## What is TrainVision?

Collect the machine learning datasets that don't exist yet.

TrainVision turns any iPhone or iPad into a field tool for building domain-specific ML training data — capture images, annotate them on the spot, and export straight to your pipeline.

General-purpose models perform well on common objects in controlled settings. They fail wherever their training data runs out — regional crop varieties, low-resource scripts, machinery and environments no web-scale dataset ever captured. TrainVision is built to collect exactly that data, in the real world where it lives.

Instead of gathering images now and annotating them later at a desk, your team captures and labels in one step. Every image is automatically tagged with GPS location, timestamp, and device info. On iPad, annotate precisely with Apple Pencil. And it all works offline — data is stored on the device and syncs to the cloud automatically when a connection returns, so you can work in fields, archives, or remote sites with no signal.

Because it runs on the devices people already carry, collection scales across distributed teams. Students, field workers, technicians, and researchers gather data naturally during their day — walking a vineyard, inspecting equipment, digitizing a manuscript. Coordinate hundreds of collectors across multiple sites from a single dashboard.

Collected data syncs to a central web dashboard, where admins manage projects, review and curate the incoming data, and export in standard formats — COCO, YOLO, Pascal VOC, and CSV — ready for any ML pipeline or platform.

KEY FEATURES
- Offline-first capture and annotation — no connection required
- Automatic metadata: GPS, timestamp, device
- Apple Pencil annotation on iPad
- Automatic cloud sync when you're back online
- Roles for admins and contributors — collect in the field, manage centrally
- Web dashboard for review, curation, and project management
- Export to COCO, YOLO, Pascal VOC, and CSV
- Built for distributed teams collecting at scale

BUILT FOR
- Archives & cultural heritage — handwritten documents, low-resource scripts
- Agriculture & environmental monitoring — crop disease, regional cultivars
- Robotics & autonomous systems — deployment-specific perception data
- Research labs — proprietary, domain-specific datasets

If the dataset you need doesn't exist yet, TrainVision helps you build it — from the field to your model.
