What does "ok" mean in a text?
What "ok" usually means
"ok" is the most common one-word reply there is, and for most people it's a shrug of acknowledgement. They're busy, the message didn't need a paragraph, and "ok" is faster than typing "sounds good, see you then". If you'd sent "meet at 7?" and got "ok", nothing is wrong.
The reason it feels loaded is that we read short replies through whatever mood we're already in. Tired or anxious, "ok" sounds clipped. Calm, it sounds like agreement. The word didn't change; you did.
When "ok" is a full stop
There are a few situations where "ok" really is doing more than acknowledging:
- It arrives right after an argument or a tense exchange, where you'd expect either an apology or a pushback.
- It replaces a longer reply this person would normally give. If they usually write two lines and today it's two letters, that's a shift.
- It's "ok." with a period from someone who never uses periods, or "Ok" with a capital from someone who never capitalises.
- You asked a real question that needed an answer and got "ok" instead of one.
In those cases "ok" usually means "I'm done with this for now". That is not the same as "I'm furious" or "we're over". It's closing the door on the topic, often because they need a break from it.
"ok" vs "okay" vs "k" vs "kk"
People read a lot into the spelling, and there is a rough pattern, though it varies a lot by person and age.
- "okay" reads the softest. The extra letters signal a little effort and usually a little warmth.
- "ok" is neutral. The default.
- "kk" is friendly and casual, common between friends. It almost never carries an edge.
- "k" is the one most people find cold, because it's the least effort possible. From some people it's just how they type; from others it's pointed. See the guide on "k".
Who sent it matters more than the word
A partner sending "ok" after you've asked about plans is different from a partner sending "ok" after you've said something that hurt. A boss sending "ok" is almost always just approval. A friend who always sends "ok" is being themselves.
The most useful question isn't "what does ok mean" but "is this how this person normally texts, and what happened just before?" If both are normal, take it at face value.
What to say back
If it feels neutral, you don't need to reply at all. If it landed after tension and you don't want to leave it there, one of these keeps the door open without pushing:

Common questions
Is "ok" passive aggressive?
Not by itself. "ok" becomes passive aggressive only in context: after a tense exchange, or when it replaces a fuller reply that person would normally give. From most people most of the time it's simple acknowledgement.
What does "ok." with a period mean?
From someone who normally uses periods, nothing. From someone who never does, the period usually signals finality: they're done with the topic. Look at their usual style before reading into it.
Should I reply to "ok"?
If it was acknowledging plans or information, no reply is needed. If it came after conflict and you want to keep talking, a short, warm message that doesn't demand a response works best.
