# ASCII filter for OBS

The fastest **ASCII filter for OBS** is often a browser source: open TekDetek, build your look, add a Browser Source in OBS pointing at vikmil.com/tekdetek/, capture the tab. No OBS plugin to compile.
Free OBS output is watermarked and caps at 5 minutes per session (restart anytime). [Pro](https://tekdetek.gumroad.com/l/xkljia) removes the watermark and time cap.

## Free vs Pro

Free: open the app, swipe and edit looks (phone reaction-diffusion and cellular automata included), luma detection, Hand, watermarked MP4 or PNG up to 20 seconds, watermarked OBS up to 5 minutes (restart anytime).

Pro: clean export with no watermark, unlimited record and OBS, full preset library, Shuffle, Depth and Alt ASCII, add RD / CA / PreText / GEO 3D / Sonify on the desktop graph, higher detection caps. TekDetek is not completely free.
