TL;DR: On an 8GB MacBook the real question is not accuracy, it is what else you can keep open. Infina runs a small on-device model and adds the hands-free loop, so you talk to Cursor and Claude Code without a browser tab full of anything. Wispr Flow is genuinely the lightest option because it does the work in the cloud. Superwhisper and MacWhisper let you pick a small model. Below, where each one hurts and where it does not.
One thing to hold in mind while you read the rankings below. Infina runs on three spoken triggers and there is no fourth. Say "type" and a sentence and it lands as typed text in whatever app is in front of you. Say "send it", or just "enter", and it presses Enter so the prompt actually goes. Say "open Cursor" or "open Slack" and your computer switches apps for you.
Nothing is held down and nothing is pressed. There is no push-to-talk key to find and no Enter key to reach for two hundred times a day, which is the part every other tool in this category leaves to your hands. Wispr Flow, Superwhisper and the rest all stop at inserting text, which leaves the two keypresses around every prompt exactly where they were.
Why 8GB changes the ranking
A local speech model is a file that has to sit in memory while you talk. A small English-only model is a few hundred megabytes. A large multilingual one can be several gigabytes. On a 16GB or 32GB Mac nobody notices. On an 8GB MacBook Air with Chrome, Slack, and an editor already open, the difference between a small model and a large one is the difference between a normal machine and a machine that swaps.
So the ranking here inverts the usual one. The tools that send your audio to a server are the lightest, because they hold no model at all. The tools that run locally are heavier but private. Pick your side deliberately.
We are not going to publish invented megabyte figures for each app. Vendors do not publish them consistently, memory use depends entirely on which model you load, and a number we cannot verify is worse than no number. What follows is the structural read, which is the part that actually decides this.
| App | Where transcription runs | Model size you control | Hands-free | Price |
|---|---|---|---|---|
| Infina | On your Mac (small model by default) | Not exposed, tuned small | Yes, three triggers | $99/year |
| Wispr Flow | Cloud | None held locally | No | $15/mo ($12/mo annual) |
| Superwhisper | On your Mac | Yes, tiny to large | No | $84.99/yr; $249.99 lifetime |
| VoiceInk | On your Mac | Yes, tiny to large | No | $25 to $49 once |
| MacWhisper | On your Mac | Yes, tiny to large | No | Free tier; Pro €65 once |
| Apple Dictation | On your Mac, by the OS | No | No | Free |
1. Infina: small model, and the loop that saves you the reopening
Infina runs a compact speech model on your Mac, chosen to be light rather than maximal, and you do not have to pick it. The point of the product is not the model, it is what happens around it: "open Cursor", "type" plus your sentence, "send it" or "enter". Three words, nothing held down, no push-to-talk key, no reaching for Return.
There is a specific 8GB argument here that nobody else makes. When your machine is tight on memory, the thing you do constantly is close and reopen apps, and every reopen is a fresh round of clicking into the right window and the right text field. The "open" trigger removes that: you say the app name and you are in it, already able to type by voice. On a machine where you are app-juggling all day, that is the feature.
Hands-free does ask for headroom. We are honest about that: if your Mac is already at the edge with 40 Chrome tabs, run Infina in push-to-talk mode, which is also included, and the always-listening layer stays off.
$99/year flat at the time of writing, unlimited words and commands, 2,000-word trial with no card, 7-day refund. Also see offline dictation on Mac and on-device dictation.
Pick it if: 8GB and you want the loop, not just the words. Skip it if: your machine is already swapping constantly, in which case a cloud tool is genuinely lighter.
2. Wispr Flow: the lightest, because it is not local
This is the honest top pick on memory alone. Wispr Flow sends audio to a server, so there is no model in your RAM at all, just a small client. On a loaded 8GB Air it will be the least disruptive thing in this list.
You pay for that in two currencies: your audio leaves the machine, and it costs $15/month, or $12/month billed annually, which is $144 to $180 a year against Infina's $99. It also needs a connection, so on a plane or a bad hotel network you have nothing. It stops at inserting text, with no way to send.
Pick it if: memory pressure is your daily reality and cloud is fine. Skip it if: privacy or offline matters. See Wispr Flow vs Infina.
