Pitfalls to watch at work

Mem

Notes are stored in the service's cloud: keep passwords and employee personal data out
An answer from your notes also pulls in outdated entries: look at the date of the note it cites
Test the note export before moving your whole base there, so you have a way back

Perplexity

The links are there, but the model sometimes retells what is behind them inaccurately: open the source and find the claim word for word
For official registers (company, court, tax) the engine gives only a surface picture: check critical facts in the register itself
On the free plan, turn off AI Data Retention in settings, otherwise queries with client names may be used for training
