Comparing "gang" and "gangcai"

刚 (gāng) and 刚才 (gāngcái) are similar, but they have somewhat different uses.

Both Come Before the Verb, But Have Different Emphasis

刚 emphasizes something "just" happened

"刚" is actually an adverb, and it is placed in front of the verb. It emphasizes that the action just happened a short time ago. It is similar to the English "just."

The key here is that "a short time ago is relative, and determined by the speaker. For this reason, 刚 can indicate that something "just" happened 1 second ago, 5 minutes ago, 2 hours ago, 3 weeks ago, or even a year ago. The absolute time is flexible, but from the speaker's perspective, it feels recent.

• 我 刚 说过，不 想 再 说 一 遍。I just said it, and I don't want to say it again.

刚才 emphasizes "just now"

刚才 is a time noun (like 今天 and 现在), and it expresses that the time that has passed is really short, in near-absolute terms. We're talking no more than 1-30 minutes, in most situations. If it is placed before the verb, it emphasizes what happened in the time that has just passed. It is similar to the English "just now."
