Our Multilingual Editing & Translation Review service supports a wide range of cross-language editorial needs. Typical projects include:

• Translated research articles that need to be polished for journal submission

• Policy briefs and white papers originally written in another language and translated into English

• Bilingual exhibition texts and catalogues for museums and cultural institutions

• Grant proposals and reports created by nonprofits working in international contexts

• Web and outreach content translated for global audiences

• Artist statements and program materials written in English as a second language

• Book manuscripts or chapters translated into English from Spanish, French, German, and other supported languages

All projects are reviewed by editors with bilingual-level fluency who ensure clarity, tone, and consistency while preserving the original message and intent.

Not every multilingual project requires the same level of editorial attention. We offer flexible editing services—ranging from light reviews of translated text to in-depth editing and restructuring of multilingual materials. Our editors have bilingual-level fluency and tailor their review to your goals, source material, and audience.

We can work in either the source language, the target language (English), or both—depending on what your project needs.

Here’s what our editorial levels typically include:

Translation Review
We compare the source and target texts to ensure the English version is accurate, fluent, and preserves the original meaning. This review checks for mistranslations, omissions, and awkward phrasing.

Line Editing
A deeper edit focused on tone, clarity, sentence structure, and overall readability of the English text. We ensure the translated version sounds natural, matches your intended audience, and flows as if originally written in English.

Copyediting
A lighter edit that focuses on grammar, punctuation, spelling, formatting, and style consistency (Chicago, APA, house style, etc.). Best for well-translated drafts that need technical polish.

Proofreading
The final stage before publication. We catch lingering typos, formatting issues, and small errors in English-language translations—typically after layout or typesetting.

If you’re unsure what level your document needs, we’re happy to assess it and recommend the right service for your timeline and goals.

Our pricing reflects the depth of review your AI content requires. Light oversight is ideal for a quick polish, while standard and intensive tiers deliver deeper editorial refinement. We’ll provide a clear estimate before work begins, so you can plan confidently. Contact us for a custom quote tailored to your project type and volume.

Multilingual editing is most effective after your translation is complete but before it’s shared with your audience. Whether your content was translated by a professional, a team member, or an AI tool, Flatpage’s editors step in to ensure the final product is clear, accurate, and ready for publication.

We recommend this service at key stages in your content lifecycle:

Pre-publication: Before publishing bilingual reports, exhibition materials, books, or web content.

Pre-submission: Before submitting translated proposals, grant applications, academic articles, or donor materials.

Pre-review: Before sending drafts to funders, internal stakeholders, or peer reviewers for feedback.

Pre-launch: Before releasing campaign content, newsletters, press releases, or digital materials in multiple languages.

Flatpage’s multilingual editing provides the final layer of review to ensure your translated content reads fluently, respects your organization’s voice, and resonates with your audience—no matter the language of origin.

Turnaround times depend on the length of your document, the level of editing required, and whether we’re reviewing both the source and target language. Most projects are returned within 5–10 business days, but we offer faster options for shorter documents or time-sensitive requests.

Typical turnaround windows:

• Short documents (1–5 pages): 3–5 business days

• Medium-length documents (6–25 pages): 5–7 business days

• Longform projects (26+ pages): 7–10+ business days, depending on complexity
