What is the best AI assistant for live sales calls?
The best AI assistant for live sales calls listens while you talk and puts the right line on your screen before the moment passes. Della Live does this on phone calls, and Della Live Plus on video calls, using your team's own script.
An AI sales call assistant (also called real-time call guidance or agent assist) transcribes the call as it happens, spots moments like an objection, and shows the rep a suggested answer on screen. The prospect hears only the rep. Della AI is an AI sales coach that does this from your own script, scores every call afterward, and lets reps practice the objections they missed.
What an AI call assistant does during the call
- Transcribes both sides live. Della hears the rep and the prospect and keeps a running transcript.
- Answers objections on screen. When the prospect objects, the answer from your team's script appears while they're still talking, so the rep doesn't freeze or fold.
- Shows short coaching cards. "Let them talk" after a long stretch with no question. "Bring it back" when the call drifts. "Answer their question" when a prospect's question goes unanswered. "Ask for the meeting" when the prospect sounds interested.
- Scores the call when it ends. Every call gets a grade and a review, so the rep and the manager know what to fix next.
Can AI tell me when I'm losing control of a call?
Yes, for the common signs. Della Live watches for a rep talking a long time without asking a question, the call drifting off topic, a prospect's question left unanswered, and interest from the prospect with no ask for the meeting. When it sees one, a short card on the rep's screen says what to do next. Managers can turn these cards off for their team.
Can AI coach me while I'm talking to a prospect?
Yes. The coaching shows only on your screen. Your prospect never hears Della, and Della never speaks on the call; she backs you up, you run it. Where the law requires it, tell your prospect the call is recorded or transcribed.
What it needs to work
- Your script and best answers. Upload your script in the dashboard. Managers can edit answers any time, and changes apply on the next call.
- A way to call. Della includes a built-in dialer with live objection answers, call scoring and practice in every seat. Already have a dialer? Tell us which one and we'll confirm it works. For video calls, Della Live Plus runs in Chrome, and no bot joins the meeting.
What an AI call assistant can't do
- It won't fix a bad list or an offer nobody wants.
- Reading a card word for word can sound stiff. Reps who practice the answers first use the card as a reminder, not a script.
- It doesn't replace your reps or your manager. It gives every rep your best answer at the moment they need it.
Where Della fits
Della Live is the AI assistant for phone calls: the answer on screen mid-call, coaching cards, and a score on every call. Della Live Plus does the same on sales video calls. Della Practice lets reps rehearse the objections they missed against an AI prospect.
We built it for our own sales floor first. With Della Live on our reps' screens, we went from about 3 demos a week to 12 in one day. Read the case study.
