Comparison

Machine Translation vs Post-Editing (MTPE)

Raw machine translation gets you 80% there. The last 20% — accuracy, terminology, tone — is what post-editing fixes. Understanding the trade-off helps you choose the right workflow for each content type.

Machine Translation

Raw MT output, no human review.

Option A
vs

Post-Editing (MTPE)

MT output corrected by human linguists.

Option B
The verdict

Raw MT suits gisting and low-risk content. Post-editing (MTPE) is the sweet spot for scaling quality content — MT speed with human accuracy, at a lower cost than full human translation.
