You're Shipping Blind.
Your Clients Pay the Price.
Real callers are nothing like your test calls. Here's what happens on the calls you never hear.

Hallucinated Pricing

Your agent invents service packages and quotes random numbers. One wrong price kills trust instantly.

Avg cost: $800/deal lost to wrong pricing

Silence Death Spirals

Caller goes quiet for 5 seconds. Agent panics, repeats itself, or just hangs up. The lead is gone.

23% of calls end in silence drops

Memory Wipes Mid-Call

Caller corrects their name on turn 2. By turn 6, agent uses the wrong name. Asks for the timezone twice.

41% drop in booking rate
Every broken call is a lost deal. The average voice AI agency loses $2,400/month per client to undetected agent failures.

20-Scenario Stress Test

13 Voice Behaviors. 5 Generation Modes. Zero Mic Time.

AI generates 20 realistic scenarios from your agent's live prompt. Interruptions, silence, emotional escalation, mumbling, rapid-fire details, topic switches, and adversarial attacks. All tested automatically.

Full test suite in under 5 minutes
Auto-Optimizer

One-Click Fix. Push Direct to Your Platform.

Reads every failure, generates the exact prompt fix, and pushes it directly to Retell or Vapi via API. No copy-pasting. No manual rewriting. Re-test instantly to verify.

5 minutes from broken to production-ready
Built for Teams That
Ship Agents at Scale

Red-Team Testing

Adversarial attack scenarios that probe for prompt injection, data leaks, safety violations, and off-topic hijacks. Find vulnerabilities before bad actors do.

CI/CD API

Run tests from GitHub Actions, GitLab CI, or any pipeline. Set score thresholds that block deploys automatically. Voice testing as infrastructure-as-code.

Production Monitoring

Ingest and score every live call via webhooks. Custom alert rules for score drops, safety violations, and latency spikes. Weekly digest emails with agent health trends.

Fleet Management

Manage hundreds of agents across teams. Bulk test, compare performance, and track leaderboards. Built for agencies running client portfolios at scale.

Human-in-the-Loop Calibration

Grade calls yourself. The system learns your standards with Bayesian weight adjustments. Your scoring gets smarter with every human review session.

PDF Reports + Golden Datasets

Auto-generate shareable reports with full metric breakdowns. Baseline your best calls as golden datasets for regression testing on every update.

Common Questions
Which voice platforms do you integrate with? +
Retell AI (full API integration), Vapi, ElevenLabs, Bland AI, and LiveKit. We pull your agent's prompt, settings, and tools directly from the platform. Connect in 30 seconds.
What exactly does the scoring system measure? +
25+ metrics across 9 dimensions: task completion, safety, empathy, conversation flow, repetition, latency (P50/P90/P99), interruption handling, sentiment, accuracy, and audio quality. Deterministic metrics like response time can't be faked by LLMs.
How does autonomous testing work? +
The engine fetches your agent's live prompt, then generates 20 realistic conversation scenarios using 5 generation modes and 13 voice behavior types (interruptions, silence, emotional escalation, mumbling, etc). Each scenario is scored across all 25+ metrics. No mic needed. Full results in under 5 minutes.
Can I integrate VoxGrade into my CI/CD pipeline? +
Yes. The REST API lets you run tests from GitHub Actions, GitLab CI, or any pipeline. Set minimum score thresholds to automatically block deploys when agents regress. Voice testing as infrastructure-as-code.
Can I push fixes directly to my live agents? +
Yes. The Auto-Optimizer reads every failure, generates the exact prompt fix, and pushes it directly to Retell or Vapi via API. Original prompts are backed up automatically. Re-test instantly to verify the fix worked.
What about production monitoring? +
On Agency plan, every live call gets ingested via webhooks and scored automatically. Set custom alert rules for score drops, safety violations, or latency spikes. Weekly digest emails summarize agent health trends across your entire fleet.
What if it doesn't work for me? +
30-day money-back guarantee on all paid plans. No questions asked. Start with the free tier to see your agents' real scores before upgrading.
