Yes. Core features including intuitive math input, build, SyncTeX, PDF preview, and on-device equation OCR are free. Optional Basic at $12/month and Pro at $25/month expand Axiom AI usage.

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

Yes. TeX64 works with an existing TeX distribution (TeX Live, MacTeX, or BasicTeX) and can install managed TeX Live after you approve the action. There is no proprietary document format or lock-in.

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. The editor, build system, PDF preview, SyncTeX, and on-device equation OCR work offline, and project data stays on your device by default. Axiom AI and downloading managed TeX Live 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 or later on Apple Silicon or Intel, and Windows 10/11 on x64. Building requires a TeX distribution; use an existing installation or approve a managed TeX Live install. Axiom AI and managed downloads require an internet connection, while equation OCR and other core features work 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. The editor, build, SyncTeX, PDF preview, intuitive math input, and on-device math OCR are included in Free with no credit card required. Optional Basic and Pro plans expand Axiom AI usage, and you are never 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?

Project files are stored locally on your device by default. Math OCR runs locally with bundled ONNX/Tesseract components, and selected screen or image captures are not uploaded. When you invoke Axiom, only the prompt and necessary project context are sent to the configured AI service. See the Privacy Policy for details.

Can I use it offline?

Yes. The editor, build, SyncTeX, PDF preview, intuitive math input, and math OCR work offline. Axiom AI and managed TeX Live downloads 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 AI allowance, Axiom pauses until the next billing cycle. Local OCR, editing, building, and PDF preview continue to work. You can upgrade to a higher plan to increase the Axiom allowance.

Setup

Which TeX distribution do I need?

TeX64 can use an existing TeX Live, MacTeX, or BasicTeX installation. You can also approve managed TeX Live setup from the app; TeX64 downloads it and installs it in an app-managed folder on your device.

Which operating systems are supported?

macOS 12 and later on Apple Silicon or Intel, and Windows 10/11 on x64. Building requires a TeX distribution; use an existing installation or approve managed TeX Live setup.

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 from Settings > Build Profile > Clean. If it still does not work, check Settings > Environment to verify the synctex path is correctly detected.

"latexmk not found" error

Your TeX distribution is not installed or not in PATH. Configure an existing distribution or approve managed TeX Live setup, then restart the build.
