What to know

Gemini’s reusable Styles are gaining controls for names, colors, fonts, behavioral guidelines, references, and deletion.
The controls would let you refine an existing Style and direct how Gemini crafts your media.
We found the dormant code in Google app v17.61.19.sa.arm64, but could not surface the controls in the app.

Google already publicly documents custom visual styles in Gemini Notebook, while reusable Styles have appeared in the Google app’s code since August 31, 2026, when we found the feature in v17.54.10.sa.arm64.

Now, our teardown of Google app v17.61.19.sa.arm64 shows an update to that existing feature. The latest strings add a detailed editing workflow for reusable Styles, along with a way to delete them. The code is dormant, and we could not surface these controls in the app.

Gemini Styles are getting detailed editing controls

The clearest addition is an edit dialog titled “Edit @%1$s details,” with the placeholder preserving the individual Style name. Inside it, the code references separate controls for editing the Style’s name, colors, fonts, and guidelines.

The guidelines field goes beyond visual formatting. Its helper text says it can instruct how Gemini crafts your media, while the placeholder asks for the “behavior, style, and tone” of the Style. Separate “Do” and “Don’t” labels suggest these instructions can define both desired and unwanted behavior.

References also receive their own section, alongside empty-state messages for colors, fonts, guidelines, and references. Together, these strings point to a reusable configuration that can hold creative direction and supporting material, rather than a one-off visual choice.

assistant_robin_collection_detail_edit_dialog_title = “Edit @%1$s details”

assistant_robin_collection_detail_edit_name_label = “Style name”

assistant_robin_collection_detail_edit_colors_a11y = “Edit colors”

assistant_robin_collection_detail_edit_fonts_a11y = “Edit fonts”

assistant_robin_collection_detail_edit_guidelines_label = “Guidelines”

assistant_robin_collection_detail_edit_guidelines_helper = “Instruct how Gemini crafts your media”

assistant_robin_collection_detail_edit_guidelines_placeholder = “Set the behavior, style, and tone of your style”

assistant_robin_collection_detail_guidelines_do = “Do”

assistant_robin_collection_detail_guidelines_dont = “Don’t”

assistant_robin_collection_detail_references_header = “References”

assistant_robin_collection_detail_edit_save_button = “Save”

assistant_robin_collection_detail_edit_error = “Failed to update style”

Styles can also be permanently deleted

This build adds a “Delete style” menu option backed by a confirmation dialog. The warning says deletion cannot be undone, and the supporting strings include explicit cancel and delete actions as well as an error message for a failed deletion.

That workflow makes this more than a collection of descriptive labels. The code outlines the practical controls needed to revise, save, and remove a reusable Style after it has been created.

assistant_robin_collection_detail_menu_delete = “Delete style”

assistant_robin_collection_detail_delete_dialog_title = “Delete style?”

assistant_robin_collection_detail_delete_dialog_body = “Are you sure you want to delete this style? This cannot be undone.”

assistant_robin_collection_detail_delete_cancel_button = “Cancel”

assistant_robin_collection_detail_delete_confirm_button = “Delete”

assistant_robin_collection_detail_delete_error = “Failed to delete style”

These editing and deletion controls are not available to users yet; we’ll watch future Google app builds for their rollout.
