One photo in. A factory-ready tech pack out.
Manual tech pack creation eats four to eight hours per style and demands Adobe Illustrator skills most first-time founders never had time to learn.
Drop in a photo — a flat-lay of your sample, a mannequin shot, a digital mockup, even a clean sketch — and Adstronaut writes the flat sketch, the bill of materials, the graded measurement table, the construction notes, and the Pantone colorways in three to five minutes.
The remaining ten to fifteen minutes is your review: typing the real supplier names from your factory, refining the exact measurements you took on your sample, adding any custom artwork or print placement.
The output is a clean PDF that opens in any browser and goes straight to your manufacturer. Built for indie streetwear founders, first-time fashion founders, and production leads tired of rebuilding the same document for every style.

Not just apparel. Built for footwear, leather, and knit too.
Generic apparel templates with the wrong fields do not survive contact with a real factory.
Adstronaut treats footwear, leather goods, knitwear, and bodywear as distinct document types — each with the AI-generated sections that product class actually needs. A footwear tech pack swaps in upper materials, sole unit specifications, and closure hardware where apparel would have sleeves and necklines. A leather goods tech pack adds panel callouts, hardware specifications, and lining details for a backpack or city bag. A knitwear tech pack ships with yarn specification, gauge and knit structure, and finishing sections specific to sweaters and cardigans.
Measurements stay graded to the relevant ASTM standard where one applies — D5585 for women's apparel, D5219 as the body-measurement basis, D6193 for stitch types.
Used by designers who launch sneakers one season and knit dresses the next without rebuilding the document each time.
Browse Sample Tech Packs
Every section your factory expects. At the depth your product needs.
A vague tech pack is the most expensive mistake a first-time founder can make. The factory cuts the wrong seam allowance, mismatches the trim, runs the wrong wash, and you pay for two more sample rounds before the garment ships.
Adstronaut writes the sections your specific product class needs — the flat sketch with annotated points of measure, the bill of materials with supplier and per-unit pricing fields, the size grading table with tolerance, the construction notes with stitch callouts, and the Pantone-coded colorways.
Knitwear adds yarn specification and finishing. Footwear adds upper materials and sole unit. Leather goods adds panel and hardware specifications. Nothing extraneous, nothing missing.
The document reads cleanly to anyone in apparel manufacturing — Bangladesh, Vietnam, Porto, Tiruppur, Istanbul, Guangzhou — without translation. Production teams who switched report first-sample revision rounds dropping from roughly three per style to under one.

Replaces Adobe Illustrator, Excel, and freelance tech pack fees.
The old workflow: hours in Adobe Illustrator on the flat sketch, a separate Excel spreadsheet for the bill of materials, a tech pack platform like Techpacker for organization, and a freelance technical designer when the deadline hits and the in-house skills run out.
Four tools, three skill sets, and a per-style cost that runs between $150 and $500 from a freelancer or $35 to $125 per user per month from a traditional PLM — plus onboarding fees that can run to $3,000 before a single tech pack is produced.
Adstronaut absorbs the four-tool stack into a single browser tool. About $3 to $7 per tech pack, no per-user seats, no onboarding fees, no vector software, no spreadsheets. The flat sketch is the part most other tools still make you produce yourself — Adstronaut writes it from your photo.
Best for founders and production leads whose bottleneck isn't team collaboration. It's the design-software step itself.

