Editor's Review
Editor's Review (February 2026)
Synthesia remains the enterprise gold standard. The Expressive Model 4.0 with micro-expression technology produces the most natural-looking avatars in the industry. AI Playground integrating Veo 3.1 and Sora 2 for B-roll is a smart addition.

What Could Be Better:

• Per-credit pricing model makes costs less predictable for high-volume users
