What LingoAI does
LingoAI is a localization QA Chrome side-panel extension. It extracts the visible UI strings on a page — including tooltip, aria-label and placeholder text — and has an AI model review them against your target locale, then reports localization defects with a severity, a suggested fix, and screenshots plus on-page overlays that point to each problem. It's built for QA engineers, localization managers and developers shipping multilingual products.
How it works
- Pick a language — open the side panel and choose the target language (e.g. German, Japanese, Spanish).
- Run audit — LingoAI extracts the page's visible text and has an AI model review it against the target locale.
- Read the report — results are grouped by severity, with on-page overlays that point to each issue.
What it catches
- Critical — untranslated strings on a localized page; clipped or overflowing UI (detected deterministically in the live DOM).
- Major — grammar errors and culturally inappropriate phrasing.
- Minor — number, date and currency formatting; spacing and punctuation.
- Deterministic checks — leaked interpolation tokens (
{name},%s), mojibake/encoding issues and locale number formats — no AI guesswork.
Professional QA tooling
Beyond the audit, LingoAI adds contextual screenshots, a multi-page flow recorder, visual error overlays, a pseudo-localization toggle, and export to Jira, GitHub, Markdown and JSON — or turn a recorded flow into a Playwright/Cypress spec. A local history and trend dashboard tracks quality over time. It supports Anthropic, OpenAI and Google Gemini models, selectable in Settings.
Local-first & private
LingoAI is local-first: your API keys, reports and screenshots never leave your device except as direct API calls to the AI provider you choose. The side panel opens for the active tab only.
Who it's for
QA engineers, localization managers and developers shipping multilingual products who need to catch translation and i18n defects before release. It pairs well with autonomous UI exploration from Pathfinder and CSS inspection from StyleSpy. Free on the Chrome Web Store; works in any Chromium browser.
