## What is Ruby?

Ruby is an AI call assistant that runs on Mac and helps during live conversations. It listens to the call as it happens, then surfaces a question, reminder, or follow-up at the moment it may be most useful.

The workflow is simple: sign in with Claude, brief Ruby with the meeting context and a skill, then take the call. Ruby uses the user's Claude subscription for the AI layer and keeps the assistant private to the user during the call.

## What can Ruby do?

### Live call listening

Ruby listens to the conversation in real time and watches for moments where a question or reminder may help.

### Context briefing

Before the call, you can tell Ruby who you are meeting and assign a skill such as the-mom-test, sales, hiring, or a custom prompt.

### Timely on-screen prompts

Ruby surfaces the question worth asking when the timing fits, instead of waiting until the call is over.

### Private display

Only the user can see Ruby, and it is hidden from screen share so the assistant is not visible to other participants.

### No meeting bot

Ruby does not join the call as a bot, which keeps the interaction on the user's side of the conversation.

### Claude-based processing

Ruby uses the user's Claude subscription for the AI work, and the transcript plus notes stay with the user.

## Use Cases

### Founders on customer calls

Use Ruby to keep high-stakes customer conversations moving and ask the question that would otherwise come to mind only after the call.

### Product managers in discovery interviews

Brief Ruby with the interview context so it can prompt for a useful follow-up while the discussion is still active.

### Sales calls and objections

Keep Ruby on hand during sales conversations to help surface the next question or the point worth remembering in the moment.

### Recruiting interviews

Use Ruby to stay present in interviews while still having a prompt available for a missing detail or follow-up question.

### Custom live-call workflows

If your call style does not fit a preset use case, Ruby can be briefed with your own skill and used as a personal call assistant.
