SupWriter

SupWriter takes drafts written with AI and rewrites them so they read like a person wrote them — natural tone, clean grammar, and your original meaning intact. A built-in detection check screens results against major AI detectors such as Turnitin, GPTZero, and Originality.ai. Built for students, marketers, and founders who draft with AI but need polished output. Works on web, mobile, Chrome extension, API, and MCP for AI agents. Free plan included; paid tiers from $9.99/month.
