onPanda - Inspect and steer LLMs and agents at the token level

onPanda is an open-source interface for inspecting and steering LLMs and agents at the token level. Select a generated token, inspect alternatives, replace it or edit freely, then continue generation from that point. Branch generations, inspect reasoning and tool calls, and annotate model and agent trajectories in one interactive workspace.
