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

Speechify

Documents you listen to are uploaded to the service's servers: keep contracts and HR documents with personal data out
The voice reads abbreviations and numbers oddly: for reports with figures, listen along with the text
The trial converts to annual billing automatically: cancel before it ends if the service does not suit you
