Big Sister AI Company Terms of Service
Effective Date: October 29, 2026 · Version tos-2026-14
If you signed a separate Cover Page or Order Form to access the Product with the same account, and that agreement has not ended, the terms below do not apply to you. Your separate agreement applies instead.
This Agreement is between Big Sister AI Company, a Delaware corporation ("Provider", "Big Sister AI", "we"), and the company or person that creates an account for, accesses or uses the Product ("Customer", "you"). It consists of (1) the Cover Page below, which contains the Order Form and Key Terms, and (2) the Common Paper Cloud Service Agreement Standard Terms Version 2.1, incorporated by reference. Together these are the "Agreement".
How you accept. You accept this Agreement by checking the box that references it when you create a workspace, or by accessing or using the Product. If you are accepting on behalf of a company, you represent that you are authorized to bind that company, and "Customer" means that company. We record the version you accepted and when.
Cover Page
Order Form
Framework Terms. This Order Form incorporates and is governed by the Framework Terms, made up of the Key Terms below and the Common Paper Cloud Service Agreement Standard Terms Version 2.1, which are incorporated by reference. Modifications to the Standard Terms made on this Cover Page control over conflicts with the Standard Terms. Capitalized words have the meanings given on this Cover Page or in the Standard Terms.
Cloud Service. Big Sister AI, a sales-performance platform at https://app.big-sister.ai. It ingests recordings and transcripts of Customer's sales calls and meetings from a source Customer connects (a notetaker such as Fireflies, or a dialer), and, on Team and Custom plans, records from Customer's CRM. It scores each interaction from 0 to 100 against a written skill rubric, cites the transcript evidence behind each score, aggregates the results into rep, team and pipeline views, lets Customer challenge a score through the Referee review process, and keeps an Interactions Log and reports. Scoring is performed with third-party large language models under the no-training terms in this Agreement.
Plans and Fees. Current plans, prices and what each includes are published at https://www.big-sister.ai/pricing (the "Pricing Page") and are incorporated by reference. At the Effective Date of this version:
| Plan | Fee | Minimum | Interaction sources |
|---|---|---|---|
| Free | $0, no payment method required | None | One source (notetaker or dialer) |
| Solo | $30 per scored rep per month | 1 scored rep | One source (notetaker or dialer) |
| Team | $50 per scored rep per month | 1 scored rep | One source plus one CRM |
| Custom | From $5,000 per month, by separate Order Form | Per Order Form | Any, including custom connectors |
A "scored rep" is a User who holds the Sales role in Customer's workspace and is not deactivated. Users who hold only the Owner, Admin or Manager role are not charged. A pending Sales invitation counts as a scored rep from the moment it is sent until it is revoked. Adding or removing a scored rep changes the Fee from the next Subscription Period.
Founder rate. The per-rep Fee shown in the Product when Customer creates its workspace is locked for that workspace for as long as the subscription continues without interruption on the same plan, even if the Pricing Page later shows a higher rate. Provider may change the Fee for a workspace only by giving at least 30 days' notice by email, and a change applies from the next Subscription Period after the notice period ends.
Free plan. The Free plan is for one person. A Free workspace has exactly one User, its Owner, and cannot invite other Users. Each calendar month (UTC) the Owner may choose up to 5 calls from the current month in Customer's connected source to be scored; each call is at least one minute long and can be chosen once. Unused choices do not carry over. Scored calls stay in the workspace while it remains open. The Free plan also includes one Rematch trial of 33 minutes per workspace, used on a prepared practice call provided by Provider, which does not renew. Each business email domain may hold one Free workspace, and each person using a personal email address (such as gmail.com) may hold one; closing a Free workspace does not free that domain or address for another. Customer uses the Free plan for business purposes, to review its own sales calls. Provider may change the Free plan's limits, or end the Free plan, on 30 days' notice by email to the Owner; scored calls stay available for at least 30 days after the Free plan ends, or Customer may move to a paid plan. Provider may suspend a Free workspace that breaches this Agreement or is used to get around these limits. For a Free workspace: the Fee is $0; the Subscription Period is one calendar month, renewing automatically until Customer closes the workspace or Provider ends the Free plan; the warranty in Section 6.1 of the Standard Terms does not apply and the Product is provided as is, with Section 6.5 applying in full; and Technical Support is best effort with no target response time. Customer may close a Free workspace at any time from the Product's settings or by email to hello@big-sister.ai. Upgrading to Solo or Team starts a paid Subscription Period, and the one-time scoring snapshot below applies from that first payment.
