Originality.ai Alternative
Originality.ai sells AI detection and plagiarism checks by the credit, for agencies and publishers. Here it stands beside Blurwrite: what each costs, what the free tier covers, where Originality.ai is ahead and where Blurwrite works differently.
The short version
Choose Originality.ai if you need a plagiarism check today, readability and fact checks in the same place, or detection in more than 13 languages. Choose Blurwrite if you want detection words in the plan (50,000 to 300,000 a month), a humanizer and a paraphraser with them, and the false positive rate on non-native writing is published per language.
The differences that decide it
- Credits or an allowance. Originality.ai counts every scan in credits, 2,000 a month on Pro, which is 200,000 words of AI detection or 100,000 with plagiarism. Blurwrite plans include a monthly pool of detection words, 50,000 on Basic to 300,000 on Pro, and word packs add to it.
- Detection alone or a writing toolkit. Originality.ai adds plagiarism, readability, grammar and fact checks. Blurwrite adds a humanizer, a paraphraser and a summarizer.
- How accuracy is reported. Originality.ai publishes its own accuracy claims and links third-party studies. Blurwrite publishes measured figures per language, including the false positive rate on writing by non-native speakers.

Questions before you choose
Is Blurwrite a good Originality.ai alternative?
It is if you want detection and rewriting in one plan: paid plans include a monthly pool of detection words, and the humanizer and paraphraser are included. If you need a plagiarism check today, Originality.ai has one and ours is still being built.
Is there a free Originality.ai alternative?
Blurwrite has a free tier with no card: one run a day on the detector, the humanizer, the paraphraser and the summarizer, and the detector reads the first 250 words. Originality.ai gives free users 3 scans a day of up to 2,000 words.
How much text does Originality.ai Pro cover?
2,000 credits a month. One credit covers 100 words of AI detection, so that is up to 200,000 words, or 100,000 when plagiarism is checked at the same time. Subscription credits expire each month.
Does Blurwrite check for plagiarism?
Not yet. The plagiarism check is coming soon and not live yet. Until then Blurwrite covers AI detection, the humanizer, the paraphraser, the summarizer and the grammar checker.
Which languages do they support?
Originality.ai states AI detection in 30 languages. Blurwrite detects in 13 languages, each calibrated on its own texts, with the measured figures on the accuracy page.