Tech pack questions, answered straight.
Real questions from indie streetwear founders, production leads, and first-time designers. Updated monthly based on support tickets.
Can an AI-generated tech pack actually be used by a factory?
Yes, when it includes the same components a manufacturer expects from any source. Production teams who switched to Adstronaut report sample-revision rates dropping from about three rounds per style to under one — roughly a 70% reduction. The format is what matters more than how it was produced: a clear flat sketch, complete points-of-measure callouts, graded measurements with tolerance, a BOM with supplier and quantity, and unambiguous construction notes. Factories don't reject AI output. They reject vague output.
I've never made a tech pack before. Is Adstronaut really for first-time founders?
Yes — this is the most common use case. Most first-time fashion founders skip the tech pack because they don't know how to make one, and then the factory ships the wrong garment. Adstronaut writes the first draft for you from a photo. You don't need to know what a BOM, a POM callout, or a grade rule is going in — the document explains itself in the editor, and the AI fills in the technical details. Most first-time founders are exporting their first finished PDF within an hour of uploading their first photo.
Do I need to know Adobe Illustrator or CAD to use Adstronaut?
No. You can build a complete tech pack without Illustrator and without CAD. The flat sketch is the part most other tech pack tools (Techpacker, Tukatech, traditional PLMs) still make you produce yourself in Illustrator first. Adstronaut generates the flat sketch from your photo. If you can upload an image, you can produce a tech pack. No vector software, no design-degree prerequisite, no fashion-school background — it's the most direct alternative to Illustrator for fashion tech packs.
Is Adstronaut an alternative to Excel and Adobe Illustrator for tech packs?
Yes. Excel + Illustrator is the traditional manual workflow — you draw the flat sketch by hand in Illustrator, build a separate spreadsheet for the BOM, then assemble both into a PDF. Adstronaut replaces both: the AI generates the flat sketch from your photo and auto-fills the BOM, grading, and construction notes in a single document you edit in the browser. For designers without vector skills (or designers who don't want to spend four to eight hours per style on the manual workflow), it's the most direct replacement.
Can Adstronaut make a hoodie, t-shirt, dress, or denim tech pack?
Yes to all four — and to every other common garment type. Adstronaut handles every standard apparel category, and we publish dedicated sample templates and guides for each: t-shirt tech pack, hoodie tech pack, dress tech pack, denim jeans tech pack, jacket tech pack, blazer tech pack, cargo pants, slip dresses, swimwear, activewear, and more. The AI detects the garment class from your photo and generates the appropriate manufacturing specs. Browse the rendered samples in the gallery above — graphic tee, oversized drop-shoulder hoodie, maxi slip dress, tailored blazer, high-rise denim, cuffed joggers — and download the PDFs directly.
Does Adstronaut work for footwear, leather goods, knitwear, and bodywear?
Yes, with dedicated product-class sections — not generic apparel templates with the wrong fields. Footwear tech packs use upper materials, sole unit, and closure hardware sections. Leather goods use panel callouts, hardware specifications, and lining. Knitwear adds yarn specification, gauge, and finishing. Bodywear ships with intimate-apparel construction specs. See the leather city backpack and women's canvas sneaker samples in the gallery for the actual section difference.
How much does a tech pack cost with Adstronaut compared to a freelancer or PLM?
About $3 to $7 per tech pack with Adstronaut. Freelance technical designers average $150 to $500 per style with three to seven day turnaround (Maker's Row 2026 rates). Traditional PLM tools like Techpacker run $35 to $125 per user per month, plus onboarding fees that can hit $3,000. For a 10-style collection: roughly $30 to $70 with Adstronaut, $1,500 to $5,000+ with freelancers, or $420 to $1,500 per year in PLM seat costs before any tech packs are produced.
What's the difference between a tech pack and a spec sheet?
A spec sheet is one section — typically one or two pages listing measurements and basic construction notes for a single garment. A tech pack is the complete production blueprint: flat sketches, BOM, grading across all sizes, trims, construction details, Pantone colors, artwork placement, care instructions, and fit log. A factory can produce a sample from a tech pack alone. A spec sheet is one piece of a tech pack. Read our full breakdown by garment type if you're unsure which one you need.
Is there a free tech pack template I can use?
Yes — Adstronaut publishes free sample tech pack templates for the most common garment types (graphic tee, drop-shoulder hoodie, maxi slip dress, tailored blazer, high-rise denim, intarsia crewneck sweater, leather city backpack, canvas sneaker, ribbed beanie, A-line mini skirt, cuffed joggers, utility cargo pant, oxford button-down). You can browse them in the gallery and download the rendered PDFs. To generate one for your own garment, upload a photo and Adstronaut writes a fresh tech pack in minutes — first one is free.
How long does Adstronaut take to generate a complete tech pack?
Eight to twenty minutes end-to-end. The AI generates the flat sketch, BOM, measurements, grading, and construction notes in three to five minutes. You typically spend another ten to fifteen minutes reviewing — typing supplier names, refining points of measure, adding custom artwork — before exporting the PDF. A freelance technical designer averages three to seven business days for the same output. Manual creation in Illustrator + Excel runs four to eight hours per style.
Can I edit the tech pack after Adstronaut generates it?
Every field is editable. Add or change BOM rows (supplier, quantity, unit, per-unit price). Adjust each point of measure with your own tolerances. Swap Pantone TCX colors per garment region. Rewrite construction callouts. Drop in custom artwork or print placement. Log fit revisions across sample rounds. Edits autosave continuously. Export as a print-ready PDF whenever you're done.
