• Synonym必ずかならずNeutralCovers what happens inevitably, with no exceptions — objective certainty, or firm resolve; 「きっと」 adds the speaker's conjecture or hope.
• Synonym誓ってちかってWrittenSworn assurance, as in 「誓って嘘ではない」; carries an oath-taking tone, more solemn than 「きっと」, and can also take a negative.
• Synonym確かにたしかにNeutralConfirms a fact — 'indeed, certainly' — as in 「確かに受け取った」; 「きっと」 instead speculates about the unknown.
• Synonym相違なくそういなくWrittenWritten/formal prose for something verified beyond doubt, as in 「相違ありません」; common in documents and attestations, stiffer than 「きっと」.
• Synonym必定ひつじょうWrittenWritten/formal prose for what is destined to happen, as in 「敗北は必定だ」; old-fashioned ring, more assertive than 「きっと」.
• Synonym間違いなくまちがいなくNeutralLeaves no room for doubt, as in 「間違いなく来る」; more certain than 「きっと」, with less subjective guesswork.
• Related多分たぶんCasualThe colloquial opposite of 「きっと」's confidence: 'probably, maybe', with low certainty, as in 「多分来る」.
• RelatedおそらくNeutralAlso 'probably, I fear', with less certainty than 「きっと」; slightly more formal in tone than 「多分」.
• Related断じてだんじてWrittenWritten/formal prose, usually with a negative as in 「断じて許さない」; extremely strong, meaning 'never', unlike the conjecture of 「きっと」.
• RelatedまさにNeutralSays something is exactly right, as in 「まさにその通り」, or just about to happen; it asserts a fact, with no conjecture.
• RelatedまさしくWrittenWritten/formal prose asserting something is precisely so and beyond doubt, as in 「まさしく本物」; same root as 「まさに」, no conjecture.

Default to 「きっと」 for a confident 'surely' carrying the speaker's conjecture or hope. Use 「必ず」 for objective inevitability, 「間違いなく」 for no doubt at all, 「確かに」 to confirm a fact, and 「多分」 or 「恐らく」 for 'probably'.
