You can still attach files, start an AI evaluation of a tender, and create a first bid draft without using the monthly capacity. Once the capacity is used, you need to wait until the next month or upgrade to continue in the agent chat or with Price Sheet Filling. The knowledge base, formal documents and integrations still require a paid plan.
