**01** / Familiar

## Your hands already know it.

Menus, shortcuts, dockers and tools are where years of classic vector graphics taught you to look. Nothing to relearn, no week of training.

F6 Rectangle · F7 Ellipse · Y Polygon · F10 Shape · Ctrl+Q To curves · G Interactive fill · Ctrl+L Combine · Ctrl+J Options

### Precise

Measurements in mm, number fields that calculate (`297/2`), snapping to nodes, guidelines and the page.

### Fast

A native program in C++ and Qt 6. It starts in seconds and responds instantly, even with large documents.

### Open

PDF, SVG, EPS, DXF and all common image formats in and out. Scripts in JavaScript.

**02** / AI assistant

## Say it. It draws it.

The assistant works right inside your document. In the picture it was given a single sentence: “Put three small glowing stars in the sky and a subtle moon at the top left next to the title.” It looked at the poster, drew, and checked its own result.

- Draws real, editable vectors
- Operates TANGENTA: group, align, shape, trace, export
- Looks at the page and corrects itself
- Searches for images and the web, with author and licence
- One Ctrl+Z undoes the entire answer

**10** / Questions

## Good to know.

**Is the interface available in English?**

Not yet: the program interface is currently in German. Spell checking already covers English, French and German. Translations of the interface are welcome on GitHub.

**Does TANGENTA open .cdr files?**

Not directly yet. Save as PDF, SVG or EPS; TANGENTA imports these formats as editable curves.

**What does the AI assistant cost?**

Nothing from TANGENTA. With a Claude subscription (Pro or Max) and Claude Code installed, it runs on your subscription at no extra cost. Alternatively, use your own API key (Claude, OpenAI, Gemini, DeepSeek) or your own Ollama server.

**Does the assistant have to be allowed to change my document?**

No. Without the “darf ändern” (may change) tick, it only reads. And whatever it changes in one answer, a single Ctrl+Z undoes.

**Does TANGENTA run on a Mac?**

Today it runs on Windows and Linux. Qt makes a Mac version possible; it is on the wish list.

**May I use TANGENTA at work?**

Yes, without restriction. The GPLv3 only governs distributing modified versions, not using the program.
