Koji vs Chorus (ZoomInfo): Conversation Intelligence vs AI Customer Research (2026)

Short answer: Chorus by ZoomInfo is a conversation intelligence platform — it records, transcribes, and analyzes the sales and customer calls your reps are already having so managers can coach and forecast. Koji is an AI customer research platform — it runs brand-new, AI-moderated voice and text interviews with customers, prospects, and users who would never sit on a sales call. Chorus mines conversations you happen to have. Koji creates the conversations you need. They solve different problems, and the strongest teams in 2026 run both.

If you are comparing them, you are probably trying to answer one question: "Do I already have the customer insight I need buried in call recordings, or do I need to go ask?" This guide breaks down where each tool wins.

What Chorus (ZoomInfo) Is Built For

Chorus.ai, acquired by ZoomInfo in 2021, is one of the most established conversation intelligence tools on the market. It automatically captures every sales call, demo, and customer meeting, then turns those recordings into searchable, analyzable data. Its core strengths are:

• Automatic call capture across phone, video, and email, with full transcription and search.
• Deal intelligence that links conversations to CRM opportunities and flags pipeline risk.
• Coaching workflows so managers can review reps' calls, build playlists, and scale winning talk tracks.
• Competitive and objection tracking that surfaces how often competitors or pricing come up.

Chorus is a sales-team tool first. Pricing is enterprise and not publicly listed — third-party reports put it around $8,000/year for a three-seat minimum with additional seats billed annually, often bundled into a broader ZoomInfo data contract. That makes it powerful for revenue organizations but heavy for a product, design, or marketing team that just wants to understand customers.

What Koji Is Built For

Koji is an AI-native research platform. Instead of passively recording calls, Koji actively conducts interviews. You write a research brief, Koji's AI interviewer talks to each participant one-on-one — by voice or text, in their own language — and asks intelligent follow-up questions in real time. Then it analyzes every transcript automatically and assembles a shareable report.

The difference is reach and intent. A sales call only happens with people already in your pipeline who agreed to talk to a rep. Koji can interview churned users, trial drop-offs, non-buyers, and silent power users — the people whose voices never make it into a CRM. And because the AI moderator runs 24/7, you can talk to 100 customers in a week without scheduling a single meeting.

A few capabilities that matter for research specifically:

• Six structured question types — open_ended, scale, single_choice, multiple_choice, ranking, and yes_no — so a single study captures rich qualitative stories and clean quantitative data you can chart. See the structured questions guide.
• Adaptive AI follow-ups (one to three probes per question) that dig into the "why" behind every answer, the way a skilled human researcher would.
• Automatic analysis with two-cycle coding: the AI labels themes per response, then clusters them into a canonical codebook across all interviews — no manual tagging.
• Real-time reports that update as responses arrive, with quotes traced back to the exact moment in each transcript.

Koji vs Chorus at a Glance

When to Choose Chorus

Pick Chorus if your primary goal is sales execution: coaching reps, shortening ramp time, spotting deals about to slip, and understanding what happens on live calls. If you are a revenue leader and your team already lives in ZoomInfo, Chorus is a natural extension that makes existing conversations more useful.

When to Choose Koji

Pick Koji if your goal is customer understanding at a scale and depth that ad-hoc sales calls can't reach. Koji shines for:

• Churn and cancellation research — interview every churned user automatically, not just the few who took a sales call. Pair it with churned customer interviews.
• Pricing and willingness-to-pay studies using scale and ranking questions.
• Concept and message testing before launch.
• Continuous discovery — a standing pool of customer interviews running every week.

Because Koji's quality gate only charges a credit for conversations that score 3 or higher, you only pay for interviews that produce usable insight. A text interview costs 1 credit and a voice interview 3 credits, so a month of discovery often fits inside a single plan.

The Honest Take: Use Both

Chorus and Koji are not really competitors — they sit on opposite sides of the insight equation. Chorus extracts intelligence from conversations your sales team is having. Koji manufactures conversations your research and product teams need. Many teams pipe both into the same decision: Chorus tells you what prospects say while buying; Koji tells you what customers think after they've lived with the product. For a deeper look at the "analyze existing calls vs run new interviews" tradeoff, see conversation intelligence for customer research and turning sales calls into customer insight.

If you are choosing only one and you sit outside the sales org, Koji is almost always the better starting point: it is self-serve, it talks to the customers a CRM can't reach, and it turns raw conversations into decisions without a manual analysis step.

A Real-World Scenario

Picture a B2B SaaS company watching a promising deal stall. Chorus does its job perfectly: it surfaces the call where the prospect raised a security objection, flags that "competitor X" came up three times, and lets the manager coach the rep on a better response. That is real, useful intelligence about this deal and this rep.

But it can't answer the bigger questions the product and marketing teams are asking: Why are non-buyers — the prospects who never booked a second call — walking away? Is the security concern a one-off or a pattern across the whole market? What would make the silent majority trust the product? Those answers don't exist in any call recording, because those people never got on a call.

This is where Koji comes in. The team launches a study targeting recent evaluators who didn't convert, drops the interview link into a nurture email, and lets the AI interviewer run 80 conversations over a weekend — in five languages, with adaptive follow-ups on every trust and pricing objection. By Monday, the auto-generated report ranks the top five reasons evaluators churned and quotes the exact words behind each. Chorus explained one lost deal; Koji explained the pattern behind fifty.

That is the practical division of labor: Chorus makes your existing sales conversations smarter, and Koji manufactures the customer conversations your strategy depends on. Neither replaces the other, but if you only have budget for one and you sit in product, design, marketing, or research, Koji is the higher-leverage starting point because it reaches the people a CRM never will.
