Introducing

The AI-native workspace
for knowledge work

A local-first operating system where agents run in the background and users can build anything. Your files. Your computer. Your data.

The problem

Knowledge work is fragmented,
and nothing is built for agents

01

Fragmentation

People use 10+ apps and copy-paste between them. Nothing unifies their work.

02

No agent-ready tools

Claude Code is incredibly powerful, but people are using it in interfaces that weren't built for it. Obsidian is close but sucks for collaboration and real work. Notion has agents but no fine-grained control.

03

The SaaS apocalypse

People are vibe-coding replacements for the apps they pay for. But they have nowhere to do this properly.

The thesis

Back to raw elements

We're moving away from bloated databases and complex apps, back to the original Lego blocks — small files, HTML, markdown. AI is good enough to work with them now. Agents work incredibly well with simple files.

The incumbents — Notion, Microsoft, Google — can't adapt. Too much infrastructure. Too much bloat. The agentic revolution needs a new foundation.

The solution

What Calyx does

All your work, one place

Projects, tasks, writing, presentations, code, reports. Local-first — your files, your computer.

Built on VS Code

A full IDE with a terminal. Handles all file types. Bring your own agent — Claude Code, Codex, Open Code, whatever.

Background agents

Not just a sidebar chat. Create agents with dedicated skills for specific tasks. They run automatically — auto-respond to support, generate reports, monitor your inbox.

Build anything inside it

Vibe code applications. Create custom interfaces and plugins. Connect to any tool via API. The workspace is the platform.

Why now

The agent revolution

Claude Code, Codex, and coding agents are here and absurdly capable. They can do far more than code.

The subsidy wave

AI companies are subsidizing compute massively. A max subscription gets an order of magnitude more value per dollar.

SaaS replacement

People are vibe-coding replacements for every app they pay for. They need a workspace to do it in.

Back to files

The industry is moving back to simple files that agents can work with. The timing is perfect for local-first.

Positioning

What exists today doesn't work

Notion

Bloated, not local-first

Obsidian

Just notes, no real work

Cursor

IDE-only, not a workspace

Calyx

Everything, agent-native, local-first

Business model

Primary

Subscription

Monthly access, per-seat for teams

Growth

AI credits

Built-in agent harness, users pay for their own compute

Ecosystem

Plugin marketplace

Users build and monetize plugins. Revenue share.

Go to market

Content-led, not ad-driven

Every Notion ambassador and "AI ops person" at companies already feels this pain. Targeted outreach to the people who are already searching for this.

Plus a suite of free tools — a markdown-to-blog publisher, a documentation site generator, a mini presentation tool — each one useful on its own, each driving awareness back to Calyx.
