DocHarbor
Engineer once. Deliver everywhere.
The next-generation AI platform for engineering. Any language, 100% of the format kept.
Supplier files still become yours by hand
Drawings, specs and manuals arrive in Chinese, German, Japanese or English. Turning them into your own documents takes people in several languages, and the department is always behind.

jobs.smartrecruiters.comSame pages, same layout, another language
Files from our pilot workspace, exactly as DocHarbor delivered them. Visual match: each page pair compared with the text blurred out, so it counts what moved (photos, graphics, colour blocks, rules), not which language the words are in.
Your format, kept 100%.
Not a lookalike: the same file, in another language.
of the file format, kept
Same type, same pages, same lines, same dimensions.
Every file comes back as itself: Word stays Word, Excel stays Excel.
pages in, pages out
ruling lines back in place
CAD dimensions identical
CAD geometry entities identical
728 pages: EMKA product catalogue, Chinese to English. Ruling lines: a 15-page register specification. Dimensions and geometry: a public DXF floor plan (skymakerolof/dxf, MIT licence). The proof follows below.
Even scans, in bulk, original format out
Scanned national standards come back as the same pages in English. The seal is recognised and kept where it was.
Seal keptFrom the de-identified trial workspace: Chinese national and industry standards (GB/T, JC/T, JG/T, JGJ), 21 of them pure scans.
The grid lands where it was
Red: the 26 ruling lines of a Chinese register specification. Blue: the same lines in DocHarbor's English output. They sit on top of each other.
Pages in, pages out. Every page break where the source had it.
Ruling lines in place across all 15 pages, within 0.6 pt.
Characters in one cell. English runs longer, so DocHarbor re-wraps it inside the same cell.
Register 6500, source and output
Every dimension, unchanged
text labels translated
dimension strings identical in text, position and height
geometry entities identical
Public floor plan (skymakerolof/dxf, MIT licence), real DocHarbor output; the Japanese output keeps the same 63 / 63.
Upload, compare, review, deliver
DocHarbor
A working replica of the DocHarbor workspace. Documents, pages and glossary terms are from the pilot workspace; the review item and glossary statuses are product demo data.
Built for AI agents, and for your team

Upload, compare, review, deliver: the workspace above.
On-premises
The whole platform runs inside your own network. Files never leave it.
700 pages. Five minutes.
Measured: a 700-page document, fine translation, in five minutes. A typical document is done in one to two.
At that rate, DocHarbor could have delivered 0 documents since you opened this page.
Semantic compression
The whole document's meaning is compressed once; every agent works from it in parallel. Long documents don't slow us down.

Engineering without borders.
Suppliers write in one language, customers read in another. Documents should cross borders as easily as engineers do.
One AI platform for every engineering company
Module by module. Multilingual documents are the first, ready for market; every module after it works on the same documents.
Multilingual documents
Supplier files become your own documents, in any language, 100% of the format kept.
Document management
Every drawing and document of a project in one workspace, every version kept.
Drawing to product
One drawing → parts, assembly, simulation, report and G-code.
Every module, one AI platform
Simulation, reports, machining and more, for every engineering company.
Built for every engineering company
The people who use it
Documentation, translation and document-control teams turning supplier files into their own.
The people who sign off
The department head, who answers for every package that goes out.
Why it keeps coming back
Drawings are revised and re-issued many times per project. Every revision goes through DocHarbor again, and document control keeps each version.
