### About Ruby

Ruby is a meeting software application that listens to live audio during calls and suggests questions for the user to ask. The tool displays these suggestions through a small pill interface visible only to the user. It operates by connecting to the user's existing Claude subscription for inference.

### Review

This review examines the functionality of Ruby as a real-time meeting assistant. The application focuses on prompting users with follow-up questions during live conversations. It does not merely transcribe or summarize the audio.

#### Key Features

- Before a call begins, the application helps users define their objectives and identify specific topics to monitor during the conversation.
- During the meeting, a small pill interface displays suggested questions in real time based on the live audio transcription.
- After the conversation ends, the tool generates a written recap of the discussion.
- Users can manually add custom instructions to the memory to personalize the types of questions the AI suggests.

#### Pricing and Value

Ruby is currently free during its beta phase. The tool does not charge a separate fee for AI inference, as it routes processing through the user's existing Claude subscription. Future pricing models are not yet defined.

#### Pros

- Visual prompts remain hidden from other participants through a small pill interface visible only to the user.
- Audio files are not stored on the company's servers, as the transcription passes through a relay via a third-party cloud API.
- The application eliminates separate AI billing by relying on the user's pre-existing Claude subscription for inference.

#### Cons

- The software requires a Mac computer and the installation of Claude Code in the terminal, creating a barrier for users without these specific setups.
- Automatic pattern learning from previous calls is unavailable, meaning the AI does not automatically improve based on past successful question sequences.
- Professionals working exclusively on Windows or Linux machines are not well suited for this application, as it strictly requires a Mac environment.

Ruby functions as a real-time prompting tool for individuals conducting user interviews, sales calls, or investor meetings. Mac users who want live suggestions for follow-up questions during conversations will find the application fits their workflow.
