🧩 OneShot Dataset Prep – Minimal Input, Maximal Output

OneShot Dataset Prep is a lightweight, web-based tool that transforms a single image into a complete, structured dataset – ideal for one-shot LoRA training, quick concept sets, and testing workflows.

Upload your image → smart crop & flip augmentation → instant ZIP download with 14 labeled images.

All processing happens locally on your server –
no GPU required, no cloud tricks, no nonsense.

“From one image to one dataset – minimal input, maximal output.”

✅ Project Status

All core features are finished and production-ready.
The project is now fully public and open-source:

• ✔️ Core Image Processing (Crop & Flip Logic)

• ✔️ Backend API (Flask-based ZIP generation)

• ✔️ Frontend UI (Tailwind uploader with matrix-style aesthetics)

• ✔️ Teamspace Support (Archive separation, access control, quota management)

🤝 Teamspace – Built for Collaboration

OneShot Dataset Prep includes integrated team archives – designed for shared projects, dev groups, and collaborative dataset pooling:

• ✅ Create and manage teams (permission-based)

• ✅ Upload directly into team storage via dropdown

• ✅ Each team can store up to 50 datasets, separate from personal quotas

• ✅ Team members automatically share access to team archives

• ✅ Visual feedback when storage limits are reached (upload lockout & highlight)

• ✅ Dedicated Team Archive page for clean management

“No more sharing by hand – just upload once and the whole team’s got it.”

🧠 Best Practice: One-Shot That Works

Yes, 1 image = 14 crops.
But for better real-world LoRA results, use two angles:

👉 Recommended Setup:

• 1x front-facing view

• 1x back-facing or alternate angle

This gives you 30 images (2 originals + 28 variants), improving generalization and spatial consistency – especially for characters.

“Two views, one dataset – double the context, double the performance.”

🚀 Public Release – Get Started Now!

The testing phase is over –
