Define the input and output: documents, notes, email, calendar events, browser pages, summaries, presentations, databases, or action items.
Check whether the tool runs where your work already happens and connects to the apps you rely on.
Decide how much autonomy you want and whether automated actions can be reviewed, edited, or undone.
Review source boundaries, data handling, privacy controls, integrations, exports, and plan terms.
Test one representative workflow, record the review effort and failure modes, and keep a rollback path before expanding.
