Ruby
Live AI call assistant for macOS that suggests the right question mid-call and writes your notes after.
Ruby is worth it if two things are already true: you take high-stakes calls where one question changes the outcome, and you already pay for Claude Code. The live prompting, the no-bot privacy model, and screen-share invisibility are a genuinely different shape from post-call notetakers like the recap-first crowd, and using your own Claude subscription avoids a second AI bill. If you are on Windows, on the Claude desktop app rather than the terminal CLI, or you need team dashboards, Ruby is not the tool — general notetakers cover that ground. Try it free first; without Claude Code the value drops off sharply.

Skip Ruby if you are not on macOS 14.4+ with an active Claude Code terminal subscription, or if you need team-level coaching dashboards and shared analytics rather than a private in-call assistant.
Ruby itself is a free download, but it needs a paid Claude Code subscription — the terminal CLI, not the desktop app — so the real cost is that separate Claude plan.
Ruby is priced for individuals: the Mac app is free and you bring an existing Claude Code subscription, which is where the actual money goes. That makes it cheaper than per-seat meeting-intelligence platforms that charge every user a monthly fee, and roughly comparable to just paying for Claude Code alone. For a team of five, the math flips — five Claude Code subscriptions and no shared dashboard is more expensive and less useful than one team-tier notetaker.
In short
Ruby — Live AI call assistant for macOS that suggests the right question mid-call and writes your notes after. Best for Solo founders running discovery calls on a Mac, Product managers doing live user interviews, Sales AEs in high-stakes demos. Free to use.

About Ruby
Ruby is a live AI call assistant for macOS. It listens to your call as it happens and slides you the question worth asking, or the detail worth remembering, at the moment it helps — instead of recapping everything afterward like a conventional notetaker. You sign in with Claude and Ruby uses your own Claude Code subscription for the reasoning, so there is no separate AI bill. Transcription runs in Ruby itself and feeds that context into Claude as you talk. Two things stay private: no bot joins the call, so the other side has nothing to notice, and Ruby's window is hidden from screen share, so only you see the suggested question. Before a call you brief Ruby on who you are meeting and attach a skill — the-mom-test, sales, hiring, or one of your own. During the call you just talk. Afterward Ruby writes the notes, and the transcript and notes remain yours. It is built for founders, PMs, AEs, and recruiters whose high-stakes calls live or die on asking the right thing in the moment. It is a solo-operator tool: there are no team dashboards, shared coaching analytics, or admin consoles. Ruby requires macOS 14.4+ on Apple Silicon (M1 and later) or Intel, plus a Claude Code subscription — the terminal CLI, not the Claude desktop app. The download itself is free.
Behind the Verdict
The interesting decision Ruby makes is timing. Most meeting AI is a recorder with a summarizer bolted on — useful, but it only tells you what already happened. Ruby is positioned around the gap between the moment and the follow-up, which is exactly where deals and interviews are won or lost, and the product surface reflects that: a single always-on overlay that surfaces one question or one detail rather than a transcript pane you have to read while also listening. That narrowness is a strength. There is no dashboard to configure, no bot to invite, no participant list to negotiate. The privacy model is the second differentiator and it is architectural, not a setting. Because no bot joins the call and Ruby's window is excluded from screen share, the counterparty has nothing to notice and nothing to object to. For recruiters and AEs that matters more than feature count — a live coaching bot visibly sitting in the meeting changes how the other person behaves. Local transcription plus your own Claude subscription also means the transcript and notes stay under your account rather than accumulating in a vendor's workspace. The costs are real and worth stating plainly. Ruby is macOS 14.4+ only, Apple Silicon or Intel — no Windows, no Linux, no web app. It requires Claude Code, the terminal CLI specifically, so the Claude desktop app does not qualify. That is a narrower prerequisite than "a Claude subscription" sounds, and it is the single biggest reason a buyer bounces. There is also no team layer whatsoever: no shared skill library across seats, no manager view of what questions reps did or did not ask, no aggregated analytics. A sales org that wants coaching visibility cannot get it here. Where it fits: a solo founder, PM, AE, or recruiter on a Mac who already lives in Claude Code and takes a handful of consequential calls a week. Where it does not: teams that need dashboards, anyone on Windows, and anyone whose real problem is post-call documentation rather than in-call judgment — a plain notetaker solves that for less friction. The free download makes the trial cost nothing but time, and the time to first value is roughly one call.

Real-world workflow fit
Concrete scenarios for the personas Ruby actually fits — and what changes day-one when you adopt it.
You sign in with Claude, brief Ruby on the prospect and attach a skill, then take the call on your Mac. Ruby transcribes locally, feeds the context to Claude, and slides you a question about the pricing objection the prospect just raised.
Outcome: You leave the call with the qualifying detail you would normally have thought of in the car afterward, and Ruby has already written the notes.
Ruby runs silently during the screen-shared demo — no bot in the participant list and the suggestion window excluded from the share. When the buyer mentions an integration concern, Ruby surfaces the question that clarifies whether it is a blocker or a nice-to-have.
Outcome: The demo stays clean for the buyer while you get prompting the counterparty never sees.
You load the hiring skill before the interview. As the candidate describes a project, Ruby suggests probing on the specific metric or the decision they avoided.
Outcome: Structured notes and a clearer read on the candidate, without a second interviewer in the room.
Use Cases
- Get the closing question suggested mid-demo while you are still talking
- Probe deeper on a customer discovery call without losing the thread
- Run a hiring interview solo with live prompts on what to dig into
- Have structured notes waiting the moment a call ends
- Brief Ruby before a call with a skill so its suggestions match your goal

Limitations
- Ruby requires a paid Claude Code subscription — the terminal CLI, not the Claude desktop app — so a Claude desktop plan alone will not work.

What this tier adds
Free entry point: the Mac download costs nothing, and you sign in with your existing Claude Code subscription rather than paying Ruby a separate fee.
Where the pricing makes sense

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.
Download is free; count on about ten minutes for a solo founder or AE — download the correct Mac build (Apple Silicon or Intel), sign in with your Claude account, and attach a skill before your next call. Recruiters and PMs may want one full call to tune their custom skill and confirm the window behaves as expected during screen share. There is no admin, seat, or workspace setup because there is
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 manual note-taking: download Ruby for Mac, sign in with Claude, and let the first call produce the notes instead of writing them yourself.
- →From a general notetaker: keep your existing tool for archived meetings and run Ruby alongside it on high-stakes calls until you trust the live suggestions.
- →From a live coaching service with a bot: drop the bot invite and rely on Ruby's no-bot, screen-share-hidden overlay instead.
- ↗To a general notetaker: move your recurring meeting capture there if you mainly need post-call documentation rather than in-call prompts.
- ↗To a team meeting-intelligence platform: switch if you need shared dashboards, seat management, and aggregated coaching analytics.
