Localization areas

Primary and supporting use cases
Job coverage

Selected jobs

22 distinct jobs across 6 localization areas

StrongApply style guides and brand voice ↗

A supplied style guide is applied to translation jobs and can affect register choices alongside memory and other context.

Condition: Requires a customer-supplied style guide.Localize.io tour source ↗
StrongApprove translations with in-country reviewers ↗

Customers can add their own people as account or project reviewers. They sign in to assigned work and approve or correct each string, with verdicts and notes returned in review-job results.

Condition: Reviewer configuration and per-job routing require setup; review availability and rates depend on configured reviewers.Localize.io tour source ↗
StrongBuild pipelines with APIs, CLIs and SDKs ↗

Provides REST API and MCP integration; orders and results can be exchanged as API-schema data, files or plain text, and Enterprise describes custom connectors.

Condition: Requires API credentials. Custom connectors require Enterprise setup.Localize.io OpenAPI specification source ↗
StrongChoose and combine MT and AI engines ↗

Customers can choose listed model providers and configure model routes per language, content type, project and pass; tour examples show different routes for UI, marketing and review work.

Condition: Only models available through the service or customer configuration can be selected; enterprise also advertises own providers/models.Localize.io tour source ↗
PartialControl where AI translation runs ↗

Supports customer provider keys and Enterprise instances on customer infrastructure with customer model accounts.

Condition: Own infrastructure requires an Enterprise arrangement; model hosting and data terms depend on the selected provider.Localize.io integration skill source ↗
PartialCustomize MT for your domain ↗

Uploaded domain glossaries and style rules condition model translation output; per-order instructions provide a brief for the submitted content.

Condition: Glossary, style and instruction conditioning; model training and fine-tuning are outside this fit.Localize.io tour source ↗
PartialDeliver translations into builds and files ↗

Returns translated files or structured results in the submitted shape, checking identifiers, placeholders and tags for downstream integration.

Condition: The caller collects the result and handles repository commits or publication.Localize.io tour source ↗
StrongEnforce approved terminology ↗

Glossary terms are selected for relevant strings; automated terminology checking identifies failures and sends them through retry before delivery.

Condition: Requires glossary/terminology material and configuration; checks do not establish that every preferred term is automatically enforced without exceptions.Localize.io tour source ↗
PartialExchange assets in open formats ↗

Imports TMX/XLIFF translation memories and TBX terminology as reusable linguistic assets, and lets customers download their original uploaded files unchanged.

Condition: Imports and retrieves customer-owned open-format assets; generating new translation-memory exports is outside this fit.Localize.io tour source ↗
PartialForecast and control localization spend ↗

A customer can set a monthly USD budget cap; the budget endpoint reports delivered spend, estimates in-progress work and refuses an order that would exceed the cap.

Condition: This is a monthly cap and current estimate, not volume forecasting or vendor-cost management.Localize.io llms.txt source ↗
StrongGive translators context ↗

Accepts screenshots and per-string context along with glossary, translation memory and style rules; the tour shows that these inputs are matched to strings to give translators context.

Condition: Screenshot annotations are generated once and described to the translator; the image itself is not presented as a live in-product review surface.Localize.io tour source ↗
PartialKeep an auditable translation record ↗

Job traces retain routing, model calls, supplied context, checks, warnings and costs; account logs cover job and asset events.

Condition: Covers model/job traces and asset events; a complete human approval audit is outside this fit.Localize.io llms.txt source ↗
PartialMaintain translation memories ↗

Stores customer- and project-level memory assets, keeps asset versions, and permits restoring a prior file.

Condition: Customers edit and re-upload their memory files; this fit covers storage, versions and restoration.Localize.io llms.txt source ↗
PartialManage terminology ↗

Stores multilingual approved-term files at account and project levels, allows replacement/removal and asset-version restoration, and applies project terms over conflicting account terms.

Condition: File-based terminology maintained at account/project level; customers author the source termbase externally.Localize.io tour source ↗
PartialMatch content to quality tiers ↗

Routes work to configured models by language, content type, project and pass, and can name a human reviewer for a review pass.

Condition: User-configured model routing with an optional named human review pass; a formal quality-tier policy framework is outside this fit.Localize.io tour source ↗
PartialOrder human translation on demand ↗

Customers can buy a human review of translated content through the API using a service-provided linguist listed with language pairs, content types and per-character pricing.

Condition: Buying human review from service-provided linguists after translation; translating from scratch is outside this fit.Localize.io tour source ↗
StrongPre-translate with MT or AI ↗

Submits strings or files for AI translation; configured or order-selected language models translate them with applicable glossary, memory, style and screenshot context.

Condition: Translation languages, content types and models are constrained by account/project configuration; human review is a separate optional route.Localize.io homepage source ↗
PartialReport localization cost and throughput ↗

Lists delivered-job character counts and prices, with totals by project and API key and monthly cost views.

Condition: Covers delivered volume and cost by project/API key; turnaround and deadline analytics are outside this fit.Localize.io llms.txt source ↗
StrongReuse previous translations ↗

Each string is given exact and semantically similar translation-memory matches; the result identifies whether a remembered translation was kept, corrected or newly written.

Condition: Requires customer-maintained uploaded memory. The model reviews matches and may correct them; unchanged exact-match reuse avoids the per-character charge but still incurs model usage.Localize.io tour source ↗
StrongRun automated QA checks ↗

Runs automated checks for returned strings, placeholders, tags, length limits, line breaks and terminology, with failed strings retried and remaining failures flagged.

Localize.io tour source ↗
PartialRun multi-step review workflows ↗

The documented API workflow has a translation job followed by a separate review job naming a person; the reviewer approves or corrects each string and automated checks run again.

Condition: The caller submits a separate human review job after translation; this fit covers that two-step sequence.Localize.io tour source ↗
PartialSource and onboard linguists and vendors ↗

Onboards the customer’s own reviewers by name, email, language pairs, rate and optional project; reviewers sign in and see their assigned review work.

Condition: Onboards known reviewers for assigned work; recruiting and vetting are outside this fit.Localize.io OpenAPI specification source ↗

Overview

Optional human reviewers can be assigned to review jobs.

Buying context

Fit and constraints

Best for
Teams integrating configurable AI translation and optional human review into a localization pipeline through API or MCP.
Relevant constraints
  • Requires an account API key and configured languages, content types and models.
  • Glossaries, translation memories, style guides and screenshots are customer-supplied assets. Approved translations do not automatically update the uploaded translation memory.
  • Custom connectors, white labeling, on-premises deployment and own model options are presented as Enterprise arrangements.
