 ## Translation
 
-Search for **Conjure Translate**, identified by its centered 🌏 icon, and open it. With empty or whitespace-only input, Return or **Swap languages** reverses the source and target without submitting a request. Enter text to change the action to **Translate**; press Return or click it to submit. Typing alone never sends text. When the translation is available, the action changes to **Copy**: press Return or click it to copy the full translation and close Conjure. Command-C still copies selected output. Editing the input clears the result and restores **Translate**, or **Swap languages** if empty. The action is disabled while translating.
+Search for **Conjure Translate**, identified by its centered 🌏 icon, and open it. With empty or whitespace-only source text, Return or **Swap languages** reverses the source and target without submitting a request. **MyMemory** translates the text in one step: press Return or click **Translate** to submit. Typing alone never sends text.
+
+With **OpenAI · gpt-6-luna**, enter the text first, then press Return or **Add context**. The original text stays visible while the search bar becomes a second input for the situation: where you encountered it, who said it to whom, or the intended tone. Press Return or **Translate** to send both inputs. Context is optional; Return with blank context translates without it, rather than swapping languages. OpenAI uses context to resolve meaning, tone, and register, and returns only the translation—not a translation of the context or an explanation. Nothing is sent when advancing to the context step.
+
+When the translation is available, the action changes to **Copy**: press Return or click it to copy the full translation and close Conjure. Command-C still copies selected output. Editing the current input clears the result; editing context keeps the original text. The action is disabled while translating.
 
 The footer places the current primary action and its Return keycap before **Actions**, whose Command and K keys use separate keycaps, matching the launcher.
 
-Press Command-P or click the provider selector to expand a searchable action-style popup from its top edge downwards, hiding the indicator until the popup closes. A checkmark marks the current provider. Use Up/Down and Return or click a provider to select it; Escape, Back, or clicking outside closes the popup. Changing providers clears the previous result without submitting a request.

A checkmark marks the current provider. Use Up/Down and Return or click a provider to select it; Escape, Back, or clicking outside closes the popup. Changing providers clears the previous result without submitting a request. Switching away from OpenAI during the context step restores the original source text; context is not sent to MyMemory.
 
-The footer shows the current language pair (initially **English → Japanese**). Click it or open **Actions** with Command-K to change the source language, change the target language, or swap them. Language choices are saved locally and apply to both providers. Changing languages clears the previous result without submitting another request. The input hint and output accessibility label follow the selected pair. Escape closes an open action/provider picker first and dismisses the window only when no picker is open. Back closes the picker first, then returns to the launcher and restores your search. Command-W always dismisses the entire window.

Command-W always dismisses the entire window.
 
 Editing the input, changing languages or providers, saving or forgetting the key in Settings, or leaving Translate cancels the active request; cancelled results are not shown. After a request fails, submit again to retry.
 
 - **MyMemory:** No account or key required. Limits are 500 UTF-8 bytes per request and [5,000 characters per day](https://mymemory.translated.net/doc/usagelimits.php) for anonymous use.
 - **OpenAI:** Requires an API key, access to `gpt-6-luna`, and sufficient API billing. Manage the key in **Settings > Conjure Translate**: **Save Key** stores it in macOS Keychain; **Forget Key** removes it. Translate never saves a key implicitly. Requests disable API response storage, but OpenAI's retention policies still apply.
 
-**Translation sends your input to the selected third-party provider. Avoid sensitive content.** There is no automatic fallback between providers. MyMemory never receives your OpenAI key.
