Ask HN: How to keep track of answers from several AI systems?

At this time I have several preferred interactive GUI-based AI systems: ChatGPT, Perplexity and others.

Often I have an open question and say, ChatGPT answers it quite thoroughly. Still, sometimes I ask the same question to a second system and I get answers with different aspects that ChatGPT did not include in its answer. I do this for comparison, for informal benchmarking.

So I want to merge the two answers together. But how can I do that?

How do _you_ do that?

- With a notetaking software?

- Simply appending interesting text passages from system 2 into the chat window of system 1, hitting the "Stop Generating" button?

- Using a specialized service, or a browser plugin?

Asking for software recommendations but also for best practices.
