The problem
Voice dictation has been around for decades, but it still doesn’t work for professional communication. You speak a paragraph and get back a mess. Punctuation is wrong. Formatting is missing. The tone doesn’t match the app you’re writing in. So you spend 10 minutes editing what should have taken 30 seconds to say.
Every other tool in the space is solving this by adding more AI. They rewrite your sentences. They suggest better phrasing. They generate content on your behalf. We think that’s the wrong direction.
Our approach
Rubil is a ghostwriter, not a generator. You speak. We format. Your vocabulary, your tone, your ideas — we clean up the structure, fix the grammar, and adapt the formatting to the platform you’re writing in. Gmail gets email structure. Slack gets concise messages. Notion gets clean prose. Same voice input, different output.
Your words stay yours.
How it works
Chrome Extension
One click to install. Rubil lives in your browser and works in every web app — Gmail, Slack, Notion, Google Docs, and 20+ more. Text appears directly in the field you’re writing in.
Mac Desktop App
A lightweight menu bar app with a global hotkey. Works in native Mac apps like Apple Mail, Slack desktop, VS Code, and Claude desktop. Same formatting engine, same glossary.
Your Glossary
Rubil learns how you speak. Add names, acronyms, technical terms, and text expansions with custom rules. Your glossary syncs across Chrome and Mac.
Why we stay focused
Every voice dictation tool in the market is racing to add more AI. More rewriting. More generation. More features that think for you. Rubil goes the other direction. We do one thing — format your speech for the app you’re writing in — and we do it better than anyone else. That focus is intentional. It’s what lets us ship faster, stay privacy-first, and keep the product simple enough that it disappears into your workflow.
