FAQ

Short answers.

More in the full details, or email hello@metricbrief.net.

Are you an agency?
No. We don't run or advise on ads, listings or pricing. Your team makes the decisions.
How is this different from Seller Central or Amazon's AI assistant?
Metricbrief is a managed service: we set up your recurring review, check it against your existing reports, deliver it on your schedule, and host and maintain the setup. It brings sales and ads together by product and works alongside your existing tools.
What do I need to do during the trial?
Grant read-only access to your reports, share your current report if you have one, and give feedback on the weekly review.
What happens after the trial?
You choose whether to continue at the agreed price. No minimum term. If you stop, you get an export and we delete your data.
Does our data go to Claude or ChatGPT?
The figures in your review are calculated from your Amazon reports without AI. An AI model, used through Metricbrief's account, writes the review's text from those figures. Follow-up questions run in your team's own Claude or ChatGPT account, which we connect only to the data included in your review. Your company's plan with Anthropic or OpenAI sets how they handle what the assistant reads.
