The Localization Manager

Weighted verdict

Runs localization for a Hamburg software company whose product, help centre and marketing site ship in fourteen languages, with two agencies and a pool of freelancers. Every release brings a few thousand new strings and a deadline. Wants one translation memory and termbase across all content, machine translation that respects the glossary, review steps per language, QA checks that stop a broken placeholder before it ships, and cost and progress per vendor in one view.

Same scores as the panel view — this lens weights them the way this judge cares.

Machine translation & AI quality

How this is scored

What the machine translation does and how well it is controlled: the languages and language pairs covered, the engine (own neural or LLM model, or a choice of third-party engines such as DeepL, Google, Microsoft or an LLM), glossaries and formality applied during translation, document translation that keeps the layout (Word, PowerPoint, PDF, InDesign), custom or adaptive models trained on the customer's own translations, automatic quality estimation or scoring, and published evaluations of translation quality.

0 — No machine translation of any kind, and no way to connect an engine.

3 — Machine translation is offered or one engine can be connected; languages, glossary use and quality controls are basic or not described.

5 — Machine translation for the major European and world languages with the list published, glossaries applied during translation, a formality or tone setting, document translation that keeps formatting for common office formats, and either an own engine or a choice of several named engines.

8 — Custom or adaptive models that learn from the customer's translation memory or corrections, automatic quality estimation per segment with a threshold that routes weak segments to human review, LLM-based translation with style guides and context, engine selection per language pair stated, and a published quality evaluation with its method.

10 — Translation quality that an organisation can measure and steer: evaluations against named benchmarks or blind human review published with their method, quality estimation calibrated and explained, custom models with their training data and isolation documented, and every machine-translated segment traceable to the engine, model version and glossary that produced it.

The Localization Manager

Tolgee offers a choice of named engines — its own AI translator alongside AWS, DeepL, Google and Azure — with providers configurable per language, a formality setting, custom AI prompts, glossaries, and self-hosted lets us bring our own keys for engines and LLMs including self-hosted models, with machine translation switchable off. We found no published list of supported languages, no layout-preserving document translation for Office or InDesign formats, no custom models learning from our translation memory, and no quality estimation or published quality evaluation. 2 11 12 15

Translation memory, terminology & review workflow

How this is scored

How translation is managed as an ongoing process: translation memory with fuzzy matches, a termbase or glossary managed centrally, style guides, review and approval stages, automated QA checks (placeholders, tags, length, terminology, punctuation), an in-context or visual editor, screenshots and context for translators, tasks and deadlines, roles per language, and ordering or inviting human translators and agencies inside the product.

0 — No management of translations at all; text goes in and comes out with nothing stored or reviewed.

3 — Translations can be edited or a glossary kept; translation memory, review stages and QA checks are basic or not described.

5 — A translation memory reused across projects, a central glossary, at least one review or approval stage, automated QA checks for placeholders and terminology, comments and screenshots for context, and roles that limit translators to their languages.

8 — Configurable multi-step workflows with automation rules, an in-context or visual editor for apps or websites, QA checks configurable per project with blocking rules, style guides applied by the AI, translation memory and termbase shared across projects with penalties and priorities, vendor or agency management with ordering inside the product, and progress and cost reporting per language.

10 — A translation process an enterprise runs on: workflows per content type with conditional routing on quality scores, linguistic quality assessment with a named framework (MQM or similar), termbase with approval workflow and forbidden terms, full revision history per segment, and productivity and quality metrics per translator and vendor.

Report an error

The Localization Manager

A translation memory with similarity-based suggestions can be shared across projects and imported or exported, a central glossary carries term types such as non-translatable, states run Untranslated, Translated and Reviewed with keys assignable as tasks, and QA checks flag placeholders, punctuation, spacing and formatting with warning, error or off severity — the gate I need before a release ships. In-context editing works even in production with one-click screenshots and comments, and professional translation can be ordered inside the product from Alconost or Dialect, though cloud only. We found no public information on configurable multi-step workflows, style guides applied by the AI, or progress and cost reporting per language and vendor. 1 3 4 7 8 12

Integrations, file formats & developer tools

How this is scored

How content gets in and out: the file formats supported (XLIFF, PO, JSON, YAML, Android XML, iOS strings and xcstrings, Office documents, InDesign), a REST API and CLI, SDKs and over-the-air updates for apps, Git repository sync (GitHub, GitLab, Bitbucket) and CI pipelines, connectors for CMS, shop and design tools (WordPress, Contentful, Shopify, Figma), browser and office add-ins, webhooks, and a JavaScript snippet or proxy for website translation.

