About pencil.md

pencil.md is a free, open-source markdown publishing service. Paste
markdown, get a permanent shareable URL — no account, no signup, no paywall.

# How it works

Open the home page, type or paste markdown, click publish. You get a short
URL like pencil.md/abc12345. Share it anywhere. Your browser cookie marks
you as the owner so you can edit later. The same credential is also returned
by the public API as edit_token for stateless clients and AI agents.

# Why

• Free forever. No upsells.
• Open source (MIT). Self-hostable on Cloudflare Workers in minutes.
• No signup. Cookie-only ownership.
• AI-friendly. Free public API for agents to publish and update pages.
• Privacy-respecting. No third-party scripts, no analytics, no fonts from a CDN.
• Strict security. Sanitized markdown, layered XSS defense, signed cookies, HSTS-ready.

# Draw

Prefer an infinite canvas? draw.pencil.md lets you sketch, drop
shapes, and write live-markdown text anywhere on the page — then save and share
it just like a markdown page.

# Good for

Long-form notes, drafts, change-logs, post-mortems, quick docs, public
artifacts from AI agents — anything you’d post on a gist with friendlier
rendering.
