Slack Voice Dictation

Stop switching context. Just speak and send.

Hold a key. Speak your thoughts. Keep your flow.

Write where you work

Aqua is a system-wide dictation layer for Mac, Windows, iPhone, and Android. On a Mac or Windows PC, hold a key anywhere in Slack and speak, and your words land in the message box formatted and ready to send: a channel update, a thread reply, a DM, a canvas, or a search.

How to dictate in Slack with Aqua

Start in a channel, thread, or direct-message box. Aqua puts your words into the field you have focused.

Download Aqua for Mac or Windows and grant microphone access. On macOS you will also be asked for Accessibility access, which is what lets Aqua type into the focused field.
Pick your hold-to-talk key in Aqua's settings.
Click into any Slack message box: a channel, a thread, a DM, or a canvas.
Hold your key, say your update, and release. The text appears formatted and ready to send.
Add teammate names, channel names, project codenames, and your team's internal shorthand to your custom dictionary.

Tips for dictating in Slack

Say the structure out loud. "Three updates, one blocker" gives Aqua something to format against, and gives your channel something skimmable.
Aqua reads the context on your screen, so it pitches a channel update tighter than a DM without you switching any settings.
Put people's names in your custom dictionary. Nothing undermines a fast update like a mangled colleague.
For a long thread reply, speak the whole thing in one pass and edit after. Stopping to fix a word mid-thought costs more than the fix is worth.

Does Slack have built-in voice dictation?

No, and the microphone button is the reason people think otherwise. That button records an audio clip, a voice memo your teammates have to play. Slack can attach a transcript to the clip afterwards, but there is no composer that types your speech into the message box. On mobile you can tap the mic on your phone keyboard, which is your operating system doing the work, not Slack. On desktop there is nothing. Aqua fills that gap: you hold a key, speak, and text appears in the box, so what your team reads is a message rather than a two-minute recording they have to listen to.

For coding prompting with voice nothing beats @aquavoice All the other transcription apps don't work well with code like tailwind class names

@chiggyAI

just tried out @aquavoice and by far the most accurate voice to text tool i've used!!

@TheNathanRuff

Been using @aquavoice for a few months. Unbelievably better than the other companies that do this

@jamesfong

3 products that have broken into my forever home. And that's not an easy feat for me: @circlebackai, @aquavoice, and @superset_sh

@tzmartin

tbh @aquavoice is a vibe coder's delight.. lowest latency, highest quality STT I've used so far

@juanbuis

this is why @aquavoice is better than all other AI transcription apps it actually writes like you talk

@heyvyner

Mapping @aquavoice to this button on my mouse is a whole different level of productivity.

@nozmen

Aqua Voice: I barely type long prompts now, just talk. Saved ~5 hrs typing in 2 weeks. Much more accurate than macOS dictation.

@gkossakowski

Aqua is a true power tool: quick, reliable and understands your context - they were early at appreciating the value of context engineering.

@jackson_felty

@aquavoice is a prime example of how much better a product can be when the team focuses on making one simple use case incredible

@ArtemR

Aqua Voice @aquavoice is the voice-based text editor I think all of us have always wanted, but no company has been able to deliver so far. The demo is extremely impressive

@jaymehoffman

@aquavoice has saved me over 2 days of typing

@curious_vii

Claude Code agents (new CLI view) + Ghostty + @aquavoice is actual calm computing

Does Aqua work in threads, DMs, and canvases?

Yes. Aqua types into whatever field has focus, so the same key works in channels, threads, DMs, canvases, and the search box.

Will it match my tone in a channel versus a DM?

Aqua reads the context on your screen and adjusts, so channel updates come out concise and DMs stay conversational.

Does it work on Windows?

Yes. Aqua runs on Mac, Windows, iPhone, and Android.

How much does it cost?

Free includes 2,000 words. With annual billing, Pro is $10 per month, Max is $19 per month, and Business is $19 per seat per month with a minimum of 2 seats.
