A GPTZero alternative for editing drafts (and when GPTZero is the better pick)

GPTZero is an AI detector: it estimates whether a model wrote a piece of text. DraftCheck is a linter, not a detector. It highlights the phrases that make a draft read as machine-written and tells you how to rewrite them, and it never guesses who wrote anything. Depending on the job, you can use it alongside GPTZero or instead of it.

When GPTZero is the better choice

• You need an authorship estimate. If the question is "was this submission AI-generated?", that is what GPTZero is built to answer. DraftCheck doesn't answer it.
• You work in education. GPTZero's pricing page lists LMS integration (Canvas, Google Classroom), team seats with shared billing, and a Professional plan that scans up to 250 files at once.
• You want other checks in the same tool. Its plan comparison also lists a plagiarism checker, grammar check, writing feedback and source finding with auto-generated citations, plus an API for developers.

When DraftCheck fits

• Editing a draft before it publishes. Each flag points at a sentence, names the habit ("it's not X, it's Y", a staged run-up, a chatbot sign-off) and says how to fix it. You get a to-do list for the edit, which a probability score can't give you.
• CI and agent pipelines. POST /api/check is free for up to 5,000 characters per call with no key. There's an MCP server at /mcp for agents, and an open-source CLI and GitHub Action that can fail a docs pull request above a score you set.
• Free, no signup. The browser checker runs on your machine, so the text you paste isn't uploaded. There's no account and no word quota.
• Deterministic and explainable. The same text always gets the same 0-100 score, and each flag comes from a named rule you can read on the patterns page.

DraftCheck can't tell you whether a model wrote something, and it never claims to. A carefully edited AI draft can score 0, and a person who writes "in today's fast-paced world" gets flagged. Its rules are written for English prose. If those limits rule it out for your job, a detector is the right tool.

Side by side

Using both

The two tools answer different questions, so they don't conflict. A common split: writers and editors run DraftCheck while revising, and whoever needs an authorship signal runs GPTZero at intake. Don't read one tool's result as a prediction of the other's. A low DraftCheck score says the text avoids common AI-writing habits; it says nothing about how a detector will score it. And whichever detector you use, treat its result as one signal and have a person review anything flagged.
