Free mini-course: five short steps in your browser

Verify a fake product review or testimonial in 5 stepsthe claim and source, a pause, the reviewer and independent sources, clues, and a dated record

TimeBinder adds a layer of protection against AI and human fraud and disputes. A five-step routine for a product review or testimonial that may be paid, incentivised, copied or machine-written. Progress stays in this browser.

No checker on this page can reliably tell a genuine review from a fake or machine-written one. A TimeBind does not show that a review is genuine. The steps are a routine, not a verdict on any one review.

Start the five steps

Each step is short and ends with one or two checks. Your progress is saved in this browser only. Nothing you choose is sent to TimeBinder. The course uses no real person’s reviews or likeness, only own-made diagrams.

Step 1 of 5. 0 of 5 complete.

Step 1. Name the claim, the review and the source

Three abstract cards labelled Review, Reviewer and Source Review★★★★★ReviewerSource
Own-made diagram: what the review says, who it is said to come from, and where it appeared and who gains from it are three separate things to check.

A review or testimonial arrives with a claim attached: this product works, this seller is honest, this person got these results. Before the stars sway you, write the claim in one line (what is promised, and what you are meant to do about it), and note the source: which platform or page it appeared on, who the reviewer is said to be, and who gains if you believe it. A review is a piece of text, a rating and sometimes photos. It can come from a real customer, from someone who was paid or given a reward, from the seller, or from a tool that writes text on demand. Keep what the review says, who it is said to come from and where it appeared apart.

Check 1. Match each part to what it means

Tap a part, then tap the meaning that fits it best.

Check 2. A product page shows a wall of five-star reviews and “1,200 happy customers”

What is the best first move?

How do you verify a fake-looking product review or testimonial? The short answer

Work through five steps: write down the claim and where the review appeared; pause, because reviews are cheap to produce and pressure like “thousands sold” is a sales tool, not evidence; look beyond the single review at the reviewer’s history, independent sources about the product and what the seller discloses about incentives; weigh clues such as bursts of reviews, repeated phrasing, mismatched products and reused photos as clues only; then decide honestly, say what is unconfirmed, report anything that looks deceptive and keep your notes.

None of this tells you for certain whether a review is genuine, and an online detector score is a clue at most. A TimeBind of an exact file can show that it existed no later than a recorded time and still matches. It does not show that a review is genuine or who wrote it.

Why this course, in November 2026

Search suggestions checked on 13 November 2026 return full lists for “how to spot fake reviews” (including variants for Google, Amazon, Trustpilot, Tripadvisor and eBay), for “fake reviews” (including “fake reviews checker” and “fake reviews examples”) and for “are amazon reviews fake”. Suggestion lists show what people type, not how many type it, and we have not measured volumes beyond that. They do tell us that checking reviews is something people search for. None of this says that a review can be settled by reading it.

This is the eighth course in the series. The first, Spot AI fakes in 5 short lessons, is a general introduction. The second, Verify a viral video in 5 steps, is a workflow for any single clip. The third, Check a suspicious voice message in 5 steps, covers voice messages and calls. The fourth, Verify a screenshot or fake document in 5 steps, is the general screenshot and document course. The fifth, Verify an AI-generated photo of an event in 5 steps, covers event photos, the sixth, Verify a viral news clip in 5 steps, covers clips dressed as news, and the seventh, Verify a leaked-looking chat or email screenshot in 5 steps, covers message screenshots. This one is about reviews and testimonials, where the key move is looking beyond the single review. A ninth course, Verify an AI-generated receipt or invoice in 5 steps, covers AI-generated receipts and invoices, and a tenth, Check a suspicious profile photo or dating profile in 5 steps, covers suspicious profile photos and dating profiles. An eleventh course, Verify an AI-edited rental or property listing photo in 5 steps, covers rental and property listing photos, and a twelfth, Check a suspicious celebrity or expert video ad in 5 steps, covers celebrity and expert video ads. A thirteenth course, Check a photo, video or audio file offered as evidence in 5 steps, covers photo, video or audio files offered as evidence, and a fourteenth, Check a suspicious video call or remote job interview in 5 steps, covers suspicious video calls and remote job interviews. A fifteenth, Check a suspicious website or login page in 5 steps, covers suspicious websites and login pages, and a sixteenth, Check a map or satellite image that may be AI-made or edited in 5 steps, covers maps and satellite images that may be AI-made or edited. All sixteen sit under the public guide to protecting yourself from AI forgeries.

