The mechanism
What the Falcon humanizer computes
A single rewriting pass on our AI server. The instruction accompanying your text is to rewrite it so as to accomplish the transformation the tool name implies, while preserving the original meaning and factual claims, and to return only the rewritten text with no preamble, commentary, quotation marks or markdown fence. Everything the tool does follows from that sentence: it is a constrained rewrite, not a summariser, not a fact checker and not an editor with an opinion about your argument.
Because the route is remote, the server terms apply: 5 runs per rolling 24 hours and an input between 1 and 12,000 characters. A 300 character instruction field is available and is applied to the whole run.
