The short answer
Yes, this kind of tool exists: a real-time AI call assistant listens to a live call on your computer and shows you a suggested reply while the other person is still talking. Sayble, NextSay, SalesGhost, Convo and Cluely all do a version of it; they differ in price, platforms, whether a bot joins the meeting and whether they answer from your own documents.
Sayble is a desktop app for Mac and Windows. It hears both sides of a call on your computer, shows the line to say next, writes the recap and follow-up email when you hang up, answers from your own documents and works in 10 languages. One full 5-minute live session is free, no card; Pro is $39.99/month, or $24.99/month for the first 12 months with a founder code.
How AI that listens to calls works
- It hears the call on your computer. Both sides, from the app you already use: Zoom, Google Meet, Microsoft Teams, Slack huddles or a browser dialer. Nothing joins the meeting.
- It transcribes live and labels who said what.
- It spots the moment that needs an answer (a price objection, a hard question, a stall such as "send me some info") and drafts a reply, using your own material if you uploaded it: price sheets, scripts, FAQs.
- The line appears on your screen while the other person is still talking. You read it, adapt it, and say it in your own words.
- When you hang up, it writes the recap and drafts the follow-up email from the real transcript.
A real example: what Sayble suggested
| What the other person said | Line Sayble suggested |
|---|---|
| Them: "It's too expensive." (a $1,850 water-heater quote) | "Most of that cost is the permit, expansion tank, new gas flex line, and haul-away, things cheaper quotes often leave out. Want me to break down the $1,850 line by line for you?" |
| Them: "Just send me some info." (office cleaning) | "Happy to. What bugs you most about your cleaning right now: the quality, the crew changing, or the price?" |
Real lines Sayble suggested on recorded practice calls in October 2026, with that business's own price sheet and rebuttal script loaded as context. Wording changes from call to call; you decide what to say.

| Hears both sides | Suggestions need the other person's words, not only yours. | Yes, with speaker labels |
| Uses your own material | Generic answers sound generic; your price sheet makes them specific. | Upload PDFs, scripts, pricing, FAQs |
| Languages | Bilingual teams and clients switch languages mid-call. | 10 languages, auto-detected |
| After the call | The follow-up is where many deals stall. | Recap and follow-up email drafted at hang-up |
| Price and trial | You should be able to try it on a real call first. | 5-minute live session free; Pro $39.99/mo (founder $24.99/mo for 12 months) |

Where Sayble falls short
- Desktop only. Sayble runs on Mac and Windows. A phone call has to run through your computer (a softphone or browser dialer).
- Suggestions, not a script you must read. You stay in charge of what you say.
- The free session is 5 minutes. Enough to see it work on one real call; after that it is a paid plan.

Frequently asked questions
Is there an AI that listens to calls and gives suggestions in real time?

Does the other person see the AI?
Sayble runs on your own computer. No bot joins the meeting and nothing appears in the participant list.

Yes. Sayble works with any call that runs on your Mac or Windows computer, including Zoom, Google Meet, Microsoft Teams, Slack huddles and browser dialers, without an integration.
Can it answer with my own prices and scripts?
Yes. Upload price sheets, scripts, FAQs or playbooks before the call and Sayble answers from that material.
Do I have to tell the other person?
Consent rules for recording and transcription depend on where you and the other person are. If you are unsure, say at the start of the call that you use an AI assistant to take notes.
