The deal.

Effective May 18, 2026.

These Terms of Service ("Terms") form a binding agreement between you and Thalient Labs, LLC, a Delaware limited liability company ("Knack", "we", "us"). They cover your use of the Knack website, web app, CLI, API, and anything else we ship under the "Knack" name (collectively, the "Service"). By creating an account or using the Service you agree to these Terms. If you don't agree, don't use the Service.

We've kept the language plain. It is still a contract. The bold-text callouts inside each section are the parts most likely to matter to you.

What Knack does

Knack is a tool for turning a recurring task you do at work into a versioned, runnable AI skill in the open Anthropic Skills format. You teach it through an interview; you get back a Skill folder you (or any agent you authorize) can run. We host the Skill store, conduct the interview, and run the model calls that generate the Skill. We do not execute the Skill against your private systems. That happens locally, on your machine, inside the agent you choose.

Accounts and eligibility

You must be at least 18 years old to use Knack. Knack is not for children. By signing up you represent that you are 18 or older, that the information you give us at registration is accurate, and that you are authorized to bind any organization on whose behalf you are signing up.

You are responsible for everything that happens under your account. Keep your sign-in credentials safe. Notify us at support@getknack.ai if you suspect unauthorized access. We use Clerk for authentication and billing; their terms apply alongside ours where they're inside their flows.

Your content; what you keep

Everything you create using the Service is yours. The interview transcript, the captured rules, the SKILL.md file and assets, any artifacts you uploaded — your content, your copyrights.

Personal-scope Skills are visible only to you.
Team-scope Skills are visible to members of the Team you've shared them with.
Public-scope Skills published to the marketplace are visible to everyone with a Knack account, and may be discoverable via search engines.

You can un-publish or delete a Skill at any time. Deletion is described in the Privacy Policy.

License you grant to us

To operate the Service, we need a license to handle your content. You grant Knack a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, display, process, and run your content solely as required to provide and improve the Service for you. This license ends when you delete the content or close your account, except for backups retained as described in the Privacy Policy.

We do not claim authorship of your Skills. We do not use your private (Personal- or Team-scope) Skills to train our models or third-party models. See Privacy for the full data-use story.

Marketplace publication and Skill licensing

When you publish a Skill to the public marketplace, you are making it available to everyone. You confirm you have the right to publish it. By publishing a Skill publicly you license that Skill to other Knack users (and the general public) under the Apache License, Version 2.0 (apache.org/licenses/LICENSE-2.0) unless we expressly offer and you select a different license at publication. This means other users may copy, modify, fork, and redistribute your published Skill subject to the Apache 2.0 attribution and notice requirements.

You can un-publish a Skill at any time. Un-publishing prevents future downloads from the marketplace, but it cannot pull back copies that others have already obtained under the license you granted, and it does not affect that license for those copies.

Public Skills may be used by us in benchmarks, evaluations, demonstrations, examples, and (where useful) in training data for our or our subprocessors' models. Private (Personal- and Team-scope) Skills are excluded from those uses.

Acceptable use

Don't use Knack to do or build things that are illegal, harmful, or that violate other people's rights. Without limiting the foregoing, you agree not to:

use the Service to engage in or facilitate illegal activity, harassment, threats, doxing, stalking, or discrimination;
generate, store, or distribute child sexual abuse material, content that exploits minors, or non-consensual intimate imagery;
create malware, spyware, ransomware, phishing tooling, or any code designed to compromise systems or steal credentials;
infringe intellectual-property rights, misappropriate trade secrets, or violate confidentiality or non-disclosure obligations;
attempt to overload, disrupt, or circumvent the Service, its rate limits, its access controls, or our subprocessors' systems;
scrape, probe, or extract data you do not have permission to access, including other users' Skills or training data;
resell or rebrand the Service without our written authorization;
use the Service in any way that would cause us to violate sanctions, export controls, or other applicable law.

We may suspend or terminate accounts that breach these rules. Some uses (CSAM, credible threats of violence, exfiltration attempts) result in immediate termination and may be reported to law enforcement.

AI output disclaimer

Skills generate AI output. The output may be wrong, misleading, biased, incomplete, or fabricated. You are responsible for reviewing what a Skill produces before relying on it for anything that matters — money, law, medicine, hiring, safety, anything. The Service is not a substitute for professional judgment.

Authorship of a Skill rests with the user who created it. Execution of a Skill happens inside the agent you choose to run it in (Claude, Cursor, Codex, or another agent). Knack does not warrant the accuracy of any Skill (yours or anyone else's), the safety of any agent vendor's runtime, or the outputs produced by an agent running a Skill. Responsibility for what a Skill does when run lies with the Skill's author and the agent vendor running it, not Knack.

Plans, billing, refunds

Free plans are available subject to the limits posted on the pricing page. Paid plans renew automatically each billing period until cancelled. Pricing in effect when you start a billing period applies to that period.

Cancel any time. Cancellation stops the next renewal; we do not pro-rate or refund partial periods. Your paid access continues until the end of the period you've already paid for. We may, at our discretion, issue a refund or credit for a billing error.

Billing, currency conversion, payment processing, and applicable taxes are handled by Clerk and its payment partners. We rely on those partners' tax determinations. If you believe tax was charged incorrectly, contact us and we'll work with the processor to resolve it.

