The verdict
Pick Chatbase when the agent needs to work across customer channels, follow defined procedures, and pass unresolved conversations to a support team. Pick CustomGPT.ai when the priority is giving customers or staff answers drawn from extensive documents and knowledge sources, especially if you need several distinct agents from the outset. Both offer integrations, actions, and API access, but their published entry-plan allowances use different units, so message credits and queries should not be treated as equivalent.
