PROMT

PROMT is a broad family of neural translation products for consumers, translators, developers, and organizations. It suits teams that need formatted-document handling, terminology control, or offline deployment more than people looking for one simple translator. The main trade-off is a large catalog of separately priced products and language packs.

Overview

PROMT covers mobile apps, a free web translator, desktop software, APIs, and an on-premise server. Master NMT targets text and office documents, while Neural Translation Server brings neural translation and customization inside a business environment. Separate analysis technologies expose APIs for entity recognition, sentiment analysis, and language detection.

That range can accommodate both an individual translating files and a company integrating translation into internal systems. It also means the right purchase depends on deployment, language-pair, and integration requirements rather than on a single universal edition.

Key features

Formatted document translation

Master NMT translates DOCX, XLSX, PPTX, text PDFs, ODF, XML, and HTML while retaining formatting. This is a practical advantage for office and publishing workflows where rebuilding a translated file would add work.

Terminology control

Users can revise word and phrase equivalents, define preferred forms for proper names, add sentences to translation memory, and use glossaries. Those controls make PROMT more suitable for repeated business language than a translator that only returns a one-off result.

Offline and business deployment

PROMT says almost all solutions operate offline, and positions its desktop and server products for confidential work without an internet connection. Neural Translation Server adds scalable, on-premise deployment with neural engines and customization, a fit for organizations that cannot route documents through a public service.

Integrations and access

Software integrates with Microsoft applications, SharePoint, and CAT systems such as SDL Trados, Memsource, SmartCAT, and Across. PROMT Agent provides pop-up translation in other applications and browsers, while a Trados Studio plug-in is sold separately. APIs support application integration, including the Analyzer SDK capabilities.

Mobile and web options

PROMT.One apps for iOS and Android are free downloads with translation, dictionary, and phrasebook functions. A free online translator offers a browser-based route when offline desktop controls are unnecessary.

Pricing

PROMT uses a freemium model: a free plan and paid options from $36. The free online translator and mobile apps suit occasional translation, but recurring document work or private deployment points toward paid software.

PROMT Lite One Language Pair: $39 a month for one language pair. A focused choice when multilingual coverage is not needed.

PROMT Lite Multilingual: $59 a month for an offline multilingual text and document translator.

PROMT Master One Language Pair: $199 a month for one language pair, aimed at users who need Master-level controls without broader language coverage.

PROMT Master Multilingual: $300 a month for an advanced offline multilingual translator with personal settings.

PROMT START: $45 a month for cloud translation of multiple information types.

PROMT for MS Office: $45 a month for translation in Word, Excel, and PowerPoint.

PROMT Offline for Mac OS: $36 a month for an offline Mac translator.

One-time additions include the Trados Studio plug-in at $110, paid once and language packs at $199, paid once: Eastern European, Asian, Nordic, or French European coverage. PROMT also offers demo versions of business translators and a free trial; renewal terms and usage quotas vary by product.

Platforms

PROMT spans Android, iOS, Windows, Linux, API access, and self-hosted deployment. Master NMT requires 64-bit Windows 8.1, Windows 10, or Windows 11, at least 8 GB of RAM, and 10 GB of free disk space. A separate Offline for Mac OS plan serves Mac users. The platform breadth is strong, but each product has its own operating-system and deployment fit.

Who it's for

Choose PROMT for confidential offline translation, recurring documents with controlled terminology, CAT-tool workflows, or an internal translation service. It is also reasonable for occasional mobile or web translation at no cost. Users who want a single, clearly bounded subscription or a lightweight text-only tool may find the product family unnecessarily complex.

Pros and cons

Pros: broad coverage from free mobile and web tools to APIs and self-hosted server deployment; formatted support for major office and markup files; translation memory, glossaries, and editable terminology; offline operation suited to confidential material; Microsoft, SharePoint, and CAT integrations.

Cons: Master and server-oriented options are expensive for individual users; language-pair and multilingual editions split capabilities across many plans; the Trados integration costs extra; choosing between cloud, desktop, mobile, and on-premise products requires careful matching.

Alternatives

Papago is a better fit for mobile and web users who want freemium translation with stated monthly allowances for images, documents, and voice. iTranslate suits users seeking a free text-translation tier and a broader consumer app ecosystem. Lara Translate offers a free 60,000-character monthly allowance for one user and documents up to 10 MB. Reverso is worth considering for a consumer-focused service with a Premium Annual plan at €6.49 a year. Pairaphrase targets paid business deployments, with its Bronze plan at $3,420 a year for 1–2 users and 600,000 words. Baidu Translate is an alternative for teams needing Chinese-character allowances and self-hosted support. LibreTranslate is preferable when an open deployment model and a $29 a month Pro plan with unlimited translations are the priority. Lingvanex Translator provides a broad consumer package at $99.99 a year.

Verdict

PROMT is the right choice for users who value offline confidentiality, formatted documents, terminology management, and integration flexibility. Its principal reason to look elsewhere is the fragmented, high-cost plan structure when a straightforward consumer translator or one predictable subscription would do.
