Two screenshots found in Gboard beta 18.0.3 show Rambler can switch between Standard and Rambler dictation, with deeper settings tied to each mode.
One screen indicates Rambler can use a user’s existing Gboard dictionary, while a separate Rambler Dictionary stores words learned from voice typing—suggesting it may pick up slang over time.
Google’s support page adds that Rambler also works offline, but without advanced stylistic rewrites or complex conversational voice editing; basic punctuation, cleanup and capitalization still remain available.
The same support page says Rambler will face usage limits, though Google has not explained whether caps block the feature entirely or push users to the offline mode.
Rambler is part of Gemini Intelligence on compatible Android phones, but the teardown reflects work-in-progress code that may change before any public release.
