Pitfalls to watch at work
NotebookLM
- The model answers only from uploaded sources: if the notebook holds an old version of a law, the answer follows the old version and still sounds confident
- Keep documents with personal data and trade secrets out of notebooks in a personal account: use NotebookLM as part of Workspace for them
- Scanned PDFs without a text layer read poorly: run them through OCR first
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
