Parallel agents
Run AI agents in parallel, and see every one of them.
RAPR AI is truly parallel: start a Claude session, a Gemini session and a Codex session without waiting for any of them, or split one big task into steps that run side by side. Kelvin brings a crew, one penguin per agent, so you can see who is working, who is waiting and who is done.
Kelvin, the RAPR AI penguin, shows what every agent is doing.
Independent sessions per AI, each with its own folder and history
/pipeline splits a big task into parallel waves with hand-offs between steps
“Call the Kelvin crew” turns a big prompt into a parallel pipeline
Each Kelvin wears its AI’s beanie colour and shows its real status
One task, many AIs
A planner AI splits the task into steps, assigns each to the best AI, runs independent steps at the same time and passes results to the steps that need them.
A crew you can read at a glance
The Kelvin crew groups steps into waves, shows waiting, working, done and failed steps, and celebrates when the whole crew finishes.
