Terms of Service
Last updated 14 October 2026
These terms are an agreement between you and Prompier LLP ("Prompier", "we", "us") about your use of the Prompier website, web app and browser extension (the "Service"). By creating an account or using the Service you agree to them. If you use Prompier for an organization, you confirm you can accept these terms for it.
1. Your account
- You must give accurate details, keep your password safe, and tell us if you think someone else has used your account. You are responsible for what happens under it.
- You must be at least 16 years old, or the age of digital consent where you live if that is higher.
- One person per login. Team workspaces use seats, and each member needs their own (people who only run apps shared with them, as App users, do not need one).
2. Your content
Prompts, snippets, comments and anything else you put into Prompier is "your content". You own it. You give us permission to store it, process it and show it to the people you choose (for example your team) only so we can run the Service for you. We do not use your private content to train AI models, and this will stay true for any AI feature we add later unless you separately and clearly opt in. We do not read your private content except when you ask us to help with a problem, when we must to keep the Service safe or obey the law, or, for prompts you choose to submit to the community library, when volunteer moderators review the submission and any report about it. Our staff can reach private content only as far as needed for those purposes.
Do not put anything in Prompier you have no right to store, and avoid storing personal data about other people or secrets such as passwords and API keys in prompts.
Testing with your own AI key. If you add an API key from an AI provider, you do so at your own risk and cost: you remain responsible for the key, for the charges your provider makes, and for following your provider's terms. When you run a test, the prompt text is sent to that provider. The provider is not our subcontractor for this: it handles the text under its own terms and privacy policy and your agreement with it, and we are not responsible for what it does with the text or for its answers. We show cost estimates, but they are only estimates, and we are not responsible for charges you incur. Do not add a key you are not allowed to use. Do not test prompts that contain information you are not allowed to send to that provider.
Apps and their results. Apps send the text you type and the text of the prompts they use to an AI provider, using a key you added or, in a team, the team's own key. Results are saved with your runs, can be sent to members of your workspace and shared with the team by you, and can be read through the API by keys your team creates with the results scope. You are responsible for what you put into an app and for checking its output before you rely on it. Results are produced by AI and may be wrong. A team key spends the team's money: owners and admins set spending limits and are responsible for them, and the figures we show are estimates from list prices, not a bill.
In a team workspace, an owner or admin decides whether members may test or run apps. By turning testing on, they decide for the whole workspace that members may send prompt text to third-party AI providers, and they are responsible for making sure that fits the team's own data rules and its agreements with its customers.
3. Community library
- Submitting a prompt is optional. If you submit one and it is published, you license it to everyone under the license you chose on the submission form: CC BY 4.0 (anyone may reuse and adapt it if they credit you), CC0 (you give up your rights as far as the law allows, no credit needed) or MIT (anyone may reuse and adapt it if they keep your copyright notice). Choose carefully: that license is irrevocable for copies people have already made, even if you later withdraw the prompt, and CC0 cannot be taken back.
- Separately from that public license, when you submit a prompt you give us a worldwide, non-exclusive, royalty-free license to store, display, format, translate for display, feature and promote it inside the Service and the community library, and to keep a record of the submission and its review. This license ends when the prompt is removed from the library, except for backups and records we must keep, and except for copies people have already made under the public license.
- You confirm you wrote the prompt or have the right to share it, and that it contains no personal data (yours or anyone else's), secrets or content that breaks the law or the community guidelines. Remove other people's names, contact details and customer or employer information before you submit.
- If you delete your account, published prompts stay available under their license but without your name.
- If you think something in the library infringes your rights, see our copyright and takedown page.
- Moderators are volunteers. They may decline, hide or remove submissions, and we may do so too. Their decisions are not legal advice and we do not guarantee that published prompts are accurate or safe for your use.
- Prompts in the community library are provided "as is". Check the output of any AI tool before you rely on it.
4. Acceptable use
Do not use the Service to break the law, harass or harm others, send spam, upload malware, probe or attack the Service, bypass limits (for example by creating many accounts), scrape it at scale, or resell it without our written permission. We may suspend accounts that do.
