Questions & Answers

As answered by people managing CodeSignal and Niblu.

What makes your product unique?

Niblu's answer:

Niblu is menu-native. It reads real restaurant menus (photos/PDFs), then turns them into a clear decision: Safe, Unsafe, or Uncertain based on your personal allergy/intolerance profile, with the “why” behind each call.

Why should a person choose your product over its competitors?

Niblu's answer:

Most tools are barcode-first or database-first. Niblu is built for the moment you actually need help: when you’re staring at a menu at the table. It’s fast, personal, and improves over time as you save preferences and react to dishes.

How would you describe the primary audience of your product?

Niblu's answer:

People who eat out and need to avoid specific ingredients due to allergies, intolerances, or restrictive diets (dairy-free, gluten-free, egg-free, nut-free, vegan, halal), especially travelers and busy diners.

Which are the primary technologies used for building your product?

Niblu's answer:

Next.js, TypeScript, React, PostgreSQL, Tailwind CSS, Three.js, plus AI vision + language models for menu understanding.

What's the story behind your product?

Niblu's answer:

Niblu started from the simple problem: eating out with restrictions is stressful, slow, and easy to mess up. The goal is to make restaurant dining safe and actually enjoyable again, with a tool that reads menus the way humans wish menus were written.

Who are some of the biggest customers of your product?

Niblu's answer:

  • Individual diners managing allergies and intolerances (early adopters)
  • Frequent travelers with restrictive diets
  • Families and caregivers ordering for kids with inolerances
  • Restaurant teams piloting allergen-friendly menu experiences
