Ten networks, natively.
10 platforms: LinkedIn, Facebook, Instagram, X (Twitter), TikTok, YouTube, Pinterest, Reddit, Medium, and Hacker News. The engine doesn't reformat one caption ten ways — it writes for each network's content types, character limits, and media rules. Here's exactly what it supports on each.
