TL;DR: Messaging is the one place where dictation apps visibly stop half way, because a message is not finished until it is sent. Infina is the simplest app in this roundup for saying the whole thing: "open Slack", "type" and your message, "send it". It is a flat $8.25 a month, billed annually at $99. Wispr Flow wins if you also message from a phone, Apple's free tools are better than most people realize, and we say exactly where each one beats us.
Messaging has two requirements, and most apps meet one
It has to read like a person wrote it. A Slack reply full of "um" and missing punctuation costs you more credibility than the ten seconds it saved. Even more than when prompting an AI agent, here the cleanup matters.
It has to actually go. Every message ends with a deliberate Return, and across Gmail, Slack, iMessage and WhatsApp that is dozens of keypresses a day whose only purpose is to complete an action you already finished speaking.
| App | Dictates | Polishes | Sends by voice | Switches to the app by voice | Price |
|---|---|---|---|---|---|
| Infina | Yes, say "type" | Yes, included, on your Mac | Yes, "send it" or "enter" | Yes, "open Slack" | $8.25/month, billed annually at $99 |
| Wispr Flow | Yes, hold a key | Yes, included | No | No | $15/mo ($12/mo annual) |
| Superwhisper | Yes, hold a key | Yes, per-context modes | No | No | $84.99/yr; $249.99 lifetime |
| Apple Dictation | Yes, press the mic key | No | No | No | Free |
| macOS Voice Control | Yes | No | Yes, "press return" | Yes | Free |
| VoiceInk | Yes, hold a key | No | No | No | $25 to $49 once |
1. Infina: the simplest way to finish the message
Three spoken triggers and no fourth. "Open Slack" puts you in Slack. "Type" plus your sentence writes the message. "Send it", or a plain "enter", sends it. Then "open Gmail" and do the next one.
Nothing is held down at any point, which is what makes this different from every hotkey app here. You can clear a morning of Slack threads while making coffee, walking around, or with a baby on one arm, and the messages actually go out rather than sitting unsent in six different composers.
The text comes out clean, which matters most when the reader is a person. On a Mac, Tami 1, Infina's own cleanup model, removes the "um"s, "uh"s and stutters and fixes punctuation and capitals, while keeping your words and the names you said. It is on by default, included on the Free plan too, and your message is not sent to a server for cleanup.
Infina Unlimited is a flat $8.25 a month, billed annually at $99 (at the time of writing), unlimited words and unlimited voice commands, a Free plan of 2,000 free words with no card, a 7-day refund, and nothing else to buy. Transcription runs on your Mac by default, which matters more in messaging than people think: your messages are about clients, salaries, and colleagues.
Pick it if: you clear a lot of messages a day and want them written and sent by voice. Skip it if: you message mostly from a phone. Walkthroughs: voice typing for Slack, voice typing for Gmail.
2. Wispr Flow: best if the phone is where you message
Wispr Flow covers Mac, Windows, iPhone, and Android with one subscription and 100+ languages, and its rewrite layer is included: filler stripped, punctuation fixed, tone matched, without you asking, all done on its servers.
For messaging, that included rewrite is its strongest argument, and if you reply to Slack from a phone half the time it covers both on one subscription. At $15/month, or $12/month billed annually, it costs $144 to $180 a year against $99, it is cloud-only, and it stops before the send.
Pick it if: phone plus desktop, or many languages. Skip it if: you want the send handled or the audio kept local. See Wispr Flow vs Infina.
3. Superwhisper: best per-context polish on the Mac
Superwhisper's output modes are the underrated feature for messaging: one mode for email that writes in full sentences, another for Slack that keeps things short. It runs locally, costs $84.99/year or $249.99 lifetime, and has a free tier.
It is hotkey-driven and stops at inserting text, so every message still ends with your hand on Return.
Pick it if: you want different tone in different apps, locally. Skip it if: the send is the part you want gone.
4. macOS Voice Control: free, and it can send
This is the answer most people searching for free messaging dictation never find. Voice Control is a separate feature from Apple Dictation, it lives in Accessibility settings, and it controls the whole Mac: it can click into a message field, dictate, and press Return.
