Every realize synonym belongs to one of two camps: becoming aware of something, where understand, notice, recognize and figure out fit, or making something real, where achieve and fulfill fit. "She realized her mistake" and "she realized her dream" use the same verb for opposite directions of thought.
Each camp gets another word for realize in its own list, along with options for realized and realizing, idioms for sudden understanding, and the money meaning bankers use.

Shades of noticing
The chip row climbs from chatty to formal, but each word also adds its own nuance. Catch on means you finally get something others already knew. Figure out means you solved it by thinking. Notice is about the senses: you saw or heard it. Recognize suggests you identify something as true or familiar, and it pairs well with feedback: I recognize the problem. Comprehend is the most formal and stresses full understanding, often of something complex.

In a personal essay, "Then I realized that I wanted to teach" can become "That was when it dawned on me that I wanted to teach." The idiom slows the moment down and lets the reader feel the shift.
Phrases for the moment it clicks
Sudden understanding has a family of idioms. It dawned on me is gentle, like sunrise. It hit me is sudden and strong. It sank in suggests slow acceptance of something hard. It clicked is casual and fits learning. It occurred to me is mild and polite, useful in emails: it occurred to me that we could meet online.
All of these make the idea the subject, so the person moves to the end or becomes me.
Achieving goals: the other realize
When realize means turning a plan into fact, achieve is the safe swap and fulfill suits dreams and promises. Attain is formal and fits levels or standards. Bring about fits changes. Avoid actualize in plain writing; it sounds like jargon. The achieve synonyms page has a fuller list for resumes and reports.
Mistakes and opposites
Know is not a direct swap, because realize describes the moment knowledge arrives, while know describes having it. I knew the answer and I realized the answer tell different stories; see the know synonyms page. Acknowledge means admit, often out loud, which is a step beyond realizing.
The antonyms are overlook and miss for not noticing, misunderstand for getting it wrong, and fail for the achieve sense.
- We overlooked a key detail.
- The project failed to meet its aims.
