No. The plugin only searches: it doesn’t submit bids or file anything. Preparing and submitting the bid is Carabela’s service — book a demo and we’ll look at your case.
The plugin doesn’t store the text of your searches. For security it logs technical data, such as your IP address, for a limited time. The details are in the plugin’s privacy terms.
For Claude, the free plan is enough: it allows one custom connector. For ChatGPT it depends on your plan and on whether your workspace allows custom MCP servers.
Carabela reads the tender documents, prepares the technical proposal, the administrative envelope and the financial offer, and has it ready to submit.