Activation. There is no free trial of the paid plans. The first paid Subscription Period includes a one-time scoring snapshot of Customer's recent call history: up to 30 days on Solo and up to 3 months on Team, subject to what Customer's connected source makes available.
Fair use. Each plan includes up to 150 scored interactions per scored rep per Subscription Period. Above that, Provider may queue further interactions to the next period or contact Customer about a Custom plan. Provider will not charge for overage without Customer's agreement.
Order Date. The Effective Date.
Subscription Period. One month, or one year where Customer selects annual billing on the Pricing Page. Each Subscription Period renews automatically for the same length unless Customer cancels under the Non-Renewal Notice Period.
Payment Process. Card payment through Provider's payment processor, Stripe. Provider charges the card on file at the start of each Subscription Period for the scored reps in the workspace on that date. Fees are in US dollars, exclusive of taxes, and are non-refundable except where this Agreement says otherwise. Customer manages its card, invoices and receipts in the billing portal linked from the Product.
Non-Renewal Notice Period. The Owner may cancel on Customer's behalf at any time from the Product's billing settings. Cancellation takes effect at the end of the current Subscription Period, and no further Fees are charged. Provider will not refund the unused part of a Subscription Period except under Sections 5.4 or 6.4 of the Standard Terms.
Technical Support. Email support at hello@big-sister.ai during business hours, 8 AM to 5 PM Central Time, Monday to Friday, excluding US federal holidays. Target first response: one business day.
Use Limitations.
- The Product analyzes sales interactions only. Customer will not use it to analyze personnel, activities or communications that are not sales interactions, and will not use it to make decisions about hiring, firing, compensation or discipline without independent human review.
- Customer may connect only sources and CRMs the Product supports, and only accounts that Customer owns or is authorized to connect.
- Customer will not submit Prohibited Data. Sales calls sometimes contain such data incidentally; Customer will not direct the Product at it, and Provider does not extract or index it.
- The Product is designed for business customers located in the United States. It may be used elsewhere, but support hours, pricing and data-protection terms are written for US customers. See the Data Processing Agreement for other jurisdictions.
Modifications to the Standard Terms
The following replace or add to the Common Paper Standard Terms Version 2.1 for every Customer under this Agreement. Where a modification below conflicts with the Standard Terms, the modification controls.
1. Section 1.6 (Machine Learning) is replaced with:
Provider will not use Customer Content, Customer's Confidential Information, Personal Data, or outputs generated for Customer to train, fine-tune, or otherwise develop any artificial intelligence or machine learning model, whether or not the data has been aggregated, anonymized, de-identified or combined with other data, without Customer's specific prior written consent. Provider contracts with the third-party model providers listed at https://www.big-sister.ai/subprocessors on terms under which Customer inputs are not used to train those providers' models. This Section does not restrict Provider from (a) processing Customer Content through models as necessary to deliver the Product, including generating scores, summaries and coaching output; (b) internal quality review of the Product as delivered to Customer; or (c) using aggregate statistical measures that contain no Customer Content and from which neither Customer nor any individual can reasonably be identified. AI-generated output is assistive and is not a substitute for human judgment.
2. Section 3.1 (Personal Data) is replaced with:
Provider processes Personal Data in Customer Content on Customer's behalf under the Big Sister AI Data Processing Agreement at https://www.big-sister.ai/dpa (the "DPA"), which is incorporated into and forms part of this Agreement. The DPA applies to all Customer Content, regardless of the jurisdiction of the data subjects. If Customer requires a signed copy of the DPA, or a DPA on Customer's own form, Customer may request one at notices@big-sister.ai; a signed DPA replaces the incorporated one from the date of signature.
3. New Section 2.3 (Recording consent) is added:
Customer is solely responsible for obtaining all consents and giving all notices that Applicable Laws require for the recording, transcription and analysis of every call, meeting or other interaction that reaches the Product. This applies whether Provider, Customer, or a third-party tool that Customer has connected (such as Customer's own notetaker or dialer) made the recording, and it includes the laws of jurisdictions that require every participant's consent. Customer will not submit a recording it was not entitled to make. Customer's breach of this Section is a Customer Covered Claim.
