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.
