Translate your app with tone-aware AI, automated localization workflows, CLI integration, and instant API access. Launch globally while keeping your brand voice consistent across every language.
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 ❤️
As a solo dev whose first language isn't English, I feel this in reverse — my app ships in English and I second-guess the tone of every button label. Tone profiles + a CLI workflow sounds way better than my "paste strings into ChatGPT" routine. Does it support iOS String Catalogs (.xcstrings) natively?
We've translated products into multiple languages before and keeping the same tone everywhere was always harder than the translation itself
I think you've identified a very real problem. Translating text is easy today, but making it sound like the same brand in every language is much harder.
What stood out to me is your focus on preserving tone and personality, because that's often what gets lost when products expand to new markets.
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?
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.
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?
"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?
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?
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.
