A genuinely clever build showed up on the Mac App Store, and it solves a problem most of us didn’t realize we’d been quietly working around. Poly-Glot AI: Prompt Studio went live this week, and it’s built for anyone who’s ever typed a prompt in English simply because that’s what prompt tools expect, even when English isn’t your first language. The creator behind it calls it the first multi-language AI prompt studio, and after reading through the Reddit thread where it launched, I get why that claim isn’t just marketing fluff.
Here’s what’s new: the app ships with over 1,000 expert prompt templates spread across 40+ categories, including dedicated tools for legal, medical, and financial use cases. There are also templates for marketing copy, academic writing, resume building, and coding help, so it’s not just a novelty for casual chats, it’s built for people who actually need reliable output for work. It’s a native macOS app, built for both Apple Silicon and Intel, running on macOS 13 and up. You can type, paste, import files, scan a photo, or just dictate your prompt out loud, so however your brain works best, the input method follows. That flexibility matters more than it sounds, because a lot of prompt managers assume you’re sitting at a keyboard with a fully formed thought, when in reality half the time you’re snapping a photo of a handwritten note or talking through an idea out loud on a walk. Standard stuff for a prompt manager, honestly, until you get to the twist.
The twist is where this gets interesting. Poly-Glot isn’t tied to one AI model. It sends your prompt straight to ChatGPT, Claude, Gemini, Perplexity, Grok, Copilot, or Mistral, whichever one you want, from inside the same app. And the whole interface, menus, buttons, templates, all of it, runs in 35+ languages, with AI responses coming back in your native language from the first word. The app is live in 33 App Store storefronts with fully localized listings, so a student in Seoul writing a college essay, a freelancer in São Paulo pitching a client, and a founder in Berlin drafting an investor email are all using the identical tool, just speaking to it in their own language. That’s the part that stands out to me: most AI tools localize the marketing page and call it done, while the actual product still defaults to English the second you open it. Everything also processes on-device, so nothing gets uploaded anywhere, which is a real point of difference from most browser-based prompt managers that route your text through a third-party server first. For anyone working with client contracts, medical notes, or financial documents, that on-device detail isn’t a nice-to-have, it’s the reason you’d trust the app with sensitive text in the first place.
If you want to try this yourself, here’s the mini-workflow the original poster laid out in the thread:
- 🗂️ Grab it from the Mac App Store and open the template library first. Don’t start with a blank prompt, browse the 40+ categories to see what’s already built for your exact use case. If you’re drafting something legal or financial, start there specifically, since those templates are structured to catch the details a generic prompt would miss.
- 🌐 Set your output language once in settings. Every response after that comes back in that language by default, no re-prompting or translating needed. This is the step people skip and then wonder why they’re still pasting responses into a separate translator.
- 🤖 Pick your AI. Poly-Glot routes the same prompt to whichever model you’ve selected, so you can compare how Claude and ChatGPT handle the identical Korean or Portuguese prompt side by side.
That routing matters more than it sounds. Different models handle the same instructions differently, so bouncing one prompt across Claude, ChatGPT, and Gemini is a quick way to catch a hallucination or a weak answer before you act on it, instead of trusting whichever model you happened to have open. It’s the same logic as getting a second opinion before you sign off on something important, except it takes ten seconds instead of a second appointment.
Pro tip: the 25 Featured templates are free to run as much as you want for the first three days, no card required for those. That’s long enough to stress-test the app against your real workflow before deciding if the $9.99 monthly or $79.99 yearly plan is worth it, the yearly option runs about a third cheaper. One commenter asked exactly this in the thread, and this Redditor answered directly with the numbers, so the pricing isn’t buried in fine print the way it is on a lot of App Store listings. Use those three days deliberately: run your actual work through it, a real client email, a real assignment, not a test prompt, so you’re judging the app on the thing you’d actually use it for.
If you’re bilingual, or you work with clients, documentation, or teammates in a second language, this is worth fifteen minutes of your evening to poke at. The gap it’s closing is a real one: most prompt tools quietly assume English is your default thinking language, and for a huge chunk of the world, it just isn’t. Compared to a plain prompt library or a browser extension bolted onto one chatbot, having 40+ categories, seven AI destinations, and 35 languages in a single native app is a different category of tool entirely.
📱 iOS is coming next according to the post, so if you’re on iPhone, keep that thread bookmarked for updates. Go check out the full discussion on r/PromptEngineering, the pricing Q&A in the comments is worth reading before you commit to a download. 🚀
