Refrazr vs WriteHuman AI (2026): Requests vs Words, and What Each Ceiling Actually Costs You

WriteHuman prices itself the way most SaaS tools do: pick a monthly plan, get a quota, run out, wait or upgrade. What makes it worth a closer look isn't the pricing tier names — it's how the quota is actually shaped. WriteHuman doesn't just cap your words. It caps your requests, and then caps the words allowed per request on top of that. That second ceiling is easy to miss until you paste a long document and watch it get rejected.

Requests and words are two different ceilings

WriteHuman runs three paid tiers, verified directly against the current pricing page. Basic runs $12/mo (or $144/year) for 80 requests a month, 2 output variations per request, and a 600-word cap per request; Pro moves that to $18/mo (or $216/year) for 200 requests, 3 variations, and a 1,200-word cap. Ultra, at $36/mo (or $432/year), drops the request ceiling entirely — unlimited requests, 5 variations, a 3,000-word cap per request, and 1,000 MCP requests a month thrown in on top. AI detection checks and priority support come with all three.

The number that actually matters here is the per-request word cap, not the monthly request count. On Basic, a 600-word ceiling means a standard five-paragraph essay (700-900 words) already needs splitting into two submissions — each one consuming a separate request from the 80/month pool. Run enough longer documents through it and the 80-request allowance disappears faster than the headline number suggests, because you're spending requests on splitting, not just on volume.

Refrazr's free tier is 500 words a day, no signup, and the paid side is word packs that never expire: 3,000 words for $1.99, 10,000 for $3.99, 30,000 for $7.99. Pro is $6.99/mo for unlimited words. There's no per-submission word ceiling worth mentioning — the request body caps out around 100,000 characters, so in practice your allowance runs out before any single-paste limit does. If your writing comes in occasional long pieces rather than many short ones, that's a structurally different bill than WriteHuman's request-based math.

What WriteHuman does that Refrazr doesn't

Three real things, and none of them are marketing fluff.

A Chrome extension. WriteHuman ships a browser extension for real-time checking as you write, rather than requiring a copy-paste round trip to a separate tab. Refrazr is web-only.

Multiple output variations. Every WriteHuman request returns 2-5 rewritten versions (tier-dependent) so you can pick the one that reads best. Refrazr returns one rewrite per submission. If you want to compare phrasing options side by side, WriteHuman's approach does something ours doesn't.

A sentence-level AI-probability detector built into the same editor. WriteHuman highlights specific sentences by how "AI-sounding" they read, targeting what it describes as four patterns: template phrasing, predictable cadence, uniform sentence length, and mechanical transitions. Refrazr's free AI detector is a separate tool that scores a whole passage, not individual sentences within the editor you're rewriting in.

On WriteHuman's detector-pass numbers

WriteHuman's marketing states specific pass rates — 98% on Copyleaks, 97% on Turnitin and ZeroGPT. We're reporting that because it's what the company claims, not because we've verified it and not because we'd publish an equivalent number ourselves. Detectors retrain on their own schedule and nobody outside the detector company controls what a classifier does next month. Refrazr doesn't put a percentage on this page for the same reason we don't put one anywhere else on the site: a number like that is a snapshot of one test against one detector version, and it stops being true the moment either side changes.

What we do instead is publish how the rewrite actually works and let you judge the output on text you already know the sound of.

Which one to pick

Pick WriteHuman if you want multiple phrasing options per submission, a Chrome extension for in-the-moment checking, or you write in short bursts under 600 words where the request-based quota doesn't bite. Pick Refrazr if you write in longer, occasional pieces where a per-request word ceiling would force you to split submissions, if you'd rather buy words once than track a monthly request count, or if you want to try it before creating an account at all.

Both have free access. Paste the same paragraph into each and read the two outputs against your original before deciding — that tells you more than either pricing page does.
