Call Flow is an AI training platform for sales and customer support teams. Instead of learning on real customers, reps practice realistic calls against AI-powered buyers and callers โ€” then get instant, objective feedback on every session.

How it works

  1. Practice realistic AI calls. Choose from 700+ real-world scenarios across seven categories (hosting & infrastructure, website & commerce, refunds & cancellations, compliance & privacy, de-escalation, soft skills, and custom scenarios). Six caller temperaments and three difficulty levels mean no two calls play out the same.
  2. Get instant grading and coaching. Every call is scored in seconds across five dimensions: rapport, objection handling, active listening, compliance, and resolution โ€” with specific coaching tips reps can apply immediately.
  3. Certify your team. Supervisor dashboards show readiness scorecards, skill heatmaps, and improvement trends, so managers know exactly who is ready to go live.

Key features

  • Branching AI conversations with emotional arcs and unpredictable responses
  • Custom scenario builder using your own products, objections, and personas
  • Voice and text simulation modes
  • Certification workflows with supervisor review and score overrides
  • Team dashboards, skill heatmaps, and progress tracking
  • SSO, role-based access, SOC 2 compliance, GDPR ready

Results customers report

  • Up to 40% faster ramp time for new hires
  • 35% higher CSAT and first-call resolution
  • 28% lower agent turnover

Pricing starts at $49.99/month. A 30-day full-access trial with up to 20 seats is available for $1.

Questions & Answers

As answered by people managing Glasp and CallFlow.dev.

Why should a person choose your product over its competitors?

CallFlow.dev's answer:

Competitors may offer generic conversation practice, live coaching platforms, or basic AI chatbots, but CallFlow.dev emphasizes hyper-realistic voice-style simulations, volume of scenarios, real-time multi-dimensional scoring, and enterprise training outcomes (ramp speed + CSAT/FCR lifts). It is particularly compelling for teams that need to scale training without proportionally scaling manager time.

What makes your product unique?

CallFlow.dev's answer:

Scale and realism of scenarios: 700+ dynamic, adaptive AI scenarios covering refunds, upselling, technical troubleshooting, compliance, de-escalation, complex objections, and more. These are not static scripts but branching, emotionally progressive conversations.

โ€ข Caller personas and difficulty levels: Six realistic AI caller personas that evolve emotionally, available at beginner, intermediate, and advanced difficulty.

โ€ข Real-time evaluation and coaching: Instant AI scoring across key dimensions (rapport, objection handling, resolution quality, professionalism, regulatory compliance) plus personalized coaching tips after every practice session.

โ€ข Customization depth: A built-in custom scenario creator that lets teams import their own product knowledge, FAQs, policies, and objection scripts so training matches the exact brand, products, and customer types.

โ€ข Manager/ops focus: Certification/readiness scorecards, team analytics, performance tracking, and data that supervisors can use to guide coaching and certify agents at scale.

โ€ข Outcome orientation: Designed around measurable business results (e.g., reported up to 40% faster ramp-to-productivity for new agents, improvements in first-call resolution and CSAT) rather than generic soft-skills practice.

How would you describe the primary audience of your product?

CallFlow.dev's answer:

The primary audience is call centers, sales teams, and customer support organizations specifically training directors, operations leaders, contact-center executives, and managers responsible for onboarding and continuous agent performance.

Secondary but closely related users include BPOs, insurance, telecom, and other high-volume customer-facing operations that face long ramp times, high turnover, compliance requirements, or complex objection/de-escalation needs. It targets teams that want data-driven readiness certification rather than informal practice.

What's the story behind your product?

CallFlow.dev's answer:

CallFlow.dev originated from real-world call-center and sales-training pain points experienced by its founders. Traditional training was slow, inconsistent, manager-intensive, and left new agents underprepared for live customers.

The platform was built to solve that by giving agents unlimited, realistic AI-powered practice with instant feedback and coaching, while giving leaders the analytics and certification tools needed to scale quality.

It launched as a professional SaaS focused on measurable reductions in ramp time (targeting ~40%) and improvements in performance metrics, with ongoing emphasis on enterprise adoption, custom scenarios, and workforce-development outcomes.

Which are the primary technologies used for building your product?

CallFlow.dev's answer:

advanced AI for natural dialogue, emotional progression of personas, evaluation across rapport/objection handling/compliance/etc., and personalized coaching.
