## Coval

Coval is an evaluation and quality platform built specifically for voice AI agents — the automated phone assistants that handle support, banking, insurance, and booking calls. The pitch is simple and unglamorous: the riskiest call is the one you never tested, and a handful of manual QA calls will not surface the accents, interruptions, policy traps, and tool errors that decide whether an agent holds up at scale. Coval gives product, QA, operations, and compliance teams one measurement layer to answer that question with evidence rather than anecdotes.

The platform works as a three-part loop. Simulation runs thousands of realistic conversations against an agent before launch, covering personas, conversational turns, and hard policies. Observe runs evaluations against live production traffic to catch quality drift the moment prompts, models, workflows, or vendors change. Review routes the conversations that matter to human reviewers, whose judgments then sharpen the automated metrics for the following release — so every production insight becomes the next test.

Coval is aimed at teams putting voice agents in front of large customer bases. Its use cases are organised by industry — customer support, financial services, healthcare, hospitality, insurance, retail, and travel — as well as by build approach, with options for agent platforms, in-house builders shipping on LiveKit, Pipecat or custom stacks, and vendor bakeoffs. The company reports figures such as a 217% improvement in agent accuracy within seven days, 3.1 million evaluation metrics run weekly, and under 15 minutes to a first simulation via CLI, alongside documentation, an API reference, and a trust center.

**Pricing & Plans:** Contact for pricing. Coval offers a free trial and demo-based sales; specific plans are quoted based on usage and testing needs.

- **Voice AI simulation:** Pressure-test agents with thousands of realistic callers, accents, interruptions, noisy audio, and hard policy traps that manual QA cannot cover.
- **Production evaluations:** Run evaluations on live conversations to spot where resolution, safety, or customer experience is slipping before complaints arrive.
- **Human QA review loop:** Route the calls that matter to human reviewers and convert their judgment into sharper automated metrics for the next release.
- **Vendor and model bakeoffs:** Compare voice agent vendors and prompts side by side on the same behavioural criteria before deciding.
- **API, CLI and benchmarks:** Access documentation, an API reference, and benchmark data to integrate evaluations into existing CI/CD and observability pipelines.

**Strengths:** Covers pre-launch simulation, production monitoring, and human review in one loop; Industry-specific playbooks for support, finance, healthcare, insurance, retail and travel; Works with hosted agent platforms as well as in-house LiveKit or Pipecat stacks; Public benchmarks, API reference, and a trust center support self-evaluation

**Limitations:** Pricing is not published, so you must talk to sales to scope costs; Focused on voice agents rather than text-only LLM applications; Value depends on having enough call volume to justify continuous evals

## Relyable

Relyable was built by a team that develops voice agents and treats testing as a first-class part of shipping them. Rather than rely on human spot-checks, it uses AI to create personas and scenarios that mimic real callers — old and angry, young and confident, different accents, moods and goals — and then runs those conversations in parallel against your deployed agent. Each call is analysed automatically, so problems surface before a single real customer encounters them.

Evaluation is driven by a rubric you control. You can weight criteria such as end-to-end task completion, freedom from fabricated policy or pricing, stable customer sentiment, clean interruption handling, latency under a p95 target and appropriate out-of-scope handoff. Relyable tracks pass rates and seven-day trends for each criterion, giving a quantified picture of whether a change helped or hurt.

In production, the platform becomes a monitoring layer. Live calls are logged and scored in real time, and Relyable pages you only when a threshold is crossed — through Slack, email, PagerDuty, Opsgenie, Linear or a webhook. The company is headquartered in Melbourne, Australia, and is associated with NVIDIA Inception, ElevenLabs Grants and Microsoft for Startups.

**Pricing & Plans:** Relyable uses credit-based pricing where credits cover both simulated and live calls. Core is $500/month with 50,000 credits (up to 750 simulated calls and 10,000 live evaluations), and Premium is $1,000/month with 125,000 credits (up to 1,900 simulated calls and 25,000 live evaluations). Annual billing saves about 15%. Enterprise offers custom credit packages, regional compliance and dedicated support.

- **Automated conversation simulation:** Auto-generate test cases from your system prompt or define your own, then run hundreds of parallel simulated conversations with presets for accent, mood and goal.
- **Rubric-based evaluation:** Score every call against weighted, customisable criteria such as task completion, policy accuracy, sentiment, interruption handling and latency, with seven-day trend tracking.
- **Live production monitoring:** Every production call is silently logged and scored in real time, with alerts routed to Slack, email, PagerDuty, Opsgenie, Linear or webhooks when something drifts.
- **No-code platform integrations:** Connect Vapi, Retell or ElevenLabs agents in under five minutes using an API key, or route custom agents through the provided number and API.
- **Industry playbooks:** Hardware and industry templates for financial services, home services and real estate, including compliance, emergency-pathway and booking scenarios.

**Strengths:** Combines simulation, rubric-based evaluation and live monitoring in one platform.; Fast native integrations with Vapi, Retell and ElevenLabs using just an API key.; Rubric weighting and seven-day trend tracking turn voice agent quality into measurable numbers.; Alert routing to Slack, PagerDuty, Linear and webhooks fits existing on-call workflows.

**Limitations:** Pricing starts at $500/month, so it is a significant commitment for very small teams.; Native integrations currently center on Vapi, Retell and ElevenLabs; other platforms require the manual prompt-upload and call-routing workaround.; Evaluation quality still depends on how well you define your rubric and test cases.; Because it targets production voice agents, it is less relevant if you are only experimenting.
