Genuinely standing free tier (10,000 words/month, no expiration), not a limited-time trial
Dedicated Classroom and API tiers address specific institutional and developer needs
Regularly updated pricing structure suggests active ongoing product development

Pricing and word caps change frequently, requiring direct verification rather than trusting a static quoted figure
Like all AI detectors, accuracy isn’t perfect and results should be treated as one signal, not definitive proof
Institutional pricing (Classroom, API) requires direct contact rather than transparent self-serve rates

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
