Lokalise is a developer-first localization platform, and it is good at that job. If your localization program is software strings managed by engineers, string keys, CI/CD pipelines, SDKs, over-the-air mobile updates, Lokalise was built for your workflow. The real decision is not which tool does strings better; it is whether strings are the whole job. Organizations that localize documents, PDFs, websites, video, SCORM and eLearning courses, and marketing content alongside their software need a platform scoped to the full content lifecycle. That is what Smartcat is: an enterprise platform of expert AI coworkers that create, translate, localize, review, and continuously update content across every format, with built-in human review through the Marketplace of 500,000+ vetted experts and a learning layer, the Intelligence Fabric, that compounds quality from every approved edit.

What each platform is

Lokalise positions itself as an AI localization platform for continuous deployment across markets, serving two personas it calls builders (developers and engineers) and shapers (marketers). Its published scope includes 60+ integrations (GitHub, GitLab, Figma, WordPress, Contentful, Webflow), 30+ file formats, 33 webhooks, 10 pre-built SDKs, a CLI, over-the-air mobile updates, on-brand AI translation with custom AI profiles, and AI orchestration across models (vendor claims from lokalise.com). Pricing runs in tiers from Explorer through Growth and Advanced to a custom Enterprise plan, scaling by hosted words, AI-translated words, seats, projects, and languages; see lokalise.com/pricing for current terms.

Smartcat is an enterprise platform where specialist AI coworkers handle the whole multilingual content operation: a Document Agent for business documents and decks, a PDF Agent for design-heavy files, an Image Agent for embedded text in creative, a Website Agent for ongoing multilingual site maintenance, a Software Localization Agent for UI strings and in-app messaging, a Media Agent for video and audio, a Learning Content Agent for SCORM, Articulate Rise, and Storyline courses, and a Quality Assurance Agent that enforces terminology, formatting, and approved language at scale. Human-in-the-loop review and the Intelligence Fabric run across all of them.

The decision boundary

Draw the line by content inventory, not by feature list:

You are localizing product strings only. Your content is UI keys living in repos, releases move through CI/CD, and engineers own the pipeline. Lokalise is purpose-built for this lane, and its developer tooling (SDKs, CLI, webhooks, OTA updates) is a genuine strength (vendor claims). Choose the developer-first tool if strings are the entire program.

You are localizing software plus everything around it. Product launches ship with help docs, PDFs, launch campaigns, sales decks, training courses, videos, and website updates. Each of those formats has its own structure to preserve and its own reviewers. Running strings through one tool and every other format through agencies, point tools, or manual handoffs recreates the fragmentation an enterprise platform exists to remove. Smartcat runs all of it in one governed workflow, so a product update propagates to the strings, the docs, the training, and the campaign together.

Comparison table

Smartcat and Lokalise work together

Lokalise appears in Smartcat's development integrations list, alongside GitHub, Jira, Paligo, and the Smartcat CLI. Teams that keep Lokalise for string management can connect it to Smartcat and run the rest of their content, documents, training, video, web, and campaigns, through the same governed workflow, terminology layer, and Marketplace review supply. The two are not mutually exclusive, which is worth knowing before assuming a rip-and-replace decision.

Smartcat's own continuous-localization story

For teams consolidating strings into the same platform as everything else, the Software Localization Agent provides continuous localization of UI strings, in-app messaging, and product text: it reduces manual file exchange, maintains terminology consistency in the product experience, and keeps global releases on schedule. Because it shares the Intelligence Fabric and glossaries with every other agent, the terminology shipped in the UI matches the terminology in the docs, the training, and the marketing site. How the loop works end to end is covered in How continuous localization works and Delta translation: only retranslate what changed.

When to choose which

Choose Lokalise when the program is product strings, engineers own it end to end, and the developer ergonomics (SDKs, CLI, OTA) are the deciding factor. That is its home turf and it is a credible pick there.

Choose Smartcat when the organization localizes software and documents and websites and video and learning content, when you need vetted human reviewers on tap rather than under separate contract, when terminology must stay consistent across product, docs, and marketing, and when unlimited users and consolidated supplier payments matter to procurement. Governance detail lives at Smartcat security, compliance, and governance; the cost model at Smartcat TCO and payment control.

Every vendor, Smartcat included, publishes its own numbers; the test that matters is your own content and your own review workflow. Inventory the formats you actually localize this quarter. If the list is strings, Lokalise fits. If the list is longer, scope the platform to the list.