0 — No documented way to get content in or out except typing or pasting by hand.

3 — File upload and download or a basic API; formats, repository sync and connectors are basic or not described.

5 — A documented REST API, a list of supported file formats covering the common software and document formats, sync with at least one Git host or CI, and connectors or plugins for several named CMS, shop or design tools.

8 — A CLI and SDKs for named platforms, over-the-air updates for mobile or web apps, Git sync with branching, webhooks, connectors for the main CMS, shop, design and support tools, office or browser add-ins, a public status page, and API limits documented.

10 — Integration that scales across an organisation: an API covering every function of the product with versioning and SDKs, an app or connector framework third parties build on, continuous localization in CI with pull requests opened automatically, and every connector documented with its limits and the fields it syncs.

Report an error

The Localization Manager

The format list covers the software side well — JSON, XLIFF, PO, YAML, RESX, Android XML, Apple strings and stringsdict, Flutter arb, CSV and XLSX — with a REST API stated to do anything the UI can, a CLI, webhooks, over-the-air content delivery, an MCP server, and SDKs for React, Angular, Vue, Svelte and Next.js plus browser plugins, Figma and Slack. We found no public information on Git repository sync, CI pipelines, or connectors for CMS, shop and support tools beyond Figma and Slack, and no documented API limits or public status page. 4 5 7 13 14

Confidentiality of translated content

How this is scored

What happens to the text a customer translates: whether source and target texts are stored and for how long, deletion after translation, whether customer content is used to train the vendor's or a third party's models, which machine translation and LLM providers a TMS sends text to and whether that can be restricted or switched off, encryption in transit and at rest, single sign-on, roles and audit logs, and certifications (ISO 27001, SOC 2) with their scope. Where the text is processed is scored under sovereignty.

0 — Customer texts are stored indefinitely and used for the vendor's own purposes, or no statement on data handling exists at all.

3 — The product is described as secure or GDPR-compliant and a privacy policy exists; retention of translated texts, model training and third-party engines are basic or not described.

5 — A documented statement that customer texts are not used to train models, retention or deletion of translated texts stated, the third-party engines or LLM providers named, encryption in transit and at rest, single sign-on on a business tier, and a data processing agreement offered.

8 — Texts deleted immediately after translation or after a retention period the customer sets, third-party AI processing switchable per project or account, zero-retention terms with the named LLM providers, audit logs, granular roles, ISO 27001 or SOC 2 certification stated with its scope, and a private or dedicated deployment option.

10 — Confidentiality that can be verified: an on-premise or customer-controlled deployment, customer-managed encryption keys, every subprocessor that sees content listed with its role, independent audit reports available, and every data flow of a translation request documented end to end.

Report an error

The Localization Manager

The vendor states that customer data is not used to train AI models, names the machine translation and LLM providers text can go to with an opt-out, and says LLM providers are chosen whose API terms do not train on submitted data, with deletion from production and backups within seven days, TLS and AES-256, ISO 27001, role-based access, audit logging and a self-hosted option where the vendor sees no projects, users or logs. The data processing agreement is available only on request for enterprise customers, and the terms disclose that the vendor sometimes looks into user projects via session replay for UX improvement and debugging, which matters for confidential marketing copy. 9 10 11 15

Report an error

Data export, portability & self-hosting

How this is scored

Whether translation assets stay the customer's and can leave with them: export of translation memory and termbase in open formats (TMX, TBX, XLIFF, CSV), export of all projects and files, import from another TMS, an API that can read every asset, the return or deletion of data on termination, open-source code and a self-hosted or on-premise edition.

0 — Translations cannot be exported; they exist only in the vendor's interface or engine.

3 — Translated files can be downloaded; export of translation memory and glossary, import and termination terms are basic or not described.

