Everything you need for translation QA

Lightweight review workflows that sit downstream of Phrase, Lokalise, or your own export — without replacing your TMS.

Side-by-Side Review

Align source and target segments in a synchronized view. Mark each row as approved or needs revision — no more switching between two windows.

Terminology Guard

Upload a glossary CSV. Flag forbidden terms and inconsistent translations before they reach production.

Locale File Diff

Upload JSON locale files. Instantly surface missing keys, extra keys, and untranslated strings.

QA Reports & Handoff

Export issue summaries as CSV or PDF. Share read-only review links with translators, PMs, and stakeholders.

From export to sign-off in minutes

Works with content exported from any TMS, spreadsheet, or locale file in your repo.

1

Import

Paste text, upload CSV/XLSX, or drop JSON locale files. Map source and target columns in one step.

2

Review

Scan aligned segments with auto-checks for empty targets, variable mismatches, and glossary violations.

3

Ship

Export a QA report, share with your vendor, and merge with confidence.

Frequently Asked Questions

No. LingoCompare is a QA and review layer. Keep using Phrase, Lokalise, Crowdin, or your own workflow — export strings, run QA in LingoCompare, then push fixes back through your existing pipeline.
CSV and XLSX for spreadsheet exports, JSON for locale files (e.g. en.json + zh-CN.json), and plain-text paste for ad-hoc copy review. PO and XLIFF support is on the roadmap.
LingoCompare does not machine-translate your content. Uploaded project data is stored securely for review and can be deleted on request. We do not sell your data. Enterprise customers can inquire about data processing agreements.
