Users can now pick the language AI uses for captions, hashtags, descriptions, AND on-image / on-screen text — independent of the app UI locale. A user with pt-BR UI who writes for an English audience gets English content, and vice versa. - New content_language column on workspaces (added to the existing create_workspaces_table migration since we're pre-production), defaulting to 'en'. Fillable on the model. - Dropdown in Settings → Workspace → Brand, side-by-side with Tone. Options: English, Português (Brasil), Español. Short helper copy explains what the setting controls. - Validation: sometimes|string|in:en,pt-BR,es — optional on update so existing callers that don't post the field keep the current value (DB default handles fresh workspaces). - System prompt now uses $content_language (sourced from the workspace) instead of app()->getLocale(). The rule was also strengthened: the AI must always write in this language regardless of what language the user types instructions in, and must instruct image/video tools to render on-media text in this language too. - Image and video Blade prompts received a new line forcing any text rendered inside the generated media to use $content_language. - GenerateImage tool and VideoGenerationService pass the workspace's content_language into their respective prompt templates. Previously the caption would be in Portuguese (since it followed the user's input language) but the image could render with English text because there was no explicit constraint. Now the whole pipeline is aligned to one per-workspace language.

Generate an AI image and attach it to the current post.
|
|
|
|
Call this when the user asks for an image, photo, carousel slide, or any visual content.
|
|
Pass a detailed visual prompt describing what to generate, and an orientation:
|
|
- "vertical" (9:16) for Instagram Reel/Story, Pinterest, TikTok, YouTube Shorts
|
|
- "horizontal" (16:9) for X/Twitter, LinkedIn, Facebook
|
|
|

The image is generated, stored on the public disk, registered in the workspace's

media library, logged in monthly usage tracking, and attached to the assistant's