It is free and on-device. What it asks in return is that you operate its command grammar, and holding a fast messaging rhythm inside that grammar takes real concentration. But it can complete the action, and it costs nothing.
Pick it if: free matters more than fluency. Skip it if: you want three words instead of a grammar.
5. Apple Dictation: the free baseline
Press the mic key, talk, and the words land in any message field on the Mac. Free, installed, fine for a sentence. Punctuation and names are where it slips, and in messaging those are exactly the things a reader notices. No send.
Pick it if: you dictate the occasional reply. Skip it if: messaging is a large part of your day.
6. VoiceInk: cheapest local option
Open source, local Whisper models, $25 to $49 once. It puts text in a message box privately and cheaply, with no polish layer and no send.
Pick it if: budget and privacy, nothing more. Skip it if: you want either half of what messaging actually needs.
When Infina is not the answer
- You message mostly from a phone. Wispr Flow or Superwhisper. Infina is Mac and Windows only.
- You message in a language other than English and want it on the Free plan. On your computer Infina transcribes English; 100+ languages come with optional cloud transcription on Infina Unlimited. Wispr Flow and Superwhisper also cover other languages.
- You want free. macOS Voice Control can dictate and press Return at no cost.
- You cannot use a keyboard at all. Voice Control or Talon, which also click and scroll. Infina does not.
FAQ
Can I send a Slack message entirely by voice on a Mac? Yes. With Infina: "open Slack", then "type" and your message, then "send it" or "enter". Nothing is held or pressed. macOS Voice Control can also do it for free using its own commands. Wispr Flow, Superwhisper, Apple Dictation, and VoiceInk all stop before the send.
What is the best dictation app for writing emails? If you want clean text written and sent hands-free, Infina, which cleans up your email on your Mac with Infina's Tami 1 instead of sending it to a server. If you also email from a phone, Wispr Flow's included rewrite layer covers both, in the cloud. For occasional emails, Apple Dictation is free and already there.
Is dictated text good enough to send to colleagues? Uncleaned dictation usually is not, because filler words and missing punctuation read as careless. Use a tool with a cleanup layer for messages humans read. On a Mac, Infina's Tami 1 does that on your computer by default: filler and stutters removed, punctuation and capitals fixed, your words kept.
Does dictating messages send my words to a server? With Wispr Flow, yes, it is cloud-only. Infina, Superwhisper, VoiceInk and Apple's tools transcribe on your Mac by default. Given that work messages contain client names and salary numbers, this is worth deciding deliberately.
Can I dictate into WhatsApp and iMessage on a Mac? Yes, any of these apps type into both, since they are ordinary text fields. The difference is whether the message sends: Infina and macOS Voice Control can press Return, the rest cannot. See dictate and send messages on Mac.
The bottom line
Messaging needs two things, clean text and a send. Infina covers both: the send by voice, and the cleanup on your Mac with Infina's Tami 1, at one price with nothing else to buy. Wispr Flow covers the cleanup and the phone in the cloud, and leaves the send to you. macOS Voice Control covers the send for free and asks for patience. Superwhisper has the most per-context modes, VoiceInk is the cheapest, Apple Dictation the free baseline.
App by app: Slack, Gmail, iMessage, WhatsApp.
The short answer, by what you are trying to do
If you want to skip the detail above, find your sentence in this table and buy that one.
The tools this page covers (Wispr Flow, Superwhisper, VoiceInk, Talon, Apple Dictation) are at the top. The rest of the field follows, because the right answer is sometimes none of the above.