5. Plans, billing and trials
- Free includes up to 100 active prompts, the latest 5 versions of each prompt (older versions are kept and open again after upgrading), 3 community submissions a month (approved ones do not count) and 100 AI answers a month, shared by the prompt tester, apps and Improve with AI.
- Individual and Team are paid subscriptions billed in advance, monthly or yearly as you choose at checkout, through our payment provider, Stripe. Prices are shown on the pricing page and at checkout; taxes are added where they apply. The Team price includes a number of seats shown on the pricing page, and each seat above that is charged per period. Subscriptions renew automatically at the end of each period (a month or a year), for the same price and number of seats, until you cancel. We email you before a yearly subscription renews. We charge the payment method you gave at checkout at the start of each period.
- New team workspaces get a free trial of 14 days. If you do not subscribe when it ends, the workspace becomes read-only: nobody can edit, but everyone can still read and export everything. Nothing is deleted.
- You can cancel at any time online from Plan & billing, with no need to contact us. The plan stays active until the end of the paid period and then ends; we do not refund the unused part of a period unless these terms or the law require it. You can change the number of seats at any time; changes are prorated.
- Right to withdraw (consumers). If you are a consumer in the EU, the UK or another place that gives a right to withdraw from distance contracts, you may withdraw within 14 days of subscribing and get a refund. At checkout you ask us to start the Service immediately and acknowledge that you lose this right once the Service has been fully provided or, where the law allows, once you start using it; if you withdraw within the 14 days after using it, you pay a proportionate amount for what you used. To withdraw, write to [email protected]. This does not apply to business customers.
- If a payment fails we retry and tell you by email and in the app. If it keeps failing the subscription ends.
- We may change prices with at least 30 days' notice by email or in the app. The new price applies from your next renewal after the notice period. If you do not agree, you can cancel before the new price applies and you will not be charged it.
- Fair use. "Unlimited" on the Individual and Team plans (prompts, folders, community submissions and tests on your own AI key) means unlimited for normal personal or business use. These plans are not for automated bulk use, reselling access, or sharing one account between several people. If an account's usage is far beyond what is typical, we will first contact the account owner and ask them to reduce it or move to a custom plan, and give them reasonable time to respond. We do not cut off access automatically.
6. Availability and changes
Prompier is early-access software. We work to keep it running but do not promise it will always be available or error-free. We may add, change or remove features, and will give reasonable notice of changes that significantly reduce what a paid plan includes. Export your prompts whenever you like from Import / export.
7. Ending the agreement
You can stop using Prompier and delete your account at any time (see the privacy policy for what happens to your data). We may suspend or end your access if you break these terms, if the law requires it, or if your account has been unused for a long time (after warning you by email). If we end a paid account for no fault of yours we will refund the unused part of the paid period. "Fault" here means that you broke these terms (including the acceptable use rules), abused the Service or our staff, or used the account for something illegal, or that ending the account is needed to comply with the law.
8. Our responsibility
The Service and community content are provided "as is" without warranties of any kind, to the extent the law allows. Prompier helps you organize prompts; it does not produce or check the output of AI tools. To the extent the law allows, we are not liable for indirect or consequential losses, lost profits or lost data, and our total liability for any claim is limited to the amount you paid us in the 12 months before it arose (or 100 USD if you paid nothing). Nothing in these terms limits liability that cannot be limited by law, such as for fraud or for death or personal injury caused by negligence, or your statutory consumer rights.
9. Changes to these terms
If we change these terms in a way that matters we will tell you by email or in the app at least 30 days before the change applies. If you keep using Prompier afterwards you accept the new terms; if you do not agree you can close your account.
10. General
These terms, together with the privacy policy, are the whole agreement between us about the Service. If a part of them is found unenforceable the rest still applies. Not enforcing a right is not giving it up. You may not transfer your account without our consent. The law and courts that apply are those of the place where Prompier LLP is established, except where mandatory consumer law gives you the right to use your own.
