Introducing FluidVox: Voice Typing That Works in Every App

Voice typing has been around for years, but the output has always felt like a rough draft. You speak clearly, and what you get back is a wall of text with no punctuation, misspelled names, broken grammar, and a tone that doesn't match where you're writing. You end up spending more time fixing the transcription than you would have spent just typing it.

We built FluidVox to solve this. It's a macOS menu bar app that turns your voice into polished, ready-to-send text — directly inside whatever application you're already using. No window switching. No copy-pasting. You hold a key, speak, and your words appear right where your cursor is — in Slack, in Gmail, in VS Code, in Notion, anywhere.

AI that actually understands what you mean

The single biggest thing that sets FluidVox apart is what happens after your voice is captured. Powered by the latest large language models, FluidVox doesn't just transcribe your words — it understands them. The AI corrects your spelling, fixes grammar mistakes, adds proper punctuation and capitalization, removes filler words like "um" and "uh", cleans up false starts and repeated phrases, and delivers text that reads like you sat down and carefully typed it out.

This is the difference between a raw transcription and something you can actually send. When you say "so uh basically I think we should probably move the meeting to like thursday if thats ok with everyone", FluidVox outputs "We should move the meeting to Thursday if that works for everyone." — clean, punctuated, and ready to go.

The AI also understands context. It knows the difference between "their", "there", and "they're". It capitalizes proper nouns correctly. It handles technical terminology, abbreviations, and domain-specific language without breaking a sweat. And if you build a personal dictionary with your own terms — product names, people's names, acronyms — the AI uses those as hints to get things right the first time.

Fast enough to keep up with your thoughts

The average person types around 40 words per minute. Most people speak at 130 to 150. That's a 3x difference, and it adds up fast across a day of emails, messages, and documentation.

FluidVox is built for speed at every level. Words appear as you speak, streamed in real time. There's no waiting for a "processing" spinner after you stop talking — for short messages, the result appears almost instantly. For longer recordings, you can watch your text build up progressively while you're still speaking. The entire pipeline — capture, transcribe, clean, inject — is optimized to feel effortless.

This speed isn't just about raw words per minute. It's about staying in flow. You don't leave the app you're working in. You don't switch windows or copy-paste from a dictation tool. Your cursor stays exactly where it is, and the text just appears.

Adapts to every app you use

Here's something no other voice typing tool does: FluidVox automatically adjusts its writing style based on the app you're dictating into. The AI understands that a Slack message to your teammate and a client email are fundamentally different kinds of writing, even when the words coming out of your mouth are similar.

Speak into iMessage or Slack, and the output is casual and conversational. Switch to Mail or Outlook, and the same stream of speech becomes polished business correspondence. Open VS Code, and FluidVox formats your words as clean technical prose. There are six built-in styles — Natural, Polished, Professional, Developer, Concise, and Casual — and you can assign any app on your Mac to the style that fits.

The app detects where your cursor is the moment you start recording. There's zero configuration in the moment — just speak naturally, and the AI handles the rest.

Gets smarter the more you use it

When FluidVox gets a word wrong and you manually correct it, the app notices. It monitors the text field after injection and, if it detects you've made a correction, it learns from it. Over time, FluidVox builds up a set of replacement rules tailored to your voice, your accent, and your vocabulary — all validated by AI before being saved, so only genuine spelling and transcription fixes are kept.

You can also build a personal dictionary for words that matter to your work — product names, colleagues' names, technical terms, acronyms. These get fed directly into the AI so it recognizes them from the start.

50+ languages

FluidVox supports dictation in over 50 languages, from Spanish and Mandarin to Hindi and Arabic. Every non-English transcription automatically gets a full AI cleanup pass — fixing grammar, punctuation, and formatting in the target language — regardless of which style you're using.

Two ways to record

Walkie-talkie mode: Hold the Fn key and speak. Release to transcribe. Ideal for quick messages, search queries, and short replies — anything where you know exactly what you want to say.

Hands-free mode: Press Fn + Space to start, then speak for as long as you need. Press Fn again to stop. Perfect for longer sessions like drafting emails, writing documentation, or journaling.

Private by design

FluidVox only captures audio while you're actively holding the hotkey or in a hands-free session — it never records in the background. Your personal dictionary, replacement rules, and transcription history are stored locally on your Mac.

Free to start, Pro when you need it

FluidVox includes a free tier with 2,000 words per week — enough for casual use, quick messages, and trying things out. When you need unlimited dictation, FluidVox Pro removes the cap entirely. Every new user gets a 14-day free trial of Pro, no credit card required.

Get started

FluidVox lives in your menu bar and stays out of the way until you need it. Setup takes about a minute: download, grant microphone and accessibility permissions, and start talking.
