Use tool ↗About CoWriter AI
CoWriter is an AI writing app aimed at students: it drafts and rewrites text, checks grammar, runs plagiarism detection, and generates citations in APA, MLA, Chicago, IEEE, Harvard, Vancouver and more. It also markets what it calls AI Detection Proof output — text intended to pass AI-detection tools — alongside free generators for essays, research papers, stories, scripts and lyrics. The operator is ProtonLabs Technology Inc; it claims 100,000-plus student users and publishes no country. Two paid tiers run monthly or annually. The terms are unusually aggressive: all sales are final, no refunds or credits, and users are asked to waive the right to dispute a charge with their bank.

Pros & cons of CoWriter AI
Bundles the things a student actually opens five tabs for — drafting, citations, plagiarism check — into one $11.99 workspace, and the free citation generators are useful on their own. The terms are where this turns sour: no refunds under any circumstances and an explicit request that you waive chargeback rights. That, plus the AI-detection-evasion pitch, makes it a tool to enter with eyes open.

- Terms ask users to waive the right to dispute or charge back any transaction
