A tech pack is the document that tells a factory exactly how to make your product. Building one by hand takes hours and leaves room for the small errors that ruin a sample. An AI tech pack generator does the heavy lifting: you give it a design, it drafts the technical file. This guide explains how that works and what to look for.
What an AI tech pack generator does
A tech pack generator turns a design input into the standard sections a manufacturer needs:
- Technical flats drawn from your sketch or photo
- Points of measurement across your size range
- Bill of materials for fabric, trims, and hardware
- Construction details and callouts
- Colorways and labeling
The AI handles the first draft of each. You review and edit. New to the format? Start with what a tech pack is and our step-by-step on how to create a tech pack.
Why generate one with AI
Speed
What takes hours by hand takes minutes. For a brand iterating on several styles, that difference compounds fast.
Fewer errors
Manual measurement charts are where mistakes hide. Generating the spec from a single source keeps the numbers consistent across sizes.
No technical drawing skill required
You do not need to be a technical designer to produce a clean flat. The AI drafts it, you adjust.
What a good generator gets right
Not all AI output is production-ready. The difference between a usable tech pack and a pretty picture comes down to a few things:
- Editable output, not a flat image. You will always need to change something.
- Real measurements, graded across sizes, not placeholder numbers.
- A path to production. A tech pack exists to get made. The best tools connect straight to a manufacturer.
How Aria does it
Aria, Tchpack's AI assistant, builds the full tech pack from a sketch or photo. It researches the construction details, drafts editable flats, generates the measurements and bill of materials, and assembles a production-ready document. Then it matches you with vetted manufacturers to make it. You can run Aria on the web, inside Adobe Illustrator with the plugin, or in the app.
