What are the biggest challenges when building a truly global product?

Hey Product Hunt community! 👋

I’m currently working on a product designed for users around the world, and as exciting as it sounds, building something truly global comes with a lot of unexpected challenges.

Here are a few that I’ve encountered so far:

1.Localization — Translating text is just the beginning. Cultural context, tone, and even color choices can affect how users perceive your product.

2.AI prefers English — One specific issue I’ve noticed: even when users interact in their native language, the AI often replies in English—especially for code-related prompts. Balancing model behavior to respect user language while maintaining technical clarity is a tough challenge.

3.Time zones & scheduling — Coordinating actions (like notifications, support, or real-time interactions) across time zones is trickier than it seems.

4.Language limitations — Supporting multiple languages often means dealing with UI constraints, font rendering, and even right-to-left layouts.

5.Legal and compliance differences — Privacy laws, payment regulations, and data hosting rules vary greatly between countries.

I’m curious to hear from others building global or multilingual AI products:

• How do you handle language fallback or preference issues with AI?

• What’s been your biggest unexpected challenge?

And to non-English native speakers out there:

• What’s your biggest frustration when using "global" tools that are clearly built with English-first assumptions?

Would love to hear your thoughts and real-world experiences! 🙌
