ProfText
ProfText checks documents for vague language, patterns associated with AI-generated writing, and academic citation validity. Available on the web and through an API, it accepts text and offers a free tier with 30 clarity and detection rules. ProfText says free analysis runs in a browser Web Worker, so text stays on the user’s device and is not retained. The free plan allows unlimited analyses of up to 5,000 characters each, but excludes citation verification, AI rewrites, compliance checks, risk scoring, and shareable report links. Pro costs €9.99 per month and raises the analysis limit to 100,000 characters. It adds citation cross-checks against OpenAlex, rewrites with tone controls, compliance flags, risk grading, custom rules, and.txt and.docx uploads. Pro also includes CSV export, priority support, and report links that remain available for 90 days. Enterprise adds REST API access, bulk processing, SSO and team management, and dedicated support at a custom price. The site describes team workflows with roles, document versioning, comments, approvals, and analytics.
