Wink AI is a real-time sales assistant built for teams that sell products over the phone. It listens to the call, knows what the customer bought before, and puts one in-stock product from your catalog on the rep's screen, with a line they can say out loud. Balto is a contact-center platform built around real-time guidance, with prompts, checklists and knowledge answers, plus QA, coaching and an AI voice agent.

Both help agents during live calls. The difference is what they help with. This page is as of October 2026, and everything it says about Balto comes from Balto's own website.

The short version

What to say vs what to sell. Balto's sales page describes Dynamic Prompts that show agents "the best discovery questions and rebuttals." Wink tells the rep what to offer: the product that fits this customer, right now.
Suggestions you can sell right now. Wink's suggestions come straight from your live catalog: in stock, in the right size, at a sensible price.
Purchase history drives the pitch. Wink loads the customer's past orders when the call starts, so a pendant bought on Tuesday becomes the matching earrings on Friday.
One suggestion, not a checklist. Wink shows the single best item with a reason the rep can say, and stays quiet when nothing fits.
Tuned on what sells. We track whether each suggestion was pitched and whether the customer bought, and tune Wink on those outcomes.

Why phone sales teams choose Wink

It turns every order call into a second sale

Most inbound order calls end the moment the order is placed. Your best reps don't stop there: they remember the customer's last purchase and mention what goes with it. Wink gives every rep that instinct. It answers what the customer asks for and also spots upsell and cross-sell openings on its own, from the conversation and the customer's history.

It knows your catalog, live

A suggestion is only useful if the rep can sell it. Wink connects to your product catalog and checks stock, size and price before it suggests anything, so every product on screen is a real item the rep can add to the order. Reps can also type a question mid-call, like "matching necklace under $150?", and get products they can sell without putting the customer on hold.

It's fast where it matters

A suggestion that arrives after the moment has passed is worth nothing. In Wink, answers to direct questions always come first, and nothing proactive is allowed to slow them down. Read how we made real-time upsells fast.

It's judged by revenue

Wink is tuned on whether suggestions were pitched and whether customers bought them. Attach rate and revenue per call are the numbers that matter.

It covers the call after it ends

Every Wink call gets a transcript and a summary, and Wink Audit AI can score every call against your own quality rubric, including sales behaviors and compliance requirements, so QA teams can review far more than a small manual sample.

How Balto approaches it

Balto describes "one unified system where humans and AI collaborate to drive quality, efficiency, and revenue for contact centers." Its Agent Assist gives "real-time answers and guidance on every call" from your knowledge bases. Its sales page adds Real-Time Coaching, which alerts managers so they can guide agents live, and Win Rate Analysis, which tests phrases against each other. It also offers automated QA scored against your playbook, coaching tools, call notes synced to your CRM, and Togo, an AI voice agent for repeatable calls like scheduling and order status. Its homepage lists industries such as insurance, healthcare, banking and collections.

That makes Balto a strong fit for scripted, regulated conversations. Wink focuses on the product sale.

Proven on real sales floors

ShopLC, a retailer of jewelry, gemstones, beauty and home products, has rolled out Wink to 50 personal shoppers. Wink helps them recommend the next product during live calls and makes QA audits faster and more thorough. Read how ShopLC uses Wink. TJC's personal shoppers use Wink too.

Works with the phone system you have

Wink runs in the browser next to your dialer and integrates with Five9, which Balto also lists as an integration. The Wink Companion for Windows brings in call audio from other softphones without a browser microphone prompt. There is nothing to rip out: most teams are live within 4 weeks.

When Wink AI is the better choice

Your reps sell products over the phone, and the second item in the basket is where the growth is.
Your catalog is large and changes daily, so suggestions have to be in stock, in the right size, at a sensible price.
Repeat customers matter, and their past orders are the best guide to what they'll buy next.
Reps need to look up products mid-call without putting the customer on hold.
You run Five9, or your reps use softphones on Windows.

When Balto may fit better

Your calls follow a script, and the biggest lever is discovery questions and objection handling.
You need live compliance checklists in a regulated industry such as insurance or collections.
You want an AI voice agent to take routine calls like scheduling.

Frequently asked questions

Is Wink AI a Balto alternative?

For teams selling products over the phone, yes. Balto centers on what the agent says. Wink centers on what the agent offers: products from your live catalog, chosen from the conversation and the customer's history.

Does Wink work with Five9?

Yes. Wink runs in the browser next to the dialer and integrates with Five9.

Does Wink show scripted prompts during calls?

That isn't Wink's focus. Wink suggests products and answers product questions during the call, then scores every call against your own QA rubric afterwards, which can include sales behaviors and compliance requirements.

How long does it take to get Wink live?

Most teams are live within 4 weeks. Wink connects to your product catalog, customer records and phone system, then your admins invite agents.

How should I compare the two in a pilot?

Use your own calls, not a scripted demo. Measure how quickly help appears after the customer stops talking, how often reps act on it, and the change in attach rate and revenue per call. Our guide to real-time agent assist has more questions to ask any vendor.
