LionRapid

Finnish CAT and localization platform with translation memory, operator-run machine translation, inspectable QA, and a localization API.

Parzialmente ospitato nell'UE

LionRapid is a translation and localization platform operated by Logoteknia Oy, a Finnish limited company (osakeyhtiö, Business ID 2489173-3). It combines a CAT editor, translation memory, terminology, inspectable quality checks, project workflow, quoting, subtitle translation, and a localization API in one hosted product.

The company built it so agencies, translators, and product teams can keep source files, translation memory, and machine translation on infrastructure the operator runs in the EU, instead of sending text to a third-party MT or AI API. LionRapid states that machine translation, including LLM steps, runs on models it operates.

The concrete differentiator is that combination: TM-first reuse, named-entity protection before MT, live language checks plus a structural rebuild-and-diff of Office and OpenDocument files, and quotes derived from hashed CAT-band analysis. The app at app.lionrapid.com is open for signup with a free tier and paid plans; pricing is public.

EU-operated (Finland)Operator-run MT (claimed)CAT + TMX/TBXStructural rebuild QAAzure West EuropeFree tier + word metering

Shortlist when you want a Finnish-operated CAT and TMS stack whose machine translation stays on the operator's Azure West Europe tenancy, with inspectable QA and hashed quoting. Skip when you need ISO 27001 or a public DPA on day one, a large connector marketplace, or a multi-person vendor support org. Consider Phrase, Crowdin, or Lokalise for GA breadth, or DeepL for MT-only.

Key capabilities

Exact and fuzzy TM matches on each segment, confirm-once fill for identical rows, TMX import/export, TBX termbases, and lemma-aware highlighting in around 35 languages. Finnish adds dedicated spellcheck, grammar, and glossary autofix that inflects the mandated term. SDLXLIFF and MQXLIFF import is documented for Trados and memoQ interchange.

The vendor states machine translation, including LLM repair, runs on models it operates on its own servers, not a third-party MT or AI API. Exact TM matches are reused first. Named entities (brand names, product codes, IBANs, URLs) are masked before the model and restored afterward. This is a first-party claim, not an audited isolation report.

Around 20 deterministic language detectors run in the editor (placeholders, number drift, glossary, untranslated leakage, Finnish grammar, malformed ICU, and more), with about 11 live as you type. A second lane rebuilds Office, OpenDocument, PDF, XML, and HTML files and diffs them against the source (49 structural issue types across 33 document detectors). Workflow stages can warn or block on open findings.

Project files are snapshotted against attached TMs into six bands (repetitions, exact, three fuzzy tiers, new words). Organization rate cards apply per-band multipliers. The quote carries a hash of the analysis snapshot so the same files and TM can be re-run later. Useful for LSPs that need reproducible estimates rather than a sales number.

REST reads and writes by locale, namespace, and key; async batch sync with retry and a dead-letter queue; a JavaScript SDK for Node, browsers, and React with cache-first sync and generated TypeScript types; plus an edge proxy or snippet for a live site. ICU MessageFormat is parsed rather than treated as opaque text. The developer page states API keys can be created in the app.

Import SRT plus common video containers, re-encode a 720p preview, translate captions as ordinary segments (TM, termbase, MT, QA), and export SRT or WebVTT with timing unchanged. Same editor as documents, so a series can share memory instead of living in a separate subtitle tool.

Best fit when

  • Language-service agencies that want TM-first CAT, hashed CAT-band quotes, and QA gates in one hosted tool
  • Teams that treat third-party MT APIs as a residency problem and want the vendor's own models on EU Azure
  • Finnish or other morphologically rich language work that needs lemma-aware terminology and Finnish grammar checks
  • Developers planning continuous localization via REST, a JS SDK, or an edge proxy
  • Orgs that must keep Trados or memoQ in the loop and only need XLIFF / TMX / TBX interchange

Poor fit when

  • Procurement requires ISO 27001, SOC 2, or a downloadable DPA before a pilot
  • You need a large connector marketplace rather than XLIFF/TMX/TBX plus the vendor's own API
  • You only need a standalone MT API (DeepL is the closer European product)
  • You require a large vendor with a multi-person support org and published backup/email subprocessors
  • Policy forbids any US-group cloud, including Azure West Europe

Consider instead when

  • When: You need a translation management system with a large connector catalog

    Consider: Phrase, Crowdin, or Lokalise

    Broader marketplace maturity. Weaker on operator-run EU MT isolation as LionRapid describes it.

