The Pulser toolkit
Built around the moments that interrupt a stream.
Three focused tools handle chat, stream control and screenshots without turning Pulser into another crowded dashboard.
Pulser Voice
Trigger OBS actions and Pulser commands with your voice while your hands stay on the game.
Pulser Images
Capture screenshots by hotkey, voice or Pulser itself without leaving your game or breaking the flow of your stream.
AI Chat Bot
Chat that feels part of the stream.
Give the bot a personality, recent chat context and clear response rules. It can reply to mentions and questions, or join a conversation occasionally without taking over chat.
✓Custom personality and stream context
✓Mentions, replies, questions and cooldowns
✓Your own supported AI provider API key
Pulser Voice
Your voice becomes a stream control.
Create phrases for the actions you use every stream. Switch OBS scenes, control sources and trigger Pulser actions without reaching for another window.
✓Custom trigger phrases
✓OBS WebSocket actions
✓Recognition controls and command cooldowns
Pulser Images
Save the moment without leaving it.
Capture while your game stays front and centre. Use a global hotkey, a voice phrase or Pulser, then manage recent captures from the app.

One streamer toolkit
Stay in the game. Pulser handles the small stuff.
Keep the tools you use during a stream in one place, let enabled features run in the background, and spend less time tabbing between utilities.
