What NekoCap does

A captioning toolkit that respects the player you're already in.

Say goodbye to re-uploads! Captions float over the original video and they're written by humans who love the content as much as you!

Captions in-player

Install the extension, open a video, pick a caption from the dropdown below the player.

Advanced effects

Renders Advanced Substation Alpha (SSA/ASS), with karaoke timing, fades, positioning, and custom fonts. Good for music videos, anime, and fan-typeset releases.
View supported custom fonts

愛を伝えたい

Convenient editor

Time and translate from inside the player. Hotkeys for cue boundaries, with custom positioning, colors and instant preview. Submit or export to SRT when you're done.
