Terms of service

Effective 4 September 2026

1. The agreement

These terms are a binding agreement between you and Propab (“Propab”, “we”, “us”) about your use of propabai.com and the Propab service (the “Service”). By creating an account or using the Service you accept them. If you use the Service for an organisation, you confirm you have authority to bind it, and “you” includes that organisation. Our privacy policy explains how we handle your data and forms part of this agreement. An organisation that has signed a separate agreement with us is governed by that agreement where the two differ.

2. What the Service is

Propab runs an automated research agent. Given a scientific question or a longer program of work, the agent searches the scientific literature, plans and executes computations in an isolated environment, produces artifacts — tables, figures, code, notebooks, reports — and writes up its findings together with a record of the sources, code and models behind each result. A task may run for minutes, hours or days, and may ask for additional compute where your plan or a compute account you connect allows it. The Service is offered to researchers, institutions and companies; it is not intended for personal use by minors.

3. Your account

• You must be at least 18 and able to enter a contract. One person per account. On a team plan each member has their own account within the shared workspace.
• Sign-in is by one-time code to your email or through an identity provider; keep that email and provider secure, because whoever controls them controls your account. Tell us promptly if you believe your account has been used without your permission.
• You are responsible for everything done under your account, including by members you add to a workspace you administer.
• Give us accurate account and billing information and keep it current.

4. Your research content

“Research content” means everything you put into the Service — questions, instructions, uploaded files, messages to a running task — and everything the agent produces for you in response, including the record of how it was produced.

• You own it. You keep every right in what you upload, and we assign to you whatever rights we may have in what the agent produces for you, to the extent permitted by law. We claim no ownership of your research content.
• What we may do with it. You give us the limited permission we need to operate the Service: to store your research content, to process it and send the necessary parts to the AI model you selected and to the infrastructure that runs your task, to show it back to you and to the members of your workspace, and to keep the copies that backups and legal obligations require. Nothing more. We do not use research content to train models, and we do not publish it.
• You are responsible for it. You must have the right to upload and process what you upload — including any personal data it contains and any licensed material such as paywalled full text — and you must comply with the terms of the datasets and sources you bring.
• Similar outputs. Because the agent responds to what it is asked, another researcher who asks a similar question may receive a similar result. Ownership of your output does not extend to other people’s outputs.

5. Acceptable use

You agree not to use the Service, and not to allow anyone using your account, to:

• break any law, or breach export-control or sanctions rules that apply to you;
• research, design or produce weapons capable of mass casualties, or otherwise pursue work whose purpose is to harm people;
• access or attempt to access another workspace’s data, escape the isolated environment a task runs in, probe or attack the Service or the providers behind it, or interfere with other researchers’ use;
• upload malicious code, or content you have no right to use;
• resell, sublicense or offer the Service to third parties as a service of your own, or use automated means to extract its behaviour at scale to build a competing service;
• circumvent plan allowances, the compute queue, or any other limit; or
• misrepresent the agent’s output as human-authored where that would mislead — for example in a submission that requires disclosure.

We may investigate suspected breaches and take proportionate action, including limiting a task, a feature or an account, as described in section 14.

6. Plans, allowances and billing

• Usage. Each plan includes daily usage of model inference that resets every day at midnight UTC, under a monthly ceiling. Your workspace shows how much of today’s usage is used and when it resets. A run that reaches the daily limit or the monthly ceiling is paused with its work kept, and continues after the reset. Some plans state their daily usage as a multiple of another plan’s.
• When a window is spent. Work that is already running continues. New model calls wait for the window to reset, and new compute requests join a lower-priority queue behind researchers who still have allowance; you and the agent are told, and the queue position is shown live. We do not charge overage.
• Model choice. You choose the model a task uses, or leave the choice to the Service. Different models consume the allowance at different rates; the workspace shows how much time each buys before you start.
• Payment. Paid plans are billed in advance, monthly or yearly as you choose, by our payment processor acting as merchant of record; the price, currency, tax and renewal terms are shown at checkout and on your receipt. Your subscription renews automatically until you cancel.
• Cancellation and refunds. You can cancel from the workspace at any time; you keep the plan until the end of the period you have paid for, and you are not charged again. Payments are not refunded, except where your local law gives you a right to withdraw that cannot be waived.
• Price changes. We may change prices for future periods. We email you at least 30 days before a change affects what you pay, and you may cancel before it takes effect.
• Free plan and trials. A free plan and any promotional code we issue are for evaluation; we may change or withdraw them, and we may limit one per person or institution.
• Taxes. Prices exclude taxes unless stated; the payment processor applies the tax due for your billing country.

