Full Comparison

Criterion Arcads Simli
Starting price Not stated Free plan; paid use is pay as you go The free plan carries $10 of credit on signup and a monthly top-up of 50 minutes. Paid use is billed as you go with volume discounts; Simli does not publish a per-minute rate on its site, and the pricing detail sits behind a sign-in in the app.
Free trial Three-day trial; the saved card is charged for the Starter plan unless it is cancelled inside 72 hours Free plan with $10 of credit on signup and a monthly top-up of 50 minutes
Output Short UGC-style ad videos performed by AI actors Real-time lip-synced video avatars streamed over WebRTC
API Yes, an AI video API, a separate lip sync API and a hosted MCP server at mcp.arcads.ai Yes, the product is an API

Custom and cloned avatars Yes, generated faces that can be made to hold a product, show an app or wear specific clothes Yes, upload a face image in the web app; processing takes a couple of hours
Languages and translation Yes, translation into 30+ languages No list of its own.

Editor Partly: ad presets for performance marketing, emotion control, background removal and a workflow builder; one-click B-roll, music, captions and transitions is announced as coming No, there is no video editor: faces are created in the web app and driven from your own application code

The trade-offs

Strengths and Limitations

Arcads

Strengths

  • Large library of 1,000+ AI actors
  • Generated actors can hold a product, show an app or wear specific clothes
  • Several third-party video models available in one place, including Seedance 2.5, Kling and Sora 2 Pro
  • AI video API and a separate lip sync API for automating ad production
  • Hosted MCP server, so an AI assistant can generate ads directly

Limitations

  • 30+ languages, fewer than the broad avatar platforms offer
  • The one-click editor for B-roll, music, captions and transitions is announced but not yet shipped
  • Built for short direct-response ads, so it is a poor fit for training or explainer video
  • No learning features

Simli

Strengths

  • Under 300 milliseconds of added latency, so the face keeps up with a live conversation
  • Open-source plugins for LiveKit Agents and Pipecat, plus JavaScript and Python SDKs
  • Free plan with signup credit and a monthly minute top-up

Limitations

  • Renders the face only: speech, language model and voice come from your own stack
  • No editor and no finished video files, so it needs engineering work
  • Custom avatar processing takes a couple of hours

Plans
