Inspiration

Founders want to post about their startups, and they need different copy for X, LinkedIn, TikTok, and newsletter. What comes back usually sounds like ChatGPT, so they end up editing each platform one by one, which takes a lot of time.

What it does

They paste the draft, set a founder brand voice, and highlight the bits they don't want. ChatGPT on the desktop, through WebMCP, reads that same highlight and those same rules and writes the four social posts so all four follow the voice.

How we built it

Next.js static export, Zustand and sessionStorage, and tone scoring in the page. Six tools on document.modelContext.registerTool: get_workspace, inject_brand_rules, analyze_tone_deviation, generate_platform_variants, rewrite_selection, schedule_cross_post. ChatGPT writes into the desk and Cloudflare Workers hosts it.

Challenges we ran into

The build went smooth. ChatGPT opened /desk, the tools showed up, and the four boxes filled.

Accomplishments that we're proud of

Founders set a voice, highlight what they don't want, and get four posts that follow the same rules on a live desk.

What we learned

WebMCP only works if ChatGPT reads the same draft and the same highlight the founder is looking at.
