GPTKit reports approximately 93% accuracy based on testing 100K+ human and ChatGPT responses. The first 2048 characters of every request are free, including for guests; the Free Plan allows up to five requests per minute. Unlimited (Personal) costs $5 a month and supports two team members. Unlimited (Team) costs $10 a month, supports eight members, and includes API access. Unlimited (Institution) costs $20 a month, supports 20 members, and includes API access.
