Spine Canvas - Go beyond chat & collaborate visually across 300+ AI models

👋 Hey Product Hunt!

We’re Akshay and Ashwin, co-founders of Spine AI (YC S23) — and we’re thrilled to introduce Spine Canvas, our biggest update yet.

Chat is great for Q&A, but real work isn’t linear. Most AI tools trap thinking in a single thread where context disappears, branching is impossible, and switching between models or apps breaks your flow.

Spine Canvas is an unlimited visual workspace for AI — a place where you can orchestrate 300+ models with a single subscription, think in blocks (Chat, Deep Research, Memo, Image, Slides), branch safely, run in parallel, and keep explicit context across everything you build.

💡 What You Can Do in Canvas

Orchestrate 300+ Models in One Place: GPT-5.1, Claude 4.5, Gemini 3, Kimi, Flux, Nano Banana, and more — pick the right model per step and switch mid-flow without losing context.

Think in Blocks, Not Threads: Chat, Deep Research, Apps, Image, Slides, Prompt, Memo, Tables — each block has an explicit role, and blocks connect seamlessly, so workflows stay modular, interpretable, and collaborative.

Organize and (explicitly) utilize all your content in a single workspace: Paste or drag in PDFs, YouTube links, webpages, or even past LLM chats. Wire them directly into your workflow with full visibility and control.

Branch, Run, and Evolve: Explore alternatives safely, run tasks in parallel, and re-run updates that cascade through connected branches automatically.

🧠 What Users Are Currently Using Canvas For

• Market deep-dives that flow into competitor profiles, battlecards, and executive memos.

• Content engines that turn one idea into dozens of platform-ready assets.

• Founder and product strategy rooms combining interviews, insights, and launch plans.

• Creative labs exploring visual directions and brand systems.

• Interactive prototyping to generate wireframes, landing pages, and learning apps right alongside your research and docs.

• Student workspaces that synthesize lectures, papers, and videos into study guides and interactive quizzes.

💬 Why It Matters

Spine Canvas gives you:
Transparency — see exactly what each block knows.
Control — direct sources by domain, type, or date.
Speed — complex, multi‑step work finishes in minutes, not days.
Flexibility — model-agnostic orchestration keeps your workflow future-proof.
Completeness — go from research to memos, images, and slides, all in one workspace.

Chat works for Q&A. Canvas is for thinking & creation.

As a digital marketer, I'm always adapting to content needs. New products, new features, new messaging. Spine Canvas is my cheat code. I can run 10 versions of a campaign in parallel via one new prompt, pass context between branches, and quickly have context ready content for platforms like LinkedIn and X. It removes 90% of the copy-pasting and context-reset pain with ChatGPT. Thank you Spine :)

As an engineer on the team, what excites me most about Spine Canvas is how well it supports real technical workflows. Architecture work is never linear you’re evaluating patterns, exploring alternative system designs, comparing models, and keeping multiple layers of context (requirements, constraints, docs, traces) aligned.

Canvas finally gives me a visual workspace to map architectures, branch into different implementation paths, test reasoning across models, and link research, specs, and diagrams together. Being able to run parallel flows and re-use context across blocks has genuinely improved how I design and iterate on systems.

Can’t wait to see how other engineers use it for architecture, research, and multi-model workflows. 🚀

As an engineer, I mostly use Spine Canvas just as a regular user who often doesn’t know the exact steps to start with.

For open-ended tasks—writing blogs, brainstorming engineering problems, exploring the best trading algos, or even doing fun stuff like making a comic-style breakdown of the upcoming Marvel movie Doomsday— Spine Canvas has become my default place to think. Instead of bouncing between tabs and search results, I just drop everything onto a canvas and let it pull in what I need, so I can work through it all in one place. It makes research-heavy work feel a lot less tiring and a lot more structured.

What I love most is how context works here. Because it’s a canvas and not just a linear chat, I can throw in notes, links, docs, ideas—whatever—and different blocks can share and reuse that context. I don’t have to worry about the AI forgetting what we were doing; the canvas itself is the memory.

On top of that, from the same space I can generate high-quality images, spin up presentations, or even build some great apps on the go. As someone helping build it, it’s been really fun to see how much it already improves my own workflow, and I’m genuinely excited to see where we take Spine Canvas next.

Congratulations on the launch! Best wishes for the spine team

🚀 We’re excited to launch Spine Canvas!

Spine AI is an infinite thinking and creation canvas powered by 300+ AI models. Every model becomes a block — chat, text, lists, deep research, image generation, slide generation, app generation across models like Gemini 3, and more. You can pass context between blocks, branch ideas, and run them in parallel.

Instead of juggling Google Docs, Notion, tabs of different LLMs, and scattered design tools, you get one workspace where thinking → exploration → creation happens seamlessly.

Also here are some power user shortcuts and tips:

1. Copy paste public ChatGPT, Gemini or Grok links into the canvas and watch the ✨

2. Use https://app.getspine.ai/new for a new canvas

3. Double click anywhere on the canvas to add a new block

4. Drag and drop files anywhere directly onto the canvas

As a former researcher, I’ve loved the control and transparency the cavas gives me over the sources I want to use.

But I find myself using it the most for learning new skills. One of my favorite tricks: using chat to find relevant YouTube tutorials for a new subject, adding the most popular ones to the canvas, and chatting with them to figure out which is the most useful for what I’m focused on. Fantastic for avoiding long tutorials that aren’t actually that relevant.

Can’t wait to see more of what the community comes up with.

Really awesome work, team! Love the vision

Big fan of the block-based approach. Makes real workflows way easier to manage. Congrats on the launch!

Congratulations on the launch! It's a very smart product, and I see it being very useful.
