About
Refrazr is built by a team of engineers and NLP researchers who wanted AI-assisted drafts to read like a person wrote them. The pipeline is a single naturalness-focused rewrite pass over the whole draft, under a hard rule that no name, number or fact is changed. The full pipeline is described at /methodology.
What we do
Raw AI drafts tend to share a few habits: unnaturally uniform sentence lengths, overused transition phrases, symmetrical parallel clauses, and a narrow, repetitive vocabulary. Those habits are what make text read as machine-written.
Refrazr addresses this with one clean rewrite pass: the whole draft goes to the model in a single call, under a compact naturalness instruction — write this the way a sharp person actually would, uneven rhythm, plain verbs, one voice — with a hard rule that no name, number, date, or claim gets changed or invented.
We help content creators working with AI drafts, non-native English speakers who use AI to overcome language barriers, and marketers producing content at scale. The free tier is permanently free — 500 words per day, no credit card required.
Our approach
Simple paraphrasers change what the text says. Refrazr changes how it was written. The whole draft goes to the model in a single call, under one instruction — write this the way a sharp person actually would — with a hard rule that no name, number, date, or claim gets changed or invented.
After the rewrite, a light cleanup pass strips model preamble, normalizes spacing, and swaps stray em dashes — that's the whole post-processing layer.
We judge output with Claude Opus, blind, on a fixed corpus, on two questions: does this read like a person wrote it, and is every fact from the source still intact. We don't test against or optimize for any specific third-party detector, and we don't claim the output beats one.
We show a local readability check on your draft, using the same heuristic analysis as our free pattern checker. It is not a detector result. The pipeline and the benchmark behind it are fully documented — see our methodology page.
Who built this
We are engineers and NLP researchers working on how AI-assisted drafts can read like a person wrote them.
Most paraphrasing tools swap individual words and leave the sentence structure as it was. Refrazr rewrites the whole draft so that rhythm, wording and voice read naturally.
The current pipeline is a single naturalness-focused rewrite pass: one instruction to the model, one pass over the whole draft, and a light cleanup afterwards.
The current pipeline's quality bar is a blind read from Claude Opus on two questions — does this read like a person wrote it, and is every fact from the source still intact — not a score from any specific detector. We don't test against or optimize for GPTZero, Turnitin, Sapling, Originality.ai, or any other detector, and we don't claim the output beats one. The methodology and the actual benchmark numbers are published at /methodology — we do not keep this proprietary because confident results should be reproducible.
The pricing reflects our cost structure. Every request runs on DeepSeek's v4-flash model via OpenRouter, which costs a fraction of what frontier closed models charge per call. We pass most of that margin to users. Refrazr Pro is $6.99/mo. The difference comes from the model choice, not a gimmick.

Who uses it
AI drafts save hours of work, but raw AI output reads like AI output. Editors and readers notice. Refrazr converts AI-generated drafts into content that reads like it came from a skilled human writer — with natural rhythm, genuine variation, and no AI jargon.
Using AI to help express ideas in a second language is legitimate wherever the rules that apply to you allow it. Refrazr helps non-native English speakers smooth AI-assisted phrasing into natural, idiomatic English that reflects their thinking.
Marketing teams that use AI to scale content production need drafts that read well and convert. A Business plan with API access, for teams that need to process content programmatically, is coming soon.
Privacy
We don't store your text. The process is: receive text → rewrite → return result → discard. Nothing you paste into Refrazr is logged to a database, shared with third parties, or used for model training. The only metadata we log is what's required for billing: timestamp, word count, and success/fail status.
Read the full details in our Privacy Policy. The short version: your content is yours and we never see it after the request completes.
