An AI tool is useful when it helps you complete a task you can still check. Start with the task, the information you are allowed to share and the output you need. Free access, limits and features can change, so verify the current plan before relying on a particular service.
Pick a workflow before a product
General assistants such as ChatGPT, Gemini and Copilot can be starting points to investigate. This guide does not rank their current models or promise a particular free feature. Check the provider’s current documentation for supported inputs, account requirements, usage limits and data controls.
| Task | Useful request | Check before using the result |
|---|---|---|
| Study revision | Ask for questions based only on notes you supply | Confirm answers against the notes or textbook |
| Writing | Ask for clearer structure while preserving supplied facts | Check that meaning, tone and commitments have not changed |
| Spreadsheet practice | Ask for a formula using a small synthetic example | Test it manually on ordinary and unusual inputs |
| Interview practice | Ask for one question and feedback at a time | Keep examples truthful and specific to your experience |
A study prompt you can adapt
Using only the notes below, ask me five short questions one at a time. After each answer, explain what I missed and point to the relevant part of the notes. If the notes do not contain enough information, say so instead of filling the gap.
This instruction can help define the task, but it does not guarantee faithful answers. Check the references the tool gives. Follow your institution’s rules for assignments, examinations and disclosure.
A work-writing prompt
Rewrite the draft below as a concise handover note. Use the headings Completed, Pending and Questions. Preserve every supplied date and amount. Do not add deadlines, commitments or claims.
Compare the result with the source before sending it. In particular, check names, dates, figures and whether an uncertain statement became a confident one.
Run a small trial
Try one task with non-sensitive material. Keep the original, the generated result and your corrections. Count checking time as part of the task. If the result needs extensive repair, change the request or choose a different workflow rather than assuming more fluent wording means better accuracy.
Protect information and ownership
Do not upload passwords, private medical records, confidential company documents or other people’s personal information without appropriate permission and handling arrangements. Review the service’s current data controls. Use material you are permitted to share and check rights before publishing generated or edited assets.
When to stop using the output
If a tool cannot support a factual claim, return to the original source. For medical, legal, financial or other consequential decisions, generated text is not a substitute for suitable professional advice or authoritative information. A polished answer can still be wrong.
