The audio benchmark grew into a serious agents platform with a testing framework bigger vendors lack — just watch the shared credit meter, overages bite without warning.
Element scores
Strengths
Best-in-class audio across the board — Eleven v3 TTS out of alpha (02/2026), Scribe v2 STT, Music v2, Dubbing v2 — with G2's independent natural-voice score placing it ahead of Google Cloud TTS. The Agents platform is the surprise: hosted RAG, mature tool calling with MCP support, agent transfers, and an evaluation/testing framework (scenario, tool-call, simulation, probabilistic runs) that most bigger platforms don't match. Momentum is official: $500M Series D at $11B (02/2026), $350M→$500M+ ARR in four months.
Honest dings
Billing is the documented sore spot: Trustpilot sits at ~3.0/5 (~1,005 reviews) driven almost entirely by billing complaints — automatic overages on Creator+ hit without real-time alerts, and one shared credit pool means a minute of music (900 credits) or dubbing (up to 10,000 credits/min) silently eats your TTS budget. The free tier carries no commercial license. No first-party LLM means agent reasoning quality is inherited, and voice cloning remains a misuse surface despite verification gates.
