Ruby
A live assistant for your calls.
💬
Ruby listens to your call as it happens and chimes in with the question worth asking — right when the moment's right. You just take the call.
What it is
Ruby is an AI assistant you hire for a live call. You brief it once, take the call, and it listens as you talk — sliding you the question worth asking or the thing to remember, right when it helps.
The problem
The best question always comes to you after the call. Notetakers tell you what happened — none of them help while it's still happening.
Private by default
- Only you can see it — hidden from screen share
- No bot joins — nothing for the other side to notice
- Runs on your own
Claudesubscription - The transcript and notes stay yours
How it works
- Sign in with Claude. Ruby uses your subscription for the brains — no extra AI bill.
- Brief it. Tell Ruby who you're meeting and bring a skill —
the-mom-test, sales, hiring, or your own. - Take the call. Ruby's own transcription feeds Claude as you talk; it chimes in when the timing's right.
Who it's for
Founders, PMs, AEs, recruiters — anyone whose high-stakes calls live or die on asking the right thing in the moment.
