This reminds me of a funny experience at work
They linked some internal llm with all the confluence documentation sets
My product owner tried to find information about our product, as a regular user would, so feel the experience from a user's perspective
It was a failure: only random, generic answers were received
Then, he retried, specifically citing our main confluence pages: it was a success
Conclusion: for the users that already know were is the documentation, the tool is helpful. Reading the page would be also helpful.
Conclusion (reworded): if you know where is the treasure, then the magic gold-detector will work;
