A UI framework for building rich, interactive app surfaces in Slack using stackable JSON components.

Block Kit streamlines Slack app development by replacing legacy attachments with a modular UI framework. Developers assemble layouts using 15+ distinct block types (such as section, input, and accessory) to build modals, home tabs, and complex message threads. It supports interactive elements like date pickers, multi-select menus, and radio buttons to drive user workflows directly within the client. By utilizing the Block Kit Builder for prototyping, teams can rapidly iterate on JSON payloads that ensure consistent rendering across desktop and mobile interfaces.

### [Lazy Marketing v3: From Meeting to Content Pipeline in Zero Click](https://seattle.aitinkerers.org/talks/rsvp_TtXOReDjy68)

Most of us have 10+ meetings a week full of insights worth sharing — but turning those into content never happens. Marketing Machine fixes that by wiring together Claude, Gemini, Slack, Google Sheets, and the LinkedIn API into a fully automated content pipeline. A Read.ai transcript hits a webhook. Claude extracts the best marketing hooks and expands them into on-brand LinkedIn posts using a 100+ line brand-voice prompt. You pick and refine posts entirely inside Slack with buttons and modals — no separate app needed. Gemini generates an accompanying image. Approved posts queue up in Google Sheets and auto-publish to LinkedIn on a schedule. In this demo, I'll walk through the full loop live — from raw meeting transcript to a published LinkedIn post — and dig into the prompt engineering, multi-model orchestration, and Slack-as-a-UI patterns that make it work. Built with Node.js, Express, and APIs anyone can sign up for. No GPUs, no fine-tuning, no ML infra required.
