ArtiGram

Post, update and search AI-made artifacts (HTML, React, SVG, Markdown, Mermaid) on ArtiGram, a Reddit-style community for things built with Claude and ChatGPT. Tools: post_artifact, update_artifact, search_artifacts, list_communities. Search works without a key; posting uses a free API key from your ArtiGram settings.

Documentation

Post straight from your assistant

Add ArtiGram once as a connector. After that you just say "post this on ArtiGram in a/tools" and the artifact goes live, with the link back in the chat. Asking for a new version updates the same post.

1. Get your connector URL

Sign in, then create a key in Settings. You get a personal connector URL.

Clients that support custom headers can also use https://artigram.cafeboon.com/mcp with Authorization: Bearer <key>.

2a. Claude

  1. Open Claude, go to Settings and then Connectors.
  2. Choose to add a custom connector, name it ArtiGram and paste your URL. No other sign-in is needed.
  3. In a chat with an artifact, ask Claude to post it on ArtiGram.

2b. ChatGPT

  1. Open ChatGPT settings, then Apps & Connectors, and turn on developer mode under Advanced.
  2. Create a connector named ArtiGram with your URL and no authentication.
  3. In a chat, enable ArtiGram from the tools menu and ask it to post your canvas.

Scripts and the API

The same key works as a Bearer token for scripts on your own computer or server, for example a scheduled job. Create a post once, then publish new versions to the same post whenever you like.

curl -X POST https://artigram.cafeboon.com/api/v1/posts \
  -H "Authorization: Bearer $ARTIGRAM_KEY" \
  -F title="Election results, weekly" -F community=politics \
  -F source=claude -F file=@page.html

curl -X PUT https://artigram.cafeboon.com/api/v1/posts/POST_ID \
  -H "Authorization: Bearer $ARTIGRAM_KEY" \
  -F note="Week 42" -F file=@page.html

JSON works too: {"title", "community", "code", "kind", "description", "source"}. Responses include the post id and url.

What runs on ArtiGram

  • Complete HTML pages, including scripts, fonts and libraries from CDNs.
  • React components as Claude and ChatGPT write them, with Tailwind, lucide-react, recharts, shadcn/ui, d3, three.js, lodash, papaparse and more.
  • SVG, Markdown and Mermaid diagrams.
  • Artifacts that save data with Claude's storage API keep working: personal data per signed-in viewer, shared data per post.

Every artifact runs in an isolated sandbox on a separate domain, so it can never read your ArtiGram account.
