Voice dictation for consultants: get billable time back without losing your voice.
Dictate client emails, engagement updates, and deliverable drafts across every platform. Your Glossary keeps client names, project codenames, and industry acronyms right the first time.
Your calendar is a wall of client calls, and the space between them is writing. Status emails to three engagements, a Slack thread for the internal team, deliverable edits in a Google Doc that has to go out by Friday, and a follow-up note to a partner who is waiting on your answer from yesterday. Every hour you spend typing is an hour you are not billing, or an hour you are billing at cost against your own margin. For a consultant, that ratio between thinking work and administrative writing is the whole game, and administrative writing keeps winning.
Voice dictation should fix this. Talk instead of type, clear the backlog between meetings, get a working draft of a memo down before you sit at the keyboard. But when you try it, a different problem shows up. Your client is called Vercel, not Versal. The engagement is Project Odyssey, not project Odysseus. The acronym is EBITDA, not "a bit dot" or "e-bit-a." You dictate a two-paragraph update and then spend three minutes editing names and acronyms out of the transcript. The tool cost you the time it was supposed to give back.
Rubil is voice dictation built for people who write across many platforms all day. It runs as a Chrome extension for browser work and as a Mac desktop app for native apps. Same voice input, different output for Gmail vs Slack vs Jira. It formats your words. It never rewrites or generates them. Your ghostwriter, not your ghost-thinker. That distinction matters more for consultants than for almost any other role, because a client can tell when an email was written by an AI, and it changes what they think of you.
A day of consulting, dictated.
Here is a typical Tuesday morning. You have a client status call at ten and a deliverable review after lunch. Between them, you owe a recap email to the client, three Slack replies to your engagement manager, a two-page memo section in a Google Doc, and a comment on a Jira ticket for the tech workstream. In a typing morning, that is forty-five minutes of writing, minimum. In a dictating morning with Rubil, it is closer to ten, and none of it lands wrong.
Here is what dictating the recap email looks like. You open Gmail, hit reply on the thread, click the Rubil mic, and talk the way you would if you were leaving a voicemail for a colleague. Say this into Rubil:
Hi Priya um wanted to close the loop on the the OKR workstream we agreed to move the the North Star metric review to next Thursday and I I asked Marcos to pull the the APAC numbers from the Q3 dashboard before then also uh regarding the pricing tier analysis I think we can we can push the draft to Friday if you're okay with that let me know
What appears in the Gmail compose window:
Hi Priya,
Wanted to close the loop on the OKR workstream. We agreed to move the North Star metric review to next Thursday, and I asked Marcos to pull the APAC numbers from the Q3 dashboard before then.
Regarding the pricing tier analysis, I think we can push the draft to Friday if you're okay with that. Let me know.
Client name spelled right. Acronym right. Colleague name right. Project workstream name right. Greeting, paragraph breaks, a tone that reads like an email and not a wall of speech. That is Rubil in Gmail. The same words in Slack would land as a shorter, chatty version without the greeting and closing. The same words in Notion would land as document-style prose. Rubil detects which app you are in and formats for that app, so you never have to think about it.
You can try this in your browser first, nothing to install. Speak one short message and Rubil shows the Gmail and Slack versions side by side, so you can see the app-shaped output before you set anything up.
Why consulting communication is different.
A consultant is not a person with one job. You are on three or four engagements at once, and every engagement has its own private language: client codenames, industry acronyms, contact names, format preferences, and the tone the account lead wants in status updates. Some clients want weekly memos in a fixed template while others want a rolling Slack thread, and switching between engagements means switching vocabulary several times a day.
Rubil is different because you teach it your world instead of hoping it guesses. The Glossary is where that teaching lives, and it is the single feature that makes voice dictation viable for client-facing work.
The Glossary, engagement by engagement.
The Glossary is a personal vocabulary layer on top of the voice engine. You add the People you write to and about, the Acronyms specific to your engagements and industries, the Terms with strict spellings and casing, and the Expansions that turn a short trigger into a full block of templated text. Every entry syncs between the Chrome extension and the Mac app. There is no entry limit.
For a consultant, People and Acronyms are the two categories that pay for themselves in the first day. Add every partner, engagement manager, client contact, and cross-functional counterpart you write to. Add every industry acronym you use routinely, EBITDA and SG&A and TAM and the ten others specific to your practice. Rubil will place them correctly across every message, every deliverable, every ticket.