  • When: You only need European machine translation, not a CAT/TMS

    Consider: DeepL

    German MT API, generally available. Not a full editor, quoting, or agency workflow suite.

  • When: Clients mandate a desktop CAT and you only need the editor

    Consider: Trados or memoQ

    LionRapid documents XLIFF/TMX/TBX interchange with those tools rather than replacing them.

No known US parent. Azure is a US-group cloud and PostHog is US-headquartered with an EU region, so CLOUD Act exposure is medium, not low. Indicative only, not legal advice.

Considerations & known limitations

  • MediumUS-group cloud (Azure) and PostHog

    EU region does not remove Microsoft (or PostHog) as a US-group processor. If policy forbids US-group clouds entirely, this stack does not qualify.

  • MediumNo public audit, ISO, SOC, or DPA

    Vendor is explicit about skipping rented badges. That honesty does not replace artifacts many security reviews require.

  • MediumSmall independent operator

    Logoteknia Oy is a 2012 Finnish translation company with a single recorded employee on Finnish registers. Set support and continuity expectations accordingly.

  • MediumOperator-run MT is unaudited

    Keeping text off third-party MT APIs is the headline claim. Isolation, model training use of customer text, and entity-masking correctness are first-party statements only.

  • LowBackup, DR, and email subprocessors unpublished

    Privacy and EU-hosted pages name Azure, PostHog, and Ahrefs. Backup, disaster recovery, and transactional email are not listed publicly.

Open questions for due diligence

  • Will Logoteknia sign a B2B DPA that lists Azure, PostHog, Ahrefs, plus backup, DR, and email processors?
  • Is customer text used to train the operator's MT/LLM models, and can that be contractually excluded?
  • Is any independent security assessment or ISO 27001 roadmap available under NDA?
  • How is Azure tenancy isolated (single-tenant vs shared), and are backups confined to West Europe?

Domande Frequenti

The app at app.lionrapid.com offers login and new-user registration. Pricing is public: a free tier with a limited word allotment for real documents, then paid subscription tiers where the platform is included and machine translation is metered by words, with optional word packs. Exact euro amounts change; check the official pricing page. Do not treat marketing copy as a procurement quote.

The company says no. The EU-hosted, security, and CAT pages state that MT and LLM steps run on models LionRapid operates, after TM reuse and entity masking, and that text is not shipped to a third-party AI or MT API. There is no independent audit of that path. Confirm it in a DPA and architecture review before you put regulated content on the platform.

Yes, on the interchange the site documents: TMX memories, TBX termbases, XLIFF in and out, and import of SDLXLIFF / MQXLIFF. Formatting is stored as structured data rather than inline tags, then rebuilt on export for Word, Excel, PowerPoint, OpenDocument, HTML, XML, and related types. It is not presented as a full desktop-CAT replacement for clients who mandate Trados or memoQ.

Primary hosting is Microsoft Azure in West Europe. Named processors on the privacy and EU-hosted pages are PostHog (EU cloud, product analytics) and Ahrefs (cookieless traffic stats). Backup, DR, and email providers are not listed. Azure is a US-group cloud, so CLOUD Act exposure is not low even though the operator is a Finnish company with no known US parent.

No public DPA, ISO 27001 certificate, or SOC 2 report was found. The security page says the company does not display certification logos it has not earned. The marketing-site privacy policy covers the website and names the Finnish Data Protection Ombudsman. The app at app.lionrapid.com is said to have its own terms and in-app privacy notice, which were not fully extracted as a product DPA.

Choose a large TMS (Phrase, Crowdin, Lokalise) when you need a broad connector catalog and multi-region enterprise packaging. Choose DeepL when you only need a European MT API. Shortlist LionRapid when operator-run MT on Azure West Europe, inspectable QA, hashed quoting, and Finnish-operated control matter more than marketplace breadth, and you can accept a small independent vendor.
