Use case

Natural rewrites for
Grant writers.

If you draft grant proposals with an assistant, you've probably noticed the output reads formulaic — the same hedged phrasing reviewers see in a hundred other applications. For grants, the real risk isn't a detector; it's a proposal that sounds generic when funders want specificity and a credible voice. This page is the honest version of what a humanizer does for grant writers, and where the line is.

The problem

  • AI-assisted proposals read generic, formulaic, and interchangeable
  • Reviewers and program officers notice a flat, machine-like tone
  • Funders increasingly ask applicants to disclose AI use

How Humanizer helps

Humanizer rewrites text for natural rhythm and less mechanical word choice, so a draft reads like a real organization wrote it rather than a template. Its "Sound like me" personas learn from a few samples of your own proposals, helping the output carry your program's actual voice instead of stock nonprofit phrasing. Every rewrite shows a Sapling-based detector score for transparency. It still can't supply the specifics — your outcomes, budget logic, and evidence are what make a proposal credible, and those have to come from you.

Where we stand A humanizer improves how a draft reads; it does not make a weak proposal fundable. If your funder requires disclosure of AI use or attests that the application is your own work, you are accountable to that, and disguising AI to evade it is a violation that's on you. Where this is legitimate: polishing your own draft toward a natural, specific voice. We don't claim to pass any specific detector, and no tool can guarantee that.

FAQ

Questions, answered.

It rewrites for more natural rhythm and can match your own voice from samples. But specificity — real outcomes, data, and budget logic — still has to come from you.
