Best Cotypist Alternatives for Mac (2026)

The best Cotypist alternative for Mac depends on which job you need done. Charm is the top pick for replacing Cotypist's prediction while also correcting spelling and grammar in every Mac app, on Intel as well as Apple Silicon, for a one-time $9.99 with no daily word cap. Harper is the strongest free choice for grammar checking inside a code editor, and LanguageTool leads for writing in more than one language.

Why do people look for a Cotypist alternative?

Cotypist is a well-built Mac app that predicts your next words inline as you type, using a local model. If it runs on your machine and you like it, it is a good product. People look elsewhere for three reasons.

Hardware is the first. Cotypist requires an Apple Silicon Mac on macOS 14 or later, recommends 16GB of memory, and uses roughly 1 to 2.5GB of RAM while active. Intel owners cannot install it at all.

Pricing shape is the second. Cotypist's own pricing page lists the free plan at 100 completed words a day, with unlimited use behind a Plus or Pro subscription and a 30-day Pro trial on install (checked 27 August 2026). On hardware their site is equally direct: Cotypist states that "Cotypist runs entirely on Apple Silicon Macs", which is what rules out every Intel Mac still in daily use.

Scope is the third. Cotypist finishes your words; it is not a spelling or grammar corrector. If you mainly want fewer typos in Slack and cleaner sentences in email, prediction alone does not get you there.

What are the best Cotypist alternatives for Mac?

1. Charm - $9.99 once

Charm is our app, so treat this section as informed rather than neutral. It is a native macOS menu bar app with three features running together: real-time spelling correction, grammar fixing on sentence boundaries, and next-word prediction accepted with Tab. All of it runs on-device.

Against Cotypist, the practical advantages are hardware and pricing: Charm runs on Intel and Apple Silicon Macs on macOS 14 or later, and it is $9.99 once, with no daily word cap and no renewal. One licence covers three Macs. For the feature-by-feature version, see our Charm vs Cotypist comparison.

The honest limitations: Charm is English only, its prediction is word and learned-phrase level rather than the longer sentence completions a dedicated model produces, and in browsers and Electron apps it works through Fix Selection (Option-Command-V) rather than correcting live, because the Chromium accessibility layer is not reliable enough for automatic writes. Cotypist does inline completion in Chrome more aggressively.

Best for: Writers who want prediction and correction in one place, in every Mac app, without a subscription. It is the closest like-for-like swap for Cotypist on an Intel Mac.

Not for: People who want long sentence completions, who write in a language other than English, or who need live correction inside Chrome and Electron apps rather than the Option-Command-V Fix Selection step.

2. Harper - Free, open source

Harper is a free, open-source grammar checker maintained by Automattic. It runs entirely offline, it is written in Rust, and it is fast enough to check as you type without the lag people associate with cloud grammar services. No account, no telemetry, no paid tier.

It suits developers and writers who work inside a small number of tools. Harper ships as integrations rather than a system-wide layer: a browser extension, an Obsidian plugin, and language-server support for editors like VS Code, Neovim and Zed. Inside those, it is excellent.

The limitation is exactly that: the shipping integrations are not system-wide, and Harper does not predict. Leave your editor and type into Mail or Messages and the extensions are not there. Harper's own site now advertises Harper Desktop, a Mac app it describes as covering "every text field, system-wide", but it is early beta and its latest release (v2.8.0, 13 August 2026) ships editor extensions, a browser plugin and a command-line tool with no Mac app among the downloads. As a Cotypist replacement Harper swaps one job for a different one, so treat it as a complement.

Best for: Developers and writers who work inside a handful of editors and want offline grammar checking with no account and no cost.

Not for: Anyone wanting proven system-wide coverage today, or next-word prediction, which Harper does not do. Its system-wide Mac app is still early beta, so outside your editor and browser you are relying on unreleased software.

3. Raycast AI - Free tier, Pro around $8 per month

Raycast AI adds a Fix Spelling and Grammar command to the Raycast launcher, and its Quick Fix behaviour replaces selected text in place rather than making you copy the result back. Because it hangs off a launcher rather than a text field, it works anywhere you can select text, including browsers and Electron apps.

It suits people who already live in Raycast. If you have muscle memory for the hotkey, a grammar command costs nothing new to learn, and you get frontier models for rewriting as well as correcting.

Two honest limitations. It is cloud-based, so your selected text goes to a model provider, which rules it out for confidential material. And it is deliberate rather than ambient: you select, invoke, review. There is no as-you-type prediction and no automatic correction, so it does not replace what Cotypist does.

Best for: People who already live in Raycast and want a grammar command on a hotkey they have muscle memory for.

Not for: Confidential writing, since selected text goes to a model provider, and anyone wanting correction that happens without being invoked.

4. Apple Intelligence Writing Tools - Free with macOS

Apple Intelligence Writing Tools are built into recent macOS releases and reach every text field on the system. You select text, invoke Writing Tools, and can proofread, rewrite or change the tone. Nothing to install, nothing to pay, and Apple keeps most of it on-device.

