When to choose Marnie
Your answers, not the internet’s.
Marnie only uses content you’ve approved. If it isn’t in your library, Marnie doesn’t use it.
Knows what’s safe to say.
Internal pricing notes and roadmap details stay internal. Every source has a trust level, and every answer says what reps can share.
Honest when unsure.
When Marnie doesn’t have a solid answer, it says so instead of filling the gap, and you see the question.
The same answer for every rep.
No prompt-writing skills needed. Reps ask in plain words and get the answer you’d give.
Built for deals.
Battle cards for the deal in front of the rep, customer stories with the case study to send, and approved responses to objections.
When ChatGPT may fit better
For everyday work, a general assistant is the right tool: drafting emails, summarizing calls, researching an account, brainstorming. Use it alongside Marnie. Reach for Marnie when the answer is going in front of a prospect and has to be the approved one.
Frequently asked questions
Can’t we just upload our content to ChatGPT?
You can, and it helps. But ChatGPT still blends your files with everything else it knows, doesn’t know what’s internal-only, and gives different answers depending on how each rep asks. Marnie answers only from your library, checks every claim, and keeps answers consistent.
Does Marnie use AI too?
Yes. The difference is what it’s allowed to use: only content you approve, checked before a rep sees it.
Do reps have to learn a new tool?
No. They @mention Marnie in Slack and ask, the way they’d ask a colleague.
Does Marnie work in Microsoft Teams?
Marnie runs in Slack today.
