Turn any PDF into a
hosted flipbook
— via API or MCP

Upload a PDF with a single HTTP POST. Get back a link your users click to instantly create a live, shareable Simplebooklet flipbook — complete with analytics and embed codes.

No SDK. No credit card. Free to use.

# one request
curl -X POST \
"…/api/api/upload" \
-F "file=@report.pdf"

simplebooklet.com/your-flipbook

your.pdf → live, flippable, shareable

Simple by design

How it works

Two API calls and your PDF is live on the web.

POST your PDF

Send a multipart POST /api/api/upload with your PDF file. Receive a JSON response containing a convert URL.

Return the link

Pass the convert URL back to your user — in a chat response, email, or wherever your app surfaces content. The link is ready immediately.

User clicks → flipbook

Your user opens the link, signs in or creates a free account, and the flipbook converts automatically — permanently hosted with a shareable public URL.

REST API

Two calls. No SDK required.

Works from any language or tool that can make an HTTP request.

1 — Upload your PDF

shell

curl -X POST \
  https://simplebooklet.com/api/api/upload \
  -F "file=@/path/to/your.pdf"

Response

json

{
  "status": "ok",
  "data": {
    "url": "https://simplebooklet.com/api/api/convert/a1b2c3d4e5f6"
  }
}

2 — Share the convert URL

python

import httpx

# upload
with open("report.pdf", "rb") as f:
  r = httpx.post(
    "https://simplebooklet.com/api/api/upload",
    files={"file": f}
  )

url = r.json()["data"]["url"]

# hand to user
print(f"Open to create your flipbook:\n{url}")

The convert URL is valid until the user completes signup. Append ?title=My+Title to pre-fill the flipbook name.

AI-native integration

Works natively with Claude and AI tools

Register the Simplebooklet MCP server once and Claude will know how to create flipbooks whenever you ask — from a public PDF URL, or from a PDF Claude generates itself.

HTTP MCP — Claude.ai & Claude Desktop

Add the Simplebooklet MCP server via Settings → Customize in claude.ai. Once connected, Claude gains two tools:

upload_simplebooklet — ask Claude to generate a PDF (a report, brochure, summary) and it uploads it directly — no public URL needed.
create_simplebooklet — give Claude a public PDF URL and it fetches and converts it into a flipbook.

{
  "mcpServers": {
    "simplebooklet": {
      "url": "https://louddoc.com/mcp"
    }
  }
}

Add to ~/.claude.json or your Claude Desktop / claude.ai MCP Settings → Customize using URL: https://louddoc.com/mcp

Claude discovers the API automatically via llms.txt and openapi.yaml at the Simplebooklet root — so even without the MCP you can point Claude at those files and it will know how to call the API.
