Cotypist Free Alternative: Try GhostPen, a Local AI Writing App for Mac

If you are looking for a Cotypist free alternative, you are probably in one of these situations:

• you like the idea of AI autocomplete while writing
• you do not want another subscription
• you prefer local AI tools that run on your own device
• you want something simpler and less invasive
• you want to keep your writing private

That is exactly why I built GhostPen.

GhostPen is a local AI-powered writing app for Mac. It helps you write faster by suggesting the next few words while you type, similar to GitHub Copilot, but for normal writing instead of code.

You write. GhostPen suggests. You press Tab. You keep going.

No prompts. No chatbot. No cloud AI by default.

Your writing stays on your device.

Why people are looking for Cotypist alternatives

Cotypist introduced a very useful idea: AI autocomplete that works while you write. For many people, this feels much better than opening ChatGPT, explaining what you want, waiting for a response, copying the answer, editing it, and pasting it back into another app.

The problem is that many users do not want to pay a recurring subscription for a local AI tool running on their own Mac.

I understand both sides. Developers should be paid for good software. Building a polished macOS app takes time, care, and maintenance.

But I also understand why many users feel differently about subscriptions when the app runs locally and the compute happens on their own hardware.

For this kind of tool, many people would rather have:

• a free beta
• a one-time payment
• paid major upgrades
• or a very simple, fair pricing model

That is one of the reasons GhostPen exists.

What is GhostPen?

GhostPen is a focused writing app with local AI autocomplete built directly into the editor.

Instead of trying to add suggestions to every app on your Mac immediately, GhostPen starts with a simpler idea:

What if you had a clean writing editor where local AI helps you finish your thoughts?

For example, you type:

Hey Marco, thanks for the update. I’ll take a look and send you an email lat…

GhostPen suggests:

…er this evening.

Then you press Tab and keep writing.

The goal is not to let AI write for you.

The goal is to help you stay in flow.

GhostPen vs Cotypist

Cotypist and GhostPen are similar in spirit, but different in approach.

Cotypist focuses on system-wide autocomplete. It tries to provide suggestions across many apps on your Mac.

GhostPen currently focuses on autocomplete inside its own editor.

That means GhostPen is not a full Cotypist replacement yet if what you want is autocomplete in every text field across macOS.

But the editor-first approach has some advantages:

• it is simpler
• it is less invasive
• it avoids buggy overlays in random apps
• it does not need to run everywhere all the time
• it can be more focused on the core writing experience
• you only use AI suggestions when you actually want them

For many users, that is enough.

You open GhostPen, write your text, accept suggestions, then paste the final result into Gmail, Outlook, Google Docs, Reddit, Notes, Slack, or wherever you need it.

Why not just use ChatGPT?

ChatGPT is powerful, but it often breaks your writing flow.

The usual workflow looks like this:

1. stop writing 2. open ChatGPT 3. explain the context 4. wait 5. copy the result 6. paste it back 7. edit it until it sounds like you

GhostPen is different.

It does not ask you to prompt an assistant. It simply helps while you are already writing.

The workflow is:

1. start writing 2. see a short suggestion 3. press Tab 4. keep writing

That is the whole product.

Local AI autocomplete for Mac

GhostPen uses local AI models to generate autocomplete suggestions on your device.

That matters because your writing can be personal, sensitive, or unfinished.

You might be writing:

• emails
• private notes
• journal entries
• product ideas
• school work
• client messages
• blog posts
• Reddit comments
• personal thoughts

You should not have to send all of that to an external AI server just to get help finishing a sentence.

GhostPen is built around a local-first approach.

After the model is available on your device, GhostPen can help you write without sending your drafts to OpenAI, Anthropic, or external servers.

Is GhostPen free?

GhostPen is currently free during beta.

I do not plan to make it a subscription app.

The long-term pricing may change as the project grows, but the goal is to keep it fair and aligned with how people think about local-first tools.

I want GhostPen to feel like useful software you can own and trust, not another monthly AI bill.

What GhostPen currently supports

GhostPen is still early, but it already supports:

• local autocomplete suggestions
• short inline completions
• Tab to accept
• spell checking
• grammar-aware suggestions
• lightweight local models like Qwen and Gemma
• an experimental rewrite feature similar to Apple Writing Tools

The rewrite feature is still experimental and disabled by default, but you can enable it in settings if you want to try it.

What GhostPen does not do yet

GhostPen is an early beta, so it is important to be clear.

At the moment, GhostPen does not provide system-wide autocomplete across every Mac app.

It only provides suggestions inside its own editor.

I may explore system-wide suggestions in the future, but for now I am focusing on making the core writing experience feel good first.

That means:

• faster suggestions
• better completions
• cleaner writing flow
• better local model support
• a simple, reliable editor

I would rather make one focused experience work well than overpromise support for every app immediately.

Who is GhostPen for?

GhostPen might be useful if you:

• liked Cotypist but do not want a subscription
• want a local AI writing app for Mac
• prefer writing in a clean editor
• care about privacy
• want short autocomplete suggestions instead of long AI-generated paragraphs
• write emails, notes, posts, or articles often
• want AI help without opening ChatGPT every time

GhostPen is probably not for you yet if you need:

• perfect Cotypist-level polish
• system-wide autocomplete everywhere
• enterprise features
• heavy document management
• a full AI chat app

It is intentionally focused.

The best Cotypist alternative depends on what you want

If you want system-wide autocomplete everywhere, Cotypist is still one of the most polished tools in this category.

If you want a free and open-source system-wide alternative, Cotabby may be worth watching.

If you want a simpler local AI writing app with a focused editor, no cloud AI by default, and no subscription planned, GhostPen may be a good fit.

The difference is simple:

• Cotypist: system-wide autocomplete
• Cotabby: open-source system-wide alternative
• GhostPen: focused local AI writing editor

GhostPen is not trying to clone Cotypist completely.

It is trying to solve the same writing-flow problem in a simpler way.

I would genuinely love feedback, especially from people who have used Cotypist, Cotabby, GitHub Copilot, ChatGPT, or other AI writing tools.

GhostPen is still early, but the goal is clear:

Help you keep writing, without sending your words to the cloud or forcing you into another subscription.