It suits people who already have a compatible Apple Silicon Mac and want a free baseline for tidying up longer writing before sending it.

The limitations matter if you are coming from Cotypist. Writing Tools require Apple Silicon, so Intel owners are excluded here too, and there is no inline as-you-type correction or next-word prediction: it is select-and-invoke, so it never helps you mid-sentence. It also tends to rewrite rather than correct.

Best for: Apple Silicon owners on a recent macOS who want a free baseline for tidying longer passages after writing them.

Not for: Intel Mac owners, who are excluded outright, and anyone who wants correction as they type rather than a rewrite they trigger on a selection.

5. macOS text replacement and spell check - Free

macOS has shipped spelling correction and text replacement for years, in System Settings under Keyboard. It works in every app, costs nothing, needs no permissions and uses no extra memory. Text replacement is useful for snippets you type constantly, such as an address or a support reply.

It suits anyone who wants a zero-cost floor before paying for anything. Set up a dozen replacements and you will recover a surprising amount of typing.

The limitation is that it is a dictionary, not a model. Text replacement fires only on exact triggers you defined, autocorrect is limited to single-word spelling substitutions, and there is no grammar checking or contextual prediction. Our guide to the best autocorrect for Mac covers where the built-in behaviour breaks down.

Best for: Anyone who wants a zero-cost floor before paying for anything, especially for a dozen phrases typed daily.

Not for: Catching typos you did not predict in advance. Text replacement fires only on exact triggers you defined yourself.

6. LanguageTool - Free tier plus premium

LanguageTool is the strongest option for multilingual writers, covering more than 30 languages with grammar and style checking. That breadth is the reason to choose it: Cotypist, Charm and Harper are all far narrower. It has a free tier with a per-check character limit and a premium subscription for the full rule set.

It suits people who write in two or more languages daily, particularly in browser-based tools like Google Docs, Gmail and web CMS platforms, where its extension does its best work.

The limitation is that it is cloud-first: your text goes to LanguageTool's servers unless you self-host the open-source server, which is realistic for developers and not for most people. Its Mac app is closer to a checking window than a system-wide layer, and it does no prediction.

Best for: People writing in two or more languages every day, particularly in Google Docs, Gmail and other browser tools.

Not for: Anyone who cannot send text off the machine, unless you self-host the open-source server yourself.

7. Wysp and WunderType - Newer, subscription-free contenders

Wysp and WunderType are recent Mac writing tools positioning themselves against Cotypist on the same argument: on-device processing without a recurring subscription. Both are worth a look if the pricing model matters to you.

Be clear-eyed about the trade-off. Both are young, with shorter track records and less public evidence about how they behave in the awkward parts of the Mac, which is where writing tools actually get tested: Electron apps, web text areas and code editors. Check current requirements and trial terms yourself, and test on the apps you really use.

Best for: Early adopters who want on-device prediction without a subscription and are comfortable backing a young app.

Not for: Anyone who needs a track record. Both are new, with less public evidence about how they behave over months of use.

How do the alternatives compare?

Which alternative should you choose?

Start with the constraint that rules options out. On an Intel Mac, Cotypist and Apple Intelligence are off the table entirely; Charm, Harper, LanguageTool and the macOS built-ins all still work.

If you want the same ambient feel but with correction as well as prediction, Charm is the closest match. If you only want grammar and you live in an editor or browser, Harper is free, offline and hard to beat. If you write in several languages, LanguageTool is the only serious answer. If you want zero new software, try macOS text replacement first.

Frequently asked questions

Does Cotypist work on Intel Macs?

No. Cotypist requires an Apple Silicon Mac running macOS 14 or later, and it recommends 16GB of memory. Intel Mac owners cannot run it at all. Charm runs on both Intel and Apple Silicon Macs on macOS 14 or later, which makes it the most direct replacement for Intel users.

Is there a Cotypist alternative without a subscription?

Yes. Charm is a single $9.99 one-time purchase with no daily word cap and no renewal. Harper and the macOS built-in tools are free. Wysp and WunderType also position themselves as subscription-free, though both are newer and less proven than the established options.

What is the best free Cotypist alternative for Mac?

Harper is the best free option if you mainly want grammar checking, since it is open source, offline and fast. If you want something already installed, Apple Intelligence Writing Tools and the macOS spelling and text replacement features cost nothing, but none of these three offer inline next-word prediction the way Cotypist does.

Does Charm predict whole sentences like Cotypist?

No. Charm predicts the next word and completes learned phrases you type often, accepted with Tab. It does not generate long multi-word sentence completions the way a dedicated prediction model does. If sentence-length completion is the single feature you care about, Cotypist does that job more aggressively than Charm.

Do these tools work in Chrome and Electron apps?

Coverage varies. Charm corrects automatically in native Mac apps and uses Fix Selection (Option-Command-V) in browsers and Electron apps, where the accessibility layer is less reliable. Raycast AI works anywhere you can select text. Harper works through editor and browser integrations rather than system-wide.
