OpenTikZ is a library and AI agent skill for producing paper ready TikZ figures for LaTeX documents. It offers copyable icons, editable templates and one skill that lets an AI agent draft or modify figures, so conceptual diagrams for research papers compile cleanly and stay in the vector, text based format that LaTeX users prefer. There are four ways to use it. A user can grab a single icon as a .tex file, SVG or PNG and include it with an input command, with no AI needed. A user can edit a template by telling the agent the change, and the agent edits the template and verifies that it compiles. A user can hand the agent an image of a figure and get editable TikZ back. Or a user can describe a figure in words and have the agent draft it from the library. Templates shown include a LoRA diagram, FlashAttention, a generative adversarial network, an agent tool use stack, distributed data parallel training, an encoder decoder, a ResNet residual block, an LLM serving stack and a flowchart with a decision and a loop. A shared palette keeps colors consistent across figures. It installs in Claude Code through two plugin commands that add the marketplace from GitHub and install the plugin, and other installation methods are described on the site. It is aimed at researchers and students writing papers who want diffable, native figures rather than screenshots. The site publishes no pricing, and the library and skill are presented as free to use.
