Keep facts separate from inference

Start with this example

Source A, dated Monday: “The beta has 20 participants.”
Source B, dated Friday: “The beta has 35 participants.”
Neither source states revenue or whether participants pay.

Give your assistant a clear brief

Use a compatible tool you already have, or choose a reviewed guide below. This is a suggested learning exercise, not proof that a specific installation has been tested.

Using only these two sample sources, write three sentences on the beta. Identify what changed and cite A or B for every factual statement. State what cannot be concluded about revenue.

A (Monday): The beta has 20 participants.
B (Friday): The beta has 35 participants.

Check the result

The latest count is 35, the increase is 15 and revenue is unknown. Participants are not automatically paying customers. Any revenue estimate is unsupported.