4. Section 10 (Confidentiality) is supplemented with:
All Customer Content is Confidential Information of Customer without any requirement that it be marked or designated as confidential. Provider may disclose Customer Content only to its personnel and to the subprocessors listed at https://www.big-sister.ai/subprocessors, in each case under written confidentiality obligations no less protective than this Section, and only to provide the Product. Provider's confidentiality obligations for Customer Content continue for five years after the Agreement ends, and for Personal Data, trade secrets and security information for as long as the information remains confidential or protected by Applicable Laws. Because the Product's own confidentiality terms cover Customer Content, no separate non-disclosure agreement is required for Customer to use the Product.
5. Section 5.5 (Effect of Termination) is modified so that:
Provider will delete Customer Content within 30 days after the Agreement ends, and in any event within 30 days after Customer's written request, except for copies in routine encrypted backups, which are deleted no later than 35 days after the primary deletion and remain protected under Section 10 until deleted. Retention of Customer Content during the term is governed by the DPA.
6. New Section 6.5 (AI output) is added:
Scores, skill assessments, summaries and coaching output are generated by automated analysis of transcripts and may be incomplete or wrong. Provider does not warrant that any score is accurate or that any recommendation will produce a sales result. Customer will apply human judgment before acting on output, and will not treat output as the sole basis for an employment decision about any individual.
7. Section 11.2 (Modifications) is supplemented with:
Provider may update this Agreement by publishing a new version at https://www.big-sister.ai/terms-of-service. For a change that materially reduces Customer's rights or increases its obligations, Provider will give at least 30 days' notice by email to the Owner before the change takes effect, and Customer may cancel before that date without penalty. Other changes take effect when published. Each version carries a version identifier, and Provider keeps a record of the version each Customer accepted.

Change log
| Version | Date | Change |
|---|---|---|
tos-2026-14 | 2026-10-29 | Free plan added: one person, up to 5 chosen calls scored per calendar month, one 33-minute Rematch trial on a prepared call, best-effort support, and Provider may change or end it on 30 days' notice. "There is no free trial" now reads "There is no free trial of the paid plans". The General Cap Amount now has a $100 floor, so that a Customer who has paid no Fees keeps a remedy. Paid plans are unchanged and no Customer loses a right, so this takes effect on publication (section 11.2). |
tos-2026-13 | 2026-10-24 | Workspace roles defined: one Owner per workspace, who is Customer's primary contact and the only User who can cancel, accept updated Terms on Customer's behalf and transfer ownership; Admins manage Users, billing details and sources; Managers see the team. Notices go to the Owner. "Viewer" removed from the free-account list, since the Product has no such role. Customer keeps every right it had, exercised through its Owner, so this takes effect on publication (section 11.2). |
tos-2026-12 | 2026-10-15 | Team plan minimum lowered from 5 scored reps to 1: Team is $50 per scored rep with no floor. This reduces no Customer right and increases no obligation, so it takes effect on publication (section 11.2). The rest of the text is unchanged. |
tos-2026-11 | 2026-10-14 | Version bump only: the Terms' own text is unchanged. Incorporates the updated DPA (dpa-2026-11: individuals whose call was not answered, and the telephone numbers and call metadata held for them, are named in Annex 1, with a 24-month retention for call metadata) the updated Privacy Policy (privacy-2026-11: call logs named as Customer Content) and the updated subprocessor list (subprocessors-2026-10.2). Acceptance is recorded under this version id. |
tos-2026-10 | 2026-10-01 | Rewritten for self-serve plans. Replaced the Machine Learning default (Standard Terms 1.6) with a no-training commitment; incorporated the DPA for all Customer Content; made Customer Content confidential without marking, which removes the need for a separate NDA; added recording-consent and AI-output sections; card billing through Stripe; removed the two-seat minimum, invoice terms and the CRM list; deletion within 30 days; 30-day notice for material changes; acceptance recorded by version. |
tos-2025-04 | 2025-04-10 | First Common Paper version. |
