Key bets: referral loop, AI writing assistant, team collaboration.

Linear docs bury your best thinking.

Notes apps, whiteboards, AI agents, task managers, all scattered across a dozen tabs. Over time, context disappears and ideas start to fade away.

Cobloc is a spatial workspace where everything lives on one canvas. Notes, tasks, links, documents, and AI agents.

Built for teams brainstorming their next product, students organizing research, creatives building moodboards, or anyone who thinks better when ideas have room to breathe.

Got questions?

If you can't find what you're looking for, get in touch.

Getting started

Cobloc is a spatial workspace where you arrange blocks — notes, todos, links, images, AI chat, and more — on an infinite canvas. Think of it as a whiteboard that's as powerful as a document editor.

Sign up for free, create your workspace, and start adding blocks to your first canvas page. No credit card required.

Yes! Cobloc is free for personal use with unlimited pages. Upgrade to Pro for unlimited blocks and full AI model access.

Features

Cobloc integrates with Claude (Anthropic), Gemini (Google), and GPT-4o (OpenAI). You can switch between models mid-conversation and branch conversations to explore different ideas.

Yes! With the Team plan, you can invite collaborators to your workspace. Real-time presence, @mentions in todos, and shared projects make teamwork seamless.

Other questions

Your data is stored securely with end-to-end encryption in transit. We use Convex as our real-time database with built-in authentication and access controls.

Import features are on our roadmap. In the meantime, you can paste content directly into note blocks with full formatting preserved.
