Markdown publishing for
people and AI agents.

RenderMark turns Markdown into polished PDFs, Word docs, Google Docs, HTML pages, live previews, images, and visual diffs.Use it in the browser, from GitHub, through the REST API, or directly inside MCP-compatible agents.

How it works

  1. 1

    Paste, upload, import from GitHub, or let an agent send Markdown

  2. 2

    Render, validate, template, theme, and preview the document

  3. 3

    Publish, share, sync, email-restrict, or export in the format you need

Choose how to use RenderMark

Give your agent RenderMark workflow guidance, start in the browser, connect through MCP, call the REST API, or use the CLI when MCP is unavailable.

Agent Skill

Workflow instructions only
View on GitHub

Adds RenderMark workflow instructions to compatible agents. Connect hosted or local MCP separately when the agent needs RenderMark tools.

Tell your agent

Please read the README, then fully install RenderMark for this agent using the documented setup for this surface: https://github.com/jmsaavedra/rendermark-agents

Example requests

  • Publish README.md to RenderMark and return the share link.
  • Validate docs/launch.md, fix any blocking Markdown issues, then publish it.
  • Export docs/guide.md to a PDF with the serif theme and return the saved path.

Browser app

No install required
Try demo

Paste, upload, or import Markdown, then preview, export, publish, and share it from any modern browser. Best for people and browser-capable agents.

Hosted remote MCP

https://mcp.rendermark.app/mcp
Connection guide

Recommended for hosted pages, share links, live previews, validation, and document management. Add this Streamable HTTP endpoint and complete OAuth when prompted; no local process is required.

Local MCP server

npx -y @rendermark/mcp-server@latest
Setup guide

Use this command in a stdio MCP client for all 17 tools, including filesystem exports, batch jobs, images, visual diffs, Google Docs, and local credential setup. PDF and image rendering require local Chrome or Browserless.

No MCP support? Use the CLI fallback

REST API

https://rendermark.app/api/v1
API quickstart

Use a Bearer API key from scripts or systems that prefer HTTP. Create and manage documents, shares, collections, embeds, revisions, and GitHub sync.

Built for people who actually use Markdown

If your content starts in Markdown—whether from GitHub, ChatGPT, Claude, Codex, Cursor, or your own editor—RenderMark turns it into a real document you can share with anyone.

Product Managers

Sharing specs with non-technical stakeholders

Developers

Publishing READMEs and RFCs outside GitHub

AI Agents

Rendering, validating, publishing, and sharing Markdown through MCP tools

Consultants

Sending proposals and reports to clients

Builders & Founders

Sending docs to partners and stakeholders outside GitHub

Students & Educators

Sharing formatted notes, assignments, and guides

Everything Markdown needs after writing

RenderMark covers the whole handoff: from raw Markdown to polished artifacts, hosted pages, synced docs, and agent-accessible workflows.

Import anywhere

Paste Markdown, upload .md files, import public or private GitHub content, or send content through the REST API or MCP.

Rich rendering

Clean typography with themes, templates, tables, task lists, callouts, wiki links, Mermaid diagrams, KaTeX math, and syntax highlighting.

Publish and share

Create permanent public links, temporary live previews, email-restricted shares, table-of-contents pages, and social preview images.

Agent tool surface

Hosted MCP exposes remote-safe render, validate, publish, preview, read, update, list, share, delete, and GitHub sync tools.

Local export power

The local MCP package adds PDF, DOCX, HTML, image, batch export, visual diff, Google Docs publishing, and setup helpers.

GitHub sync

Import from a repo, resolve relative assets, preserve GitHub context, and auto-update published docs when Markdown changes.

Why RenderMark exists

Most documentation tools are built for teams, workspaces, and long-term knowledge bases. RenderMark is built for the moment when you already have a Markdown file and just need to share it.

Other tools

  • Require setting up a workspace or doc system
  • Force you into a new editor
  • Leave agents to stitch together export and hosting flows
  • Overkill for one-off documents and generated Markdown

RenderMarkRenderMark

  • Paste or import Markdown from
  • Browser, REST API, CLI, hosted MCP, and local MCP access
  • Share links, live previews, email access, file exports, images, and visual diffs
  • Clear tool boundaries for rendering, publishing, syncing, and deletion

Frequently asked questions

How does RenderMark work?▼

RenderMark turns Markdown into polished documents from multiple entry points:

  1. Import your content — Paste Markdown directly, upload a .md file, import from GitHub, call the REST API, use the CLI, or connect through MCP
  2. Render instantly — Your document gets clean typography, themes, templates, diagrams, math, code highlighting, and an optional table of contents
  3. Share or export — Publish a link, create a live preview, share by email, sync from GitHub, or export in the format you need

If you import from GitHub, you can enable sync to automatically update your published document whenever you push changes to your repo.

How can agents access RenderMark?▼

Use hosted remote MCP when the client supports Streamable HTTP. Add https://mcp.rendermark.app/mcp and complete OAuth when prompted. This is the simplest provider-neutral connection.

Use the local @rendermark/mcp-server package over stdio when the agent must save files, batch export, render images or diffs, publish to Google Docs, or use local credentials.

Use the rendermark CLI as a fallback when an agent has shell access but cannot use MCP. It supports PDF, DOCX, and HTML export plus hosted publishing.

The optional Agent Skill is a portable folder containing SKILL.md. It gives a compatible agent RenderMark-specific instructions, but it does not connect the agent by itself. Give the agent the install prompt above so it can choose the correct provider-specific method.

The public rendermark-agents setup repo is the canonical source for current provider-specific MCP, skill, and plugin instructions.

What formats can RenderMark export to?▼

Available output depends on the surface you choose:

  • Browser app — PDF, Word, HTML, Google Docs, and published links
  • Hosted MCP — Styled HTML, temporary previews, persistent links, and document management
  • Local MCP — PDF, Word, HTML, PNG/JPEG, batch export, visual diffs, Google Docs, and hosted links
  • CLI — PDF, Word, HTML, and hosted publishing when MCP is unavailable
  • REST API — Document, sharing, collection, revision, embed, and GitHub-sync workflows

Can I use RenderMark with GitHub?▼

Yes. Import Markdown from any repo (even private ones) and optionally enable sync to auto-update your published doc whenever you push to GitHub.

Learn how to import Markdown from GitHub →

What Markdown syntax does RenderMark support?▼

The renderer supports an optional table of contents, headings, lists, tables, task lists, callouts, code blocks with syntax highlighting, images, blockquotes, Mermaid diagrams, KaTeX math, wiki links, and inline formatting. Exact output can vary by export format.

See the full Markdown syntax guide →

Do I need to install anything?▼

No install is required for the browser app or hosted remote MCP endpoint. Configure the local MCP package when an agent needs the complete tool set, or install it globally for the CLI fallback. Agent Skill installation is optional; give the agent the provider-neutral install prompt above.

Can I use RenderMark with AI-generated Markdown?▼

Yes. Paste output from ChatGPT or other AI tools, or let an MCP-compatible agent call RenderMark directly to validate, render, publish, share, update, sync, and manage documents.

Is RenderMark free?▼

Yes. You can create and export documents for free. Upgrade to Pro for unlimited exports and link publishing.

Is my data private?▼

Yes. Your documents are not public unless you publish or share them. Hosted MCP uses per-user OAuth or API-key credentials, and remote tools are scoped for explicit document operations.
