No additional purchase is required to access the AI tools themselves – they are included with Carveco subscription products (Maker, Maker Plus, and Carveco Pro). However, using the AI tools does require credits, an allowance of which are provided as part of your subscription. But additional credits can also be purchased separately if you need more, either in one-off packs or as a monthly or annual credit subscription. These additional credits can be purchased through your Carveco Account.
