Copyleaks Alternative

Copyleaks answers the audit question: how much of this text looks AI-generated, and does any of it match an existing source. It stops there. DeAIze covers the detection and the edit that comes after it.

In short: Copyleaks is a detection platform aimed at institutions and businesses: it returns an AI detection result for a document and checks the same text for matches against published sources. DeAIze is a detect-then-rewrite tool: it highlights the sentences carrying the AI signal, rewrites the flagged ones, keeps a rewrite only when semantic similarity says the meaning survived, and re-scores the document. Neither proves authorship.

One flag, many sentences

DeAIze names the sentences that pulled the score up, so you edit three lines instead of rebuilding a chapter.

Proofreading, not just scoring

The rewrite pass changes the flagged sentences and leaves the rest of the document alone.

A meaning gate on every rewrite

Semantic similarity decides whether a rewrite survives, so a lower score cannot hide a changed claim.

What Copyleaks reports

Copyleaks is built around verification. Point it at a document and you get an AI detection result alongside plagiarism checks against published sources. For a school or a publisher screening a lot of text, that combination is the point: one pass tells you whether the writing looks machine-generated and whether it borrows from somewhere else.

What it does not do is edit. A report is the end of its job and the start of somebody else's. The flagged passages still have to be read, judged and rewritten by a person.

Where a detect-only workflow stops

A percentage is not an instruction. When a report says a large share of a chapter reads as AI-generated, the next hour goes on reading it line by line, guessing which sentences caused the result, and rewriting them by hand. It is slow, two editors will make different calls, and it is easy to over-correct — flattening a good paragraph because it sat next to a flagged one.

DeAIze splits the work differently. The detector does the locating, so the rewrite starts from the sentences that actually carry the signal instead of from the whole document.

How a detect-then-rewrite loop differs

The loop has three steps and one gate. Detect: the document is scored and every sentence is highlighted by AI probability. Rewrite: the flagged sentences are rewritten with more varied rhythm and plainer transitions, while unflagged sentences are left untouched. Re-score: the document is measured again so the before and after numbers sit side by side.

The gate is a semantic similarity check on each rewrite. If a new sentence drifts from the original meaning, it is discarded. Without that check, lowering an AI score is trivial and worthless, because the cheapest way to change how text scores is to change what it says.

What stays the same

Your argument, your sources and your structure stay yours. Uploads of .txt, .docx and .pdf keep their Word formatting — headings, fonts, styles and tables — so a rewritten .docx comes back as a document rather than as text to paste into a blank file.

Text is processed per task only. It is never used to train a model and never resold. When a piece of work sits under an NDA, that is usually the first question the client asks, and it deserves a straight answer rather than a marketing line.

Choosing between the two

If the job is auditing finished text — a compliance check, a submission review, a plagiarism question — a detection platform does that and DeAIze does not replace it. Source matching in particular has no equivalent here.

If the job is getting a draft from "reads machine-written" to "reads like the person who wrote it", a score is the start of the work rather than the end of it, and that is the gap DeAIze fills. Plenty of teams run both: screen with one, clean up with the other.

Detect, rewrite and re-check in one pass.

Frequently Asked Questions

Is DeAIze a replacement for Copyleaks?

Only for the rewrite half of the job. Copyleaks also matches text against published sources, which DeAIze does not do. If you need plagiarism checking, keep a plagiarism checker and use DeAIze for sentence-level detection and rewriting.

Does DeAIze check against real detectors?

Where third-party detector APIs are configured, DeAIze cross-checks against them, so a result does not rest on one model's opinion alone.

Can it handle a long document?

Uploads of .txt, .docx and .pdf are supported and Word formatting is preserved. Longer documents use more credits: Pro covers 10,000 words for $99.99, and credits never expire.

Will my text be used to train a model?

No. Text is processed per task only. It is never used for training and never resold.

Can DeAIze guarantee a particular Copyleaks score?

No. Detector output is a probability estimate that shifts with small edits, so no tool can promise a specific number.
