A complete embroidery digitizing suite
A native Rust engine, a modern interface in English, Arabic and French, and tools designed for real workshops.
Arabic and Latin lettering
Correct shaping, joins, minimum column width and dot size, so Arabic letters stitch cleanly at small sizes.
- 17 bundled SIL OFL fonts with pre-digitized embroidery glyphs
- Straight, arc and path text, kashida and bidirectional text
- “Arabic name in 5 minutes” wizard
- Interface fully translated, right-to-left in Arabic

AI designer
Bring your own AI: the model designs with Tarz's fonts, motifs and layout tools, and the built-in review checks hoop, overlaps, legibility, density and machine limits after every version.
- Claude, GPT, Gemini, Mistral, Grok, DeepSeek, OpenRouter, any OpenAI-compatible server, Ollama and LM Studio
- Live previews and a quality score for each version; follow-up requests in the same conversation
- MCP server for Claude Desktop, Claude Code, Cursor, VS Code, Codex and Gemini CLI; downloadable Claude Skill
- Keys stay on your computer; requests go directly to the provider you choose

Thread-level rendering with sheen on the fabric of your choice, before anything touches the machine.