| Tool | Price | Keyboard needed | Pick it if |
|---|---|---|---|
| Infina | $8.25 a month, billed annually at $99, unlimited words and unlimited commands | No. Speak "type", speak the prompt, say "send it" or "enter". | you want to prompt AI tools without touching the keyboard. Say "type" and the words go in, "send it" and the prompt goes, "open Cursor" and you are in the next agent. It is the only one of these that finishes the whole loop by voice in the tools developers prompt in all day. |
| Wispr Flow | $15 a month, or $144 a year billed annually | Yes. A key to start dictating, Enter to send. | you need dictation on an iPhone or an Android phone as well as a laptop, or you write in one of 100+ languages. Those are the two things Infina does not ship. |
| Superwhisper | $8.49 a month, $84.99 a year, or $249.99 once | Yes. A key to start dictating, Enter to send. | you want to pick and swap the speech model yourself, and dictation into a text box is the whole job. It stops where the text box ends: there is no spoken send, and no spoken app switch. |
| VoiceInk | $25 to $49, paid once | Yes. A key to start dictating, Enter to send. | you want plain local dictation at the smallest possible price and you never need your voice to control the machine. |
| Talon | free | No, once you have learned its command language. | you want to drive the entire computer by voice, cursor and clicks included, and you are willing to learn a command language to get there. Talon is the serious hands-free tool on this list. Infina goes after the same freedom with three ordinary English words instead of a syntax to learn. |
| Apple Dictation | free, built in | Yes. A key to start dictating, Enter to send. | you dictate a sentence here and there and do not want to install anything. |
| MacWhisper | 65 euros, paid once | Yes. A key to start dictating, Enter to send. | the job is transcribing recorded audio files rather than talking to your computer while you work. |
The part that is actually different: zero keypresses
The mainstream dictation apps (Wispr Flow, Superwhisper, MacWhisper, VoiceInk, Apple Dictation) are all push-to-talk: you hold or press a key to start talking, and you press Enter to send. That is two physical acts on every single prompt. A hundred prompts in a day is two hundred keypresses that exist only to start and stop the tool. Infina removes both of them. Nothing is held, nothing is pressed, and the same loop runs on three spoken words.
There are three triggers and there is no fourth. "type" types, "send it" sends, "open" opens and switches apps. The send trigger answers to either wording, "send it" or a plain "enter", whichever you find yourself saying. That is the entire vocabulary: no command language, no grammar, no custom scripts to write, nothing to memorize beyond those three words.
When Infina is not the answer. If you need dictation on an iPhone, an iPad, an Android phone or Linux, Infina is a Mac and Windows desktop app and there is no phone version. Wispr Flow covers phones.
Everywhere else, the difference is the loop. Every other tool in that table types words into a box and stops, leaving your hands to press Enter and pick the next window. Infina finishes it: say "type" and your sentence, say "send it" (or just "enter"), say "open Cursor", and keep going without a key.
Quick answers
What are the trigger words in Infina? Three. Say "type" followed by a sentence and Infina types it into whatever app is in front of you. Say "send it", or just "enter", and it presses Enter, so the prompt actually goes. Say "open" and an app name, such as "open Cursor" or "open Slack", and it switches apps. That is the whole loop, and none of it needs a hotkey or a key held down.
Can I use Claude Code or Codex without touching the keyboard? Yes, with Infina running in hands-free mode. Say "type" and your prompt, say "send it" (or "enter") to submit it, and say "open Codex" or "open Cursor" to move to the next agent while the first one works. Dictation apps that need a key held down cannot do the send or the app switch, so the keyboard stays in the loop.
Is there a dictation app that does not need a hotkey or push-to-talk? Infina, in hands-free mode. The mainstream dictation apps (Wispr Flow, Superwhisper, MacWhisper, VoiceInk, Apple Dictation) are all push-to-talk: you hold or press a key to start talking, then press Enter to send, which is two physical acts on every prompt. Infina removes both. Say "type" and your sentence, say "send it" or "enter", say "open Cursor". Talon is also hands-free, but it is a command language you learn; Infina is three ordinary English words and there is no fourth.
Is Wispr Flow or Infina better? Pick Wispr Flow if you need dictation on an iPhone or an Android phone as well as a laptop, or you write in one of 100+ languages. Those are the two things Infina does not ship. Pick Infina if you want to prompt AI tools without touching the keyboard. Say "type" and the words go in, "send it" and the prompt goes, "open Cursor" and you are in the next agent. It is the only one of these that finishes the whole loop by voice in the tools developers prompt in all day. Wispr Flow costs $15 a month, or $144 a year billed annually; Infina is $8.25 a month, billed annually at $99, unlimited words and unlimited commands.
