The word intelligence has several related meanings. It can refer to a person’s ability to learn, reason, understand, solve problems, and use knowledge. It can also mean information gathered about a situation, especially in military, government, or business settings.
For mental ability, words such as intellect, cleverness, reasoning, understanding, insight, and wisdom may work. For information gathered through investigation, information, findings, data, reports, or intelligence reports may be more precise.
The best synonym depends on what kind of intelligence you mean. A person can have strong reasoning without having extensive knowledge, while wisdom usually involves judgment developed through experience.

Assuming intelligence always means IQ

Writing Tips
Use intelligence when you want a broad term for mental ability. If the exact ability matters, a more specific word can make your writing clearer.
For example, use reasoning for logical thought, insight for deep understanding, wisdom for experienced judgment, and ingenuity for creative problem-solving.
In professional writing, acumen can be more precise when discussing expertise in decision-making:
Her financial acumen helped the company manage risk.
For academic or scientific writing, cognition, reasoning, or mental ability may be more precise than the broad word intelligence.
If you mean collected information, avoid replacing intelligence with intellect. In that context, information, data, findings, evidence, or reports may be appropriate depending on what the information actually represents.
