Why checking AI output is not optional

A 2026 survey found that 66% of workers spend six or more hours a week correcting AI mistakes. The problem isn't usually obvious errors — it's subtle ones that pass a quick read. The AI gets a figure slightly wrong. It attributes something to the wrong person. It uses a phrase that's technically accurate but implies something you didn't intend. It confidently states something that isn't true.

AI-generated text is also designed to read smoothly. The better the output looks, the more likely you are to send it without reading it carefully. That's exactly when mistakes get through.

The good news is that reviewing AI output well doesn't take long — it takes about 3–5 minutes for a typical work document, with the right process.

The five things to check in every AI output

1. Factual claims you can verify

Any specific figure, date, name, or factual statement the AI produced that you didn't give it should be treated as unverified until you check it. The AI may have produced it from training data that's outdated, approximate, or simply wrong. If a claim matters — if someone might rely on it or challenge it — verify it from a primary source.

2. Assumptions it made about context

If your prompt was vague, the AI filled in gaps with assumptions. Check whether those assumptions are correct. Common ones: it assumed the wrong audience, gave the wrong level of detail, or framed the situation in a way that doesn't match reality.

3. Filler phrases and generic language

Well-written AI output still tends to include phrases like "it is important to note that", "in today's fast-paced environment", "going forward", and "it goes without saying". These add length without meaning. Cut them.

4. Claims that sound specific but aren't

Watch for numbers that look precise but weren't in your source material. If you didn't provide a figure and the AI produced one, check it. AI tools occasionally invent plausible-looking statistics that don't exist.

5. Tone and attribution

Does it sound like you (or like your organisation)? Does it make any claims on behalf of your company that go further than you intended? Does it attribute positions, quotes, or decisions to named people — and if so, are those attributions correct?

The review prompt you can use right now

Instead of running through this checklist manually, you can ask the AI to do a first pass for you. Paste this into a new chat with the output you want to review:

Review the following AI-generated text and flag any issues. Check for: 1. Specific claims (figures, dates, names, statistics) that weren't in my original prompt — mark each one with [VERIFY] 2. Filler phrases or sentences that add no meaning — mark with [CUT] 3. Language that sounds generic and could apply to any company or situation — mark with [GENERIC] 4. Anything that implies a position or decision that wasn't stated in the brief — mark with [CHECK INTENT] 5. Tone issues — anything that sounds too formal, too casual, too vague, or out of character for a professional workplace communication After flagging, give me a brief summary: how many issues, and which category has the most problems.

What to do with the flagged output

Once you've run the review prompt, go through each flag. [VERIFY] items: check them against the actual source — an email, a report, a contract, whatever you were working from. [CUT] and [GENERIC] items: delete them. They make the output weaker, not stronger. [CHECK INTENT] items: read the original brief and decide whether the AI interpreted it correctly.

This whole process takes about 3 minutes for a typical email and 5–8 minutes for a longer document. The alternative — sending it without checking and dealing with a correction or a follow-up — takes longer and damages credibility.

A note on what the AI can't check for you

The review prompt above is useful, but it doesn't replace your judgment on two things. First: is the advice or recommendation correct for your specific situation? The AI doesn't know your organisation's history, your specific client relationship, or the full context behind a decision. Second: does this output match what you actually wanted to say? Read it from the recipient's point of view. If there's any ambiguity about what you mean, clarify it before sending.

💡 This week's action

Save the review prompt above somewhere you can paste it quickly — a notes app, a text file, a saved ChatGPT prompt. Use it on the next piece of AI-generated content you're about to send. Notice whether it catches anything you would have missed on a quick read.
