Frequently Asked Questions
Is Aegisub still being developed?
Aegisub had minimal updates for years after 2014. There was a brief revival in 2024, but development remains sporadic. For a tool you'll use daily, actively maintained alternatives are recommended.
Can I import my Aegisub projects into Diwadi?
Yes, Diwadi supports ASS and SSA files natively. Simply open your Aegisub project files directly - all styling, timing, and karaoke effects are preserved.
Which alternative has the best karaoke support?
Subtitle Edit offers karaoke in its free version. Diwadi supports ASS karaoke features (\k, \K, \kf, \ko) on Plus subscription. Both have modern interfaces for editing these effects.
Do I need to be online to use these alternatives?
Subtitle Edit and Gaupol work completely offline. Diwadi offers Cloud AI (requires internet) or Local AI (works offline). Kapwing and Amara require internet as they're cloud-based.
What about Crunchyroll's move away from Aegisub?
In 2025, Crunchyroll reportedly forced staff to switch from Aegisub to cloud-based OOONA. This highlights the industry shift toward modern tools - though Diwadi offers modern features without the cloud requirement.
Which alternative is best for anime fansubbing?
Subtitle Edit is free with full ASS karaoke support. Diwadi Plus also supports advanced karaoke and effects with a more modern interface. Both handle complex typesetting well.
Can I do batch subtitle processing?
Diwadi and Subtitle Edit both support batch operations. You can apply timing shifts, find/replace text, or convert formats across multiple files.
What about mobile subtitle editing?
None of these desktop alternatives have mobile versions. For mobile, you'd need cloud tools like Kapwing, though with privacy trade-offs. Most professional subtitle work is done on desktop.
