As answered by people managing Resonate AI and Opalstack.
Resonate AI's answer
Resonate writes LinkedIn posts from the work you're already doing. It connects to Notion, Slack, GitHub and 15+ other tools, pulls post ideas out of what's actually happening in your product, drafts them in a voice model trained on your writing, then scores every draft with three AI agents before it goes live — so you know how a post will land before you publish it.
The part nothing else does: Resonate runs over MCP. Connect it to Claude, Cursor or n8n and you can fetch context, draft and publish from inside the AI tools you already work in.
Resonate AI's answer
React front end, Model Context Protocol for the AI-tool integration layer (Claude, Cursor, n8n, Zapier), Cloudflare Workers, and the LinkedIn API.
Resonate AI's answer
Three practical reasons.
No ban risk. Resonate uses no Chrome extension, no cookie-based auth and no scraping — the mechanisms behind documented LinkedIn account warnings for tools like Taplio.
It sounds like you. AuthoredUp formats but doesn't write. Buffer treats LinkedIn as one channel among many. Resonate trains a voice model on your existing posts and runs a dedicated Voice agent against every draft, so generic AI phrasing gets caught before you see it.
Price. Resonate starts at $29/month with a 14-day trial and a 30-day money-back guarantee. Taplio's AI features start around $65.
Resonate AI's answer
Two groups.
Founders and operators who know LinkedIn matters but never get round to posting — the ones whose expertise is genuinely worth reading and completely invisible.
Agencies and ghostwriters managing multiple clients, who need a separate voice model per client, magic-link approvals and white-label reporting without paying for a seat per person.
Both share the same problem: the ideas already exist in the work, nothing pulls them out.
Resonate AI's answer
We couldn't find a tool that actually sounded like us.
We knew LinkedIn moved the needle for our careers and our startups, but posting was always the thing that slipped. Every tool we tried produced generic AI we'd have to rewrite from scratch. And none of them solved the real problem — the blank page. Our best material was already sitting in our product, our calls, our Slack; nothing pulled it out.
So we built the thing we wanted: connect your work, train your voice, get post-ready ideas every morning. Ghostwriter quality without the weekly call.
