+1 on connectors over migration. also check how it handles conflicts when two connected sources disagree — that's where "integration" usually gets messy.
Big one is avoiding the re-silo trap. If the tool makes you copy everything in, you've just created a 6th place to go stale. Look for connectors to your actual sources.
Inventive AI does this well — it connects to your existing sources (docs, wiki, help center, past responses) and organizes them into a context graph instead of making you migrate. The graph is what lets it figure out which source a given question should be answered from, so integration isn't just ingestion, it's routing to the right hub. That was the difference for us.
"integration isn't just ingestion" is a good way to put it, thanks
