Synthesys
AI video agent that routes your brief to the best model for the job
Overview
Synthesys positions itself as a video agent rather than a single video generator. Feed it a prompt, a product URL, or even a document, and it writes the script, then routes the actual generation to whichever underlying model (Sora 2, Google VEO, Kling, Wan 2.5) suits the format best. On top of that it has its own library of over 1,000 AI avatars and 400+ voices, so you're not always relying on third-party models for the talking-head parts.
It's aimed squarely at marketing teams and agencies who need to produce a lot of video variations fast, think UGC-style ads, product demos, and training content, rather than a single cinematic piece. Credits are the currency across every plan, and they get eaten up quickly if you're generating with the higher-end video models, so the advertised entry price is more of a floor than what a busy team will actually pay. Commercial rights are included on every tier, which is a genuine plus for agencies reselling the output to clients.

Pros
Access To Frontier Models: One subscription taps Sora 2, VEO, and Kling instead of paying for each separately.
Large Avatar And Voice Library: 1,000+ avatars and 400+ voices across 140+ languages.
Commercial Rights Included: No extra licensing cost to use output commercially, even on the cheapest tier.
Format Variety: Templates cover ads, explainers, and training video, not just one style.
Cons
Credit System Punishes Volume: Heavier models burn through monthly credits fast, so real usage often costs more than the sticker price suggests.
1080p Cap On Lower Tiers: 4K export is locked to the Agency plan.
Single Seat On Entry Plans: Indie and Studio only include one user seat, which limits small team collaboration.
What Makes It Unique
Model Routing: Instead of locking you into one video engine, Synthesys picks between Sora 2, VEO, Kling, and Wan 2.5 depending on the brief.
