Rubil is a ghostwriter, not a generator
Rubil formats your words. It never rewrites or generates them.
A ghostwriter writes in your voice, never their own. That is the whole idea behind Rubil. You speak, and Rubil shapes what you said into clean, finished text for wherever you are writing. The thinking stays yours. The words stay yours.
What Rubil does
Rubil fixes grammar, adds punctuation, drops the filler from natural speech, and formats the result for the platform you are in. The same sentence becomes a structured email in Gmail, a short message in Slack, and clean prose in a document. The structure changes to fit the place. The meaning does not.
What Rubil does not do
Rubil does not invent sentences or rephrase your point into something smoother. It does not generate content from a prompt. If you did not say it, Rubil does not write it.
Who this is for
Some people want a tool that writes for them. Rubil is for the people who want to write for themselves and skip the typing. If you care that the words coming out are the words you meant, you do not want a tool that generates them for you.
Rubil only knows the words you teach it
Rubil does not study how you write or build a profile of your style. It knows the names, acronyms, and terms you use because you put them in your Glossary. You teach it. It does not watch you.
How Rubil differs from the rest of the category
Most voice tools are adding more generation, not less. Wispr Flow's Command Mode rewrites your sentences on request. Willow Voice's AI Mode turns rough notes into polished messages. Aqua Voice offers editing commands that restructure what you said. These are real features, and for someone who wants the AI to do the writing they are the right call. Rubil goes the other way on purpose. It is the dictation tool that writes in your words, not its own.
Common questions
Does Rubil change my wording?
No. Rubil corrects grammar and adds formatting. It does not swap your words for its own or rephrase your sentences.
Is Rubil an AI writing assistant?
No. AI writing assistants generate text from a prompt in the AI's words. Rubil formats text you already spoke, in your words.
Does Rubil learn my writing style over time?
No. Rubil only knows the words you teach it through your Glossary. It does not observe your dictation or build a style profile.
Your words, formatted for wherever you write. Never rewritten, never generated.
