On the Shape of Ink

Ada Byron Alan Lin

October 4, 2026

1 Introduction

A drop spreads until surface tension balances gravity:

γ κ = ρ g h(1)

In what follows we measure the curvature κ of drops on paper and show how the fiber density changes the final radius of the stain.

FAQ

Questions, answered

Do I need to install LaTeX?

No. Tex.ink runs in your browser and compiles on our servers with a full TeX Live 2026 distribution: pdfLaTeX, XeLaTeX, LuaLaTeX, BibTeX, Biber and thousands of packages are already there.

Can I import an existing project?

Yes. Upload a .zip of your sources, link a GitHub repository, or convert a Markdown file into LaTeX.

Is my work private?

Projects are private until you share them. Each compilation runs in an isolated sandbox with no network access, and you choose exactly who can view, review or edit.

How does the AI assistant work?

It is powered by Claude and only acts on the project you are working in. Every plan includes monthly AI credits; you review suggestions before they change your document. A project owner can turn AI off for a project.

Can I use Tex.ink from Claude Desktop or Claude Code?

Yes. Create a personal access token in your account and connect the Tex.ink MCP server: Claude can then list your projects, read and edit files, and compile.

Is there a discount for paying yearly?

Yes. Yearly billing saves 20% on Pro, Max and Team. For a 4-year commitment, we offer 50% off: contact us at support@tex.ink or with the form below.

Can I cancel anytime?

Yes. You can cancel from your account at any time, and your projects stay available on the Free plan.
