Which plan fits your writing?
Start with the words you expect to rewrite each billing month and the tools you use most. AI detection is included in every paid plan.
Basic for students and occasional writers
Basic gives you 10,000 words a month for the humanizer and paraphraser, a practical fit for a few essays, assignments or posts. Use the humanizer to vary sentence structure and the paraphraser to explore wording while reviewing changes against your source. Keep the free grammar checker and word counter alongside them as you finish each draft.
Plus for daily writing and editing
Plus offers 25,000 words a month for the humanizer and paraphraser. Choose it when articles, client drafts or longer projects make rewriting part of your daily routine. Every paraphrasing mode and the paid humanizer controls are included, so you can adjust register, simplify a passage or try a different structure as you edit.
Pro for teams and developers
Pro provides 50,000 words a month for the humanizer and paraphraser and is the only plan with API access. Choose it for a larger writing workload or to bring the tools into your own workflow through the API. Compare its batch-check allowance, printable reports and priority processing below to see how they fit your work.

What makes an AI detector the best choice?
Look for published accuracy measurements, clear confidence ratings and sentence-level results. Blurwrite offers all three. For pricing, choose the plan that fits your humanizer and paraphraser usage; every paid plan includes AI detection.
What happens to unused words?
Your plan words reset at the start of each billing month. Top-up words are used after your plan words for the tool they were bought for, and they last 12 months from your latest top-up for that tool.
How does semester billing work?
Pay once for 4 months at a lower monthly rate. Your plan renews every 4 months until you cancel.
How much is too much on an AI detector?
Use the detector's figure alongside its confidence rating and sentence marks to decide which passages need review. For usage, every paid plan includes a monthly pool of AI detection words: 50,000 on Basic, 150,000 on Plus and 300,000 on Pro, and word packs add to it.
Is there a truly free AI detector?
Yes. Blurwrite offers the free detector check described above with no card needed. The grammar checker and word counter are also free and unlimited.
Can I request a refund?
Yes, on request. For a plan, ask within 14 days of the first payment of its billing interval; renewals are not refunded. An upgrade that changes the billing interval, such as monthly to yearly, counts as a first payment, so the difference charged can be refunded within the same window. Each word pack has its own window of 14 days, and words already used are deducted pro rata. Nothing is refunded automatically when you cancel or move to a lower plan. Read the refund policy for the terms.