3. Superwhisper: local, with the size dial in your hands
Superwhisper is the best choice for someone who wants local transcription and wants to make the memory tradeoff themselves. It lets you pick the model, and on 8GB you should pick a small one and stop there. The large models are the ones that will hurt you.
Free tier, $84.99/year, or $249.99 lifetime, which undercuts Infina on price. It is hotkey-driven, so you hold a key and you press Return yourself.
Pick it if: you want to tune the model to your machine. Skip it if: you would rather not think about model sizes at all.
4. VoiceInk: cheapest local, same dial
Open source, local Whisper models, $25 for one Mac up to $49 for three, with a 14-day refund. Same advice as Superwhisper: load a small model and it behaves well on 8GB; load a large one and it will not.
The cheapest way to get private local dictation on a memory-constrained Mac. No polish layer, no commands, no send.
Pick it if: budget first, privacy second, nothing else. Skip it if: you want a loop rather than a transcriber.
5. MacWhisper: best for files, not for all-day typing
MacWhisper's strength is transcribing recordings, meetings, and audio files, and it is very good at it. For that job you load a bigger model and accept the memory cost for a few minutes, which is a much easier deal on 8GB than holding a model all day.
Free tier with smaller models, Pro at €65 once. You will see €59 in SEO roundups; that is out of date. Its live dictation exists but is not the reason people buy it.
Pick it if: you transcribe recordings more than you type. Skip it if: you want dictation as your daily input. See MacWhisper vs Infina.
6. Apple Dictation: zero extra memory, because it is already running
The OS handles it, there is no third-party app resident, and it is free. On a tight machine that is a real argument. What you get is basic: press the mic key, talk, punctuation and proper nouns are hit and miss, and there is no send and no commands.
Pick it if: the machine is truly at its limit and you dictate occasionally. Skip it if: you dictate for hours.
When Infina is not the answer
- Your Mac is constantly swapping. Wispr Flow holds no model and will feel lighter.
- You want to choose the model yourself. Superwhisper and VoiceInk expose that; Infina does not.
- You mostly transcribe recordings. MacWhisper, every time.
- You want to spend nothing. Apple Dictation adds no memory footprint at all.
- You need 100+ languages. Wispr Flow or Superwhisper.
FAQ
Can I run a local dictation app on an 8GB MacBook Air? Yes, as long as you use a small model. Small English-only models run comfortably on 8GB. The problems people report almost always come from loading a large multilingual model on a machine that cannot spare the memory. Infina uses a compact model by default; Superwhisper, VoiceInk, and MacWhisper let you choose, so choose small.
Is a cloud dictation app lighter than a local one? Yes. A cloud tool like Wispr Flow holds no speech model in memory, so it is the lightest option here by a clear margin. The tradeoff is that your audio leaves your machine and you need a connection.
Does hands-free dictation use more memory than push-to-talk? It keeps a listener running rather than starting one when you press a key, so yes, somewhat. On a machine under heavy memory pressure, Infina's push-to-talk mode is included and turns that layer off.
Which dictation app is best for an M1 MacBook Air? The M1 Air is fast enough for any of these; memory is the constraint, not the chip. If you have 16GB, take Infina or Superwhisper with any model you like. If you have 8GB, keep the model small, or use Wispr Flow and keep nothing local.
Does dictation drain more battery on a small MacBook? Local transcription uses the CPU and Neural Engine, so it costs more battery than sending audio to a server, which costs network instead. Neither is dramatic for normal use. If you are watching every percent on a long flight, note that the cloud option will not work offline at all.
The bottom line
On 8GB the ranking is an honest tradeoff, not a winner. Wispr Flow is the lightest because it is not local. Infina is the best local option that also removes the app-switching and the Return key, which on a memory-tight machine you do more of than anyone else. Superwhisper and VoiceInk hand you the dial. MacWhisper is for files. Apple Dictation costs nothing at all.

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, MacWhisper, VoiceInk, 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 | $99 a year, 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. |
| 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. |
| 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. |
| 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. |
| 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. |
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 write in a language other than English, the base product is English only, and Wispr Flow ships 100+ languages.
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.
