Using both
Big Sister connects to Gong with a technical admin key pair and scores every call recorded in Gong. Gong stays your recorder, and your tool for outreach and forecasting if you use it for those. Big Sister adds one scored standard on top: every rep and every AI agent gets a Sales Score from the same 18 skills, and every score opens down to the line in the transcript.
For a team already on Gong, that makes Big Sister an addition more than a swap. The overlap is coaching from real calls, and there the difference is the written method: each skill has a written bar for every level, and a person settles a rep's dispute.
Where each fits better
Gong fits better
You need recording, conversation intelligence, sales engagement, forecasting and AI agents from one vendor. Or your CRM is Salesforce today, which Gong integrates with and Big Sister does not connect to yet.
Big Sister fits better
You already record calls, in Gong or elsewhere, and want every rep and AI agent scored the same way, with the evidence linked and a person settling disputes. Or you want to try it free on 5 of your own calls first.
What Big Sister is not
Big Sister is not a call recorder, a CRM, a dialer or a forecasting tool. If you are choosing between the two for recording or forecasting, that choice is Gong. See the integrations page for every source Big Sister reads today.

FAQ

How does Gong pricing compare with Big Sister pricing?
As of November 9, 2026, Gong's pricing page says licenses are priced per user with a platform fee based on the number of users, without published numbers. Big Sister has a free plan for 5 of your own calls a month and prices paid plans per scored user, human or AI agent, on its pricing page.
What happens if a rep disagrees with a Big Sister score?
The rep disputes it, and a person settles the dispute. Every score links to the moment in the transcript that earned it, so both sides argue from the same line.
