Why does localization still break brand voice?

We've talked to founders, developers, and localization teams over the last few months, and one thing kept coming up: translation quality keeps getting better, but products still feel different across languages.

We're curious how others are handling this today.

Have you ever reviewed a translation that was technically correct but just didn't sound like your product anymore?

How many languages does your product support?

A lot of startups start with English only, then suddenly need to support multiple markets.

How many languages does your product currently support, and what has been the most painful part of the localization process so far?

We're collecting feedback while building LocIn AI and would love to hear real experiences.

What's your current localization workflow?

We're seeing teams use everything from spreadsheets and ChatGPT to DeepL, Crowdin, Lokalise, and fully manual workflows.

What does your localization process actually look like today?

Always interested in seeing how different teams approach the problem.

Hi Product Hunt! 👋

I'm Hamit, a technical high-school student from Türkiye.

The idea for LocIn AI came from a frustration we kept running into while building our own products. Translating an app isn't actually the hard part anymore. AI can do that in seconds.

The real problem is keeping the same voice, tone, and personality across every language.

We'd spend hours fixing translations that were technically correct but felt completely different from the original product. Marketing copy sounded robotic. Product messages lost context. And every update meant repeating the same process again.

At first, we thought this was just our problem.

Then we started talking to founders. We spoke with YC-backed startup teams, developers, and even people working in localization itself. Surprisingly, many of them told us the same thing: translation quality keeps improving, but preserving brand voice across languages is still a messy, largely unsolved problem.

That was the moment we realized we weren't building a nice-to-have feature. We had stumbled onto a gap that a lot of teams felt, but very few tools were focused on solving.

So we built LocIn AI.

LocIn AI helps teams localize apps without sacrificing their brand voice. Instead of treating translation as a one-time task, we wanted localization to become part of the development workflow itself.

A few things we're particularly proud of:

• 🎯 Tone-aware localization Your translations shouldn't sound like they came from a different company. LocIn AI preserves style, personality, and context across languages.

• ⚡ Developer-first automation CLI tools and API access make localization part of your deployment workflow instead of another spreadsheet to manage.

• 🌍 Fast global shipping Translate and update content across languages quickly, without turning every release into a localization project.

We've spent the last months talking with founders, developers, and early users, refining the product based on real feedback.

How are you currently handling localization? Have you ever run into the problem of translations being technically correct but feeling completely off-brand?

We'll be here all day answering every comment. Thanks for checking out LocIn AI ❤️

CI validation sounds useful, but I’m curious how far it goes. If a translation changes a placeholder like {{count}} or {{planName}}, does LocIn fail the check, or is validate mostly checking missing keys and basic file structure?

@novamaker01 It goes quite a bit further than basic validation. It'll catch things like missing keys, broken file structure and yes placeholder mismatches which will fail the check like you suggested. It also checks for untranslated content, makes sure HTML tags like or are preserved, and warns about suspicious cases like where a translation is dramatically longer or shorter than the source. We also support things like the --min-coverage flag if you want to enforce a minimum translation coverage in CI. If you're curious, the docs are linked on our landing page. And if you end up trying it out, feel free to reach out with feedback or feature requests. We'd genuinely love to hear what would make it fit better into your workflow

"Tone-aware" is the part most localization tools quietly skip. I'm Italian shipping apps in English, so I feel it both ways... the words come out right but the register is off, too formal or oddly casual for the screen it sits on. And a two-word button has no sentence around it to infer tone from, which is where machine translation usually guesses wrong. What's it keying off for tone when the context is that thin?

@luca_capone That's exactly the kind of problem that got us interested in this space in the first place.

When the context is thin, we lean heavily on the tone profile, glossary, and the rest of the project content to build a better understanding of how the product communicates. A two-word button on its own is tough for any system, but it becomes a lot easier when it's translated as part of a larger product instead of as an isolated string.

We're definitely not claiming to solve context perfectly every time, but we've found that giving the model a stronger understanding of the product itself gets much better results than treating every string independently.

Who reviews the output? Shipping AI translations straight to production without a human-in-the-loop step sounds risky for anything customer-facing. Is there a review workflow or glossary/term base supportt?

@ahmeterdempmk We definitely agree that blindly shipping AI-generated translations to production can be risky. That's why we have multiple review and validation layers that check translations, flag potential issues, and in some cases recommend manual review when confidence is low. We also support things like glossaries and terminology rules so teams can enforce consistency across languages. Our goal isn't to remove humans from the loop entirely, it's to dramatically reduce the amount of manual work while still keeping quality high.

The developer workflow is the strongest part for me. Localization usually becomes a messy spreadsheet process after the first few languages, so having CLI/API support from the start makes this feel much easier to maintain.

@farrukh_butt1 absolutely right. at some point every localization workflow seems to turn into "wait, where is the latest version of this file?" 😅 we're basically trying to make sure people never end up there in the first place

Tone-aware localization addresses the part that generic translation APIs get wrong. Most tools produce technically correct strings that sound robotic in the target language because they ignore register and brand voice. How does the tone model handle language pairs where formality rules are structurally different, like Japanese honorific levels or the tu/vous distinction in French?

Congratulations on the launch! 🎉 Localization is one of those problems that seems solved until you actually try to maintain a consistent brand voice across multiple languages.

@marianna_tymchuk Thank you! That's exactly what we kept running into. Getting a translation is easy now, but getting it to sound like the same product is a completely different challenge. Really appreciate the support 🚀
