Lingo · Translate & Write

Translate and write with your own API. Optional automatic checks, inline suggestions, a personal dictionary and refinements.

Lingo brings translation and writing tools next to your text. Select text to translate, proofread or rewrite using your own OpenAI or Responses API-compatible service and model. New in 1.1.2: A clearer suggestion card puts the explanation above a replacement button. Click the replacement or press Enter to accept; dismiss, dictionary and full-list controls remain available. Also included: The check button appears only when there are suggestions by default. Choose always hidden or show with text in settings; empty fields always hide it. Right-click a field to check its text, or right-click a selection to proofread directly. Hiding the button does not disable automatic checks or underlines. Writing features: - Word-level red underlines for grammar, spelling and contextual word-use suggestions; optional green underlines for style. Hover to inspect, then accept or dismiss. - Optional automatic checks, with a global default for authorized websites and per-site overrides. Off by default. Once enabled, entering a supported editor or pausing after typing sends its entire current text for checking. - A personal dictionary for names, brands and specialist words. Grammar and contextual word-use checks still apply. - Custom rewriting presets, result/comparison views, and an expandable rewriting conversation based on the latest result. See the latest request and answer by default, scroll upward for history, and copy or replace with the latest complete result. - Words and phrases: parts of speech, meanings, usage, collocations and bilingual examples. - A six-step setup guide, a local practice exercise with no API calls, and a skippable upgrade introduction that preserves existing settings. Revisit any topic through Introduction in settings. Move or resize the webpage panel and edit the source. Ordinary text fields and simple rich text support explicitly confirmed replacement and undo. The full suggestion list can locate the original text and remain open for successive corrections. In text-based PDFs, use the selection context menu and sidebar. For Google Docs and complex editors, paste into the sidebar and copy the result; direct replacement is not supported. English, Simplified Chinese and Traditional Chinese interfaces are available. Translation targets are independent. Use Enter to accept a suggestion or send a refinement, and Shift+Enter for a new line in the refinement composer. Requires Chrome 120+, a valid API key, compatible model and available quota. The extension is free to install; API usage is billed separately by your provider. No API credits are included. Requests go directly to the configured service and may include private communications such as email drafts. Check the destination before enabling automatic checks. The developer operates no relay and includes no advertising, analytics or text history. Provider retention policies apply. Review generated suggestions before using them.
