rated Safe / Caution / Danger / Unable to assess against the ingredients you avoid, with the reason shown.
• Ingredients, explained — what's inside each dish, how often an ingredient appears across restaurants, and translated names.
• Ask the owner — a one-tap Korean card you show to staff: "Does this contain X? I have a food allergy."
• Reviews from travelers like you — ratings and notes, filterable by your own nationality.
• Order history & reminders — keep what you ordered and get a nudge to review it later.

10 UI languages: English, 한국어, 中文(简体·繁體), 日本語, Español, Русский, Tiếng Việt, Bahasa Indonesia, ไทย.

Specs, the admin console and internal tooling live in private repositories.

• App Store Connect · Google Play Console · Firebase console · Proxyman (network QA)

• Jira for tasks, GitHub PRs with AI-assisted code review, and a spec repository as the single source of truth for product decisions.
• Safety first: a dish is never shown as "safe" unless we can verify it. When we can't, we say so and point you to the owner.

Safety information in K-Bap is guidance, not medical advice. Always confirm with the restaurant.
