A small-business owner tracked every task an AI agent did for 30 days: 80 hours saved
In plain words
For 30 days the owner logged every task the agent handled, how long it would have taken, and the time lost to its mistakes.
What happened: 382 tasks done and 79.6 hours saved, after 2.3 hours lost to mistakes (their own figures).
These numbers come from the builder and haven't been checked independently.

- 2
Give the agent one task type at a time.
- 3
Log every task for 30 days, including mistakes.
- 4
Drop tasks where review takes as long as doing it.
- 5
Keep the ones with the best time saved.
The instructions to give the AI
Paste this into ChatGPT (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.
Agent instructions (prompt)
Here is my task log for this week: [paste rows]. Total the time saved, list the 3 task types with the best savings and the 2 with the most errors, and suggest one task to stop giving the agent.
[Highlighted] = replace with your own details before you run it.
What you should get back: "Saved 19.5 hours. Best: email replies, meeting notes, invoice chasing. Most errors: calendar moves. Stop: social replies."
