Ask the question that
actually matters.
Ruby is your on-call assistant. It listens live and surfaces the one thing worth saying — right when you need it.

Your assistant, on every call.
One note blooms when there’s something worth saying — and fades on its own. You never owe Ruby a click.
Three steps. Zero friction.


Built around one rule.
Silence is the default — not a failure. Everything else follows from that.












Playbooks
Create custom rules for Ruby to follow. Tell it what to watch for, what to surface, and how to show up on any kind of call.
Hidden from screen share
The gem is visible only to you, protected at the OS level. The other person never sees it.
Prep your way
One sentence or a full grilling session. Ruby preps you as much or as little as you need.
Silent by default
Ruby only speaks up when it has something that fits the sentence you're on right now.
On-demand hotkey
Ask Ruby what to ask at any moment. Zero interruption risk.
What you’ll need.
Ruby is in beta and improving fast.
Ruby works on any call. It listens, and speaks up when it counts.
Interview. Discovery. 1:1. Negotiation. Whatever the call — Ruby is there when you need it, quiet when you don’t.
