ASCII webcam filter online
An ASCII webcam filter online turns live camera video into a readable glyph field — brightness mapped to characters, palette from ember to terminal green. TekDetek runs it in the browser with no plugin.
Open the app, allow camera, swipe an ASCII look. Free export is watermarked and 20 seconds. Pro is clean and unlimited.

How it differs from phone ASCII apps
Most ASCII webcam filters are single-style phone apps. TekDetek is a node graph: stack detection, reaction-diffusion, or overlay after ASCII. Send the tab to OBS as a browser source — see ASCII filter for OBS.