Changes to the Service

We add, change, retire, and reprice features. We may also change these Terms. For changes that materially reduce your rights or our obligations to you, we will give at least 30 days' notice by email and by posting an updated version with a new "Effective" date. Your continued use of the Service after the new Terms take effect means you accept them. If you don't accept, stop using the Service and cancel your subscription before the new Terms take effect.

We may also change pricing for a future renewal period with at least 30 days' email notice. Price changes don't apply retroactively to a period you've already paid for.

Suspension and termination

You may terminate your account at any time by deleting it from your account settings or by emailing support@getknack.ai. Your data is handled per the Privacy Policy on deletion.

We may suspend or terminate your account for (a) clear abuse of the Service, or (b) non-payment of fees, including chargebacks, payment-method failures, or fraudulent payment activity. We will provide reasonable notice and an opportunity to cure where the breach is curable; we may act immediately where the breach is egregious or where the law requires.

On termination, your right to use the Service ends. Provisions that by their nature should survive (license grants for publicly-published Skills, disclaimers, limits, indemnity, dispute resolution) survive termination.

Disclaimer of warranties

The Service and all content are provided "AS IS" and "AS AVAILABLE", without warranty of any kind, express or implied. To the maximum extent permitted by law, we disclaim all warranties including merchantability, fitness for a particular purpose, non-infringement, accuracy, uninterrupted access, and freedom from errors or harmful components. We do not warrant that the Service will be secure, error-free, available at any particular time, or that AI output will be accurate, reliable, or fit for your use.

Some jurisdictions don't allow disclaimers of certain warranties. In those jurisdictions, the disclaimer applies to the maximum extent permitted by law and any non-disclaimable warranty is limited to the shortest period and lowest scope permitted by law.

Limitation of liability

To the maximum extent permitted by law, Knack and its officers, employees, contractors, and agents will not be liable for indirect, incidental, special, consequential, punitive, or exemplary damages, or for loss of profits, revenues, data, goodwill, or business opportunity, arising out of or related to the Service, even if we have been advised of the possibility of such damages.

Our total liability to you, in the aggregate, for all claims arising out of or related to the Service or these Terms is capped at the greater of (a) USD $100 or (b) the fees you actually paid us in the twelve (12) months immediately preceding the event giving rise to liability. This cap applies whether the claim is in contract, tort, statute, or any other theory.

Some jurisdictions don't allow these limits. In those jurisdictions our liability is limited to the maximum extent permitted by law.

Indemnity

You agree to defend, indemnify, and hold harmless Knack and its officers, employees, contractors, and agents from any claim, demand, loss, liability, damage, cost, or expense (including reasonable attorneys' fees) arising out of (a) your use of the Service, (b) your content, including Skills you publish to the marketplace, (c) your breach of these Terms or applicable law, or (d) your infringement of any third party's intellectual-property, privacy, publicity, or contractual rights.

We reserve the right to assume the exclusive defense and control of any matter for which you owe us indemnification, in which case you'll cooperate with us in asserting available defenses.

Governing law

These Terms and any dispute arising out of or related to them or the Service are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Binding arbitration and class-action waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS HOW DISPUTES ARE RESOLVED.

You and Knack agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service (other than the carve-outs below) will be resolved by final and binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules (or, if you are a commercial user, its Commercial Arbitration Rules). The arbitration will be conducted by a single arbitrator in Wilmington, Delaware, in English, with limited document exchange and no in-person hearings unless the arbitrator finds them necessary. Judgment on the award may be entered in any court of competent jurisdiction.

CLASS-ACTION WAIVER. You and Knack each waive any right to bring or participate in a class action, collective action, or consolidated proceeding. All claims must be brought individually. If a court holds the class-action waiver unenforceable as to a particular claim, that claim (and only that claim) will be severed and may proceed in court; the rest of this section continues to apply.

Carve-outs. Either party may (a) bring an individual claim in small-claims court if it qualifies, or (b) seek injunctive or equitable relief in court to protect intellectual-property rights, confidential information, or against unauthorized use of the Service. These carve-outs do not waive arbitration for any other claim.

Opt-out. You may opt out of this arbitration agreement by emailing support@getknack.ai within 30 days of first accepting these Terms, with the subject line "Arbitration Opt-Out" and your full name and account email. Opting out does not affect any other part of these Terms.

To the extent any dispute is not subject to arbitration, you and Knack consent to the exclusive jurisdiction of, and venue in, the state and federal courts located in New Castle County, Delaware, and waive any objection to personal jurisdiction, venue, or forum.

Notices

We send legal notices to the email address on your account; please keep it current. You send legal notices to us at:

Thalient Labs, LLC c/o Legalinc Corporate Services Inc. 131 Continental Dr, Suite 305 Newark, DE 19713, USA email: support@getknack.ai

Miscellaneous

These Terms, together with the Privacy Policy and Subprocessors page, are the entire agreement between you and Knack about the Service and supersede prior agreements on the subject. If any part is held unenforceable, the rest stays in effect. Our failure to enforce a provision is not a waiver of our right to enforce it later. You may not assign or transfer your rights under these Terms without our written consent; we may assign these Terms to an affiliate or in connection with a merger, acquisition, or sale of assets. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and us.
