Criterion D-ID Simli

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.
