Second Source

Terms of service

Last updated November 13, 2026

These terms are the agreement between you and LookN9, Inc., 131 Continental Drive, Suite 305, Newark, Delaware 19713, United States (“we”, “us”), which runs Second Source. By using Second Source or creating an account, you accept them. Our privacy policy explains how we handle personal data.

What Second Source is

Second Source checks posts from X, news articles and claims, reviews the public accounts behind them, and reports on how stories spread. It uses AI to research each claim against the sources it can find, and gives a verdict with the sources behind it. How we decide explains the method.

Second Source is an independent service, not affiliated with or endorsed by X Corp.

What results are, and aren't

  • A result is our assessment, based on the sources we found when the check ran. It can be wrong, incomplete or overtaken by later events. Check the sources before you rely on it.
  • A rating of an account reflects the sample of its public posts we checked. It isn't a judgement of the person or organisation behind it.
  • Results aren't legal, financial, medical or other professional advice. You're responsible for the decisions you make with them.
  • If you think a result is wrong, use the “Dispute” tab on its page. A person reviews every dispute, and if we uphold it the result is withdrawn for everyone.

Your account

  • You must be at least 16 to use Second Source, and old enough to make a binding contract where you live to buy a plan or credits.
  • Give us accurate details, keep your password safe and tell us straight away if you think someone else is using your account. Accounts are for one person and can't be shared or sold.
  • If you sign in with X, X's own terms also apply to your X account. You can disconnect Second Source from X at any time in X's settings.

Using Second Source fairly

You agree not to:

  • use Second Source for anything unlawful, or to harass, threaten, expose or target anyone;
  • use it to build profiles of private individuals;
  • alter a result and present it as ours, or present a result as saying something it doesn't, or suggest that we endorse you or your content;
  • copy results or data in bulk, or reach Second Source with scripts, bots or scrapers, other than through tools we provide for that, such as batch checks;
  • get around credits, plan limits, locked results or security measures, probe or disrupt our systems, or try to work out how Second Source reaches its results by reverse engineering it;
  • resell or give others access to Second Source or its results as part of your own service.

What you submit, and what we make

  • You keep any rights you have in what you submit: links, text, notes and source lists. You allow us to use it to run Second Source, including to research it with the providers that work for us. Only submit what you're allowed to.
  • Results of standard checks are shared: anyone with the link sees the verdict and headline, and other readers can unlock the full result. Deep checks, notes and source lists stay private to you.
  • Second Source, its results, ratings and reports belong to us. You may share links to them, and quote a verdict and its headline with a link back. Pro readers may use the dossiers they export in their own work and publications, crediting Second Source. Anything else, such as republishing full results or reusing them in bulk, needs our written permission.
  • Posts we show belong to their authors and are shown under X's rules. Sources we link to belong to their publishers, and we aren't responsible for them.

Plans, credits and payment

  • Credits. Checks, account reviews, reports and unlocking someone else's result cost credits. The pricing page shows what each costs. A run that fails through our fault costs nothing.
  • Plans. Each plan gives you credits every month. They're replaced when the next month's arrive, so unused plan credits don't carry over. Paid plans are billed monthly in advance and renew automatically until you cancel.
  • Who sells it. Plans and credits are sold to you through Link, the merchant of record service of Stripe, our payment provider. Link takes the payment, collects any tax that applies, sends your receipts and invoices, and answers questions about payments, and your bank statement shows the payment as made to Link.
  • Cancelling. Cancel any time from your account page, or from your Link account. You keep your plan until the end of the month you've paid for, and it isn't renewed.
  • Bought credits never expire while your account is open. Credits have no cash value and can't be transferred.
  • Running below zero. A run can cost more than you have left. Your balance then goes below zero, the result stays locked until it's back above zero, and the next credits you get pay off the difference first.
  • Prices can change. A new price for a plan applies from your next renewal after we tell you about it. Any tax that applies is shown at checkout, before you pay. Depending on the currency you pay in, it's added to the price or already included in it.
  • Refunds. Payments aren't refundable except where the law requires it or these terms say so. If you're a consumer with a legal right to cancel a purchase within a set period, you ask us to start providing the service as soon as you pay, and you lose that right for credits once you've used them. Link may also refund a payment in some cases, for example to settle a dispute about it.

Changes, suspension and closing your account

  • We may change, add or remove features. If we remove something you've paid for, we'll offer a fair alternative or a refund for the part you can no longer use.
  • You can stop using Second Source at any time, and delete your account from your account page, or ask us to by writing to [email protected]. Deleting it ends any subscription straight away, without a refund for the rest of the month, and any credits left are lost.
  • We may suspend or close an account that breaks these terms, telling you why where we reasonably can. If we close your account without you having broken them, or stop running Second Source, we'll refund any bought credits you haven't used.

Our responsibility

We work to keep Second Source accurate and available, but we provide it as it is, without promising that it will always be available, error-free or right. As far as the law allows, we aren't responsible for losses that weren't foreseeable, for decisions you or others make based on a result, or for losses over the amount you paid us in the 12 months before the claim. Nothing in these terms limits responsibility that the law doesn't allow us to limit, or takes away rights you have as a consumer.

Changes to these terms

We may update these terms. We'll post the new version here and update the date at the top, and tell you on the site before significant changes take effect. If you don't agree with them, you can stop using Second Source and cancel your plan before they apply.

Law and disputes

These terms are governed by the law of the State of Delaware. If we disagree, please write to us first and we'll try to settle it. Otherwise the courts of the State of Delaware will decide, but if you're a consumer you keep the protection of the laws of the country where you live, and can bring a claim there.
