Formal Tone

Formal Writing Rules.
AI Doesn't Know Them.

AI can approximate formal language, but it consistently gets the register wrong. Legal writing, academic prose, and official correspondence follow conventions that are not interchangeable. The wrong level of formality in a contract, a journal submission, or a regulatory filing is not just a style issue. It signals that the author does not understand the domain. HumanTone rewrites your AI drafts to match the formal register of your specific context.

The Problem

AI Formal Writing Is Stiff, Not Correct.

01

AI formal register is generic, not domain-specific

When asked to write formally, AI increases sentence length, removes contractions, and adds elevated vocabulary. The result is generic formal writing that doesn't match any specific domain convention. Legal formal is not the same as academic formal. Academic formal in economics is not the same as in literary studies. Official correspondence formal varies by jurisdiction and institution. Generic formal writing signals that the author doesn't belong in the domain.

With HumanTone

Custom Instructions define the specific formal register for your context: "Formal language appropriate for US federal regulatory filings. Use defined terms consistently. Avoid contractions, colloquialisms, and informal qualifiers." HumanTone applies domain-specific formality rather than generic elevated prose.

02

Intrusions of casual language break the register

AI-generated formal content frequently contains register intrusions: contractions, casual transitions, informal qualifiers, and colloquial vocabulary buried in otherwise formal prose. "Additionally, it should be noted that..." followed by "this is basically the core issue" destroys the register in a single phrase. Formal writing is consistent throughout. A single casual intrusion signals carelessness or incompetence.

With HumanTone

HumanTone systematically identifies and replaces register intrusions. Custom Instructions can specify: "No contractions throughout. Replace informal transitions with formal equivalents. Flag and remove any colloquial vocabulary." The rewrite maintains formal register from the first sentence to the last.

03

Imprecise formal language creates legal and academic risk

In legal writing, precision is not a style preference. It is a requirement. "Shall" and "will" carry different obligations. "Including but not limited to" and "including" have different legal scope. In academic writing, imprecise claims create reviewability problems. AI formal writing uses elevated vocabulary without the domain-specific precision those words require. The language sounds formal but creates ambiguity where clarity is required.

With HumanTone

Custom Instructions can specify precision requirements: "Use 'shall' for obligations and 'may' for permissions. Define all key terms on first use. Avoid vague quantifiers." HumanTone applies these requirements to produce formal writing that is precise in the domain-specific sense, not just elevated in register.
