This multi-model video AI sends each scene to the frontier model that fits it best, drawing on Sora 2, Google VEO, Wan 2.5, Kling, and others. A photorealistic shot can come from one engine while cinematic motion comes from another, and the agent composites the result. New models get folded in as they launch, so you don't chase a second subscription to stay current.

The agent plans first. It names and times every scene, writes the script, and proposes the cast before anything renders. You can rewrite a line, replace a shot, or pick another voice, and the credit cost sits on the approve button so you know the price up front. This planning step is what separates a video agent from a one-prompt clip generator.

From 15-second TikTok ads to 30-minute training videos, the same agent covers UGC ads, TV commercials, animated stories, faceless stories, app promos, explainers, presentation videos, YouTube and TikTok videos, sales videos, and video restyling. As a UGC ad generator and AI commercial generator in one, it writes the script and storyboard for each format before it renders. Each format carries its own templates and workflow, so you pick the output type and the agent adapts.

The AI avatar generator library spans hundreds of presenters that can run up to 30 minutes, and the AI voice generator offers 400+ voices across 140+ languages with frame-accurate lip-sync. It matches mouth shapes to each language's phonemes, so a Spanish version shows Spanish lip shapes rather than an English mouth with a Spanish track.

Beyond full videos, the Studio generates images from 12 models and 30 ready-made looks, builds clips up to 30 seconds from a prompt or an image, and runs a voiceover studio with 20 narrators. Voiceovers and music never cost credits, which keeps the audio side cheap even on smaller plans.

Every plan includes the full agent, all 11 formats, and full commercial rights, with credits running from 3,500 a month on Starter to 30,000 and up on Max. AI video pricing here is credit-based rather than per render, so a light month costs less than a heavy one. Paid ads, client deliverables, broadcast placements, and monetized content are all covered with no royalties or per-video licensing fees. Yearly billing takes 30% off.

On the Agency plan, you connect TikTok, Instagram, and Facebook accounts and post or schedule finished videos from the app, and publishing never costs credits. The winning video ads library and competitor tracking let you follow rivals, browse their best-performing ads, and recreate any of them in a single click.
