Why not just
use AI to translate?
Honestly? For small projects, you should. AI translation is fast, cheap, and increasingly good. We've built it directly into Locize for exactly that reason.
The question is not whether AI can translate your strings. It's whether AI can manage them across a team, over time, without developer involvement for every change.
AI translates strings
Given a string in English, Claude or ChatGPT produces a string in French — in any of 95+ languages, with i18next placeholders intact. Quickly, cheaply, usually well. This is genuinely solved. Use AI for this; we do.
A TMS manages them
Which keys changed since last week? Which languages are incomplete? How do you push a copy fix without a deployment? Who can edit translations without touching the repo? These are system problems. AI doesn't solve them.
Where the DIY workflow breaks down
Six problems that appear when a real product grows past the initial translation sprint.
Key lifecycle management
Context and consistency
Deploying a translation fix
Non-developer access
Audit trail and history
Staging vs. production
Already all-in on AI? The graduation path
You don't have to throw away your LLM pipeline. Graduating means keeping AI as the translator and adding the management layer around it, in four steps.
This is the failure mode that made headlines when Mozilla moved its support content to AI-first localization and its long-standing Japanese volunteer community resigned: the criticism was not that AI translated, but that nothing enforced terminology and style. The fix is governance, not better prompts.
Keep your AI, give it context
Bring your own OpenAI, Gemini or Mistral key (or use the built-in service). Locize feeds your glossary and styleguide into every prompt, so terminology stops drifting.
Score every AI translation
Quality Estimation rates each AI translation from 0 to 1. Confident results are saved directly; low-confidence ones are routed to human review instead of shipping silently.
Review what matters, with a trail
Reviewers work in context on the running app. Accept/decline history and provenance export show who approved what, when, and with which quality score.
Ship over the CDN
Approved translations publish to a global CDN without a redeploy. Your CI pipeline stays; the copy-paste step goes.
