Plan & Act mode overview
The Plan & Act mode is an upgraded agentic mode in CustomGPT.ai. It adds a planning brain, code execution, and additional actions to what regular agents can do. Some of these capabilities are exclusive to it. All enabled actions can run together in a single response.
How it works
Every message first goes to a planning brain. It reads the request, decides what steps are needed, and works through them in sequence - searching the knowledge base, running a calculation, calling an outside service, or combining all three in a single response. The user sees each step in real time.
If the agent hits a dead end or needs something it does not have - a file, a clarification - it stops and asks the user for input. If the user changes direction mid-conversation, the agent updates its approach without starting over.
Your persona and guardrails stay in control throughout. The planning brain works within the rules you set as a builder - it cannot override them.
