Yes. Core editor features (intuitive math input, build, SyncTeX, PDF preview) are completely free. AI writing assistant Axiom and equation OCR are optional paid features. The Basic plan at $12/month includes AI writing and OCR, and the Pro plan at $25/month provides full access to all features.

Can I use my existing TeX distribution (TeX Live, etc.) with TeX64?

Yes. TeX64 works with your existing TeX distribution (TeX Live, MacTeX, BasicTeX) without any proprietary formats or lock-in. You can open and build your existing LaTeX projects as-is.

What is Axiom, the AI writing assistant in TeX64?

Axiom is the AI writing assistant built into TeX64. Describe your intent in natural language — "write the definition of a Fourier transform" or "complete this proof" — and Axiom instantly drafts the LaTeX code. The suggest → review diff → apply → undo workflow keeps you in full control of the AI output.

What is intuitive math input in TeX64?

TeX64's intuitive math input lets you pick symbols (fractions, integrals, matrices, vectors, etc.) from a visual palette and preview equations in real time as you build them. No need to memorize LaTeX syntax. Dramatically faster than traditional LaTeX input for beginners and experts alike.

Can TeX64 convert equations from images to LaTeX?

Yes. TeX64's equation OCR automatically converts photos of handwritten notes, PDF equations, and textbook screenshots into editable LaTeX code. Just take a screenshot to start the conversion, then edit and build the result directly in the editor.

Does TeX64 work offline?

Yes. TeX64 is a local-first native macOS app. The editor, build system, PDF preview, and SyncTeX all work completely offline. Your data stays on your Mac. Only AI writing assistant Axiom and equation OCR require an internet connection.

Is TeX64 an alternative to Overleaf?

TeX64 takes a local-first approach with offline operation and easy Git integration, plus unique features like AI writing assistant Axiom, intuitive math input, and equation OCR that Overleaf doesn't offer. Ideal for those who prioritize speed, privacy, and Git workflows. Overleaf remains the better choice if you need real-time collaboration.

What are the system requirements for TeX64?

TeX64 runs on macOS 12 (Monterey) or later, with native support for both Apple Silicon (M1/M2/M3/M4) and Intel. A TeX distribution (TeX Live, MacTeX, or BasicTeX) is required separately. AI features and OCR require an internet connection, but core features work fully offline.

What is the best LaTeX editor for macOS?

TeX64 is the most advanced LaTeX editor for macOS. It offers AI-powered LaTeX generation from natural language with Axiom, fast equation building with intuitive math input, and automatic conversion from notes and PDFs with equation OCR — all at native app speed. Other options include TeXShop (free, simple), Texifier (live preview), VS Code + LaTeX Workshop (extensibility), and Overleaf (collaboration), but TeX64 leads in AI integration and math input innovation.

Frequently Asked Questions

Common questions about TeX64, answered.

Before you start

Is it really free? Will I be charged later?

Yes, it is genuinely free. The editor, build, SyncTeX, PDF preview, and intuitive math input are all included in the free plan with no credit card required. Only AI features (Axiom and OCR) are paid, and you will never be charged unless you explicitly upgrade.

Will TeX64 break my existing TeX setup?

No. TeX64 uses your existing TeX distribution (MacTeX, BasicTeX, TeX Live) as-is, with no proprietary format or lock-in. Your existing .tex files work directly. Uninstalling TeX64 leaves your TeX setup and documents completely untouched.

Can beginners use TeX64?

Yes. The intuitive math input lets you build equations visually from a palette without memorizing LaTeX syntax. You can also use Axiom to generate LaTeX from natural language descriptions. And experienced users can write code directly just as comfortably.

Data & privacy

Where is my paper data stored?

All files are stored locally on your Mac. Nothing is uploaded to TeX64 servers. When you use AI features, input text is sent to the server for processing only, and it is never used for AI training.

Can I use it offline?

Yes. The editor, build, SyncTeX, PDF preview, and intuitive math input all work fully offline. Only AI features (Axiom and OCR) need an internet connection.

Pricing & subscription

What happens if I cancel my paid plan?

You keep access until the end of the current billing period. After that, you revert to the Free plan and continue using the editor, build, and math input. Your files and projects are never deleted.

What happens when I exceed the AI token limit?

When you reach the limit, AI features (Axiom and OCR) pause until the next billing cycle. All other features including the editor and build continue to work normally. You can also upgrade to a higher plan to increase the limit.

Setup

Which TeX distribution do I need?

We recommend MacTeX (full, ~4 GB) or BasicTeX (minimal, ~100 MB). With Homebrew: "brew install --cask mactex". TeX64 auto-detects your TeX distribution on launch, so no path configuration is needed.

Which macOS versions are supported?

macOS 12 (Monterey) and later. Runs natively on both Apple Silicon (M1–M4) and Intel.

What if I see a Gatekeeper warning?

On first launch, macOS may show "cannot be opened because the developer cannot be verified." Go to System Settings > Privacy & Security and click "Open Anyway." It will launch normally after that.

Troubleshooting

SyncTeX is not working

Try a clean build (Cmd+Shift+B). If it still does not work, check Settings > Runtime to verify the synctex path is correctly detected.

"latexmk not found" error

Your TeX distribution is not installed or not in PATH. Install MacTeX (brew install --cask mactex) and restart TeX64.
