How to Create a Tech Pack with AI (Without Losing the Detail That Matters)

A tech pack is the document that stands between your design and a factory misreading it. It is the least glamorous artifact in the studio and the one that most reliably decides whether the sample that comes back is the garment you drew. The promise of creating a tech pack with AI is real but narrow: AI can draft the structure and the boilerplate fast, and it can save your technical designer hours of setup — but the detail that actually prevents a bad sample is still human work. Here is the honest workflow.

What a tech pack must contain

Before automating anything, be clear on what the document owns. A production-grade tech pack carries, at minimum:

• Bill of materials (BOM) — every fabric, trim, thread, interlining, label, hangtag, and packaging component, with supplier, colour, composition, and placement.
• Measurements and points of measure (POMs) — the graded measurement spec across the size run, with tolerances. This is the heart of the document.
• Construction details — seam types, stitch types and SPI, seam allowances, finishing, topstitching, hems, closures. The how, not just the what.
• Colourways — every approved colour combination, referenced to a standard (Pantone TCX, a physical lab dip), not a screen colour.
• Labeling and compliance — fibre content, care instructions, country of origin, size labels, and any market-specific regulatory marks.
• Callouts and annotated flats — front, back, and detail views with numbered callouts tying every construction note to a place on the garment.

Miss any of these and the factory fills the gap with a guess. The guess is rarely the one you'd have made.

Where AI drafts well

The parts of a tech pack that are structured and repetitive are exactly where AI earns its keep. From a design reference and a short spec, an AI workflow can:

• Scaffold the whole document — every section, correctly labelled, in the right order, so nothing is forgotten. The blank-page cost of a tech pack is real; AI removes it.
• Draft the BOM structure from the materials you name, with columns for supplier, composition, colour, and placement ready to fill.
• Propose a POM list appropriate to the garment class — a shirt, a trouser, a knit each have a conventional set of measurement points, and AI knows the standard list so your technical designer edits rather than remembers.
• Draft care and fibre-content labeling from the composition, flagging where market-specific rules apply.
• Generate first-draft construction notes for standard seams and finishes, which the technical designer corrects to the actual build.

This is genuine time saved. Getting to a 70%-complete, correctly-structured draft in minutes instead of an afternoon changes the economics of a large line.

Where the human review is non-negotiable

Here is the line you do not cross: AI drafts, a human owns. The failure mode of AI tech packs is confident, plausible, wrong specificity — a measurement that looks reasonable and isn't, a seam allowance the model invented, a tolerance that would never survive production. The garment doesn't know the number came from a language model.

Before any tech pack goes to a factory, a technical designer or pattern-maker must:

• Verify every POM against the actual pattern. Not spot-check — verify. Graded measurements are where AI is most confidently wrong.
• Confirm tolerances against your factory's real capability. A tolerance is a negotiation with physics and your specific supplier, not a default.
• Correct construction notes to the real build. The model proposes the standard seam; your garment may not be standard.
• Cross-check the BOM against confirmed sourcing. A trim in the BOM that your supplier research hasn't actually confirmed is a delay waiting to happen.

AI gets you a structured, 70%-done tech pack in minutes. The last 30% — the graded measurements, the tolerances, the construction reality — is the entire reason the document exists. Treat the draft as a head start, never a deliverable.

Exporting to editable XLSX and PDF

A tech pack has to live in tools your factory and your PLM actually use. The right output is an editable spreadsheet for the BOM and POM tables — real cells and formulas, so grading updates propagate and your technical designer edits in place — plus a clean PDF of the annotated flats and construction pages for the factory floor. Screen-shot tables and flat images are the wrong artifact; the person on the other end needs to edit the measurement, not retype it. A workflow that ships genuinely editable XLSX (not a picture of a spreadsheet) is the one that survives contact with real production.

The realistic verdict

Creating a tech pack with AI is worth doing for the scaffolding, the boilerplate, and the first-draft structure — the work that was never craft. It is not worth trusting for the measurements, tolerances, and construction detail that decide whether your sample is right. Use it to get your technical designer to the meaningful work faster, keep the human review absolutely fixed, and export to formats a factory can actually act on.
