Ghostwriter — Find what's worth saying. Say it in any voice.
A Notion Custom Agent that automates your entire X/Twitter content workflow.
What makes it different:
Real-time scanning: Custom MCP server connects to X, pulls trending posts from accounts you follow. No copy-paste, no manual research.
Multi-voice generation: 6 built-in voice templates. Write like Karpathy, Elon, Paul Graham, Naval, Sam Altman — or define your own. Switch in one command.
Self-evolving: Every time you edit a draft, Ghostwriter diffs your changes, extracts patterns (hook style, sentence length, tone, closing), and stores them in a Brain database. Next draft is closer to how you actually write.
One-click publishing: Post directly to X from the Signals board. Draft > reviewed > posted — full pipeline in Notion.
Template-ready: Download and start using immediately. Brain DB comes pre-loaded with settings, voice templates, and format rules. Zero setup.

If you're on Contra, you probably know the pain of spending two hours on a proposal that never gets read.
That's why I built the Freelance Gig Agent, a Notion custom agent that helps you qualify, analyse, and review opportunities, then drafts tailored proposals and Loom note ideas for the ones worth pursuing as requested.
You paste a job. It does the thinking.
What it does:
→ Scores every opportunity across fit, competition, and client readiness
→ Flags green and red flags based on your profile
→ Writes a tailored proposal in your voice
→ Saves everything to your applications database automatically
→ Searches for new opportunities when you ask (limited by search access, but the agent can guide an automation setup)
Built for: Freelancers and independent consultants who apply to multiple opportunities and want a system that thinks with them.
Hope you enjoy it and if you use it, I'd love to hear how it goes. DM me here or on LinkedIn!

The Content Planner is a Notion Custom Agent that helps creators and entrepreneurs build a complete content strategy — from scratch, in minutes.
Here's how it works:
Step 1 — Editorial Profile
On first use, the agent asks 5 quick questions: your content pillars, target audience, active platforms, tone & style, and posting frequency. Everything is saved in a dedicated page so the agent remembers your context for every future conversation.
Step 2 — Content Calendar
Ask for a content plan, and the agent generates a full calendar in table format — with dates, working titles, platforms, formats, and pillars. Ready to execute, day by day.
Step 3 — Detailed Outline
Pick any post from the calendar, and the agent builds a structured outline — with a hook, key points, and actionable takeaways. Everything you need to write the post yourself, fast.
The Content Planner is the most downloaded community agent on the Notion Marketplace, with nearly 5,000 downloads. It's available in English and in French.
Built by Marie Gautron — Notion Ambassador, Consulting Partner & Recommended Template Creator.
