How Machine Translation Post-Editing Changed the Way I Work (And What It Still Can't Do)

A few years ago, when I was studying English Translation and Interpretation, machine translation was mostly a joke among my classmates. We'd feed a sentence into an online translator, laugh at the result, and go back to doing it by hand. That's not the world I work in anymore.

Today, I use machine translation and AI tools as part of my process, not as something separate from it. But how I use them, and where I draw the line, has taken time to figure out.

Where Machine Translation Post-Editing genuinely helps

For long, repetitive business documents, MT output can give me a usable first pass. It handles predictable sentence structures reasonably well, especially in English, where the grammar is more forgiving. It saves me time on the mechanical parts of a job, so I can spend more of my attention on the parts that actually require judgment: tone, intent, cultural fit, and the specific vocabulary a client's industry expects.

I've also started paying closer attention to post-editing as a skill in itself, separate from translating from scratch. Reviewing and correcting machine output is not the same task as producing a translation from nothing, even though the two get lumped together sometimes. It requires a different kind of attention: catching errors that look fluent but are wrong, rather than catching errors that look obviously broken.

Post-editing: catching what the machine gets wrong.

Where it still falls short

Arabic and Turkish are where the limits of MT show up fastest for me. Both languages carry structural and cultural nuance that current tools tend to flatten. Formal register, regional variation, idiomatic phrasing, and the kind of implicit meaning that native speakers pick up instantly, these are the areas where I still find myself rewriting large sections rather than lightly editing them.

There's also the matter of context that lives outside the text itself: who the audience is, what the document is really trying to accomplish, what would sound stiff or careless in the target language even if it's technically "correct." A model doesn't know any of that unless I tell it, and even then, judgment calls still land on me.

Why I don't see this as a threat to what I do

I'll be honest: I don't think MT is going to replace translators doing careful, judgment-heavy work. But I do think it's reshaping what translators are asked to do day to day. The demand is shifting toward people who can work fluently alongside these tools, catch what they miss, and know when to set them aside entirely and just translate the sentence myself.

That's part of why I've been looking more seriously at machine translation post-editing and AI-assisted quality assurance as areas to build real skill in, rather than treating AI tools as something to resist or something to lean on uncritically. Neither extreme reflects how the work actually happens.

What this means for clients

If you're hiring a translator right now, it's worth asking how they actually work with these tools, not just whether they use them. A document that's been quickly run through MT and lightly reviewed reads differently than one that's been properly post-edited by someone who understands both the source and target language deeply. The tools are the same. The outcome depends entirely on who's using them and how carefully.

For me, that means staying involved in every step, letting technology handle what it's genuinely good at, and putting my own attention where it matters most: the sentences that need a human ear to get right.

If you're working on a document that needs more than a machine translation pass, I'd be glad to take a look.
