Luster AI Review: New and Shiny AI Role Play Startup

Luster AI Review: Lightweight but Limited

Live role-plays take time to organize, often feel forced, and rarely mimic the pressure of real sales calls. Luster AI is one of a growing number of platforms trying to solve that with automated, AI-powered sales simulations.

But how does it compare to other tools in the AI sales training space?

Luster AI: What It Is

Luster is an AI-driven platform for cold call role-plays and objection handling drills. Reps can practice common call types and get immediate feedback without a manager in the room. It’s positioned for newer reps and fast-growing teams who need consistent practice at scale.

Quick Setup, Lightweight UX

Admins can upload talk tracks, objection handling frameworks, and persona details. Reps pick a scenario and start practicing.

Post-call feedback includes:

• Transcript
• Basic AI score

The dashboard makes it easy to assign scenarios and track team activity over time.

Where It Works Best

Luster is well-suited for:

• Onboarding SDRs
• Practicing cold openers
• Reinforcing objection handling
• Async role-play certification

If you’re running bootcamps or weekly training, it helps reps get more reps—without needing a coach on every call.

It also includes a set of pre-built skill drills, which can make it easier to spin up training quickly without building everything from scratch.

Where It Feels Limited

There are several drawbacks to note:

• High latency and long delays in the Voice AI make the experience feel sluggish, which can break immersion during role-plays.
• The AI doesn’t do a good job mimicking real prospects—responses often feel generic, shallow, or overly scripted.
• Role-play customization is limited: it doesn’t appear that users or admins can fully customize conversations or adapt the AI to specific personas or industries.
• There’s no real-call analysis or advanced customization like scorecard logic or adaptive scripts.

In short: what you see is what you get.

How It Compares

Best For: Teams Who Need Quick, Repeatable Practice

Luster is most helpful if your goal is consistency over complexity. It helps reps:

• Build confidence
• Stay sharp on messaging
• Practice objections with less overhead

But if you're aiming to simulate longer sales cycles, handle industry-specific objections, or gain deeper insights into rep behavior, other platforms may offer more.

Final Take

Luster isn’t aiming to replace coaching or live call review. For what it is—a lightweight way to scale basic sales training role-plays for newer reps—it can be effective.

Just know the limits:

✅ Worth considering if:

• You're onboarding reps quickly
• You don't need any customization
• You care more about repetition than realism

❌ You might outgrow it if:

• You sell into complex markets
• You need in-depth discovery practice
• You want integrations with real-call data
