## ModernMT

ModernMT is the machine translation product built by Translated, the language services company behind MyMemory. Its central idea is adaptivity: rather than a single generic model, ModernMT lets each user's project learn from their own corrections, translation memories and glossaries, so the engine's output increasingly matches house style and terminology.

The platform is aimed at professional localization teams rather than casual translation. It combines a web dashboard for managing memories, glossaries and engines with a REST API and official SDKs for Node.js, Python, Go, Java, .NET and PHP, plus plugins for CAT tools including Trados Studio and memoQ. That makes it practical to embed inside an existing translation pipeline instead of replacing it.

Important operational note: Translated is migrating ModernMT to a newer platform called Lara, powered by a domain-specific large language model. According to the company, ModernMT will sunset by the end of 2026; existing API keys and plugins remain functional until December 31, 2026, and new sign-ups on modernmt.com are closed with new users directed to Lara. Anyone evaluating ModernMT today should plan for that migration path.

**Pricing & Plans:** ModernMT has historically offered a free trial alongside paid subscription and pay-as-you-go API plans, with custom enterprise agreements. Current pricing is quoted per project and is being reworked into dedicated Lara plans during the migration, so exact figures should be confirmed with the vendor.

- **Adaptive machine translation:** The engine continuously learns from translator corrections, so quality on your own content improves with use.
- **Translation memory and glossary:** Upload and manage translation memories and glossaries so terminology and past phrasing are respected in output.
- **API and CAT tool plugins:** Integrate the engine into Trados Studio, memoQ or your own stack via a documented REST API and SDKs for Node.js, Python, Go, Java, .NET and PHP.
- **Domain-aware engines:** Context-aware engines recognize the domain of a text and apply the most relevant translation memories automatically.
- **Batch and document workflows:** Process documents and batches through the platform as part of a localization pipeline, with support for 200+ language pairs.

**Strengths:** Output improves over time by learning from your own corrections; Strong professional-tooling story with CAT plugins and SDKs; Supports 200+ language pairs; Backed by Translated, an established language services provider

**Limitations:** Service is scheduled to sunset by the end of 2026; New sign-ups on modernmt.com are closed; new users are redirected to Lara; Document, image and audio translation are not available in ModernMT itself; Advanced adaptation (context, instructions, style guides) only exists on the newer Lara platform

## slAItor

slAItor is a translation assistant built by a researcher with a PhD in machine translation. Rather than treating translation as a black box, it exposes the reasoning: every translation can be expanded into a step-by-step explanation, and you can request paraphrased alternatives or apply a specific style so the result matches the tone you need.

Its checker mode flips the workflow around. Instead of translating from scratch, you paste a translation you have already written and slAItor identifies, explains and corrects errors — a useful pattern for students, reviewers and anyone proofreading bilingual documents. The service supports 28 language pairs spanning Chinese, English, French, German, Italian, Japanese, Portuguese and Spanish.

Technically, slAItor preprocesses and tokenizes your text, packages it into a prompt for GPT-family models, then post-processes and formats the response. The team monitors quality with the COMET metric and human evaluation, and notes honestly that raw translation accuracy is slightly behind the most established systems while offering features they lack at a lower price.

**Pricing & Plans:** Paid subscription: about $25 per month for 800 credits (roughly 800,000 characters monthly), or an annual plan offering 10,000 credits per year. All languages, step-by-step mode, paraphrases, styles, checker mode, commercial use and support are included. A free interactive demo is shown on the site, and subscription seats are currently marked as closed.

- **Step-by-step translation:** slAItor walks through how it arrived at a translation so you can learn from it or verify a language you are studying.
- **Checker mode:** Submit your own translation and slAItor will spot, explain and correct any errors it finds.
- **Paraphrase alternatives:** Get five different renderings of the same text and pick the phrasing that fits your context.
- **Custom translation styles:** Apply a chosen register or writing style so translations sound appropriate for the audience.
- **GPT plus MT pipeline:** Combines classical machine translation preprocessing and post-processing with GPT-family language models, then evaluates quality with COMET and human evaluators.

**Strengths:** Explains translations step by step instead of returning a single opaque result; Checker mode validates and corrects human translations; Paraphrasing and style calibration adapt output to different contexts; 28 language pairs with no per-feature paywalls inside the subscription

**Limitations:** The developer states translation quality is slightly below well-established systems for some language pairs; Subscriptions are currently closed — new seats are unavailable, so new users may need to join a waitlist; No free unlimited tier: beyond the demo you need a paid license; Coverage is limited to 28 language pairs rather than full multilingual support
