Knowledge loss
Expert know-how lives in people’s heads. When they move on, it leaves with them.
AI documentation and 3D work instructions
Technical documentation that keeps up with your engineering.
Draft manuals from your PDFs and engineering data, and add a 3D model for visual work instructions. When a part changes, see every page it touches. Your experts approve every release. Share it publicly or keep it private.

Engineering files become a coupling-inspection guide for the CP-200 pump. A second request creates a PDF manual from the same model and instructions. The yellow coupling guard is replaced with a stainless-steel version. An input above the machine types “Update the documentation.” As the documents appear, connecting lines carry pulses from the revised guard to the maintenance manual, parts list and service instructions in turn. Each arriving pulse highlights the affected content, advances the document to revision 03 and reveals a checkmark. The revised machine remains connected to all three updated documents beneath “Every output. One truth.” Illustrative documentation workflow with authored geometry states and document changes, not a live generation or automatic publication. Experts review source facts, visual actions and revisions; CP-200 is a demonstration identifier.

Technical knowledge management
Your technical knowledge is scattered across files and tools. TwinWorks puts it in order.
Manuals, procedures, parts lists, training, CAD models, videos and expert notes live in different folders and apps. TwinWorks reads them, finds what belongs together and links every block to its source.
Documentation lag
Engineering releases revision C while the manual still describes revision A.
Format chaos
PDFs, binders, videos and drawings drift apart, and local copies multiply.
Compliance risk
Audits need controlled instructions. Outdated pages add quality and review risk.
Technical documentation platform
One approved source for all your technical documentation. Manuals, 3D instructions and training come from it.
Bring what you have. Experts approve what goes out.
Your sources, connected
Manuals, 3D models, schematics, narrated video, source code and your experts’ know-how.

Engineering change impact
Change a part once. See every document it touches.
TwinWorks finds the documents linked to the changed part and sends each suggested update to the right expert. Nothing is published until they approve it.

Why TwinWorks
TwinWorks compared with a CCMS, a work‑instruction tool and generic AI
Technical authoring and frontline execution are often managed separately. TwinWorks connects both to the engineering data and reference documents that define the product.

Frequently asked questions
What is TwinWorks?
TwinWorks turns CAD, drawings and manuals into technical documentation and 3D work instructions, and keeps them current when the product changes. It brings 3D models, engineering data, and existing PDF or Word manuals into one documentation workspace. Teams use it to create manuals, interactive work instructions, training material, and execution reports; your experts edit, review, and approve every release.
What is technical documentation software?
Technical documentation software helps companies create, manage, and deliver the documents that describe how a product is built, operated, and maintained: manuals, work instructions, SOPs, troubleshooting guides, and training material. TwinWorks uses AI to prepare review-ready drafts from linked manuals and parsed engineering data. Experts edit, review, approve, version, and publish technical-document revisions.
What sources can TwinWorks work from?
TwinWorks imports existing PDF or Word manuals into editable drafts and uses them as reference sources. It reads engineering structures from QElectroTech, KiCad, 3DXML, and STEP or STP files; STEP import is in beta. For interactive 3D work instructions, it accepts OBJ, FBX, GLB, self-contained GLTF, and USDZ models. AI procedure drafts use reference PDFs. Imported models provide geometry and available assembly structure; authors create or review visual actions, with CAD-aware assistant proposals available in the editor. Procedures can also be written without a 3D model.
Does TwinWorks export S1000D?
Yes. TwinWorks exports descriptive and procedural S1000D data modules next to its web and PDF publications. Tell us which S1000D issue and business rules (BREX) you work to, and we’ll confirm the setup with you.
How does TwinWorks reduce documentation errors?
TwinWorks keeps content in reusable modules with revision history and a record of where each part came from. When a source changes, it shows the pages that depend on it and flags broken references, outdated embedded procedures, and shared dependencies for expert review. When a procedure is carried out, it records step status, duration, comments, and optional photos.
Which industries is TwinWorks built for?
TwinWorks is built for industrial manufacturers whose documentation is mission-critical, such as aerospace and defense, machinery and equipment, robotics, and energy. Its workflows center on structured content, expert review, and revision history.
How is TwinWorks different from a CCMS or a work-instruction app?
A CCMS manages structured manuals; a work-instruction app runs procedures on the shop floor. TwinWorks connects both to engineering: manuals and 3D work instructions come from the same reviewed source, and a product change shows every document it touches. See the comparisons.
What devices can teams use to view TwinWorks documentation?
Published documentation opens in the TwinWorks web viewer in a browser, and manuals can also be published as PDF. AR guidance is a limited beta for prepared setups.
Is TwinWorks free for universities and schools?
Yes. Education licenses are free for teaching, student projects and non-commercial research at universities, engineering schools and technical colleges. See how to apply.
Is there a free plan?
Yes. Free includes 500 AI credits to start, public publishing and PDF export, for up to 4 products.
How much does TwinWorks cost?
Free costs nothing and needs no credit card. Paid plans and their prices are in the app: sign up free to see them. Need a formal quote for your purchasing team? Ask us for one.
Can we pay by invoice?
Yes. Starter, Business and credit packs are bought online: checkout takes your company name, address and VAT number, and every payment comes with an invoice. You can also pay by bank transfer against an invoice.
