SupWriter
SupWriter combines a humanizer with an AI detector, paraphraser and grammar checker. It is aimed at academic, marketing and business drafts, with a stated emphasis on retaining meaning and voice. The official page advertises browser-extension, mobile, MCP and API access. Detector scores should be treated as uncertain signals, and the site asks users to follow school or employer AI rules. 300 free credits advertised; numeric paid billing terms were not sufficiently clear to verify.
