Agentic ad production OS that analyzes, builds, and runs creative across every major platform
Airpost continuously audits the ads running on Meta, TikTok, YouTube, Google Display, AppLovin, LinkedIn, Snap, Pinterest and connected TV so you always know what is live and what is working.
The platform generates video and static ads to each placement's spec, including 9:16, 1:1 and 16:9 formats, drawing on proven campaign signals rather than generic templates.
Every generated ad comes with the reason it was produced, so reviewers understand the strategy behind each asset before approving it.
Your brand and compliance checks are applied to every asset, and AI-generated people or footage are only used when you explicitly allow them.
AI that edits your video like a professional editor would
Pick a visual style and Captions cuts scenes, adds zooms, overlays B-roll and music, and returns a fully edited video in one pass.
Generate animated word-level captions with stylized fonts, or translate and subtitle content in more than 100 languages.
Create a digital twin or choose from a library of ready-made avatars, then reuse the same presenter across topics with prompt-based changes to outfits and backdrops.
Direct changes with simple text prompts, so beginners can make advanced edits without knowing a timeline editor.
