Welcome to Ollang

Ollang is an AI-native localization platform for video, audio, and document content. The platform orchestrates AI dubbing, subtitle translation, captions, transcription, document and visual translation, and human review workflows in one place — and exposes everything through APIs, an MCP server, an SDK, and agent Skills. These docs cover four ways to integrate with Ollang and a set of user guides for the concepts behind them:

A short tour: account setup, your first upload + order, and where to go next.

How everything connects

REST API, MCP, SDK, Skills, and workflows — when to use each and how they fit together.

Use Cases

End-to-end walkthroughs: AI dubbing, subtitle pipelines, document localization, visual translation, audio description, continuous i18n.

Best Practices

Production guidance: API keys, callbacks, retries, pagination, error handling, folder structure, memory.

API Conventions

Base URL, authentication, request/response format, pagination, errors, and callbacks — in one reference page.

Glossary

Folders, Projects, Orders, Levels, Workflows, Review Gates, LSPs, QC, BYOK, and more.

Troubleshooting

Common errors, debugging callbacks, retries, and what to send to support.

What Ollang Does

Ollang takes a source asset — a video, audio file, document, image, subtitle file, or strings file — and produces high-quality, multilingual, fully reviewable localization outputs.

AI Dubbing

Multilingual dubbed audio and mixed video with optional Lip Sync or Audio Description. TTS-first flows accept a .txt script with no source video.

Subtitle Translation & CC

Generate captions, translate them, and export SRT, VTT, ASS, STL, SCC, DFXP, ITT, DOCX, XLSX, and broadcast-compatible formats.

Document Translation

DOCX, PDF, PPTX, XLSX, HTML, JSON, DITA, mobile strings (.xml, .strings, .stringsdict), AE projects, and JPEG/PNG image-to-image.

Visual Translation

On-screen text inside videos, graphics, and visual assets — preserving layout and positioning.

Human Review

Add a Level 1 review gate to any order to route output to Ollang-managed linguists or your own LSPs and editors.

QC & Analytics

AI QC across accuracy, fluency, tone, and cultural fit; human QC annotations; QC score progression and human-edit-percentage analytics.

​
Pick Your Integration Path

Ollang REST API

Programmatic uploads, orders, projects, revisions, QC, human review, and webhooks. API-key authenticated.

Ollang MCP

Hosted Model Context Protocol server (OAuth 2.0 + PKCE). Drop into Claude, Cursor, Claude Code, Devin, Replit, Windsurf, and more.

Ollang SDK

TypeScript/Node.js SDK for asset scanning, i18n workflows, CMS capture, and a typed REST client.
