My starting point
I started with AI through ChatGPT in November 2022, as soon as the conversational version came out.
What it does well
- Fast answers on a large number of subjects, with features around text: files, images, voice, memory, scheduled tasks depending on the plan (official plans page).
- A script skeleton or a command from a clear description.
- Rewrite, summarize, translate a procedure or a message.
Where I stay wary
- It answers with confidence even when it makes things up: a command option that does not exist, an imaginary module parameter. Check the vendor’s documentation.
- The offer changes often: names, tiers and limits move. A screenshot of a price goes stale within weeks.
- The official page says the Go plan “may include ads”.
IT use cases
| Need | What I ask it | What I check |
|---|---|---|
| PowerShell script | “List mailboxes last accessed more than 90 days ago, as CSV” | Cmdlets and parameters on Microsoft Learn, -WhatIf |
| Troubleshooting | “Here is an error (anonymized); which causes, in what order to test?” | Each lead on the machine, not on trust |
| Documentation | “Turn these notes into a numbered procedure” | That nothing was added or dropped |
| Reading logs | “Summarize this excerpt (addresses replaced)” | The original excerpt |
Privacy and GDPR
- Do not paste secrets, clients’ personal data, message contents or internal diagrams into a consumer plan.
- Anonymize before pasting (
client-A,192.0.2.10,example.com). - For professional use, look at the Business or Enterprise plan: the official page lists per-user plans starting at 2 users. Read the terms on data use before deciding.
- Check in your account settings what applies to history and to model improvement.
