Overview: What Is Translation Agent?
Translation Agent is a built-in Jasper agent that translates marketing content into 27 supported languages. It's designed to produce output that reads as if it was originally written in the target language — rather than simply converted from the first written language.
What sets it apart from generic translation tools:
- Glossary enforcement — Your brand glossary is loaded from the Knowledge Base and enforced throughout the entire pipeline. Product names, industry terms, and branded language stay consistent across every language, every time.
- Brand voice — Jasper IQ applies across all languages, keeping tone, style, and audience alignment consistent with your brand.
- Style-first translation — Before translating, the Agent analyzes your content and generates native-language writing samples as style anchors, so the output reflects how native speakers in your market actually write.
- Editorial review — A dedicated review phase reads the translation without the source document and flags anything that sounds translated rather than natively written. A final refinement pass applies the feedback and strictly enforces every glossary term.
- Built for marketing content — Purpose-built for campaigns, web copy, sales materials, and product content.
You can use Translation Agent in Canvas for single-document translation, or as a column in Jasper Grid to run translations at scale across many rows simultaneously.
How Translation Agent Works
Translation Agent doesn't convert text word-by-word. It uses a five-phase AI pipeline designed to produce output that reads as if it was originally written in the target language.
- Phase 1 — Content analysis: The Agent analyzes your document's content type, tone, register, and audience before a single word is translated.
- Phase 2 — Glossary loading: Your brand glossary is loaded from the Jasper Knowledge Base and prepared for use across the entire pipeline.
- Phase 3 — Style research: The Agent generates native-language writing samples that show how content of this type actually sounds when originally written in the target language. These anchors guide the translation.
- Phase 4 — Translation: A full translation is produced using the style anchors. Your glossary serves as a soft guide at this stage to preserve natural flow.
- Phase 5 — Editorial review and refinement: A native-speaker editorial persona reviews the translation without seeing the source document — specifically to catch anything that sounds translated rather than written. Glossary compliance is verified, and a final pass applies all feedback and strictly enforces every glossary term.
The result is copy that reads as if it was created for that market.
Using Translation Agent in Canvas
Translation Agent in Canvas is ideal for translating a single document. Attach it in Chat and prompt the agent with a target language — Jasper outputs the translated content directly into your Canvas.
Set up your files
- If you have specialized terms that need consistent translation, upload a glossary file to your Knowledge Base. The file name must include the word "glossary" so Jasper can automatically detect it.
- Upload the document you want to translate to your Knowledge Base as well.
Keep in mind: You can only use one glossary file at a time. Combine all your terms into a single master glossary document before uploading.
Translate a document
- Navigate to your Project > Chat.
- Select the default agent, then switch to Translation Agent.
- Attach your document from the Knowledge Base.
- Use a prompt like: "Translate the attached document to Finnish."
Jasper generates the translated output directly into your Canvas.
Using Translation Agent in Jasper Grid
The Translation Agent column lets you translate content at scale — running translations automatically across every row in a Grid. Each column takes two inputs you configure: a source column and a target language.
Add a Translation Agent column
- Open any Grid and click + Add column.
- Select Translation Agent from the agent section.
- Configure the column:
- Source column — choose any Text, Prompt, App, or Knowledge column to the left. This is the content that gets translated.
- Target language — choose from 27 supported languages, or point to a Text or Dropdown column if the language varies per row.
- Give the column a name and click Add.
- Run the row — translated output appears per row, just like any other agent column.
Add a glossary (optional)
If you want Jasper to respect specific term mappings during translation:
- Add a Knowledge Base column to your Grid and attach your glossary file. The file name must include the word "glossary."
- In your Translation Agent column settings, reference the Knowledge Base column as the glossary source.
This is especially useful for running branded or technical translations at scale across multiple assets.
Supported Languages
Translation Agent supports 27 languages, including Chinese (Simplified and Traditional), Japanese, Korean, Arabic, Hindi, and major European languages including Spanish, French, German, Italian, and Portuguese. To see the full list, open the target language selector when setting up your Translation Agent column or Canvas workflow.
Limitations
Keep these in mind when using Translation Agent:
- No dedicated glossary UI — Glossaries are stored as text files in the Knowledge Base. Flexible formats are supported (comma-separated, arrow notation, pipe-separated, free-form text), but there's no spreadsheet-style editor.
- One language per run in Canvas — Run a separate session for each target language. In Grid, add one Translation Agent column per language.
- No regional dialect picker — The UI doesn't have a dialect selector. You can specify a regional preference in your prompt (e.g., "Translate to Brazilian Portuguese").
- Document size limit — Knowledge Base items support up to 100,000 characters (~20-30 pages). Very large documents are automatically split into chunks for processing.
- Unsupported file types — Image files and spreadsheets (CSV, Excel) cannot be translated. PDFs, Word docs, audio, video, and URLs are all supported.

Translation Agent is available in Canvas and Jasper Grid on Business plans.