7. Compute you connect

If you connect a compute provider account of your own, jobs that you or the agent start on it are contracted and billed by that provider to you under its terms; Propab meters and shows them but does not charge for them. Every job carries a cost ceiling and a deadline set by you or by the agent, and the Service enforces both: when either is near, the job is warned and given time to save its work; when reached, the job is stopped. You are responsible for the credential you provide and for the provider’s charges, including for a job that you asked us to stop but that the provider failed to stop.

8. Scientific results and reliance

The agent’s findings are produced by an automated system working from the literature, your data and the models you selected. Every result carries the record of how it was produced — the sources read, the code run, the model used — precisely so that you can check it. A result that has not been checked by you is a hypothesis, not a fact. You are responsible for any decision, publication, submission, experiment or product based on the Service’s output, for meeting your field’s standards of verification and disclosure, and for compliance with any rules that apply to the use of automated tools in your work.

9. Our intellectual property

The Service — its software, design, models of working, documentation, literature index and the name and marks “Propab” — belongs to us or our licensors. These terms give you a limited, non-exclusive, non-transferable right to use the Service for your research while your account is in good standing, and nothing more. The scientific literature the agent reads belongs to its authors and publishers; the Service gives you no rights in it beyond those you already have.

10. Feedback

If you send us suggestions or feedback about the Service, we may use them to improve it without obligation to you. Feedback is not research content, and we will not attribute it to you publicly without your permission.

11. Disclaimers

The Service is provided as is and as available. To the fullest extent the law allows, we make no warranty that it will be uninterrupted, error-free or secure, that any result will be accurate, complete, novel or fit for a particular purpose, or that the literature index is complete or current. The Service is not a substitute for your own scientific judgment, and no output is professional, medical, legal or financial advice.

12. Limitation of liability

To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive loss, or for lost profits, revenue, data or goodwill, arising from your use of or inability to use the Service; and our total liability to you for all claims in any twelve-month period is limited to the amount you paid us for the Service in that period, or one hundred US dollars if you paid nothing. Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, for fraud, or the statutory rights of consumers in the European Economic Area, the United Kingdom, India or elsewhere.

13. Your responsibility for your use

If a third party brings a claim against us because of your research content, your breach of these terms, or your use of the Service in breach of law, you will defend and compensate us for the resulting losses and costs, provided we tell you promptly, let you control the defence, and assist reasonably at your expense. This does not apply to consumers where local law does not allow it.

14. Suspension and ending the agreement

• You may close your account at any time from the workspace or by email; we delete your data as the privacy policy describes.
• We may suspend a task, a feature or an account, or end this agreement, if you materially breach these terms, if required by law, or if continuing would create a security or legal risk. We tell you why and, unless the breach is one where a warning would cause harm or is not permitted, give you a chance to fix it.
• If we discontinue the Service, we give at least 60 days’ notice and a way to export your research content, and refund any prepaid period we do not provide.
• Sections 4, 8 to 13, 16 and 17 survive the end of the agreement.

15. Changes to the Service and to these terms

The Service evolves; we may add, change or retire features. We do not remove your ability to export your research content. We may change these terms; when a change affects your rights or what you pay, we email account holders at least 14 days before it takes effect, and you may end the agreement before then. Continuing to use the Service after the effective date means you accept the change.

16. Governing law and disputes

These terms are governed by the laws of India, and the courts of Bengaluru have jurisdiction over disputes arising from them, except that if you are a consumer in the European Economic Area or the United Kingdom, you keep the protection of your local consumer law and may bring a claim in your local courts. Before either of us starts a claim, we agree to try to resolve the matter by writing to each other and discussing it in good faith for 30 days.

17. General

These terms and the privacy policy are the whole agreement between you and us about the Service. If a provision is found unenforceable, the rest remains in force. Our not enforcing a provision is not a waiver. You may not assign this agreement without our written consent; we may assign it to a successor of our business, and will tell you if we do. Notices to you go to the email address on your account; notices to us go to the address below.