Expansions are where the time compounds. If every weekly client update follows the same structure, save it as an expansion triggered by "weekly update" and Rubil drops the whole scaffold into whatever app you are in. Save your standard project intro paragraph, or the meeting-notes template your firm uses, or the engagement kickoff outline that has to go out at the start of every new project. Any block of text you write more than once a week belongs in the Glossary as an expansion.
Rubil notices when you correct the same word more than once and offers to add it to your Glossary. You are not maintaining a spreadsheet. Your vocabulary fills in as you work.
Chrome extension or Mac app.
Most consultants use both. The Chrome extension covers Gmail, Google Docs, Slack in the browser, Notion, Confluence, Jira, Linear, Asana, and any other web app your clients or your firm run on. The Mac app covers the native Slack client, Apple Mail, Microsoft Word, Notes, and any other Mac app with a text field. Same Glossary, same formatting engine, same backend. Install both, log in once, and dictate anywhere.
Why not the alternatives.
Wispr Flow, Willow Voice, and Aqua Voice take the opposite approach: they use AI to rewrite your voice input into a polished version. For a consultant whose credibility is tied to how they sound in writing, that is a different bet. If you want to make that trade, our comparison posts break down the differences honestly: Rubil vs Wispr Flow, Rubil vs Aqua Voice, Rubil vs Willow Voice.

Quick tips for the first week.
Add the ten people you email or Slack the most, three per current engagement, and the five acronyms you use every day. That gets you to about 80 percent accuracy on your typical week without another minute of setup. Turn on auto-suggestions and let the rest fill in on its own.

FAQ
What is the best voice dictation tool for consultants in 2026?
The best voice dictation tool for a consultant is one that handles a lot of client-facing writing across many apps without rewriting your words or getting your client's names wrong. Rubil is built for that. It runs on both Chrome and Mac, formats output per app so a Gmail draft looks like an email while a Slack draft looks like a chat, and gives you a personal Glossary where you teach it every client contact, engagement codename, and industry acronym so they land correctly the first time. Wispr Flow, Willow Voice, and Aqua Voice are the funded alternatives, and they take a different approach by using AI to rewrite your input into a polished version. For consultants who prize sounding like themselves in client writing, Rubil is the fit.
Is voice dictation safe for confidential client work?
Rubil is designed for confidentiality-sensitive writing. Audio is processed transiently through Groq and discarded after transcription. Transcripts are sent to OpenAI for formatting and are not stored on Rubil's servers. The Glossary is encrypted locally and in the cloud. Rubil never reads your screen or takes screenshots. The app detects which platform you are in from the browser URL on Chrome or the app bundle ID on Mac, not from any content you are writing. Every data processor is named on our privacy page. Consultants working under NDA or on sensitive engagements can adopt Rubil without introducing a new place their work is stored.
Can I keep separate vocabularies for different clients?
You maintain one Glossary that spans all your engagements, and it is large enough to cover every client without collision. Add every client contact, every engagement codename, and every industry acronym across every active project. The Glossary has no entry limit, so you never have to prune. Acronyms have platform-aware behavior: "OKR" can stay as "OKR" in a Slack message where your team knows what it means, and expand to "Objectives and Key Results" in a client email where the reader might not. What Rubil does not have yet is a per-client partition where the same word means one thing for Client A and another for Client B. If you hit that case, use distinct terms in the Glossary rather than reusing an ambiguous one.
Does Rubil work in the apps consultants use every day?
Rubil covers the apps that dominate consulting work. On Chrome: Gmail, Google Docs, Slack in the browser, Notion, Confluence, Jira, Linear, Asana, and any other web app you write in. On the Mac desktop app: the native Slack client, Apple Mail, Microsoft Word, Notes, and any other Mac app with a text field. Both share the same Glossary and formatting engine, so you install once and dictate anywhere.
How much time does voice dictation save a consultant per week?
It depends on how much of your workweek is writing. If you send 100+ messages a day across Gmail and Slack and draft deliverable copy on top of that, the time back is measured in hours per week, not minutes. If most of your day is calls and analysis with light writing in between, the win is smaller and more about staying in flow than saving clock time. Once your Glossary is built out, the correction pass on names and acronyms goes close to zero, which is where most of the felt speedup comes from. Two weeks of daily use is usually enough to know if voice dictation is worth it for your specific workload.
For consultants, writing is the delivery vehicle for the thinking. Rubil gives you back the time between the meetings without changing how you sound to the people who pay for the thinking.
