Studio-grade AI text to speech and voice cloning
Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing].
Create a usable voice clone from a short audio sample and reuse it across scripts and languages.
Browse and use a large catalog of community voices covering many languages and character styles.
Transcribe audio with multilingual support and emotion or speaker cues for downstream editing.
AI governance, testing, and observability for regulated enterprises
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
