1. Agreement
These terms are between you and Convincer. Using the site means accepting them. If you are agreeing on behalf of a company, you are confirming you may bind it.
2. What Convincer is
Convincer ranks products within a category. Positions are taken by filing a case against the product directly above and convincing a panel of AI jurors, each of which scores both sides against a published rubric and publishes its reasoning.
Rank cannot be bought. Paid credits buy the ability to file — a place in the queue — and never a favourable outcome. Nothing you pay for changes how a juror scores. If that ever stops being true, the service has no reason to exist.
3. Rankings are opinion, not fact
This section matters more than the rest of this document.
Every verdict on this site is an evaluative opinion produced by language models applying a published rubric to material both sides submitted. Verdicts are not statements of objective fact about any product, not a certification, not an audit, and not professional advice. Reasonable people — and other models — could read the same filings and reach a different conclusion.
Each verdict is published with the evidence it rested on, the reasoning of each juror, any dissent, and the panel selection seed, so that anybody can check the basis for it and disagree with it specifically. Language models are wrong sometimes. Read the reasoning, not just the position.
Do not make a purchasing decision on rank alone. The site tells you what was argued and what was shown; it cannot tell you whether a product suits you.
4. Listings and who may create them
Anyone with an account can list a product, including one they do not own. A listing therefore does not imply the vendor took part, endorsed anything, or is even aware of it. Where a product was listed by somebody other than its vendor, that is not a statement by the vendor.
If a product of yours is listed and you want to control the listing or have it removed, write to legal@convincer.site from an address at the product’s own domain. Control of the listing will be transferred to you, or the listing removed, at your choice.
Trials already decided are not deleted on request — see §9.
5. Accounts
Sign-in is by emailed link. Anyone who can read your email can sign in as you, so the security of your account is the security of your inbox.
One account per person or company. Creating multiple accounts to file against yourself, to manufacture wins, or to evade a cooldown is grounds for removing the accounts and the ranks won through them.
6. What you file
You keep ownership of what you write. By filing it you grant a non-exclusive, worldwide, royalty-free licence to publish, display, and archive it as part of the trial record, including after your account is closed. Without that, a losing party could erase the evidence behind a ranking that another party won.
When you file, you are stating that:
- The claims are true to the best of your knowledge and the evidence is what you say it is.
- Comparative claims about a competitor are accurate and you can support them.
- You have the right to publish everything in the filing.
- Nothing in it is designed to manipulate the jury rather than persuade it.
You are responsible for your filings. A claim about a competitor is your claim, published by you, and you agree to cover the costs if it causes a third-party claim against the operator.
7. Right of reply
Before any trial is decided, the defending product’s account is notified and has 48 hours to answer. A silent defender gets a defence auto-generated from its own dossier, marked as such — never as strong as one they would have written.
If a product of yours is judged and you were not reachable, write to legal@convincer.site. A published reply will be attached to the trial.
8. Things you may not do
- Fabricate evidence, or cite a source that does not say what you claim it says.
- Attempt to instruct, manipulate, or prompt-inject a juror. This is detected at intake, rejected, costs standing, and is shown to the panel as evidence of bad faith.
- Register accounts you control in order to lose to yourself on purpose.
- Scrape the site in a way that degrades it for others.
- Use the service to harass a competitor rather than to argue against a product.
Standing is reduced for bad-faith filings and is public. Serious or repeated abuse ends the account.
9. Corrections and removals
If something published about your product is factually wrong, write to legal@convincer.site saying which specific claim is wrong and why. Claims that cannot be supported are removed, and a correction is published on the trial page.
A verdict you merely disagree with is not removed. It stays, with its evidence and its reasoning visible, and you are free to file again — that is the mechanism the site provides for being wrong about you.
10. Payments
Credits are bought through Stripe. Prices are shown before purchase. Credits do not expire.
Stripe runs the checkout and holds the card details — they are entered on Stripe’s own page and never reach this server, so what Stripe does with them is governed by Stripe’s privacy policy. Everything else about the sale is handled here: issuing the credit, deciding a refund, and running the service the credit is for.
An unused credit is refundable within 14 days. A credit spent on a filing that has been judged is not, because the cost was incurred: a panel ran. If a trial fails for a technical reason on this side, the credit is returned automatically.
Refund requests go to support@convincer.site.
Consumers in the UK and EU keep their statutory rights, including the statutory cancellation right, which these terms do not limit.
11. Availability
The service is provided as it is, without warranty of any kind. There is no uptime guarantee. Trials may be delayed by capacity at the model provider, and features may change or be withdrawn.
12. Liability
To the extent the law allows, the operator is not liable for indirect or consequential loss, lost profit, lost business, or any decision made on the basis of a ranking. Total liability for any claim is limited to what you paid in the 12 months before it arose.
Nothing here excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded. Consumer statutory rights are unaffected.
13. Ending it
You may close your account at any time. The operator may suspend or close an account that breaches these terms. Decided trials remain published, detached from the closed account.
14. Governing law
These terms are governed by the law of the place Convincer is operated from, and disputes go to its courts.
If you are a consumer, that does not deprive you of the protection of the mandatory law where you live, or of your right to bring a claim there. Write to legal@convincer.site before starting one — most disagreements about a verdict are cheaper to fix by publishing a correction.
15. Changes
These terms may change. Material changes are emailed to account holders before taking effect, and the date at the top always reflects the current version.
