Live roleplay
How do RepLab and Second Nature differ?
RepLab and Second Nature both give reps an AI partner to practice sales conversations with. Here’s how they compare, and where RepLab is different.
RepLab
RepLab is the AI roleplay platform for frontline sales and service teams. Reps practice with AI customers built from your playbook, get scored against your scorecard, and managers see who is ready in every location.
- Ramp new hires faster, with certification on your own scenarios before their first customer conversation
- Full control over personas, scenarios and scorecards, no engineering or services team needed
- Built for frontline teams across stores, branches, call centers and the field, with readiness by location
- SOC 2 Type II audit in progress, GDPR compliant, and your conversations never train external AI models
Chosen by healthcare, home services and multi-location teams that need every rep ready, not just the top performers.
Second Nature
Second Nature calls itself the AI role play training solution used by Fortune 100 companies to ramp faster and scale practice. It offers video avatar simulations and connects to any LMS through SCORM or LTI.
May be a good fit if:
- Your team is mostly sales reps who need onboarding and certification at scale
- Video avatar simulations matter to how you train
- You need SCORM or LTI integration with your LMS

Realistic practice for your highest-stakes conversations
Readiness starts with practice that feels like the real thing. RepLab AI customers react to what the rep says and how they say it, so reps build confidence before a real customer is on the line.
Configurable AI customers
Build personas with goals, moods, objections and difficulty, from a first-time buyer to a customer who is ready to cancel.
Voice-first practice
Reps talk out loud, on the phone or desktop, the way they will in a real conversation. No script to lean on.
Your own scorecard
Every session is scored 0 to 100 against your criteria and weights, with the exact lines to try next time.
“Scaling our practice sessions with instant feedback loops has acted as a force multiplier for onboarding, significantly accelerating our reps’ time-to-proficiency.”

See readiness before it shows up in results
Know who is ready, everywhere
Most teams only find out a rep was not ready after a lost deal or an unhappy customer. RepLab shows readiness by rep, team and location before the real conversation happens.
Readiness by location
Compare every store, branch and team on the same scorecard, and see exactly where practice is needed.
Custom scoring
Scorecards that reflect how your team defines a great conversation, with your criteria, weights and pass marks.
Certification
Set the minimum scores reps must reach before they talk to customers, and see who has passed.
Manager visibility
See progress and weak skills by rep without sitting in on every session.
Close the loop between practice and performance
Most platforms stop at practice. RepLab pairs with SalesAsk, so real customer conversations are scored on the same playbook and weak moments become the next roleplay.
Self-serve scenarios
Build a scenario in minutes
Start from 40+ ready-made scenarios or build from a prompt, a script or your playbook. Set the persona, objections and difficulty, no code and no tickets.

“With RepLab our reps are not just practicing, they are perfecting. The feedback loop is immediate — a rep can practice a procurement objection at 8am, refine their approach, and walk into the 10am meeting sharp. That simply wasn't possible before.”
