Nitro 4.0
Launched this week
Nitro is now the first human translation service an AI agent can order and pay for on its own — no account, no API keys, no signup.
Your agent sends the text, pays per request, and a professional native speaker translates it — publication-ready in hours. Great for the smaller texts that still need to be right: ads, app updates, email sequences, and more.
The ordering is machine-to-machine. The translating stays human.
80+ languages. No plans, no minimums.

Alconost Localization Lab
Hi Product Hunt!
I'm Diana, product manager for Nitro. I've been in this role for eight years, so I've watched Nitro grow up.
When we started, Nitro was a simple platform for one thing: getting short texts translated by professional human translators, fast. Over the years we built it into something much more powerful — adding context so translators get it right (screenshots, tone of voice, character limits) and expanding what you can send.
Each of our past Product Hunt launches marked one of those leaps:
First launch: the core service, API, and export to Google Sheets
Second launch: file support — Google Docs translation with formatting preserved
Third launch: developer and content formats like JSON, HTML, iOS Strings, XML, and Google Sheets
Despite being a niche product, Nitro got noticed here. A #4 Product of the Day and two #5s for a product this niche still surprises us, and it's thanks to this community. Grateful and a little humbled every time — that's why we're back today to show you what's next.
What Alconost has always strived for is the same: pair genuinely good human translation with the most powerful tech we can build around it. This launch is the latest step. Nitro now supports MPP — the machine payments protocol — so an AI agent can order a human translation and pay for it on its own, with no account and no API keys. You hand your agent the task, it sends the text and pays per request, and a professional native speaker delivers the copy.
We think it'll be interesting for folks building with agents — Nitro is the first translation service to offer this — and we hope the localization crowd finds it just as interesting. We'd love your thoughts and questions!
Publication-ready in hours is a bold claim. I'd love to see actual turnaround data from real orders before I trust it for anything client-facing.

@morgan_nabors you are right, it is. The actual figures on the landing page is 2-24 hours as the average turnaround time. We used to have a real-time dashboard on the landing page, and usually about 60% of orders were completed within 2 hours.
But I should say most orders on Nitro are small volume - something for which a regular process with a project manager and invoicing is too much hassle. I've made a screenshot from some recent orders - again, most of them are small, but the one that's marked 'Google Docs' is over 2,000 characters - still not large, but anyway, finished by a real native-speaking translator in 1h 41 min.
Do you see this being used mostly for app localization, or are email campaigns and marketing copy becoming the bigger use case?
Alconost Localization Lab
@james_wilson60 a lot of Nitro customers come from Alconost (our company that specializes in localization), so they are mostly app & game developers, but there is a growing base of marketers (say, for SaaS products, hospitality industry, etc.) who translate landing pages, email sequences, texts for their banners and promo videos. Apps and games also order translations for marketing - like app store copy, subtitles for videos, sometimes answer templates for app store reviews.
Congrats on the launch! qq When an agent orders with no account, how does the translation get back to it?
Alconost Localization Lab
@alieksia Thanks! The agent gets an access token back when it places the order, then just polls and pulls the result through the API when it's ready - no account or dashboard needed, it all stays in the agent's flow.
Alconost Localization Lab
@alieksia Also, I'll share the docs in case you'd like to see the exact flow: https://docs.nitrotranslate.com/agentic-flow
@margarita_s88 Thank you! I'll check it out
Congrats on a new launch, guys! I am wondering something: how do you ensure quality if an agent is placing the order?
Alconost Localization Lab
@elena_kozak thank you! Quality comes from the translators, not the ordering method - the same professional native speakers handle the work whether a human or an agent placed the order. The agent just automates the request; the human standard behind it is unchanged.
How do I connect my agent to Nitro? how does it order a translation?
Alconost Localization Lab
@kseniya_avtukhovich It's a standard MPP flow, so any MPP-compatible agent can do it - no account or stored balance needed.
In short: your agent sends a translation request to our API, gets back a "payment required" challenge, pays per request through its MPP provider, then retries with the payment credential and receives the order. It polls until the translation's done and pulls the result.

80+ languages with no minimums is the part that stands out to me. I've been priced out of smaller translation jobs before because agencies wanted a monthly contract.

@kimberly_west thank you! Yes, that's exactly the problem Nitro has been saving - ad hoc translation requests with a wide range of language pairs covered. It wouldn't be possible to create such a service with a stable level of translation quality if it wasn't for our 'parental company', so to say, that offers localization services and has a large pool of translators with a track of Alconost projects. Nitro is like a side job for them with occasional orders between their main projects.
