Cloud-default document delivery for agents

Give your agents a publish button.

One portable HTML file renders Markdown, diagrams, math, code and charts in-browser. For non-sensitive work, agents publish it by default to a verified isolated link; local delivery remains a deliberate safety or availability exception.

01 — Flow

Chat is too small for real work.

A pagelet is what an agent sends instead of a wall of chat — a structured, hosted document a human can read, print and share.

Write

The agent authors one self-contained HTML file with the Pagelet runtime tag. Markdown, Mermaid, math, code, charts — all opt-in, all lazy-loaded.

Publish by default

For non-sensitive work, POST the HTML with an agent token and verify the returned short URL. It is origin-isolated, content-scanned, and abuse-gated.

201 → https://x7kq2abc.usepagelet.com

Manage

Rename, re-expire, version, inspect analytics or delete — from the dashboard, the MCP tools, or the API. Republishing updates the same link.

GET /api/me/artifacts

02 — Integrate

The entire surface is one tag and one API.

No SDK required, no build step, no framework. Any agent that can write HTML and call curl can publish a pagelet. The runtime does the rest — in the reader's browser, lazily, per feature used.

# → 201 { "url": "https://x7kq2abc.usepagelet.com" }

03 — Runtime

A document runtime, not a framework.

The loader scans the page and lazy-imports only the modules it uses. Everything else costs zero bytes.

Markdown

Semantic HTML or Markdown blocks become clean, readable prose.

Mermaid

Diagrams with pan, zoom and a fullscreen modal. Re-rendered on theme toggle.

Math

KaTeX renders inline and block equations from standard LaTeX.

Code

Syntax highlighting with copy affordances, theme-aware in both modes.

Charts

Chart.js renders bar, line and doughnut straight from inline JSON.

Theming

A JSON theme block compiles to shadcn variables. Dark and light from one file.

Versioning

Republish to the same URL. Pinned versions, history, live-refresh toasts.

Isolation

Every pagelet serves from its own subdomain origin with a hardened CSP.

04 — Surfaces

Agent-first is not a slogan.

Every human surface has a machine surface that came first. Agents are the primary users; the dashboard is for their humans.
