spatial conversation engine

træk — follow ideas, not threads.

Every answer opens more questions. Give them space.

Something always gets lost in the scroll.

A good idea came up three replies ago. You scrolled past it. Two paths split. You had to choose. That's not a conversation — that's a log.

The more complex the thinking, the worse a single thread represents it.

If AI thinking branches, your UI shouldn’t stay flat.

possible paths

Not an edge case. Not an afterthought.
Branching is the default.

A map, not a log.

Every message is a place. Every reply, a direction. Pan the canvas. Follow a thread. Branch into the question you almost didn't ask.

  • Branch anywhere — reply from any node; each path stays intact.
  • Spatial layout — ideas spread out instead of stacking up.
  • Thought nodes — reasoning stays visible without cluttering the path.
  • Live streaming — watch tokens land in place as the model thinks.
Two components. That's it.
npm install traek

<script lang="ts">
  import {
    TraekCanvas,
    TraekEngine,
    DEFAULT_TRACK_ENGINE_CONFIG
  } from 'traek';

  const engine = new TraekEngine(DEFAULT_TRACK_ENGINE_CONFIG);

  // Canvas calls this with the text the user typed
  // and the node they're replying from (for branching).
  function onSendMessage(input, fromNode) {
    const userNode = engine.addNode(input, 'user', {
      parentIds: fromNode?.id ? [fromNode.id] : []
    });

    const assistantNode = engine.addNode('', 'assistant', {
      // Parent defaults to the active node (the new user message),
      // so replies naturally branch from the message you answered.
      autofocus: true
    });

    // stream chunks into assistantNode.content here...
  }

  <TraekCanvas {engine} {onSendMessage} />
</script>

Two layers. Your rules.

træk keeps the graph and the UI separate — so you stay in control:

  • TraekEngine — nodes, relationships, layout, and state.
  • TraekCanvas — the spatial UI, pan/zoom, and interaction.

Bring your model, your streaming, your persistence. træk keeps everything navigable.

Made for when AI thinks out loud.

  • agents with memory
  • prompts worth exploring
  • reasoning that branches
  • multi-path generation

Start in minutes.

Use TraekCanvas as your full UI — or wire TraekEngine into your own components and render messages your way.

Ideas deserve more space than a scroll.

træk is actively growing. Drop it in, explore the demos, and help shape what spatial AI conversation can be.
