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 AutoCap if
You’re building around mobile creators. AutoCap is the cheap phone captioner you'd hand to someone who films their own clips on an iPhone and just wants captions, not a workflow. Five bucks a month, no watermark, decent fonts.
