HumanFlow vs BypassGPT

The free tier allows 150 words a month, and 80 of them in one scan. Eighty words is about three sentences — shorter than this paragraph.

Nothing in this category fails at three sentences. Every tool here, ours included, produces something plausible at that length, because the patterns that give machine writing away are patterns of accumulation: connectives that recur, sentences that converge on one length, emphasis that flattens across paragraphs. None of them can appear in eighty words. What the free tier demonstrates is that the service is online.

Our free plan takes 1,500 words in a single scan and 2,000 a month, which is enough to run a real essay through and read the result end to end. We are not being generous — we think the product survives being examined at the length people actually write at, and a sample too short to show a weakness is also too short to show a strength.

Flip between monthly and annual on their pricing page and the features listed against the same named plan change. Not the price, which is expected and fine — the contents.

That makes the page unreliable as a record, and it is the reason this comparison quotes fewer specifics for BypassGPT than for anything else in the table. We can cite a figure we read; we cannot cite a figure that depends on which toggle position we happened to screenshot. Where we were unsure, the table above says so rather than picking whichever reading suited us.

It matters beyond tidiness. A pricing page is the one document a vendor controls completely and the one a buyer is entitled to rely on. If it does not agree with itself, every other number the vendor publishes inherits the doubt — which is an uncomfortable thing to write on a page selling a competing product, so weigh it accordingly and check the page yourself.

BypassGPT advertises defeating specific named detectors, and offers a three-day money-back guarantee. Those two things sit oddly together, and the discomfort is worth naming.

A refund window is a real, enforceable promise about a company's own behaviour, and three days is short but honest. A claim about defeating a named detector is a promise about the behaviour of software built by someone else, which changes without notice and disagrees with itself on identical input. The first can be honoured. The second cannot be verified by the buyer, the seller, or us — within three days or ever.

We do not make the detector claim, which costs us customers who are shopping for exactly it, and we say so on every comparison page including this one. What we will state is bounded: rewriting for rhythm and specificity tends to lower detection scores, because that is what detectors read as human. It is not a guarantee, and it does not affect any obligation you may have to disclose AI assistance.
