Reported 87% bypass rate against AI detectors, a real, tested performance figure
Consistent feature set (humanization, detection, API) across paid tiers avoids feature-gating confusion
Affordable annual pricing ($5/month equivalent) provides real value for sustained use

Genuine 13% residual detection risk even at the reported 87% bypass rate — not a guarantee
Free trial is limited to just 250 words, providing minimal testing capability
Credits typically don’t roll over month-to-month, requiring careful usage planning

Largest user base and ecosystem of any AI assistant, with the most third-party integrations
Genuinely broad capability across writing, coding, research, and file analysis
Custom GPTs allow tailoring the assistant to specific repeated tasks
Frequent model updates keep it competitive on raw capability

Free tier has usage limits and access to a lower-tier model than paid plans
Can produce confident-sounding but incorrect information, especially without browsing enabled
Breadth can mean less depth than a tool purpose-built for one specific workflow
Data usage and training policies require attention for sensitive or regulated work
