Questions about translating large files with AI Glot
What does AI Glot translate?
AI Glot translates large files and returns the same format it received. It supports documents (Word, PowerPoint, OpenDocument, InDesign, EPUB, Markdown, HTML and plain text), CSV and Excel spreadsheets, subtitles and lyrics (SRT, WebVTT, ASS, TTML and LRC), and localization formats such as XLIFF (including Trados, memoQ and Phrase), JSON, JSON Lines, ARB, YAML, TOML, PO, Fluent, Android XML, iOS strings, String Catalogs, Java properties, INI, PHP language files, RESX, XML and Qt Linguist. ZIP bundles of one format are supported too.
How does AI Glot maintain quality across a large file?
You describe the audience, tone, terminology, target languages, and any file-specific rules in plain language. AI Glot combines those instructions with your workspace glossary and applies that context throughout the translation job instead of treating every row as an unrelated prompt.
Can I review the plan before translation starts?
Yes. AI Glot analyzes the file first and prepares a reviewable scope with the content to translate, target languages, word volume, and estimated credit cost. You approve that plan before the full translation runs.
Can I translate a ZIP file?
Yes, when the ZIP contains files from one supported family, for example a folder of SRT subtitle files. AI Glot processes the files together and returns a translated bundle.
Can I use a glossary and custom instructions together?
Yes. Your glossary keeps approved terms consistent across projects, while batch instructions let you describe what this particular file needs, such as tone, audience, protected names, or fields to exclude.
Why not upload a large file directly to a general AI assistant?
General AI tools can work for a small sample. Large production files need a repeatable workflow: analyze the whole file, apply the same terminology and instructions throughout it, show the translation scope before launch, track progress, and return a usable file. AI Glot is built around that job.
Is human review still useful?
Yes. AI Glot produces a first-pass translation at scale, so your reviewers start from a translated file instead of a blank one. Have a human review legal, regulated, or flagship customer-facing text.
