PQAI offers a free version that covers all the basics. But if you need a chat-based patent search experience or API access, upgrading to a paid plan is the way to go.
PQAI offers three upgrade options depending on your needs:
- PQAI+ – Available at $49/month for users who want a chat-based patent search experience
- Developer Plan – Starts at $199/month and includes 600 API queries per month
- Enterprise Plan – Designed for organizations with high API usage or advanced integration needs. It starts at $700/month and includes 3,000 API queries per month.
Whether you’re refining a single idea or running automated searches across a large portfolio, upgrading gives you the speed, depth, and scale you need to go further with PQAI.
