The tool aims to provide a collaborative writing surface where humans remain editors, with features including real-time collaboration, markdown-native editing, and one-click publishing to CMS platforms.", "body_md": "# The writing workspace your AI can actually write in.\n\nConnect Claude Code, Cursor, claude.ai, or Cowork — and your agents work in the same project as you. They read your notes, draft into your documents, and propose edits you approve, with every change signed so you always see who did what. You stay the editor.\n\nNo credit card · Free plan · Works with Claude Code, Cursor, claude.ai & Cowork\n\n### Q3 Research Notes\n\nFindings from the EMEA pipeline review, summarised for the board deck.\n\nRevenue grew 12% in Q3. 18% QoQ, led by EMEA.\n\nSee it in action\n\n## See it in 90 seconds.\n\nClip three sources, let your AI draft inside a Syncpen doc, approve its edits, and publish — without leaving your workflow.\n\nHow it works\n\n## From your AI to published, in three steps.\n\n01\n\n### Connect your AI\n\nAdd one config block to your MCP client — Claude Code, Cursor, Cline, Windsurf, or any other. One npm package, one API key; first write in five minutes. Cloud clients like claude.ai and Cowork connect to our hosted URL instead — no install.\n\n```\n{\n  \"mcpServers\": {\n    \"syncpen\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"syncpen-mcp\"],\n      \"env\": { \"SYNCPEN_API_KEY\": \"sp_your_key_here\" }\n    }\n  }\n}\n```\n\n02\n\n### It works in your documents\n\nIt searches your library for context, drafts new documents, and proposes changes as tracked suggestions. It can read and answer your comment threads, too.\n\n03\n\n### You approve and publish\n\nAccept or reject each suggested change, then ship to WordPress, Ghost, or Sanity. Every edit your AI makes is signed.\n\nThe agent layer\n\n## Your agents propose. You approve. Every change is signed.\n\nRun several agents in the same project and you still see every change, who made it, and approve it — the human-and-agent review surface no other MCP writing tool ships. This is the wedge.\n\nthe metric is roughly 12%\n\nthe metric is 18% QoQ\n\n### Track-changes, born agent-first.\n\nYour AI suggests edits; you accept or reject each one. It never overwrites your words silently — the original stays until you say so.\n\nIs this number current?\n\nUpdated to Q3 — yes. · Claude\n\n### Comments as a conversation.\n\nLeave a note in the margin and your AI answers right there in the thread — not buried in a terminal log.\n\nversion history\n\n### Signed and attributed.\n\nThe version history shows who wrote what, human or AI — so a shared document never leaves you guessing.\n\nAlso a great editor\n\n## Also a genuinely good place to write.\n\nWith or without an AI in the room.\n\n- Real-time collaboration\n- Multiple cursors, live presence, and role-based sharing.\n- Markdown-native\n- Write in markdown, stay in markdown. No lossy conversions.\n- Built-in research\n- BibTeX, Zotero, and Mendeley import, with automatic bibliography.\n- One-click publishing\n- WordPress, Ghost, and Sanity, plus PDF export.\n- Minimal by design\n- The calm alternative to all-in-one bloat.\n\n“Why not just use…”\n\n## Each tool is great at its corner. Syncpen is the combination.\n\nThe middle column names each tool’s real strength — not a knock. Syncpen’s pitch is the combination, and being the one your AI can work inside.\n\n| If you use… | What it’s great at | What Syncpen adds on top |\n|---|---|---|\n| Google Docs + a CMS | Easy sharing and editing | Native markdown that publishes to WordPress, Ghost, or Sanity in one click. |\n| Notion | A flexible all-in-one | True markdown, a focused writing surface, and an AI that writes in your docs. |\n| iA Writer / Ulysses | A beautiful, focused writing feel | Real-time collaboration and one-click publishing. |\n| HackMD | Markdown with live collaboration | A review surface for your AI — edits arrive as signed suggestions you accept or reject, not silent writes — plus one-click CMS publishing and citations. |\n| A vector DB for agent memory | Fast similarity search | A knowledge base your agent writes to that you can open, read, and correct. |\n\nIf you use Obsidian\n\n## The graph you love — but your whole team writes in it.\n\nObsidian is the best single-player, local-first vault. Syncpen is the collaborative one: the same linked-notes graph, except your team and your AI work in it together, in real time — and you publish straight from it.\n\n### Obsidian\n\nBest as a single-player, local-first vault.\n\n- Plain markdown files on your own disk — offline and private\n- A graph of your personal vault\n- 1,400+ community plugins and themes\n- Native desktop and mobile apps; free for personal use\n\n### Syncpen\n\nthe collaborative oneThe same graph — shared, in the cloud, with your AI in it.\n\n- A shared graph — your whole team’s linked notes, not just one private vault\n- Real-time co-editing with comments, @mentions, and roles\n- Your AI writes in it — a built-in MCP server; edits arrive as signed suggestions you approve\n- One-click publishing to WordPress, Ghost, and Sanity\n\nPrefer plain files on your own disk, fully offline, with a huge plugin ecosystem?
