Ruby
Live AI call coach for macOS that feeds your Claude Code for real-time question suggestions.
If you're on high-stakes calls and already pay for Claude Code, Ruby delivers real edge — the right question, live, hidden from screen share. But it's macOS-only, requires the terminal CLI, and has no team features. Try it free; if you don't have Claude Code, the value drops sharply.

Skip Ruby if you don't have a Claude Code subscription or don't use macOS 14.4+, or if your main need is post-call transcription rather than live, in-the-moment coaching.
You must have an active Claude Code subscription; without it, Ruby doesn't function — that's an ongoing cost on top of any Ruby fees (currently free).
Ruby is free to download, but it requires a Claude Code subscription (typically $20–$25/mo) — so the real cost is your existing Claude plan. Compared to enterprise call-coaching platforms like Chorus or Gong (which charge per-user with annual contracts), Ruby is far cheaper for solo operators. But if you don't already pay for Claude Code, the initial cost is higher than simple notetakers like Otter.ai (free tier available).
In short
Ruby — Live AI call coach for macOS that feeds your Claude Code for real-time question suggestions. Best for Founders on discovery calls needing sharper live questions, Product managers gathering requirements during user interviews, Sales AEs in high-stakes demos where one question can close. Free to use.

About Ruby
Ruby is a live AI call assistant for macOS that listens to your call as it happens and chimes in with the question worth asking — right when it helps. It transcribes locally and feeds that context to your own Claude Code subscription, so there's no extra AI bill. The transcription and notes stay yours, and nothing is shown on screen share — only you see the suggested question or the thing to remember. Built for founders, PMs, AEs, and recruiters, Ruby turns high-stakes calls into a sharper conversation. You brief it before the call with a skill — the-mom-test, sales, hiring, or your own — and it listens as you talk, sliding you the exact question to ask or the detail to remember. After the call, it writes the notes. It's private by default: no bot joins the call, so the other side never notices. Ruby requires macOS 14.4+ (Apple Silicon or Intel) and a Claude Code subscription (the terminal CLI, not the desktop app). The download is free, and you sign in with Claude to use your existing subscription. Unlike general notetakers that only recap after the fact, Ruby helps while the call is happening. It's a focused tool for solo operators — no team dashboards or analytics.
Behind the Verdict
Ruby's core pitch is sharp: stop thinking of the perfect question after the call ends. For founders doing discovery, PMs running user interviews, sales AEs in demos, and recruiters probing candidates, the live nudge can be the difference between a closed deal and a lost thread. Ruby's design choices reflect that focus: it runs on your own Claude Code subscription (no extra per-minute AI costs), does local transcription (so your call content stays yours), and hides its suggestions from screen share (so the other party never sees the coaching). The pre-call briefing and custom skills mean you can tune it to your specific context, whether that's the-mom-test for product discovery or a hiring rubric for interviews. Where Ruby stumbles is its hard boundaries. The macOS 14.4+ requirement (Apple Silicon or Intel) locks out Windows and Linux users and older Macs. The dependency on Claude Code — not the Claude desktop app — is a specific, tech-forward requirement that narrows the audience further. You need to be comfortable with a terminal CLI. And there are no team features: no shared call libraries, no analytics, no coach dashboards. That makes Ruby a solo operator's tool, not a revenue-ops platform. If you want post-call transcription only, tools like Otter.ai or Fireflies.ai cover that at scale. But if you want live, private coaching during the call and you're already in the Claude ecosystem, Ruby is a solid fit. The free download and pay-as-you-go via your own Claude subscription lower the barrier to trying it.

Real-world workflow fit
Concrete scenarios for the personas Ruby actually fits — and what changes day-one when you adopt it.
Before a customer interview, you brief Ruby with the-mom-test skill. During the call, Ruby listens and suggests a probing question about the customer's pain. You ask it, get a valuable insight, and Ruby writes the post-call recap.
Outcome: You leave the call with a sharper understanding and notes ready — without scrambling to remember details.
You're demoing your product to a prospect. Ruby, using the sales skill, slides a question about budget timing. You use it, uncover a decision timeline, and the demo stays on track.
Outcome: You close the next step more confidently because you asked the right question live.
During a candidate interview, you use the hiring skill. Ruby suggests a follow-up on a technical decision the candidate mentioned. You probe deeper and get a clearer picture of their experience.
Outcome: You make a more informed hiring decision with a structured recap.
Use Cases
- Ask the one sharp question that closes a deal during a live sales demo
- Never forget to probe deeper during a customer discovery call
- Get real-time coaching on hiring interviews without a second person
- Receive a structured recap immediately after the call ends
- Prepare for calls with a brief that customizes Ruby's suggestions

Limitations
- Ruby requires a separate Claude Code subscription (the terminal CLI, not the desktop app) and works only on macOS 14.4+ (Apple Silicon and Intel).
- It does not join the call as a bot, so suggestions rely entirely on local transcription quality.
- There is no web or mobile version, and no team features for shared learning or analytics.

What this tier adds
Free entry point with full core functionality; requires your own Claude Code subscription for AI processing.
Where the pricing makes sense
The company stage and team size where Ruby's pricing actually pencils out — and where peers do it cheaper.
Ruby is free to download, but it requires a Claude Code subscription (typically $20–$25/mo) — so the real cost is your existing Claude plan. Compared to enterprise call-coaching platforms like Chorus or Gong (which charge per-user with annual contracts), Ruby is far cheaper for solo operators. But if you don't already pay for Claude Code, the initial cost is higher than simple notetakers like Otter.ai (free tier available).
Setup time & first value
How long it actually takes to get something useful out of Ruby — broken out by persona, not the marketing-page minute.
For a Solo Founder: ~10 minutes — download, sign in with Claude, brief Ruby for the call, and start using it (first call within minutes). For a Sales AE: ~15 minutes to install, create a sales skill, and test it on a mock call. For a Recruiter: ~10 minutes to set up the hiring skill and integrate with your interview flow.
Switching to or from Ruby
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Otter.ai / Fireflies.ai (if you want live coaching): Install Ruby, sign in with Claude, and brief it for your next call — your previous notes remain in the old tool; start fresh with Ruby for live suggestions.
- ↗To a team-based coaching platform (e.g., Gong, Chorus): Export any valuable call recaps manually; Ruby doesn't offer bulk export, so it's easy to switch if you need team analytics.
