## Products

### [VisionTagger](https://www.synendo.com/visiontagger/)

> Never tag photos manually again.

VisionTagger is a macOS app that uses on-device AI to generate titles, descriptions, keywords, and structured metadata for your images. Pay once, process unlimited images — no cloud uploads, no subscriptions, no per-image fees. Export XMP sidecars for Lightroom and Capture One, JSON/CSV for web pipelines, Finder tags, or write back to Photos. Everything runs locally on your Mac.

- **Platform:** Requires Apple Silicon Mac with macOS 26
- **Price:** €24.99
- **Markdown:** https://www.synendo.com/visiontagger.md

### [GD Studio](https://www.synendo.com/gdstudio/)

> Generative art, made to plot.

GD Studio (Generative Drawing Studio) is a macOS app for designing generative artwork for pen plotters. Choose from 50 patterns across 8 families, shape them with live controls, layer in text and imported SVG, turn a photo into plottable line art, and export plotter-ready SVG, PDF, or print — or plot straight from the canvas with Plotter Hub. Every pattern is built from continuous strokes, so the canvas is an honest preview of the pen's path.

- **Platform:** Requires macOS 15 or later
- **Price:** €24.99
- **Markdown:** https://www.synendo.com/gdstudio.md

### [Plotter Hub](https://www.synendo.com/plotterhub/)

> Plot over the network.

Plotter Hub is a self-hosted plot server for AxiDraw-class pen plotters, running on a Raspberry Pi. Drag and drop an SVG in your browser and the Pi drives the plotter locally via the official AxiDraw Python API — with layer-by-layer plotting, pen-change pauses, paper-size presets, optional vpype path optimization, a live pen-position cursor, and physical pause-button support. Free and open source under the MIT License.

- **Platform:** Requires Raspberry Pi OS
- **Price:** Free, open source
