twitch2x

twitch2x enhances Twitch live streams in real time using your GPU.

It captures each video frame, runs it through a small neural-network upscaler that adds detail and reduces compression artifacts, and paints the result

back over the player. The whole pipeline runs locally inside your browser on WebGPU. Nothing is uploaded, no servers are involved, no data is collected.

The extension was built because Twitch's source bitrate is capped — even on 1080p60 channels you can see banding in dark scenes, mosquito noise around HUD

text, and softness in fast motion. twitch2x doesn't recover what the encoder threw away (nothing can), but it cleans the artifacts and produces a

noticeably sharper image, particularly on game streams with crisp UI overlays.
