techpack
“A full tech pack — construction notes, BOM, graded measurements, and export-ready PDF — generated from a single sketch in under 5 minutes. The same work costs $400-2,400 with a traditional technical designer.”
The Traditional Way
Tech packs shouldn't cost thousands.
A tech pack is the blueprint that turns a design into a manufactured garment. Without one, factories can't produce. But creating them has always been painful:
8 — 16 hours of work
A skilled technical designer spends 1-2 full days per garment documenting every construction detail, measurement, and material.
$400 — $2,400 per pack
At $50-150/hour for freelance technical designers, a single tech pack can cost more than the fabric for your first samples.
Human error in specs
Manual measurement grading, hand-typed BOM lists, and copy-paste construction notes introduce errors that cause costly production mistakes.
Weeks of back-and-forth
Designer sends sketch, TD asks questions, revisions follow, more questions. The communication loop stretches timelines by weeks.

4 simple steps
Upload or generate a sketch
Start from an AI-generated sketch, upload your own CAD flat, or create a tech pack manually from scratch.
AI analyzes your design
GPT-4o vision reads your sketch and generates 30-50 construction notes, a full BOM, graded measurements, and colorways — all in one pass.
Edit everything inline
Every field is editable. Drag construction markers on the sketch, adjust measurements, add BOM items. The AI gives you a head start — you refine.
Export production-ready PDF
One-click PDF export with cover page, flat sketches, construction details, BOM, and measurement spec sheet — ready to send to any factory.
Features
What you get
AI-Assisted or Manual
Start from AI analysis or build from scratch. Both workflows produce the same professional output.
Multi-Piece Detection
Designing a two-piece outfit? AI detects separate garments and creates independent tech packs for each piece.
Draggable Construction Markers
Every construction note has a visual marker on the sketch. Drag them to point exactly where the detail applies.
Auto-Grading Engine
Set a base size and the system grades all measurements across your full size range using industry-standard increments.
Normalized BOM
Bill of Materials items are auto-categorized into fabrics, trims, labels, and packaging with standardized material types.
Professional PDF Export
Factory-ready PDF with cover page, sketches labeled A/B/C, construction callouts, full BOM table, and measurement spec.
Stop paying thousands for tech packs.
Upload a sketch and have a complete, factory-ready tech pack in minutes — not days. Construction notes, BOM, measurements, and PDF export included.
