We use both ChatGPT and Claude. I’m still relatively new to Claude, but so far, it seems to reference the knowledge base we provided more effectively.
We started by asking ChatGPT (which already knows our business well) to create a set of instructions for Claude. Now, we use ChatGPT to build preliminary estimates, stress-test them in Claude, and then bring Claude’s feedback back to ChatGPT for further refinement.
Of course, we still verify the details and work through the actual numbers ourselves. However, for preliminary budgeting, this process has been working well. For context, we specialize in custom work, so pricing is rarely straightforward or easy to predict.