What each step can show, and what it cannot

The honest job of this routine is to slow a snap judgement and leave you with notes you can show. See also synthetic media and existed no later than in the glossary.

Limits of the five steps
StepWhat it can showWhat it cannot show
1. Claim and sourceWhat the review is said to prove, where it appeared, who it is said to come from and who gains.That the review is genuine.
2. PauseWhether urgency or “thousands of happy customers” framing is part of the pattern.Whether a review is genuine or machine-written. Polish proves nothing, and neither does roughness.
3. Beyond the reviewWhether the reviewer’s history looks like one person, what independent sources say, and what the seller discloses.That a review is fake because nothing independent exists, or real because something does. Each is one input.
4. Clues and contextWhat timing, wording, photos, product mismatches and disclosed incentives suggest. Metadata can be edited or lost.Truth or authorship. A “verified purchase” label, missing details or a detector score settles nothing.
5. Decide and keepWhat you checked and found, and that an exact saved file existed no later than a recorded time, with a later copy still matching its SHA-256 fingerprint.That a review is genuine, who wrote it, or that no incentive was involved.

If a review or testimonial may matter later

If a review, a testimonial or a customer’s permission could become part of a dispute, a dated record of the exact files you keep helps:

  1. Save the page or screenshot, the date you saw it and your notes. If you use customer testimonials, keep the customer’s written permission with each one.
  2. Make a TimeBind of the file. The fingerprint is made in your browser and the file stays on your device. You can later download a Proof of Time Certificate.
  3. Store the file, the certificate and your notes together. Use the file date and metadata inspector or the file-changed answer to compare a copy later.

What a TimeBind shows, and what it does not. It shows that an exact file existed no later than a recorded time and that a copy shown later still matches its fingerprint. It does not show who made the file, who owns it, that its contents are true, or whether AI was used to make or edit it. This is general information, not legal advice.

Verify a fake review or testimonial: FAQ

Can this course tell me whether a review or testimonial is real?

No. No checker on this page, and no tool on this site, can reliably tell a genuine review from a fake, paid or machine-written one. The steps help you check the claim, look at the reviewer and independent sources, weigh clues and decide. “Could not confirm, so I did not rely on it” is a valid result.

Can I spot a fake review by how it reads?

Not reliably. Fluent, detailed text can come from a person or a tool, and genuine reviews can be short and clumsy. Bursts of reviews in a few days, repeated phrasing, a review of a different product or reused photos are clues worth noting, not proof.

Does a “verified purchase” label prove a review is honest?

No. It says something narrow about a purchase. Purchases and rewards can be arranged, so the label is a clue, not proof that the reviewer was honest or unpaid.

Can an AI text detector tell me if a review is fake?

No. Detector scores are a clue at most, and they can be wrong in both directions. A genuine review can be flagged and a generated one can pass. Check the reviewer’s history, independent sources and the seller’s disclosures instead.

Does a TimeBind show that a review or testimonial is genuine?

No. A TimeBind shows that an exact file, such as a saved page, a screenshot or a signed customer permission, existed no later than a recorded time and that a later copy still matches its fingerprint. It does not show who wrote a review or that it is genuine.

Should I share a review I cannot confirm?

Better not as fact. If you do mention it, say plainly what is and is not confirmed, and use the platform’s report tools or your consumer regulator for content that looks deceptive. Do not accuse a named person on a hunch.
