The Short Answer: Which AI Tech Pack Route Fits You

You have a description and need a draft today: Kōbō's free AI tech pack generator - paste a sentence, get a multi-page draft with a graded measurement spec, BOM, construction details and an annotated technical flat. Free, no signup.

You manage styles in a PLM and make tech packs every week: AI generation from real product data - Kōbō's in-app tech pack automation builds versioned, factory-ready packs from your actual styles in 8 seconds, in 13 languages.

You're early-stage and want AI assists inside an affordable PLM: OnBrand PLM - a reasonable entry point with AI-assisted tech pack tooling at accessible pricing.

You want structure, not AI: Techpacker or a free template - card-based tech pack building, or our free tech pack template builder if you'd rather own the document.

You're still figuring out the garment: ChatGPT or any capable chatbot - great for thinking through construction and materials - just don't send the chat transcript to a factory.

What AI Can and Can't Do in a Tech Pack

A tech pack is two things at once: a structured document and a set of decisions. AI is genuinely good at the first. Given a decent garment description, current models produce industry-standard points of measure with sensible grade rules and tolerances, a bill of materials that remembers thread, labels and polybags, construction callouts a factory understands, and packing instructions. That's the part that used to eat hours of a designer's week, and it's the part every tool on this page automates to some degree.

What AI can't do is know your decisions: your fit block, your approved suppliers, the tolerance your factory actually holds, the label content your markets legally require. Every option below - ours included - produces something a designer reviews, not something that skips the designer. Anyone selling AI tech packs as "no expertise needed" is selling the wrong thing.

The Options in Detail

1. Kōbō's Free AI Tech Pack Generator

Full disclosure: this one's ours, and we built it because we wanted a working answer to "can AI make a tech pack?" rather than a landing page about one. You describe your garment, pick your colourways, and get a multi-page draft in about a minute: cover page, annotated technical flat (front and back, drawn by AI with construction callouts), graded measurement spec with POM codes and tolerances, component-level BOM, colourway applications, care and labelling, packing instructions, and a list of every assumption it made. Download as PDF, free, five per day, no signup.

Its honest limitation is the same as any text-to-document tool: it works from your description, so everything is a well-informed industry-standard assumption. It tells you what it assumed, which makes the review pass fast, but a review pass is still required.

2. AI From Real Product Data (Kōbō In-App)

The step-change happens when AI works from your actual styles instead of a description. Inside Kōbō, tech pack automation reads the real style record - sketches, measurements, components from your library, approved colourways - and generates complete, versioned, factory-ready tech packs with technical views and annotations in about 8 seconds, in 13 languages, with AI completeness checks flagging what's missing before a factory has to ask. Because it's built on live data, the pack updates when the style does, which is the thing no description-based generator can offer.

3. OnBrand PLM's AI Tech Pack Tools

OnBrand PLM has leaned into AI-assisted tech pack creation as part of its pitch to early-stage brands, and it deserves credit for that focus: accessible pricing (from around $79 per user per month), quick setup, and tooling aimed at getting a first brand out of spreadsheets. If you're an early-stage team already evaluating OnBrand as your PLM, its AI tech pack features are a sensible part of that package. As with any entry-tier product, check which AI capabilities sit in which pricing tier, and see our Kōbō vs OnBrand comparison for how the two platforms differ more broadly.

4. Techpacker

Techpacker remains the reference point for lightweight tech pack creation: a card-based builder with template libraries that freelancers and very small teams genuinely like, from around $49 per user per month. Its strength is structured manual creation rather than generation - you build the pack, it keeps you organised. For a solo designer who wants control over every field and doesn't need PLM depth, that's a feature, not a gap.

5. Asking ChatGPT (or Claude, or Gemini)

The DIY route, and more useful than tool vendors usually admit. A general chatbot is excellent at the thinking layer: what seams suit a heavyweight jersey, what a sensible size range looks like, what belongs in a BOM for a padded jacket. Where it falls down is the document layer - you get prose, not a graded measurement table; formatting drifts between styles; and nothing stops a confidently wrong measurement from landing in the middle of an otherwise sensible answer. If you go this route, use it to draft thinking, then rebuild into a proper structure - our free template builder exists for exactly that.

How We Built Ours (Briefly)

Because "AI generated" can mean anything, here's what ours actually does: a frontier language model drafts the structured document against the same section schema Kōbō uses in-app (cover, technical views, POM, BOM, packing, notes), with a hard rule that it only uses colourways you chose and lists every assumption it makes. A separate image model draws the technical flat the same way our in-product automation does - clean line art with annotation callouts built from the generated construction details. No templates pretending to be AI, and no AI pretending to be a finished spec.

Frequently Asked Questions

Can AI actually write a usable tech pack?

Yes, to draft standard. AI reliably produces the structure a factory expects - graded points of measure with sensible grade rules, a complete bill of materials, construction callouts, care and labelling. What it can't know is your fit block, your approved suppliers, or your tolerances, so every AI draft needs a designer's pass before it goes anywhere near production. The honest framing: AI removes the blank-page hours, not the expertise.

What is the best AI tech pack generator?

It depends what you're starting from. If you just have a written description and want a full draft now, Kōbō's free AI tech pack generator produces a graded measurement spec, BOM, construction details and an annotated technical flat with no signup. If you already manage styles in a PLM, AI generation from your real product data is stronger - Kōbō's in-app tech pack automation builds versioned, factory-ready packs from actual style records, and OnBrand PLM offers AI-assisted tech pack tooling for early-stage brands. General chatbots like ChatGPT are useful for brainstorming but produce unstructured documents that factories can't work from directly.

Can I just ask ChatGPT to make a tech pack?

You can, and for thinking through a garment it's genuinely useful. The gap is structure: a factory needs a graded measurement table with POM codes and tolerances, a component-level BOM, and consistent formatting across styles - a chat reply gives you prose you then have to rebuild into a document. Purpose-built generators exist to skip that rebuilding step.

Is an AI-generated tech pack safe to send to a factory?

As a first sample brief, with review - yes. Check the measurements against your own fit block, replace assumed materials with your approved suppliers, and confirm labelling for your markets. Treat the AI draft the way you'd treat a junior designer's first pass: the structure is right, the specifics need your eyes.

How is a free AI generator different from AI inside a PLM?

A free generator works from a text description, so everything is a well-informed assumption. AI inside a PLM works from your real data - actual measurements, your component library, approved colourways, past styles - so the output is production-grade rather than a draft, stays versioned, and updates when your data changes. The free tool is the fastest way to see what AI drafting feels like; the PLM is where it becomes part of how you work.
