About
Humanize AI text, rephrase a sentence, or fix grammar before you send it. SupWriter helps turn emails, articles, essays and everyday drafts into clearer writing on iPhone and iPad. Start with free credits and review the result before you copy or share it.
HUMANIZE AI TEXT
Make a stiff draft sound more natural. Choose a tone, purpose and language, then edit the result to make it yours. Some settings require an eligible paid plan.
PARAPHRASE AND REWRITE
Explore another way to say it. Rework a sentence or paragraph while staying in control of the final wording.
FIX GRAMMAR
Check spelling and grammar, compare your original text with the result, and make your final edits before sending.
CHECK AI WRITING ESTIMATES
Use AI Detect to review an estimate of how text reads to an AI detector. Scores can be inaccurate and are not proof of who wrote something.
BRING YOUR DRAFT
Paste text, dictate using the microphone, or import TXT, Markdown and PDFs with selectable text. PDF text extraction happens on your device. Scanned pages, photos and document layouts are not imported; there is no OCR.
KEEP YOUR WRITING CLOSE
Reopen recent results in History. Copy, share or export your writing. Sign in with the same SupWriter account to access your plan, credits and history on supported devices.
FREE CREDITS, OPTIONAL SUBSCRIPTIONS
Free access includes limited credits. Basic, Pro and Ultra plans offer monthly and annual billing. Basic supports up to 500 words per request, Pro 2,000 and Ultra 5,000. Credit allowances and localized prices appear before purchase. Annual subscriptions are paid upfront with their yearly credit allowance granted upfront. Eligible plans include personal writing style and advanced controls.
Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours before that period ends. Manage or cancel App Store subscriptions in your Apple Account settings. Existing subscribers manage billing through the provider where they subscribed.
An internet connection is required for AI tools. Review generated text for accuracy before using it.
