Align translated documents into TMX
Load a document and its translation: the aligner splits both into sentences, pairs them up and exports a TMX translation memory for Trados, memoQ or any CAT tool. You check and fix the pairs in a side-by-side grid — and the files never leave your computer.
Illustration: the review grid after automatic alignment — the translator joined two sentences into one, so row 013 looks suspect and row 014 has a gap. One merge fixes both.
What it does
From finished translations to a reusable memory
Automatic pairing
Both documents are split into sentences and paired by sentence length (the Gale–Church method), anchored on matching numbers and codes. Paragraphs are respected when their counts match.
Problems highlighted
Rows with a gap or a suspicious length ratio are flagged, and filters show only those — so you check the few doubtful pairs, not the whole document.
Fix with merge and split
Merge a cell with the one above or below, split it at the cursor, insert or delete cells — with undo for every step.
Common document formats
Word (.docx), PowerPoint (.pptx), XML, HTML, plain text and Markdown. The text is extracted right in your browser.
Save and continue later
Save the alignment as a project file and load it again to pick up where you left off.
TMX for any CAT tool
Export a TMX memory for Trados, memoQ, Phrase or OmegaT, or a tab-separated TSV. Incomplete rows are skipped and duplicates are counted.
Privacy
Your documents never leave your computer
Segmentation, alignment and the TMX export all run in your browser. The documents are not uploaded and no copy is kept on a server — which matters for client documentation you are not allowed to share.

FAQ
Questions about translation alignment
What is translation alignment?
Alignment pairs the sentences of a document with the matching sentences of its translation. The pairs become translation units in a translation memory, so earlier translations can be reused in a CAT tool.
How do I create a translation memory from old translations?
Load the original document and its translation, run the automatic alignment, check the flagged rows and export TMX. Then import the file into your CAT tool, or keep using it here.
How accurate is the automatic alignment?
It works best when the translation follows the original sentence by sentence. Pairing is based on sentence length and anchored on matching numbers and codes; rows with gaps or unusual length ratios are flagged so you can fix them before export.
Which file formats can I align?
Word (.docx), PowerPoint (.pptx), XML, HTML, plain text and Markdown. Older .doc or .rtf files can be saved as .docx in Word first; PDFs need to be converted to Word or plain text.
Can I use the TMX file in Trados or memoQ?
Yes. TMX is the standard exchange format for translation memories, so you can import the result into Trados, memoQ, Phrase, OmegaT and other CAT tools — or open it in the TMX editor here.
Are my documents uploaded anywhere?
No. Everything runs in your browser on your own computer, and nothing is sent to a server.
Can I stop and continue later?
Yes. Save the alignment as a project file and load it later. Every edit can also be undone.