5 — Translation memory exportable as TMX and glossary as TBX or CSV, all project files downloadable, import of translation memory and glossaries from another tool, and an API that reads translations and keys.

8 — Complete export of every asset (memory, termbase, files, comments, history) in open formats, a documented migration path from named competitors, the data returned or deleted on termination under stated terms, and a self-hosted or on-premise edition with its own documentation.

10 — The customer owns the assets end to end: open-source code under a named licence that runs fully self-hosted with feature parity stated, a complete export another tool can import without loss, and the deletion of every copy on termination documented.

Report an error

The Localization Manager

The core is Apache License 2.0 with the enterprise directories removable to build fully open-source binaries, and the free self-hosted edition has its own documentation, unlimited translation keys and an upgrade path that keeps data intact; the translation memory can be imported, exported and shared across projects, and the REST API is stated to do everything the UI can. Termination terms state all your data may be permanently erased, with a carve-out for resultant data. We found no public information on termbase, comment or history export, on named TMX or TBX interchange for memory and terms, or on a documented migration path from the competitors the vendor compares itself to. 6 9 12 13 15

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where texts are translated, stored and processed, and who the subprocessors are (hosting, machine translation engines, LLM providers, CDN for over-the-air delivery, support and payment tools). Independently sourced by the sovereignty pipeline; translated texts often hold personal data and trade secrets, so the whole chain counts, including the engines a TMS calls. A self-hosted edition the customer runs on its own European servers counts as the customer's chain, whatever the vendor's seat.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.

3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.

5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (machine translation or LLM providers, CDN, support, payment) run through non-EU providers without a stated safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessors listed with their locations including the engines and LLM providers, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated — or a self-hosted edition documented that keeps every text on the customer's own servers.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting, engine and every subprocessor, or a self-hosted open-source edition with no call home, data export and deletion documented, and certifications published with their scope rather than implied.

Report an error

The Localization Manager

Tolgee s.r.o. is a Czech entity registered in Brno under Czech governing law, servers are stated to sit in Germany, Czech Republic and the United States on named Microsoft Azure and AWS infrastructure, subprocessors are named including the machine translation engines, analytics and error reporting run in EU regions, and ISO 27001 is stated. A self-hosted edition is documented where the vendor says it does not see projects, users or logs, keeping every text on our own servers — the route our residency rules would push us to. The data processing agreement is available only on request for enterprise customers rather than published, and the captured pages give no allocation of which data runs in the United States or the locations of the translation engines themselves. 9 10 11 15

Pricing transparency

How this is scored

Whether a buyer can compute the real annual cost from public pages alone: price per tier by characters, words, keys, hosted words or seats, what happens when the volume exceeds the tier, the number of users, projects and languages included, which features (machine translation volume, AI credits, SSO, integrations, API access) cost extra, the free tier and its limits, the self-hosted edition and its support, minimum term and setup.

0 — No public prices at all; every customer is a sales call.

3 — A starting price or a free tier exists, but how cost scales with volume, seats or features is unclear.

5 — Tiers are public with their price per volume band and main inclusions, but at least one commonly needed piece (overage, extra seats, machine translation or AI volume, SSO, connectors) is unpriced or "on request".

8 — Every tier priced publicly with its scaling rule (characters, words, keys, seats), overage handling stated, add-ons and AI credits priced, the self-hosted edition's cost or licence stated, minimum term and VAT treatment stated.

10 — Complete price computability: annual cost derivable for a given volume, seat count and feature set, with every add-on, setup, support and overage fee and the cancellation and data-return terms published.

Report an error

The Localization Manager

Cloud pricing is public: a free tier with 30,000 hosted words, 10,000 MT credits and 3 seats, then Translate at €58/mo, Optimise at €133/mo and Manage at €373/mo billed annually with two months free on annual payment, word bands from 50k to 10M in EUR or USD, unlimited seats and projects, and the conditions state fees are exclusive of taxes, non-cancelable and non-refundable with auto-renewal. Enterprise — where single sign-on sits — carries no public price, and self-hosted licensing is described as based on keys and seats and tailored to your setup, with prices not published. We found no public information on overage handling, additional MT credit pricing, or adding seats. 1 6 8 9 15
