Which one should you pick?
Pick Aegisub if
You’re building around post-production subtitle work with precise timing and ass karaoke styling. Aegisub is the canonical open-source subtitle editor and still the right tool for ASS work — karaoke timing, fansub-grade styling, frame-accurate adjustments. The official repo woke up again in 2026 after years of slow activity, with portable 3.
Pick Zubtitle if
You’re building around social marketers. Zubtitle is the boring-good tool you'd pick when you already have a clip and just need captions, a headline, and a square crop without thinking about it. There's no 'AI finds your viral moment' magic, which is honestly refreshing.
