What it does

Chat is great for Q&A, but real work isn’t linear. Spine Canvas is an unlimited visual workspace for AI that lets you orchestrate 300+ models with a single subscription. Think in blocks (Chat, Deep Research, Apps, Memo, Image, Slides), branch safely, run in parallel, and keep explicit context across everything — all in one collaborative canvas.

Spine AI builds Canvas for cloud-based multi-agent work and Medley for local-first agent orchestration, backed by research into adaptive agent systems.

Spine AI plans, delegates, reviews, and repairs complex work across many agents. Use Canvas in the cloud, or run Medley locally through the tools you already trust. Canvas assembles specialized agents across 300+ models to research, analyze, and produce sourced deliverables, websites, and apps. Canvas is SOC 2 Type I compliant. Medley returns finished work within your constraints and permission boundaries, with the full history of evolving plans, adaptive graphs, and execution receipts behind it. Its local daemon and Claude Code or Codex plugins coordinate models and worker harnesses across research, analysis, software, and more. Both products grow the work graph as agents discover…from getspine.ai

  • Trickle - Magic Canvas 2025 · trickle.so · ▲1,064

    Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

    Hey everyone, I've been hacking on this idea with a friend as we've been using chatgpt and other AI tools in our day to day work and find ourselves copy/pasting to each other frequently. We often share chatgpt links with each other, but it's been frustrating that they are read-only and we can't pickup the conversation or both talk to an LLM with shared context. We built a shared chatroom to explore what it'd be like to talk with multiple LLMs and humans in the same chat, and so far it feels pretty cool, but we're curious if anyone else would find it useful as well. Right now you can: -…
